Uses Of Wind Energy Wikipedia

Maria asks…

How do wind turbines work to store/distribute energy?

Windmill Farms answers:

I dont want to copy the entire article from the site—please do visit the link below for full information

A wind turbine is a machine for converting the mechanical energy in wind into electrical energy. If the mechanical energy is used directly by machinery, such as a pump or grinding stones, the machine is usually called a windmill. If the mechanical energy is then converted to electricity, the machine is called a wind generator



Ken asks…

Evaluate the advantages and disadvantages of using direct solar energy ?

Evaluate the advantages and disadvantages of using direct solar energy to heat buildings and water, and to produce energy.

Windmill Farms answers:

The sun is providing free energy every day. How much energy depends mainly on the latitude and to some extent on climate. The question that you are asking is to evaluate our use of this energy to heat buildings and water and presumably other uses.


This energy is free at source and is totally renewable, as far as we know for thousands of years.


To harness this energy we need to employ materials and resources and to use our ingenuity to provide technical solutions appropriate to the economic and physical situation and location. There is a capital cost and possibly maintenance costs.

The actual harnessing of the energy can only happen in daylight hours so there may be problems of storing the energy at night.

The advantages are greatest in hot sunny climates but the need for energy is often greater in colder, northern or southern latitudes.


What are the methods that we can use? Where are the different methods most appropriate?


For buildings we need to consider internal climate control and hot water supply and for both these we can use passive and active methods. It is also much easier to incorporate suitable provisions into new domestic, commercial and public construction, although significant improvements can be made to existing buildings.

Passive methods: The four methods for domestic construction in the northern hemisphere that make use of greenhouse effect are:
South facing windows (large windows on south, small or none on north side) other elevations as appropriate with solar shading or solar glazing and thermal insulation.
South facing roof space: usually pitched roof used as a solar collector. May need small fan and duct to circulate hot air.
Conservatory: South side glazed volume.
Trombe wall. South glazed wall with heavy masonry or concrete wall painted black.

And for larger buildings one might use a climate wall i.e. Glazed external wall with significant air space between external and internal wall (internal wall can be fully or partially glazed or incorporate thermal mass for storage of heat)

Active methods use solar voltaic panels or solar collectors with water pumped to storage or direct use. Thermosiphon systems, where the storage tank is placed above the collector, do not need a pump and are therefore regarded as a passive system. Standard units are used for hot water supply throughout the Mediterranean countries and middle east. The use of thermal chimneys is also an anchient passive method of internal climate control with modern uses.

This is a very big subject and I have only touched on a brief outline. One could also discuss earth sheltering, construction methods, sustainability, low technology methods for emerging third world countries such as solar ovens and all sorts of related subjects.

Although all the above information is from my own personal knowledge, I have used references in the past such as Wikipedia, (on line encyclopaedia) the Energy Trust Website (a non- profit making Trust based in London) and for low cost energy saving
technology: This site offers a manual for building your own solar power array and wind turbine, with sources for free batteries and claims to save you 80% on electricity costs. In the future I think we will have better gas fired boilers that are not only more efficient like condensation boilers, but combine heating and power generation, so that you will be able to sell back your surplus electricity to the national grid in Britain or the power utility company in USA and Canada. Meanwhile we have to rely on the present technology and in cold climates improved insulation or more heavily insulated new construction, double or triple glazing. Solar methods can be quite useful depending on the payback period. Heat pumps with ground collection systems usually take longer to payback and depend on your having a large volume low energy heat source such as a large pond or coils in the ground. Wind energy is another useful method, and although intermittent can have an acceptable payback period.

John asks…

What are some alternatives to using fossil fuels to generate elctricty?

How do they work???

Windmill Farms answers:

Wind _ wind spins turbines to produce electricity
Solar – solar energy heats up water which is then used to produce energy
Hydro – running water spins turbines to produce energy
Tidal – rising and falling water, ocean currents and waves spin turbines to produce energy
Geothermal -Heat from the earth’s interior is used as an energy source
Biofuels_-algae and grease are burned to produce energy

Betty asks…


i have to name a stakehoder that would be FOR and one that would be AGAINST wind power?

i will expand on it myself just need to know this :s


Windmill Farms answers:


1) The nuclear industry.

Wind power requires backup power generation for use when the wind is not blowing hard enough. It reduces the amount of fuel consumed by the backup power source by allowing the substitution of wind energy. Fossil fuel generators have low overhead, but high fuel costs. Nuclear power generators are just the opposite. While the overall cost of nuclear generated electricity is greater than fossil fuel (coal and gas) generated electricity,

the fuel costs of nuclear generated electricity is only one third of the fossil fuel generated electricity.


Thus, the only cost advantage attributable to nuclear power is lost when wind power is introduced into the equation.

2) Terrorists: Nuclear power plants generate fissionable materials that can be used to make either dirty bombs, or nuclear bombs. The materials can be used simply to contaminate crops, reservoirs, and urban areas. In addition, nuclear facilities make juicy targets that have been exploited by terrorists in the USA before:

Nov. 10, 1972

3) AGW alarmists: These people believe that the threat of burning CO2 producing fuels is so dangerous that setting up systems that promote the construction of fossil fuel burning power stations instead of nuclear ones would be a bad idea. Thanks to agreements emanating from Copenhagen, we now have agreements that mandate the construction of nuclear power plants just about everywhere without mentioning nuclear. Genius!


4) Fascists: Fascists can use the enhanced security risks of nuclear power plants around us as an excuse to take away our constitutional rights.


1) Utilities who are not nuclear, and are not going nuclear.
2) Rate payers.
3) Insurance Companies would be for wind power in that they would lessen the likelihood that nuclear power plants would be built. Insurance companies get to sell insurance to all power generating facilities except nuclear plants who are insured by the US federal taxpayer:

4) US federal taxpayers:
Tax Payers not only pay the insurance for nuclear power generators, but also pay to dispose of their waste:

Laura asks…

How does a wind turbine generate electricity?

im making a diagram upon how wind turbines generate electricty
so please help me to like create. i know the wind turns the blades which creates electricity via the generatore. but how does it occur.
what type of energy is used. EG kinetic, thermal?

/thank you xxx

Windmill Farms answers:

A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind turbine generator (WTG), wind power unit (WPU), wind energy converter (WEC), or aerogenerator.

Wind Energy Companies

Mary asks…

How can I start an energy company?

