Wind Power Energy

John asks…

Is their enough wind to power the Philippines?

the Philippines has the potential to generate 70,000 megawatt of electricity from wind power. what is the total energy consumption of the Philippines? will 70,000 megawatt be enough to supply a large percentage of electricity for all of the Philippines?
nobody read or answered the question.

Windmill Farms answers:

There is no continuous winds that have the potential to sustain a profitable wind power operation. But there is one way and that is to harness powerful winds blown out by seasonal typhoons. Unfortunately, they are very destructive and limited only during the rainy seasons. So for the rest of the year, the expensive turbines and generations would only rather be a huge liabilty. Also, dams will have more than enough water to operate hydropower plants. So in one way or another, there will be excess production that will most likely not be used so they should be stored for future demand. And storing of produced electric power is costly if not unfeasible to the Philippines.

Sandy asks…

What should I put in a wind energy Powerpoint?

I am doing a Powerpoint presentation on Wind energy. What are some good topics to include?

Windmill Farms answers:

Put advantages and disadvantages.
How often is it windy enough to use turbines? At what speed is it too much?
Show calulations about output vs length of blade ( it’s the square of the length)
Appearance compared to other power plants
Compare environmental issues with Nuclear power plants / gas-fired plants etc
Generation costs
Longevity of the turbine (30 yrs)

Richard asks…

what is the price of wind energy compared to the price of fossil fuels?

when i say price of wind energy, I’m talking about wind mills or whatever transforms wind energy into another kind of energy.
I also need comparison

Wind Mill price = $??? > or < than fossil fuels

Windmill Farms answers:

1 kWh of wind power = $0.17
1 kWh of plant powered by natural gas = $0.04

Nancy asks…

How many fossil fuels does Wisconsin use up in a day?

I am doing a science project on which is the best renewable future energy source for Wisconsin. Either solar energy, wind power, or methane gas. I need to know percentages of energy used up by the state, the number of fossil fuels being used up compared to all other states, and I need to know Wisconsin’s total sunlight and wind (mph) amount in a year. I need links to websites. So can you please help me?

Windmill Farms answers:

The EIA (U.S. Energy Information Administration) collects, analyzes, and disseminates independent and impartial energy information.
NERL (National Renewable Energy Laboratory) is the facility of the U.S. Department of Energy (DOE) for renewable energy and energy efficiency research, development and deployment.

The first link below is about Wisconsin.
There are separate sections for energy production and energy consumption.

Mandy asks…

How to apply solar and wind power for agriculture?

Please describe me how solar and wind power is utilized for farm production and animal husbandry in developing countries.

Windmill Farms answers:

Take a look online for solar or wind agricultural products, and if you live in a rural area, look around and you will see applications some old and some modern.Aeromotor wind pumps have been used for many many years to pump water in remote locations. Did you ever hear stories about the windmills in Holland? They have been used for grinding grains, as well as pumping water, and in San Fransisco Golden Gate park, the big windmills at the western edge pump water for irrigation of the park plants.Many are still working today!
Solar powered water pumping is done.
Solar powered fence chargers for electric fencing are available, as well as solar powered yard or shed lights.
Gate openers are available for use with solar power. Take a look at some of the agencies that promote alternative energy for use in developing countries and see what is out there. Electricity gets used for refrigeration, although there are solar powered refrigeration units that use no electricity, but rather a system for cycling of ammonia for cooling.

Is Wind Power Really Green

Linda asks…

What are the advantages and disadvantages of using solar power to generate electricity?

and hydroelectric, geothermal and wind turbines..
lol @ went to school

Windmill Farms answers:

Solar power, hydroelectric, geothermal, and wind energy are very clean and and equally important renewable source of energy.

The advantages are the green factor and renewable sources. Also I believe that a shift toward these types of energy sources Solar in particular will lead to power systems becoming more distributed. I won’t go so far as to say that that is an actual advantage but many would . It has a whole set of problems and rewards in of its self.

The disadvantage would be unreliability. This will change much as newer methods are adopted as standard power production methods.

While some would say they are an eye sore I would say no more than any other type energy plant.