I am interested in starting an energy company. I live in Pennsylvania now but I hope to move to Texas soon. Anyhow I plan to start off small obviously but eventually I want to build up. I would like to do a few things eventually, Maybe someone here knows where I should start. My dream is to own a large energy company that will have its own large office building in Dallas, TX and will supply energy to a lot of cities in the South and Southwest sections of the country. I want to pump and distribute oil and well as own power plants across the southwest that utilize solar, wind, oil, and other forms of energy. If I grow large enough (if this happens it would probably be the work of my kids and grand kids) but I would then like to start building nuclear. Obviously this is a very huge goal but I am sort of testing the waters and now I believe is a good time to start. I just need to find a way to obtain some capital and create a solid business plan. If anyone has any ideas how I could begin to develope and plan this out please leave a comment.

Windmill Farms answers:

Well you just don’t move to Texas and start an energy company with power plants, pumps and distribution. That is, unless you have a billion dollars to start with. If you wanted to start small there are a number of oil wells for sale in Texas and Louisiana (and just about everywhere in the 48 states). Of course, you need to know the business before you jump into something like that. You could also try to buy some property for speculation and drill your own well. Chances are about zero that you’ll discover new oil in the south.

The best thing to do is start an alternative energy company. You don’t really have to do anything but collect grants from the government. That’s how people are currently getting rich in energy. If you don’t feel guilty about stealing from taxpayers then this might be a good option.

Ruth asks…

Who are primary consumers of wind energy?

Windmill Farms answers:

There are many energy company that are moving to wind energy to help fight global warming right now and it depends on were you are located to were you would be able to get it. There are many homes and businesses that are moving over to wind energy. I just talk about this on my website at If you would like to look it up there to have a better understanding about wind energy.

Charles asks…

Wind energy distribution and wind energy in spain?

I would like to know how wind energy is transported from the wind farms to our homes. Also, what appliances could wind energy support? Could you also add some info about wind energy in spain as that is what my project is about. Any help will be greatly appreciated

Windmill Farms answers:

Wind energy is not transported but TRANSMITTED. These are also known as wind turbines.the blades move with the help of wind with particular speed on which the generator build the electricity,this electricity is then transmitted to the transformer to step down and connected conductors (wires)lead them to residential area by the help of poles.the electricity reaching to you,no one out side of the power plant can tel its from wind turbine,nuclear power plant,thermal power or any other………from all types the electricity is transmitted after transforming(step-up or step-down),the frequency and voltage is kept as recommended for any country……so no one finds any difference in difference means appliance need electricity which is in particular frequency and voltage,if you provide it according to its need it will work,weather its from wind power plan or thermal.

Renewable energy in Spain

Spain is the world’s third biggest producer of wind power, after the United States and Germany, with an installed capacity of 16,740 megawatts (MW) at the end of 2008, a rise of 1,609 MW for the year. The largest producer of wind power in Spain is Iberdrola, with 27 percent of capacity, followed by Acciona on 16 percent and Endesa with 10 percent. Steady growth in capacity is expected in 2009, despite the credit crunch, due to long-term investments. Spain’s wind farms are on track to meet a government target of 20,000 MW in capacity by 2010.

On particular windy days, wind power generation has surpassed all other electricity sources in Spain, including nuclear. On April 18, 2008 the all time peak for wind generation was seen (10,879 MW, 32% of Spain’s power requirement),and on November 24, 2008 the wind energy produced the 43% of the demand.Wind power is an important energy source in Spain because the Spanish government has sanctioned a green energy approach to guarantee an increase in the country’s wind generation capacity, with aspirations to install a total of 20.1 GW of wind power by 2010.The approaches of energy deregulation that have been initiated in Spain recently are generating noteworthy developments within the energy sector. Multilateral cooperation for involvement in wind power production throughout Europe has created investment prospects for the industry and lower energy costs due to the efficiency of the renewable energy source and its domestic availability.
“The business framework for the installed capacity of wind power in the Autonomous Regions was made up of more than 170 companies that included manufacturers (wind turbines, blades, towers, generators, multipliers, electrical equipment, etc.), suppliers (hydraulic and electrical equipment and equipment for controlling and regulating), mechanical construction and public works companies, installation companies and maintenance, exploitation, and engineering companies in 2003”.
“Spanish companies are leading the way in turbine innovation by increasing the size of turbines while reducing turbine weight, and are also developing new technologies to take advantage of wind changes and split-second power outages”.

David asks…

What are some wind energy stocks?

I know GE has a hand in the wind energy sector, but what are some public traded companies that wind energy is their main focus? I know that there is a Brazilian company called Tecsis, that I see their turbine blades on trucks headed somewhere all the time.

Windmill Farms answers:

Vestas Wind Systems is one of the largest. A Danish company. Traded on the pink sheets ticker VWSYF. There is also a Spanish company Gamesa also on the pink sheets GCTAF. An Italian company Nordex AG also on the pink sheets NRDXF. There is a BB company call Broadwind Energy ticker BWEN–very speculative.

A company that is involved is Hansen Transmission NV ticker HSNTF on the pink sheets. It is a Belgian company that makes the transmissions for wind turbines.

Daniel asks…

what is wind energy and what are good things about it?

Windmill Farms answers:

The use of wind turbines can be a great way to provide a source of clean and renewable energy for your home or business. There are a number of small wind energy devices that you can use to generate power and these can be very cost effective in providing a significant level of electricity.
Many people in the UK are investing in wind energy technologies in addition or as an alternative to solar power. Wind energy is also a key ingredient for the United Kingdoms’ future energy growth and the plan to reduce carbon emissions. If you’re concerned about the environment and would like to make a difference then the use of a home wind turbine is a good place to start. Depending on your location you can implement an efficient renewable energy system utilizing a combination of both wind and solar power. Solar panels can be more effective than a regular home wind turbine, yet both devices offer a way to generate renewable electricity in a wide variety of locations. You should always consult a renewable energy company that has experience in the design and installation of wind energy systems before going ahead with any development as the wind may not be a viable source of energy in your location and a reputable renewable energy systems company should be able to identify this and provide an alternate means of generating renewable energy suited to your location.
The installation of renewable energy technologies such as; wind turbines, solar panels, and even geothermal systems can all contribute to helping you save money on your energy bills. You can pick up a cheap, low output wind turbine for as little as £200 to £400, depending on how much power you wish to generate.

Saving Energy?

Ok I need some tips on saving energy here are some questions:

Is there a surge protector that is energy efficient?
How can I save energy while on the computer?

Please give me more tips as well!!


Windmill Farms answers:

I have a HUUUUGE list available at www agua-luna com it’s like 33 pages long and would just spam this whole answer. But here’s a few cut from the list below. If you’d like the entire list feel free to visit www agua-luna com or email me through the site directly and I’ll send you a copy.

Also Agua-Luna com now offers Carbon Offsetting Credits, since our Team of Volunteers is already accomplishing several carbon eliminating projects, we’re now converting the carbon offsets to you. Visit www agua-luna com for a FREE carbon calculator to calculate your carbon footprint for free and more info on carbon credits.