At present oil/coal/wood is easy to get at, abundant, and the world is driven by it. There will be a slow shift towards other types of power as they become cheaper and more reliable. You can bet when there are other cheaper forms of energy that are as reliable as current systems they will usurp current power production methods.

Steven asks…

What is the most efficient type of power plant?

And why?
sorry i meant “POWER STATION”

Windmill Farms answers:

Wind power. Though it takes up a lot of land it is the most cost-effective, green, quick to build source of power. And, because it is cheap if more companies/ if you started doing it, it’d be cheaper than normal electricity.

Betty asks…

Can Wind Power be described as a sustainable energy source? Give reasons(using Dover* Windfarms as an example)?


Windmill Farms answers:

The word ‘sustainable’ may go down to semantics. Energy sustainability and security of supply are twin concepts in energy investment.

If you want to liken sustainability to availability, from the supply point of view, wind power may be green friendly, but do not have an extensive radius coverage to very distant end-users. Hence, in relation to the sunk cost investment wind farms will gulp in comparison with its energy supply capacity, its not an economic attraction, and so, not a sustainable source of energy on economic grounds. But if you want to narrow sustainability to renewability, a windy region will never run out of wind. So, in that sense, as far as there is wind, there will be power. It’s sustainable!

But down to the wires, putting the Dover Windfarms in perspective, which is situated between East Langdon and Pineham to the north of Dover, these are close to residential regions, and a third factor also comes to focus in ascertaining its sustainability. Wind farms close to residences are usually barricaded for the reason that they could distort views, or even lower the value of property in the area. Hence, they are usually welcomed with public disapproval. In this sense, it may be UNsustainable on social grounds. On political grounds, its a whitewash for scoring political points without political will (revisit the economic grounds)

However, although the Dover Windfarms passed the environmental risk assessment test as fluvial, tidal and groundwater floods with a PPS25 Flood Zone 1 – Low Probability level, as well as a topography with high elevation of 95, above Ordinance Datum, and a minimum elevation of
75m AOD, this particular windfarm may have passed the environmental test to inspire sustainability. But that’s just one wind farm. This assessment is not of general application. Again, that’s not it passing the human or economic test.

Helen asks…

How do humans affect wind – wind turbines ?

So i have a few questions.
1. How do we human affect wind
or wind turbine power?

what can we do to make sure its sustainability?

thank you very much

Windmill Farms answers:

The current generation of students and their politically correct teachers seem to believe that wind power is the solution to all of civilization’s energy needs. Nothing could be further from the truth. In fact, because of the way it works, wind power creates a need for higher carbon emissions than are necessary….

Wind is inefficient and expensive.

Since wind turbines were installed in Denmark the Danish grid used 50% more coal-generated electricity in 2006 than in 2005 to cover wind’s failings.

According to the Copenhagen newspaper Politiken, “The increase in the demand for coal, needed to plug the gap left by underperforming wind farms, meant that Danish carbon emissions rose by 36% in 2006. This has undermined the ‘green’ credentials of Danish wind farms. Meanwhile Danish electricity costs are the highest in Europe. The Danish experience suggests wind energy is expensive, inefficient and not even particularly green.” Danish Member of Parliament Aase Madsen who chairs energy policy admits: “For our industry it has been a terribly expensive disaster”.

Der Spiegel recently reported that despite all the wind turbines in Germany (more than 20,000) “German CO2 emissions haven’t been reduced by even a single gram” and even the Green Party has recognized the problem.

The German electricity supplier E.ON Netz Wind Report (2005) warned: “Wind energy is only able to replace traditional power stations to a limited extent. Their dependence on the prevailing wind conditions means that wind power has a limited load factor even when technically available.

“It is not possible to guarantee its use for the continual cover of electricity consumption. Consequently, traditional power stations with capacities equal to 90% of the installed wind power capacity must be permanently online in order to guarantee power supply at all times”.

The Wall Street Journal explained last September that in order to cover the inconsistencies of the wind power now on the German grid, “Germany’s gas consumption for power generation more than doubled between 1990 and 2007.”

In the U.K., the newly installed wind technology is also backed up by gas. Figures released in November by the OECD indicate that “in the past year alone, prices for electricity and natural gas in the U.K. Have risen twice as fast as the European Union average”. This is good news if you are in the gas distribution business.

In Ontario, Canada, where the government is pursuing the wind power folly, it is estimated it will cost 5 billion dollars for new transmission lines to send wind power to the province’s cities. This will add 30% to every Ontario electricity bill. And that doesn’t cover building and supplying the gas plants to cover wind’s intermittency.

The claim that wind energy provides thousands of jobs is also contradicted by European experience.

In Spain, with 15,000 MW of wind power already operating, each new job in the wind industry has cost taxpayers one million Euros in subsidies and few of these jobs are permanent.

In Spain electricity rates had gone up 30% in two years by 2007, not to mention an increase of 85% in the price of natural gas.

And there has been a huge exit of manufacturing industries that depend on high electricity use. Many of these multinationals have moved out because they found lower electricity rates in other countries. Spain’s unemployment rate is now 14%.

How’s that for a few disadvantages. And, I haven’t even included the arguments of the NIMBY’s who don’t like the sight or sound of wind in their neighbourhoods. Or the new movement that is fighting turbines based on health issues.

John asks…

If Green Energy is so great how could this happen?

Windmill Farms answers:

Where I live there is a wind farm about 10 miles long. Two people work there. Just a couple questions for green energy. How much more expensive is an engine that will burn E85 (85% ethanol, 15% gasoline) ethanol. Well it looks something like an NHRA fuel class engine or something comparable to a NASCAR engine. Check out the price of those engines. This is only necessary because a gallon of ethanol produces 66% of the power gasoline does. How much electricity does a solar farm produce at night? How much electricity does a wind farm produce in calm air? A major factor to consider with green energy is that if it were financially practical capitalists would be all over it. Our president ignores this.

Charles asks…

which one is the good stock market Green energy ethonal or uranium power or neuclear power?

I need to find out growing market for investment in stock market.

Windmill Farms answers:

Just my opinion, and yes I have/do own some of these:
Ethanol is too up and down for me. Was in Pacific Ethanol.
Uranium is good
Thin film solar like FSLR is good
Wind blades like Vesta wind in Germany is also good.
You might also look into some more traditional companies like GE
Read through Wikipedia for newer technologies coming forward like using algae for scrubbing the exhaust from coal plants. Or the new ocean swell generators being tested in Europe.
These are story stocks. Story stocks skyrocket while the story is hot. Let it get cold and everyone will run for the door. You had better know how to use Stops.

John asks…

can someone reccomend me some stock investing books for begginers?

Windmill Farms answers:

Invest in A-Power Energy Generation System (APWR) stock is a great place to invest because the stock it blow 200 day average so in the short term(1month-1year) it will increase really fast when it in the market earning short_term (1month-1year) you will earn 1-2 time the amount that you put in which in and of you put in a long-term you return it will be 15-20 time which it 5-10 years. The company is the biggest owner of wind turbine in china and the company is expending to other area such as U.S, Europe, and many more countries. The companies is expend their wind turbine to many different area the stock average return a year is about 20% but with right now the we are on the way to getting out of recession the average return is about 50%-120% a year.

How can i multiply my $100 into more?

Im 17 and im getting ready to graduate high school and i want to start to be smarter with my money and hopes of making alot in the future i feel that this skills will be beneficial.I have 100 dollars and hopefully soon to be $250 at the least and i would like to know how i can multiply it at a constantly rate, maybe investing it in something that has a reasonable profit.Any suggestions!

Windmill Farms answers:

Invest it in wind energy stocks.

Think about what’s going on in the world right now. The entire middle east is throwing over regimes that have ruled for centuries. This nations oils supply is in a dubious position, and we want to break our dependence on oil anyway, because scientists across the globe are convinced about the phenomenon of global warming. That means that our government will likely funnel billions of dollars into renewable energy in the near future, and wind stocks will skyrocket in value.

I’m telling you, invest in wind energy, and wait a decade. Your $100 will turn into your retirement fund.

Renewable Energy Group

Mary asks…

an electrical engineering can work on renewable energy?