You could also Volunteer with us, planting a tree or working on a Sustainable Renewable Energy Building Project in Mexico with us. Again see www agua-luna com for more info.

I also do some free consulting, there’s more info on the site about that too. Here’s some more ways to help the environment…

Recycle paper, cardboard, newsprint and magazines.
Recycle aluminum cans.
Recycle all batteries.
Recycle and reuse. Roughly 50% of the average person’s trash can be recycled. Don’t forget that hazardous waste like batteries, your printer’s ink cartridges, and cell phones can be recycled too! Find out how and where to recycle in your area. Always buy recycled paper. Just 1 ton of recycled paper saves 17 trees.
Just because your community doesn’t pick up all recyclables on the curb, it doesn’t mean there are not viable alternatives nearby. Check with dry cleaners, supermarkets, manufacturers, your local public works department and civic organizations to find out where recycled goods can be dropped off, at a location near you.
Did you know that just in 1995 alone, recycled toner cartridges kept over 21,000 tons of trash out of landfills? Believe it or not, now you can recycle your printer’s toner cartridges! Every year, Americans throw out enough printer cartridges to stretch from Los Angeles to New York City and back again. Toner cartridges can be recycled, having just as good a performance as an unrecycled cartridge. To recycle your toner cartridges, find a local business that does printer cartridge recycling, or contact the manufacturer of your current toner cartridge and ask about a cartridge recycling program.
Not only should you recycle, but buy products that are recycled. By purchasing these products, you are helping to conserve natural resources, and to protect the environment.
Wash clothes in cold water.
Hot water is unnecessary for most clothes. When needed, use warm water.
Fill your toilet tank.
Put a plastic bottle or two, filled with water and rocks, in your tank to reduce the amount of water used in each flush.
Clean your filters.
Clean the filters of your air-conditioners once a month to improve energy efficiency. While you’re at it, change your car’s filters as recommended in your manual.
Get a low-flow shower head.
Stop at the hardware store on your way home, and get a low-flow shower head. Takes a few minutes to install, and it’ll save gallons of water a day.
Lower your thermostats.
If you use heating, get by with less heat and wear warmer clothes. If you use air-conditioning, get by with less cooling and wear cooler clothes.
If it’s a nice sunny day, hanging clothes only takes a few minutes, and you’re using solar power instead of electricity to do the job. It also makes your clothes last longer.
Turn down your water heater.
Most people have their water heater’s thermostat turned up too high, wasting energy. Turn it down to 130 degrees, saving energy but still hot enough to kill bacteria.
Use CFC light bulbs.
If your light bulb burns out, replace it with a Compact Flourescent bulb (those spiral-looking ones). They’re more expensive, but if you just replace them one at a time, it doesn’t cost much, and the energy savings is great. And as they last longer, over the long run, you’ll save money.
Wash and dry only full loads of laundry and dishes.
Follow your community’s water use restrictions or guidelines.
Install a low-flow shower head.
If you are not looking to change your car just yet there are a number of ways you can be more environmentally friendly and help you save money by conserving fuel.
Lighten your car to reduce weight by not carrying unnecessary items.
Cut your speed and stick to the speed limits
Drive smoothly avoiding heavy accelerating and braking.
When stationary for a long time, switch off the engine.
Closing windows will make the car more efficient by being more aerodynamic. Remove roof bars when not is use also helps.
Make sure your tyres are properly inflated as under inflated tyres cause more resistance.
Where possible, walk, cycle or even use public transport.
If possible lift share to reduce the number of cars on the road.
Try mass transit.
Millions of people use it, and it saves tons of fuel. If you don’t already, give it a try.
Unload your car.
Remove excess weight from your car (such as stuff that might be in the trunk) to reduce the amount of fuel you use.
Walk instead of drive.
You don’t have to do this all the time, but walking the short trip to a store, or to lunch from work, or some other short trip like that, can reduce the amount of fuel you use over the long term, and you shed some fat at the same time. Or at least burn off that morning donut.
Buy a smaller car.
You won’t be able to do this today, probably, but the next time you’re in the market for an automobile, get a smaller and energy-efficient car rather than a big, lumbering one. It’s one of the best things you can do to reduce your fuel consumption.
Inflate your tires.
Many people don’t realize that their tires are under-inflated. Check the recommended pressure for your tires, and fill them up to that pressure. It only takes a few minutes, but it will save you on fuel consumption (a little) and more importantly, make your tires last longer and reduce the rubber that’s worn off your tires.
Get creative with gift-giving. The gift of time, services, or environmentally positive gifts may be more appreciated than disposable goods that are not to the taste or needs of the recipient.
Look into those lifestyle changes you’ve been putting off
Work from home more. Many organisations, when prodded a little, will accept flexible work arrangements where there is no impact to the work that needs to get done.
Use your oven less.
The oven not only uses a lot of energy, it heats up your kitchen, requiring more cooling. Instead, use toaster ovens, crockpots, microwaves, and electric grills when you can. And when you do use your oven, open it less – you lose 25% of the heat every time you open the oven door.
Mend your stuff.
Try not to throw stuff away and buy new stuff if the old stuff can be fixed. Torn clothing? Takes a few minutes to sew up.
Install a water filter.
If you buy a lot of bottled water, use your tap instead. Some places need a filter to make tap water taste drinkable, but they don’t cost much and they can save money, water, and plastic bottles over time.
Unplug appliances.
If you don’t use an appliance several times a day, it’s better to unplug it, as they often use energy even when turned off
Use rechargeable batteries.
Instead of throwing your batteries away all the time, reuse rechargeable batteries. Costs a little more, but cheaper in the long run.
When you’re looking to buy appliances, be sure to research the most energy-efficient ones. They may cost a little more, but they’ll more than make up for that in the long run with lower energy bills.
Buy a smaller home.
The next time you’re home-shopping, instead of buying the McMansion, look for a smaller home that’s big enough to meet your needs comfortably. Reducing the amount of stuff you own is a good way to need less house. It’s cheaper, and requires less energy to heat and cool. And easier to clean at the same time.
Look for energy efficiency.
Use acryllic paint.
It’s not hard to set one up (look it up online), and you can save a lot of waste from the landfill and help your garden at the same time
Water grass early in the morning.
Reduces the amount of water you need to keep your grass looking fabulous.
Plant shade trees near your house.
It’ll take awhile before they can make a difference, but shade trees greatly reduce the need to cool a home.
Coat your roof.
This’ll take up an afternoon, but you only have to do it once every few years. And it’ll save you a lot of money and energy in heating and cooling over the long-term, more than making up for the cost of paint.
Avoid fast food.
Instead, eat at home or at a sit-down restaurant. Fast food restaurants are one of the worst polluters of the environment, both in the massive amounts of beef they must raise, in the wasted packaging, and in the energy they use in so many ways. And they’re tremendously unhealthy.
Buy a manual reel mower or electric mower.
If you’re looking for a new lawn mower, and you have a small yard, consider getting a manual one. They’re much advanced from the reel mowers of our grandparents’ generation, much quieter, cheaper, and they save on fuel and pollution. Electric mowers are also quieter and use much less energy.
Clean up.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at www agua-luna com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Good rebuttal with Solar Energy Disadvantages?