I want to know if electrical engineering is the right choose to work on renewable energy like bio-diesel.biomass or hybrid technology also I want to know if an electrical engineer could lose his job when he become older for instance computer science company hired younger people is the same with electrical careers? thanks

Windmill Farms answers:

An engineering background would be quite useful for renewable energies, quite useful for most things in general. Most engineering programs have a general engineering requirement where the students spend one to two years studying all the engineering fields before specializing so an electrical engineer would have sufficient chemical and mechanical engineering background to be useful in bio-diesel and biomass as well as be suited for the electronic controls inherent in all modern processes. Naturally, a hybrid would have a large electrical component that the EE would be useful for.

It’s illegal for a company to age discriminate but it is true that as one gets older and better paid, one’s liquidity on the labour market is reduced. However, many companies value experience and for good reason. Without some experience in a group, one’s bound to constantly repeat the same mistakes over and over again.

The risk of loosing one’s job and then finding it difficult to be re-employed is common no matter what the field and often if a company wants to take a risk on a prospective employee that they have not worked with before, they might as well hedge their bet by hiring somebody inexpensive such as a fresh grad.

You can take measures to ensure you remain valuable in the job market, insist that the company pay for at least one professional association membership and at least one industry conference a year. Attend the tutorial sessions and pay the extra $10 for the CEU credits so that you have something to add to your portfolio.

Above all, build up a network of contacts in the industry. It all boils down to relationships and people.

You might want to start with an English course though.

Michael asks…

renewable energy, company’s to invest in?

Windmill Farms answers:

With individual stock investing, green or renewable stocks do not have their own industry group, but are sprinkled in amongst non-green or non-sustainable oriented companies. So you have to go another route in first identifying which companies are green investments and then secondly, determining if they are a “good buy” substantiated by good fundamentals and technicals (a positively trending price).

I found an awesome website called Sustainable Business that has a “Green Stock Watch” list by category. And even more interestingly, a list of what they call the World’s Top Sustainable Business Stocks or the SB20 for the last three years. They also clearly state that the stocks are chosen based on innovations and financials, but that they may not be in a buying position today. I’m so glad they said that.

Which brings me to my second point, because even if the financials are sound you should always check the company stock’s price chart. I would not advise purchasing a stock that is trending downward. Generally, look for a stock that’s price is trending upward, wait for it to pullback and then look for a renewed upward movement with some higher volume.

The good news is that as our culture absorbs socially responsible practices, that generates increased company earnings which in turn, creates healthy stock prices and attractive stock picks. Pretty great stuff.

Betty asks…

tell about renewable and non renewable sources?

uses of both

Windmill Farms answers:

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups — renewable (an energy source that can be replenished in a short period of time) and nonrenewable (an energy source that we are using up and cannot recreate in a short period of time). Renewable and nonrenewable energy sources can be used to produce secondary energy sources including electricity and hydrogen.

Renewable energy sources include solar energy, which comes from the sun and can be turned into electricity and heat. Wind, geothermal energy from inside the earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels — oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains (or “fossils”) of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity. These energy sources are considered nonrenewable because they can not be replenished (made again) in a short period of time. Renewable energy sources can be replenished naturally in a short period of time.

Thomas asks…

what are renewable energy batteries?

I basically want to know the difference between normal batteries and renewable energy batteries.please do help me in finding some more detail regarding renewable energy batteries.

Windmill Farms answers:

Hey Apoorva, you’ve stumbled onto sort of a nonsense term. Allan is quite right, in that batteries are considered primary or secondary, depending on whether they can be recharged and reused again. These terms are used in battery engineering circles, you won’t find someone at the store that understands them. Keni is also correct, a renewable energy battery can only really be called that if it is charged with a renewable energy source. The term, “Renewable Energy Battery,” is a marketing term, it doesn’t mean anything to an engineer. With all the hype today on renewable energy, battery companies have been trying to cash in by throwing terms like this around in their literature and on their websites. Try googling, “Renewable Energy Battery,” you’ll find yourself at battery manufacturer websites like Surette, Trojan, Exide and some others.

The only thing that makes all these batteries common mechanically is that they are true, “Deep Cycle,” batteries. Thirty years ago, batteries that went into cars, trucks, and even buildings were all basically the same, they had thick lead plates immersed in an acid bath. When you took power out, the acid split from the water in the bath and combined with the lead, making a different lead alloy and releasing electrons in the process. When you forced power back into them, the acid was forced out of the lead and back into the liquid. As mileage became important in the 70′s, new lighter weight batteries were needed, and the, “Cranking Battery,” was born. It uses the same chemical properties, but the lead plates are porous, much like a sponge, allowing more surface area between the acid and lead with less weight. This allowed a small battery to put out hundreds of amps for a few seconds, plenty to start the car, then it rode around all day being recharged with nothing better to do. They don’t hold up as well as deep cycle batteries, and can’t withstand deep discharging on a frequent basis, but that doesn’t matter in a car.

Renewable Energy systems don’t need high output capabilities, but they need to withstand thousands of discharge cycles, so they use the old type battery, the thick solid lead plates with plenty of acid bath. They are bigger, more expensive and harder to ship around because of the size and weight, so you pay more for them. The truth is, there are plenty of good batteries out there that can be used for renewable energy storage, my personal favorite is the golf cart battery. It’s designed to be drained once each day, slowly, then recharged each night. Turns out they work great in a solar home, where they charge all day, and drain all night. So many of the battery companies are eager to claim their products are, “Renewable Energy Products,” even if they are really just deep cycle batteries.

Our home has been powered by the wind and sun for almost 10 years now, and the batteries are nothing more than overgrown golf cart batteries. They are called L-16′s, made by Trojan. Their popular T-105 golf cart battery has the exact same structure inside, except the L-16 is 16 inches tall, hence the name. If you trying to learn more about renewable energy, there are some great non profit groups you can get information from, and one magazine as well, Home Power Magazine. It’s the only periodical that gets into the nuts and bolts of growing your own electrons. I will list their address and some other links below. You might also look for Richard Perez’s book at the library, you won’t find a better explanation of batteries in the world. Good luck, and take care…Rudydoo

Mandy asks…

Help with renewable energy resources in France?

I’ve been set a task to find out about renewable energy in France. What do they use most, how long have they been using it for? Stuff like that. Thanks! :-)

Windmill Farms answers:

Use different search engines and different search criteria, each engine has a different algorythm that will produce more of fewer results.

France does use about 75 to 80 percent nuclear power to produce electricity. This has been a statistic that some pro nuclear groups use to try support how safe it is- but no mention of the protests and riots over the waste storage. When was the last time you heard about the fiasco over Germany’s own plans for nuclear waste disposal? And they have a vocal opposition to it as well, and you virtually never hear of it.

I am opposed to nuclear energy myself, Chernobyl saw to that. But short of a failure of equipment on that scale, the US “news media” is heavily filtered and censored, you would never hear of the smaller accidents that happen. And that is what the Pro-nuclear lobby groups are trying to capitalize on. It has been about a generation since that accident, so what else can we expect?

You might get some additional information indirectly, refocus on EU and European Union, those statistics might be more readily found, and would be broken down by member country. Also search the UN website as they sometimes collect that data. Http://

Wind Power Facts

Maria asks…

How is it possible that Japan, being seismic, has 55 nuclear power plants? Is this the last straw?

Why don’t all countries swtich off their nuclear power plants and start using other forms of energy?

This is the limit!

Windmill Farms answers:

And exactly what ‘other forms of energy’ do you recommend? Oil? Coal?

Solar won’t work because of expense and the fact that Japan has too many cloudy days. Wind won’t work because it is too unreliable.

What do you recommend?

James asks…

As companies develop electric powered vehicles what are President Obamas plans to increase the US powergrid?

President Obama plans to get rid of coal plants that produce a lot of power. Solar and wind powerplants are not enough to handle the increase in demand that will needed to sustain and supply the US with enough power.