Here are some Solar Energy Disadvantages.
I am on the good side in a debate discussing pros and cons of solar energy.
So i need some good facts to cover up these disadvantages!! thankksss

- The initial cost is the main disadvantage of installing a solar energy system, largely because of the high cost of the semi-conducting materials used in building one.

- The cost of solar energy is also high compared to non-renewable utility-supplied electricity. As energy shortages are becoming more common, solar energy is becoming more price-competitive.

- Solar panels require quite a large area for installation to achieve a good level of efficiency.

- The efficiency of the system also relies on the location of the sun, although this problem can be overcome with the installation of certain components.

Windmill Farms answers:

Initial cost- with the state rebates, renewable energy credit system, and federal tax credits, the system will pay for itself in 4 to 8 years depending on what state you live in. Where else could an investment pay for itself in 4 years?

Large area- you don’t need a system that will offset your entire electric usage. You want a system in conjunction with renewable energy credits and electric savings, will offset your entire electric bill.

Location- actually, the earth revolves around the sun. If you don’t have southern facing roof space, you can mount a system in the ground. If that’s not an option, you’re siht out of luck.

If you decide that you want to use an off grid system, a system that uses batteries, you will not be able to receive state rebates and sell excess electricity back to the utility company.

David asks…

What has electronics to do with renewable energy?

Windmill Farms answers:

Electronics used to control load devices has the potential to conserve energy or to increase energy demand.

With either conventional or alternative energy sources, electronic control equipment is used in generating, transmitting and distributing electrical energy. Electronics is used to monitor and control electric generators, and to provide protective functions. Electronic metering equipment is used to record and transmit usage information for billing. High power electronic equipment is used to convert electric power from AC to DC and from DC to AC for high voltage DC transmission lines.

Solar, wind and other alternative electric power generation systems have their own unique requirements for controlling generation, converting between AC and DC, and matching generated voltage and frequencies with usage and grid requirements. Both high power and control level electronic circuits are required. Alternative electrical power generation systems increase the benefit that can be gained by electrical energy storage. Electronic charge and discharge systems are needed for energy storage. Alternative energy systems also increase the need for computer controlled “smart grid” systems.

Here is the description for a one semester three credit course that is essentially a survey course that introduces the student to the electrical and electronic engineering requirements of alternative energy systems.


Donna asks…

Why do republicans block scientific and renewable energy progress?

It seems like anything to get us off oil dependency, the republicans hate.
Me-owww thts just it, reps dont do shit when it comes to renewable energies
i agree with one thing, obama isnt all tht great, he is better than bush by far, but he isnt much better, we need a pres like JFK
LadyB, I agree with you, I watch all the news channels, i myself am very educated in u.s. history. I was watching fox news, am right now, they by far spew the most lies. MSNBC and CNN do to, but not NEAR as much

Windmill Farms answers:

If you start with a factually inaccurate question you can not possibly get a factually accurate answer….

Even the fat Republican icon Rush Limbaugh has publicly supported cleaning up the planet and developing renewable energy…..

Most Republican and Democrats support scientific and renewable energy progress…..

“i myself am very educated in u.s. History.”…..then you must know it was JFK who started the Vietnam War….. And a Democrat Lyndon B Johnson who expanded into a tragic farce…..that all the major wars (Spanish War; Mexican War; Philippine Insurrection; WW I , WW II , Korean War etc) America has been involved in (except the war on terror and the civil war)….were started by Democrats

FOX news……. Bill O’Reilly is NOT fox news…..Sarah Palin is NOT fox news…..Sean Hannity is NOT fox news…..Glen Beck is NOT fox news…. They are “entertainers”…..people who express their opinion…..their often BIAS opinion…..but they have nothing to do with FOX news…. FOX news is actually “fair and balanced”….. And even Bill O’Reilly allows the opposition to tell their side…..FOX news does not spew lies

Name one thing JFK did to improve life in America……??? At least during seven years of the Bush administration America had no terrorist attacks on any American anywhere in the world…..we have had four terrorist attacks under Obama

LADYB…. Have you read the University of Maryland survey?…
–Most economists estimate the stimulus caused job losses
–Most economists have estimated the health care law will worsen the deficit
–The economy is getting worse
–Most scientists do not agree that climate change is occurring
–The stimulus legislation did not include any tax cuts
–Their own income taxes have gone up
–The auto bailout only occurred under Obama
–When TARP came up for a vote most Republicans opposed it
–And that it is not clear that Obama was born in the United States

Most of these questions are subject to debate or use tricky words…. The word “most’ is quantitative and not something many people would know regardless of the source of their knowledge….BUT someone who disagreed with the basic premise of the question would not be bothered by the word

In other words the University of Maryland either was sloppy in formulating the survey or specifically wanted a certain response…. A certain result….. Kind of a play on the old “Do you still beat your wife?”…..

Actually the stimulus bill gave tax credits….. And to the wrong people….. It is formulated on OLD Keynesian economics and useless as an economy stimulus in a globalized world….

EDIT “Thumbs Down’…. Now that was a surprise……(sarcasm)….. Please post a correction….. Do not let me mislead the readers

Joseph asks…

how does the federal renewables tax credit work?

I saw that the energy efficiency tax credit only reduces your tax liability but does not put any money back in your pocket. I am curious if I put a solar system on my house if the process and outcome is the same. I can’t get my accountant to call me back and I am not finding the specific publication that explains the process in more detail online.

Windmill Farms answers:

Residential Energy Efficient Property Credit (Section 1122): This nonrefundable energy tax credit will help individual taxpayers pay for qualified residential alternative energy equipment, such as solar hot water heaters, geothermal heat pumps and wind turbines. The new law removes some of the previously imposed maximum amounts and allows for a credit equal to 30 percent of the cost of qualified property. See Notice 2009-41.


On-Site Renewables Tax Incentives
Solar Energy Systems – Small Wind Systems – Geothermal Heat Pumps
Solar Energy Systems
What are the tax incentives for solar systems?
Homeowners are eligible for tax credits for qualified solar water heating and photovoltaic systems. Solar water heating systems produce hot water, photovoltaic systems produce electricity (including solar fans). The credits are available for systems “placed in service” at any dwelling unit, not necessarily the primary residence, between January 1, 2006 and December 31, 2016.