Windmill Farms answers:

Obama has been a friend to the coal industry – he has no plans to close coal power plants. Just the opposite, in fact. He has announced a large expansion in coal mining operations (see sources below.)
Generally, there are two reasons that introducing electric cars won’t appreciably affect the level of power demand in the United States.
The first is that electric cars charge overwhelmingly in the evening and at night. Those are off-peak times for power usage, and there’s currently plenty of available capacity (see sources below.)
The second reason is that lots of electricity and other energy is used to refine gasoline. About 6 kilowatt-hours of energy for each gallon refined. This is a lot of energy, and in fact, is nearly the same amount that electric cars use for driving. So if gasoline usage decreases at the same time electric car usage increases, there should be very little overall change in electricity demand (while petroleum usage and pollution eventually slows down to nothing.)

Robert asks…

Renewable energy – wind power How much does wind power cost?

I really have no idea how much windmills cost. I was just curious if there is a site somewhere that has costs to be windmills that are maybe like 500kW, 750kW or 1 megawatt producers of electricity? Does anyone know an approximate price or website with pricing for these?

Windmill Farms answers:

I was working in west Texas last year for several months in the middle of thousands of them. I am an engineer so discussed this a lot with engineers building them.

Seems the average cost was about 2 million for 2 megawatts (Very high compared to conventional / nuclear)just for initial capital cost. They work great. Only take 6-8 MPH wind for them to start generating. The power from them is much higher cost primarily due to the high initial cost and the fact that the wind just doesn’t blow all the time so your investment may sit a lot of the time generating nothing. They also require enormous surface area and a large electrical grid compared to conventional.

I like wind power and Solar power, and think we should build more in deserted areas because even though the power is more expensive, it reduces emissions and reduces our dependence on foreign oil. It cannot provide the huge amount of cheap reliable 24/7 alternative energy we need (Only Nuclear can do that), but it will help.

Ken asks…

can i use an automobile alternator as a turbine in which to produce wind powered electricity?

if so how much power could i expect one alternator to produce?

Windmill Farms answers:

You are mixing up what an alternator and turbine are…turbines and generators/alternators are not the same device…THEY ARE SEPARATE DEVICES. Do not let the fact that they are shaft-coupled fool you.

The turbine is nothing more than a device used to convert energy of a fluid flow stream into mechanical shaft work. There are no electrical parts that are key ingredients to making a turbine work. The turbine is just a set of blades on a shaft with a connection to a fluid stream.

The generator (or alternator)…(thermodynamics isn’t really concerned with the difference)…is the component which converts the shaft’s mechanical work into electrical energy.

So, strictly speaking, you CANNOT “use an automobile alternator as a turbine” because it doesn’t have any blades or whatnot to interact with a fluid.

You need a turbine to act as a turbine. Or maybe a pneumatic cylinder turboexpandor, which is one of the strokes of the automobile by the way.

You can MECHANICALLY COUPLE a turbine with an automobile alternator…but you cannot “use an automobile alternator as a turbine”.

“How much power” could you expect the system to produce depends on the details of your ENERGY SUPPLY. What IS your energy supply?

John asks…

How long would it take to put in an alternative energy grid around our country?

How much would it cost and could you power a national monorail system with it? I think we have to do something to help wean people off of oil. Our government and corporations don’t seem to care. Is it possible to fund something like this through other sorces other than government and how would you do it?

Windmill Farms answers:

I don’t think an alternative energy grid around the country is the answer.

That would simply substitute one huge infrastructure, with all the government regulations and bottlenecks for the one that already exists. It would also require the government to invoke eminent domain in a massive way to the harm of many individuals.

Power grids and their associated infrastructures are very expensive to build. This excuses government in granting monopoly status to them (to justify the expenditure of capital) and, once they are built, there is an enormous inertia that blocks innovation and alternatives.

I think building an alternative energy grid would compound the problem, not resolve it.

I also believe that energy grids, such as the electric power grids, are inherently unstable and too easy a target for terrorists or others to attack and cause disruption of services throughout enormous areas and millions of people.

I think it would be far more preferable to develop a system where, to the extent possible, each household and each building is self-sustaining, through a combination of solar and wind power.

That would leave the power grids to provide back-up. In fact, during non-peak hours, these self-sustaining properties could feed power back into the grid, for which the power companies will have to pay them.

I have not done the research, but I believe the technology should be out there to do this.

I also believe that it won’t be too long before builders who want to have an advantage in the market place, start to incorporate passive and active solar and wind power into the homes they are building. Buyers will pay a higher price for a property that does not consume electricity, but produces its own.

Is Wind Power Green Energy

Richard asks…


I thought if you wanted green energy etc you should vote for the GREEN PARTY…

But the green party is not a popular party, at this moment in time, it’s a minority party..

So why on earth have the colition implented green energy across the UK at the wrong times aswell..

Surely if green energy was SO POPULAR the green party would be in power !!!

It turns out a majority of Brits want nuclear energy..regardless of what happened in japan but they do.

So why have the goverment denied the majority.. and forced this unwanted green energy upon us ?

my bills are SORING and i have tripple A applaiances !!! it makes NO DIFFERANCE.

Windmill Farms answers:

There is more than one policy that people vote for, not just environment and green energy. The Greens might not have any other policies such as for tax, employment, defence, foreign affairs, transport, police, health etc etc or worse still they do (you should read some of the policies the Greens have in other countries, they’re very scary :) As a minority party the Greens know they aren’t going to reach power but in some circumstances can have the deciding vote in parliament if there is no clear winner in an election.

And Japan has been hyped up. Its amazing no one remembers the 20,000 dead from the earthquakle and tsunami but everyone remebers Fukushima Nuclear plant that killed no one.

It is interesting to note that France, being 79% nuclear, has the lowest greenhouse gas emissions per person in Europe (as well as cheapest electricity) and Denmark which is leading the way with wind technology (20% wind) has the highest greenhouse gas emissions per person. Since introducing nuclear power in France the air pollution has been reduced fivefold.

Nuclear power plants helped avoid 90 percent of all carbon emissions averted in the U.S. Energy sector between 1981 and 1994. One coal power station of 1GWe emits about 6 million tons of CO2 per year while nuclear is almost CO2 free (not including indirect CO2 emissions which is comparable to renewables). In the U.S. 104 nuclear reactors annually prevent emissions of 682 million tons of CO2. Worldwide, over 400 power reactors reduce CO2 emissions by 2 billion metric tons a year. Nuclear plants offer a clean alternative to fossil-fuel plants.

Annual waste from one typical reactor could fit in the bed of a standard pickup and the retired fuel from 50 years of U.S. Reactor operation could fit in a single football field; it amounts to 77,000 tons. A large coal-fired plant produces ten times as much solid waste in one day, much of it hazardous to health. We discard 179,000 tons of batteries annually–they contain toxic heavy metals.

Carol asks…

How can I make my own wind turbine?

I am looking to go green. I want to make my own wind turbine. I live in a big city. I own a house and an apartment. I would like to harness the power of the wind and maybe the sun. I have some questions I hope someone could give me answers to.

1. What all would I need to make a wind turbine?

2. Could I make one big enough to go into my back yard or on my roof that would power my 4 bedroom house and maybe charge batteries to power my apartment?

3. What green energy can I install on either residence?

I am tired of paying high electricity bills and with summer coming around I would really like some I am sure everyone would. Any help or advice would be greatly appreciated. Thanks in advance for all educated responses. Much love and peace.

As Kermit said, “It’s not easy being green”. Furthermore, it is rarely cheap and it is often anything but green.

If you are seriously interested in making a green statement and saving money in the long-term, I suggest that you consult professional consulting engineers about the possibility of running your house on “heat pump technology” (described below) and photovoltaic panels.

Once a house or apartment is built, it can be difficult and expensive to make it more energy efficient. About all that you can do is install triple-glazed windows, and insulate the wall cavities and ceiling space with non-toxic but effective insulating materials. You can also replace your old inefficient appliances with more efficient versions. Energy consumption can be reduced by not lighting empty rooms and not heating or cooling empty rooms. In the summer, you can shade the windows so that the sun does not shine on them.

Installing devices like solar hot water systems is an effective ploy but it does take several years to recover the capital cost of installing the system. Furthermore, it is not necessarily very green as a lot of energy is used to manufacture the system.