Note: This is a basic guide to the credit. For more detailed information, go to and download the Guide to Federal Tax Incentives for Solar Energy, or SEIA’s FAQs regarding the new legislation.

How do the incentives work?

Alternative Minimum Tax and the Residential Solar Tax Credit

According to SEIA, the new legislation passed in October of 2008 “allows individual taxpayers to use the credit to offset AMT liability, and to carry unused credits forward to the next succeeding taxable year.”

What do I have to do to qualify for these incentives?
To qualify, tax payers will need to have evidence regarding:

PLEASE explain why and talk about the pros and cons. Try to mitigate or solve each con. For example, if you chose solar power, is there gonna be no power all the time at night? PLS i need opinions.

Windmill Farms answers:

Nuclear Power
Nuclear power plants can be built almost anywhere, very safe, very reliable, small environmental impact. Nuclear power plants can operate 24 hrs a day 340 days a year. A very small amount of fuel produces a large amount of energy without producing any greenhouse gasses, particulate or other pollutants.

Robert asks…

How is wind power better than other power souces? What pro and cons can wind do for the envirooment?

Windmill Farms answers:

Wind power is basically a derivative of solar energy, since the wind is created by differences in solar radiation and the resulting pressure changes in the atmosphere. For this reason, it is considered a renewable energy source. It is not true that wind power produces NO form of pollution or emissions, since the manufacturing process consumes both resources and energy, and if batteries are combined with the installation, considerable amounts of toxic waste are created by the batteries.

Wind has an advantage over solar because it is not limited to daylight hours. However, wind power can be fickle and many times I pass large wind farms that are not generating power because of a lack of wind. The unpredictable supply is a significant drawback. Power consumption tends to be very predictable and often peaks at times when wind power is at the lowest level, such as during very high pressure that produces high demand for air conditioning. Since there is no easy way to store electricity wind power is only capable of being a supplement to the power grid. Installations that depend on wind power must install large banks of batteries and hope that the batteries will store enough power to last until the wind blows again.

Cost recovery for wind power is currently not competitive. The cost I see quoted most often is about $0.09/ kw/hr which is typically higher than most utilities charge the consumer today, meaning to have this cost as a wholesale cost is not competitive. Currently the only way commercial wind power generators make money is because of tax subsidies.

Wind generators take considerably less energy to manufacture than solar cells, which take so much energy that estimates range from 4-20 years before the energy generated covers the energy consumed in manufacture.

Two significant drawbacks for wind generators have been that both birds and bats (often endangered) have been killed by wind generators. The bat problem has forced some wind farms to close down or move. Bird migration has been a problem for some wind farms, but there appear to be methods of alleviating this. One idea that holds promise is to use vertical wind generators that often have significantly smaller area for a bird or bat to collide with.

So far there has been a surprising amount of resistance to installation of wind farms. The most well-known example was the proposed offshore wind farm off of Cape Cod. Even Senator Kennedy opposed this one. In other areas people who tried to get permits often find that most municipalities will not allow wind generators due to some zoning code such as height restrictions or some other limitation. Ironically, wind mills were and still are used all over the rural western US for pumping water for livestock, since the 1800′s.

Maria asks…

What questions should one ask before forming an opinion about Nuclear Energy?

I’m supposed to write a paper explaining my opinion about Nuclear Energy and whether we should use it or not. Before just gathering Pros and Cons, I want to gather questions that I should find answers to, like cost, how efficient, is it renewable, etc. I’m not necessarily asking you to answer these questions, but help me come up with some.

Thanks in advance =]

1. How does it compare to alternative methods of producing energy?
Safety record, environmental impact, sustainability, cost, and risk/benefit?
Nuclear Pros and Cons
!. Fission is the most energy for the least fuel with current technology.
2. Less fuel means less waste, and the waste is all accounted for, not released into the atmosphere to become someone else’s problem.
3. Uranium is readily available, very common in the earth’s crust (about the same as tin)
4. Economical – operating cost about the same as coal, fuel cost is a much smaller percentage of the total, therefore less susceptible to price fluctuations.
5. Reliable – Nuclear power plants have very high capacity factors, Much higher than solar
6. No combustion, no Co, CO2 or SO2 released.
7. Creates high paying, skilled jobs.
8. Reduce dependence on foreign oil/ fuel. Uranium available domestically and in oceans.
9. High temperature reactors could produce Hydrogen as well as electricity.
10. Fantastic safety record.
11, Does not require back-up and storage facilities like solar and wind.
12. More economical than solar per Mw produced.
13. Much smaller footprint, takes up less land than Solar or wind.

1. Irrational fear of all things nuclear.
2. High cost to build and license, large initial investment for long term pay back.
3. Publicly accepted high level storage facility not domestically available.
4. Reprocessing facility not domestically available.
4. High cost of personnel.
5. Security concerns, proliferation and terrorism.
Nuclear power, I believe is the best, safest, most reliable, current technology to provide energy. The plants operating now are safe and the new designs are even safer.
Building 100′s of new nuclear power plants would improve the economy, reduce or eliminate dependence on foreign oil, create jobs, reduce pollution, and provide for future technological advancement.
I have been working with nuclear power for about 30 years, I would be glad to have a Nuclear power plant or high level waste disposal facility in my backyard. My family and I live in a home within 10 miles of a nuclear power plant. (where I work) I have a great understanding of the risks involved and am completely comfortable with a plant “in my backyard”.
Using Chernobyl as a reason not to build is like saying because of the Hindenburg I will never fly in a commercial airliner.
Nuclear power has the smallest environmental impact of any current energy production method per unit of energy produced. One fuel pellet about the size of a pencil eraser produces the same energy as about 1 ton of coal, and if reprocessed 2/3 of what’s left can be reclaimed. Nuclear power is our best option for reliable, environmentally friendly, base-load electrical power.

Vertical Wind Power Generators

Mark asks…

how should the magnets be place in a wind turbine generator?

i have been building a vertical-axis wind turbine and everything is spinning well.But the problem is that its not generating any electric power.I think the problem is with the magnets or the copper coils, but i’m more sure that the problem is coming from the magnets.I don’t know how to place the poles(i have cylinder shaped magnets; they are really strong).Whenever i pluck the 2 copper coil poles to the volt-meter, it gives me the same current i get when ever i put the 2 wires on each other(when it gives me the voltage of its battery).
For further information:
im using some really thick copper coils, and they are twisted in the right shape but not 100% organized.
Anything would be helpful..
Thank you :)

Windmill Farms answers:

I assume your rotate one whole piece cylinder shaped magnet in the center of a coil with wind turbine.
The coil should be a little bit bigger than the magnet cylinder and the coil should be also in cylinder shape. The coil direction must be in vertical against the magnetic field. Show the photos of your design
could be more easily for me to locate the problem.