A very green and effective system is the “heat pump” system. There is a massive amount of heat energy stored in the air of the ceiling space of a house and in the ground around the house as well as in the air around the outside of the house. This heat energy can be used to provide both heating and cooling. Only a small amount of electrical energy is needed to run the fans and pumps. You could use photovoltaic panels or wind turbines to produce this electrical energy but wind turbines are expensive to buy but factory made versions are better and cheaper than are ones that are made at home by unskilled people. Furthermore, many local councils will not permit large wind turbines to be built on residential land because they are an eyesore and are very noisy.

I have known of many people who have converted their houses into energy oases by doing the work themselves but they have been people with a track record of being able to do the work and do it quickly and correctly. Do you have the time, the tools, the knowledge, the skills, the workshop space and the money to quickly convert your house into an energy oasis? If you cannot answer “yes” to all of these questions, you might be best advised to start by doing the simple things like switching-off appliances and lights that are not needed. I saw one house that was converted to an energy efficient one so effectively that energy consumption was reduced by 90% without the occupants have to have cold showers and freeze in the dark after eating raw food — it can be done and thank you for showing an interest in doing it.

William asks…

How can energy be produced?

I know energy cannot be produced just hear me out. :P

All I wish to know is different ways you can provide energy, without using fossil fuels and without creating an emission or something. Preferably avoiding the production of radiation but I guess that problem could be fixed. I’m not sure if any source of energy with the properties I have described exists but I’d like to figure out a way to get past that problem, even though I’m probably not the best person to do it… :P

Windmill Farms answers:

The most “green” energy source: food and muscle power.

Solar energy only makes pollution when the machines are made. Many years before the energy used to make them, is returned as usable power.

Wind energy only makes pollution when the machines are made. A little hard on birds.

Similarly tide energy makes little pollution.

Geothermal pollutes.

Biodiesel only burns what plants have recently collected from the air and ground… So its pollution is presumably net zero.

Hydroelectric ends up being built on fault lines (because that is where rivers run) which causes earthquakes, and they starve the rivers below them (and finally the ocean).

Nuclear makes little pollution, but what it does make we do not process into usable isotopes, so it is intractable.

How do you feel about GOV subsidies for things like farms, businesses and pet projects?

One expensive investment is ALT energy — the money require to set up – plus the higher price of the product EXCEEDS the value ot the product

Is green Energy Co$t effective – after gov subsidies are incl?

NO — often it is not effective.

AN electric car takes hours to charge (electricity costs money) and you get to drive about 30 miles — then it takes hours to charge it again

TO buy a hybrid car cost around $30,000 to $40,000 and you may save a few miles per gallon

SOLAR COST: Based on the lowest current panel prices of $7 a watt, you would be looking at an initial cost of about $77000.


That means a 10 kilowatt machine (the size needed to power an average home) might cost $35,000-$50,000 to set up.

YES IT MAY BE GOV FUNDED OR GOV SUBSIDIZED — just toss that cost on the top BECAUSE
tax payers pay for that out of the taxes
pulled out of their paychecks



Windmill Farms answers:

Fossil fuel is subsidized, too – far more, it turns out. In fact, fossil fuel gets about six times the subsidies that clean energy gets – see article:

Sadly, we live in a world where everything is subsidized – all forms of transportation, airports, railroads, public transportation, petroleum, all live on government subsidies. So no new form of energy or new transportation can compete without getting subsidies, too.
The best solution is for all the subsidies to stop. In such a world, gasoline (which gets about $400 billion in annual government subsidies worldwide) would be a few dollars per gallon more expensive.
Electric and alternative cars would compete much better on this level playing field.

Laura asks…

Is Green Energy and the War on Global Warming proactive or reactive?

Proactive meaning that expensive energy is our future (wind and solar without dams, nuclear, hydrocarbons) or reactive about cheap energy with irrational fear and emotion over the pollution.

Thankfully he is not reaching for quick fixes like the last Bush did or is he?

Windmill Farms answers:

Wind power has been tried in Europe. The result is unsightly wind farms full of turbines that broke down constantly and never really generated much power.

Like the wind farm in California the only serve to slaughter migratory birds.

Of course it would make a lot of money for GE, you know the company that owns MSNBC…Obama’s own propaganda channel.