How do wind turbines work? HELP!?

Its for homework and i have to say how wind turbines work. my teacher said that there is a generator and a MAGNET in it? PLEASE INCLUDE THEM AND PLEASE SAY IT SIMPLY! i need a breif explanation :) thanks xx

Windmill Farms answers:

There are actually two distinct types of wind turbines that are currently in production, with several other varieties also theorized. The two main categories of wind turbines are vertical axis wind turbines and horizontal axis wind turbines. Although these two different types of wind turbines work using relatively similar methods, there are key differences in how they function as well. Along with these two major categorizations there are also many different kinds of wind turbines that exist to operate in unique conditions
How Do Horizontal Axis Wind Turbines Work?
Horizontal axis wind turbines are by far the more prevalent type of wind turbine in use today and historically speaking. Windmills, for example, use a horizontal axis wind turbine to power themselves, as do most modern wind-farm turbines. Horizontal axis wind turbines work by facing propeller blades into the wind on a horizontal rotor shaft. The action of the wind causes the blades to spin, much like a pinwheel. The blades are fixed and are connected to the rotor shaft, which rotates with them in the wind. The motion of this rotor shaft can then be used to do work of some kind or, in more modern applications, to generate electricity.

How Do Vertical Axis Wind Turbines Work?
Vertical axis turbines work on very similar principles to horizontal axis wind turbines, but with several key distinctions. To begin with, the rotor shaft of a vertical wind turbine is arranged in a vertical fashion, with the wind-catching blades arranged around the rotor shaft. Vertical axis wind turbines do not need to be facing into the wind to work because the blades are arranged uniformly around the rotor shaft and can catch the wind from any direction. The blades catch the wind, spinning the entire apparatus in a circular motion. The energy created by this kinetic effect can then be used to either do work or to create electrical energy.

Paul asks…

How would you calculate the theoretical power output of a Savonius wind turbine?

I built a small scale Savonius style wind turbine for a project. I can easily measure the power it puts out in a wind tunnel using a wattmeter, but how would I calculate the theoretical maximum power output? I want to use these two values to find the turbine’s efficiency. Thanks!

Windmill Farms answers:

Hey Drew, Gatorbait is on the right track, but the formulas in Mr. Voneshen’s publication cannot be used for a savonius turbine.

First, the actual formula originally derived by Albert Betz was this:

P = .5 X rho X A X V^3

P is power in watts
rho is the air density in kg / cubic meter
A is the swept area in square meters
V is the velocity in m/s, which is cubed to get the final power.

This is the actual formula to find theoretical power available in a moving column of air. There are lots of hybrid formulas, such as the one Gatorbait references. Mr. Voneschen’s instructions use one that takes air density at sea level times one half, then converts it to a constant to adjust for the fact that he is using Diameter instead of swept Area. That’s fine, as long as you are using a horizontal turbine. With a vertical, or savonius, the diameter means nothing, because the area can be changed dramatically with a taller or shorter barrel. It is the area of the rotor that the wind sees that must be used for power calculations. Once Mr. Voneschen finishes his discussion, showing a diagram of a horizontal turbine, he then goes on to show you how to build a vertical one, so the hybrid formula no longer applies.

The other problem is the efficiency he is using. The best modern turbines that science can build today run in the 25 to 35 % efficiency range, and they are all horizontal. Albert Betz correctly calculated that the best ideal efficiency any turbine could ever reach is a theoretical limit of 59%. The horizontal types have horrible efficiencies, generally in the 5 to 8 % range. The reason for this is that most of the torque developed by the downwind blade is used to push the upwind blade back into positon, so very little is left to actually push the generator. It is this reason that no commercial applications of these devices are built today. I think Savonius rotors are neat, as do most of creation, but besides turning a wind chime in the garden, or running a small pond pump, they can’t really do anything for us. In Mr. Voneschen’s instructions, he is using 50% as the “rough” efficiency of the home made barrel rotor. Even the very best horizontal units today do not come close to this level of efficiency, a good quality well engineered savonius rotor won’t be within one tenth of this level.

We’ve been powering our home for 11 years now with the wind and sun, and the last 5 years or so I’ve been teaching renewable energy seminars in the local schools. In my experience, there are two things in vast supply when you get into wind power, wind, and missinformation. My suggestion is to go to the source and don’t waste your time asking questions to hacks like me online. When your turbine is finished, if you can get it to run well in a wind tunnel, get some good watt readings, then go to the American Wind Energy Associations website and do your calculations for theoretical power available, and it will be simple math to come up with your efficiency. Don’t be dissapointed by the results, if you can reach 3 or 4 %, you’re doing really well. Take care Drew, Rudydoo

Has anyone made a home made generator?

Has anyone made a home made generator? I am looking to make a small solar, gas, battery powered generator, something that will run some barn lights. If you have made one, please give me a list of parts, and instructions. maybe a good website to visit.

Windmill Farms answers:

How To Build A Wind Generator ———————-Build a generator from a lawn-edger motor.—————-Homemade generator—————————- home made generator Once I bought a petrol engine of an old lawnmower on Ibazar (now Ebay) because I wanted to learn how a four-stroke engine worked. I took it apart, cleaned everything, placed new seals and finally mounted everything back together. But she would not start. After having taken my tools again and having put it together a second time, around two weeks later, she gave her old sound again. It was the first time I saw her spinning, and she did great!

Having done all this, I thought, why should I not build something useful with this piece of beautiful equipment? At first, I had the idea of making a powerful water pump with her, but because I could not find suitable parts, I changed my mind and decided to build an homemade electric generator.

For making my electric generator, I started with the engine that I already had. It is a Briggs & Stratton 3.5 HP with a vertical shaft of 7/8 inch (22.22 mm) diameter. Serial number: Model 92908 Type 1282 – 01 Code 82021605 (engine is from 1982!) ——————-I made a homemade generator. Clip this post email this post what is this?

Posted by mihi Southeast (My Page) on Wed, Oct 18, 06 at 22:45

I recently built a homemade generator. I decided it would be nice to have if we lose power and I want to keep the refrigerator and freezer going.
Here is how I did it:

1) I asked around and got an old lawnmower given to me. It was a Murray with a 4.5 horse Briggs engine. The handle was shot, the wheels were falling off, but I got the engine running good. I cleaned the air filter, which I don’t think had ever been done, and changed the oil and sparkplug. It runs fine now.

2) I bought a steel plate for $25 from This plat has universal holes drilled for a lawnmower. It also has the mounting holes for the alternator I would need. I bolted the lawnmower engine to the plate. I took the blade off the lawnmower first though. I also used 3 washers between the plate and engine to lift it off the plate a bit. This was needed to insure it could get in “depth” alignment with the alternator, in other words so the shaft didn’t stick down to far.

Also, the blade acts as fly-wheel weight, which you lose when you take it off. I’ve found the pulley and alternator bring enough weight to make it work OK though and start easy enough.

3) I put a pulley on the lawnmower crankshaft. This to run the belt that goes to the alternator. I also got this pulley from epicenter. Theirs is a very good quality one, better than what I saw at Northern Tool.

4) I picked up a GM alternator. You can get the model number needed at theepicenter to from some of the plans they have. I used the alternator where you have a switch in the circuitry so that you can switch on the alternator to charge the battery, or you can switch it off. You can pick-up used alternators at the car junkyard, about $25. Or you can get a newly rebuilt one for about $50 or so. You do need to understand the different types and how they hook-up, which is really very simple. Theepicenter website gives a good description.

5) You have to bolt the alternator to the steel plate. I had to go to the hardware store to get the correct bolts and stuff for this. It was easily done though.

6) You have to get a belt to run between the engine pulley and the alternator pulley. I ended up getting one from theepicenter too, as it was about as cheap as anywhere else and I got the right belt. Read their info. To decide on the right belt to use. I put the belt on and tensioned it just by feel.

7) I had gotten some cables that would work to hook the alternator to the battery post of a 12V car battery that I had available to me. Tell the guys at the autopart store what you’re doing, they have them. You can also get them from theepicenter too. In this system you have to have a battery because a car alternator needs to be attached to one when it is charging. But that’s OK, I like having the battery because I can run small appliances without having to crank-up the engine.

8) Then I ran some wires and a couple of switches, which I got at the local auto parts store, to an inverter that I had ordered. I got a 1200 watt continuous inverter for $99 (and no shipping charge or tax!). You can get small 400 watt inverters for about $25 if you only need to power small stuff.

9) I didn’t mentioned that I built a wooden frame for this all to set on. Its a hodgepodge of 2×4′s I had laying around. But it does the job of holding the steel plate with engine and alternator, and battery

Maria asks…

What do you think of this Wind Turbine idea?

Please view the youtube video.

I made a model of the Wind Turbine and how it works. Im just wondering if you think its a good idea, bad idea, will it work, will it be effective if not why?

The blades are suppose to generate lift and help keep the wind turbine spinning and keep its momentum up so it keeps a generating power at a high and steady rate.


Just comment here or on the YouTube video its self!

This is a relationship question!

Relationship with wind and turbines……

Windmill Farms answers:

Hey Alex, forget about Robs answer below. Lots of people are always weighing with answers about renewable energy technology, without ever having laid a hand on a wind turbine, solar panel or biomass generator. Our home has been powered by the wind and sun for 11 years now. Our turbine is a conventional horizontal unit, 3 blades, a little bigger than a ceiling fan, yet when the wind blows, it completely powers the house and has a little left over to charge the batteries.

The turbine in the video is commonly referred to as a VAWT, or Vertical Axis Wind Turbine, but the correct name is Darrieus Rotor, named after the engineer that invented it. Darrieus rotors are notoriously inefficient, generally converting around 5 to 8 % of the winds energy to usable torque. The primary reason for this is most of the energy captured by the downwind blade is used forcing the upwind blade back into position for the next cycle, so very little is left to do any work. In the case of the video, the designer has decided to use some of that tiny amount of torque to propel additional blades around to force air downward, which means even less will be left to generate electricity, or do anything else. I suppose if you were trying to use the energy of the wind to operate a ceiling fan this would work fine, but it would be easier and cheaper to simply construct a sail that diverts the wind downward without the use of any moving parts.

We’ve been teaching wind and solar power seminars at the local schools for several years, and despite the science involved in wind energy, I am constantly bombarded by people that think VAWTs are really neat. It takes in inordinate amount of time to convince them what the power companies have already figured out. That is why all the wind farms you see being erected today use horizontal turbines, they actually make a lot more useable power for the same amount of money. A vertical turbine might be handy for pumping water in a pond, or running some garden lighting, but you’ll never get a washing machine to run on one, we’ve proven that already. If you’re really curious about this, my suggestion is to check into the sources below, and maybe do some of your own research, instead of asking hacks like me online for advice. In my experience in renewable energy, I’ve found three things that exist in abundance, wind, sun, and missinformation. Good luck Alex, and take care , Rudydoo

Windmill Farms answers:

Useful suggestions for getting others together to work toward a brighter/greener future:

Getting friends, neighbors, others that you trust, etc together to vote against environmental destruction and you may be surprised in what a group of people can do, once they have their hearts and minds set on something. Then having all of you spread the word even to people in higher places so that may be able to greatly help out as well (After all most people deep down inside, care about this world and want to help secure a beautiful world for us all and all future generations). Perhaps in spreading the word some one may be found that is high enough (With enough power) that could even help you to create advertisements in the news-paper, create pamphlets to staple on posts, phoning others, through the net, or maybe even advertising on a local TV/Radio station, etc.

Even creating a project/speech may help out by letting others know what your cause truly means to you, and why it should be addressed. I am sure that you will be able to find a lot of people who will be willing to help you out in this and other future events. Just remember to stand up for what you believe in and even if worse comes to worse then you and others can still have the power to prevent other unwanted events from happening in the future since their are tons of people out their who care and will be willing to help in situations like yours as well as many other events/situations. Just keep a record/info of all your contacts so that if anything else comes up, you will be able to have several people by your side in no time at all!! Again, best of luck and I hope that everything goes well.

For hot weather, I would also recommend buying a few large oscillating fans and only turning them on when you are in that area of your house.

You will find that the air will become cool and refreshing within virtually no time at all and that their will be a nice refreshing breeze.

With this in mind there is no need to leave them on in any areas of your house where no one is present and you will find noticeable money savings and it will also aid the environment.

Also, if businesses could have even some solar panels (Seen some great lightweight/highly flexible ones on the discovery channel years ago that are cost efficient, easy to install and collects a healthy amount of sunlight/energy). There is Lots of empty roof and wall space not just for businesses but several other structures and buildings as well that can have these special solar panels) it would help in reducing energy needs as well as placing solar panels in open unused areas (Wind turbines as well). There are also several areas on the globe such as deserts (In areas where they would not get damaged), and so on where tons of solar panels can be placed and several areas with high winds for wind turbines.

There are also many unused and open areas where trees, shrubs, bushes, etc could be planted and it could also be a good idea to introduce points system to cities known as “Green Points” where points are awarded to those who do helpful tasks for the environment and even having more greenery in there back and front yards. Along with schools and businesses, etc having a healthy amount of plants in there rooms, offices, etc. Having more environmentally friendly products, etc and the people who reach and exceed a certain amount of “Green Points” each month will get a reward of some sorts that will make it worth there while.

Water Conservations, Oceans, Etc: (Click on “Inch of rain” for picture info) (Click on “100 Ways to Save Water” for great info)

Get other involved in Recycling Goods/Items+Green Living:

Easily help the environment for free:

I also have lots of info that I think you will find quite helpful and enlightening: for excellent inspirational info within my blog to help not only our world and its creatures, but to also open peoples hearts and minds to many amazing wonders that life has to offer. I also have lots of info in my blog to help fuel peoples imaginations to many possibilities that can be found only in the minds eye.

Along with lots of environmental info, amazing environmental pictures and videos (These videos show the beauty of this world and what life can be like if people take the time to appreciate life’s true beauty).

Let us all strive for a greener/brighter future by helping to create a solid foundation for future generations to build upon, so we can hand them a beautiful world, filled with never ending awe and wonders!!

Where peoples differences and uniqueness are accepted, where we all live as one, helping one another so that we can all play our own mysteriously beautiful melodies in the never ending, awe inspiring, song of life :-)

I truly have faith in humanity and believe that someday our lives and the world in which we live will truly be transformed for the better.

Joseph asks…

alternative energy research paper?

so my english class has to write a 15 page research paper and we’re working on picking topics. My first thought was to write it about alternative energy (green energy, other fuel sources, etc.). the thing is that i have to argue something in the paper but i dont know what i could argue about this topic. any input on this topic is greatly appreciated thanks!

Windmill Farms answers:

Yep I just did a shorter version on the same topic not too long ago. The way I did it was to look at the energy savings and environment versus cost. Lets say you want to put up a wind turbine to energize your house. Now that will set you back around 80K. It will last you around fifteen years minus what it costs for repairs and maintenance. Now if you were just hooked up to the grid, your monthly electric bill is say 100 a month, 1200 annually, in 20 years it would cost you 24K. There is wind, solar, geothermal and others but the other caveat is manufacturing. To build a transformer, wind turbines, geothermal piping, pumps they still have to be built somewhere as in a factory that is tied to the grid, coal plants, nuclear power plants and so on so where is the environmental savings? The one thing I could do was look ahead to the future but not in five or ten years but maybe your kids, kids, kids, and a hundred years from now, not two years before the next politician can get himself elected blabbing about it. So basically I took a stand point of yes, it is good (and yes I do agree that we need to do something different) but for right now it is more expensive for us to put that out on the market like you would buy a loaf of bread than to stick with what we have until more viable “cost effective” solutions are found. By the way they have been doing wind turbines in California since the 80′ and what? They still have nuclear and coal plants? :) So it is going to take a lot of time and my argument that was a hundred years from now like I said earlier. So I think if you might want to take the stance of yes, it is a good thing and yes there are many sources available and you can find resources for quite a few they are working on right now but cost effectiveness is currently not there but still we need to look far into the future and maybe not so much in our lifetimes that we will or even can rid ourselves of dependency on natural resources such as oil, gas, etc. I’ll throw in the “conclusion” of my paper so you can get an idea of the azimuth I took on it to give you an idea and maybe you can use it or not but in either case hope it helps.

I stuck with Solar, Wind and Geothermal for this paper:

Alternative energy sources being developed today are still in the stages of being more than a hefty goal to rid ourselves of fossil fuels and nuclear sources of energy. While all three have distinct advantages in that many are technically “free, renewable, and to many degrees sustainable,” each have their associated “Achilles heels” in regard to startup, manufacturing and installation costs and even more so when considering the added future cost of maintaining the systems, early replacement of major components and in the case of geothermal energy sources, the high possibility that the area used can “dry up” in less than a year or last for decades. As a long term goal, finding cost effective and viable alternative energy sources is a must when thinking eons ahead of our own lifetimes while the major factor to overcome is the current monetary costs and what can be manufactured as a replacement for individual consumers or at the very least, spread the higher cost of installation and maintenance and usage as a lower effective cost across a larger spectrum of a community or population while decreasing and eliminating our dependency on fossil fuels as our main energy source.

Doing a school report on comparing and contacting companies that are going green and that are not going green. Also does anyone know a couple of good website that are all about small business going green?

Windmill Farms answers:

This whole “gree” thing is just a fancy word for being more efficient. It’s just a buzz word most of the time unless the company is really doing something like putting up wind mills to generate power. Any type of typical business saving like getting rid of paper pay check are touted as “green” but are really just was for the company to save money and look like good guys at the same time.

But…. I’m glad I didn’t invest in a turbine.

When I pressed the vendor if he could stand by his claims for the power generation, he went all furtive and withdrew his original offer.

He said I’d get my money back and even be able to sell electricity BACK to the utility companies. Sounds brilliant.

But he couldn’t give me a single example of anyone that does this.

In the past, I’ve bought a couple of solar panels, and neither of them worked.

I do use a wind up radio though.

Can anyone help me? I want a real example of power generation. What’s the average power generated by a wind turbine? (I want the real figures, not the idealistic figures)

I looked a Hugh Fearnley-Whittingstall’s river cottage web site, which publishes daily figures for power generation, and the figures don’t look too impressive.

I want to build a machine that translates my physical exertions into useful energy. For example. If I could row for an hour, I might be able to turn a drum and get my laundry done.

Or cycle on a stationary bike and use that energy to turn a turbine or grind up all the packaging from my dustbin.

Where do I start looking for equipment?


Windmill Farms answers:

Where are you going to put the turbine?
How much wind is there?
For how many hours each day?
During which seasons of the year?
Or were you expecting someone else to know all this?

Where would you mount the turbine?
Are there any trees nearby?
Does your house block any of the wind?

Wind is always stronger higher up.
How high were you going to put it?
Does your town allow you to do that?

As for generating electricity with a stationary bike, it’s not worth it.
Consider, Tour de France riders, who are some of the most fit people in the world, generate something like 300 watts when they’re really pushing.
You’d be lucky to get a 100 watt bulb to it’s intended brightness.
And none of your appliances are going to run on just 100 watts.
Your paper shredder will use more than 100 watts.

It is quite reasonable to ask for some kind of guarantee.
It may be, however, that it’s just not going to work where you live.

Also, if you put up “a couple of solar panels” what were you expecting them to do?
Solar panels create DC, not AC.
I seriously doubt that you have many DC appliances, or applications.

OH, and wind turbines don’t automatically make 60 cycle AC.
It takes considerable electronics to make that happen.
Expensive electronics.
And, your utility will have very strict rules concerning you feeding current back into their grid.
Did you look them up?
Did you buy, or look at, the equipment that they will require you to install for that to happen?
I’m just guessing here, but i suspect that you have considerable work to do before you should consider investing the several thousand dollars that is required to generate grid compatible electricity.
