How much money would it cost to put solar panels at my school versus the cost of wind power at my school?
You see, I have to do a report on how to make my school more eco-friendly. I decided that they waste the most electricity so I am now trying to decide, which idea (solar panels or wind power) will cost less and save more for my school. I also want to switch the paper towels into hand dryers to cut waste of paper. Back to the solar panel/windpower. I am looking for a few things:
1) which will cost less money?
2) which will be more effective?
3) which will be more green?
4) Is it pratical?
5) pros and cons of each one
Anyway I need this info fast! I will give the 10 points to the person who gives me the best info and the most info the fastest. Thank you!
also, how many of each would i need to cover the electricity of the whole school?
Windmill Farms answers:
YOu can’t give a full answer ot the question without a whole lot more facts. The location of the building will tell you how effective solar panels will be. If it is in the far north, it will not be effective at all because for half the year, the sun is insufficient to power them. Wind power works only where there is consistent wind to run the turbines by turning the fans.
Solar energy has become less expensive because it is now mass produced and is built to be installed in a single facility. Most wind power is gathered in large collectives and the power is distributed through the power company. They are monstrously expensive to build because many of them are in locations that are difficult to get to like out in the ocean or on top of mountains though there are locations on flat land as well in windy areas.
You have to be where the sun shines more than not and where the wind blows more than not or you have to supplement it with purchased power.
I need topic ideas for a term paper about wind energy…any ideas?
I am a second year university student that has to write an 8-10 page paper about wind energy and whether or not it is “green.” However, I am drawing a complete blank about topics I can address in the paper. Any legitimate ideas would be greatly appreciated.

I’ve included some pros and cons for you:
Good Private Potential: People can generate their own electricity with wind power in much the same manner as people do with solar panels (photovoltaics). Some companies specialize in residential installations and there are also several DIY wind power kits on the market. It is possible to save money in the long run with residential wind turbines. Then there’s the feeling of contributing towards fighting global warming on a more personal level.
Residential wind turbines open up for the possibility for people to become completely energy self-sufficient (often in combination with other solar power and geothermal heating and cooling systems). This means that you are not reliant on electricity from the utility grid, which protects you from blackouts and fluctuating energy prices.
Abundant: Although some places are better suited than others, harnessing wind energy can be done almost everywhere. However, whether or not a resource is financially viable, comes down to the following question: “Can we generate cost-competitive electricity with current technology in this particular area?” Offshore wind turbines expand exploitable resources even further, but then potential environmental impact to the ocean habitats need to be explored.
Prices are Decreasing: While still extremely expensive to produce on a large scale, rices have decreased significantly (as much as 60% since the 1980’s according to some sources). Technological advancements and higher demand is expected to continue to push the prices down even further.
Green Energy: Wind energy is a green energy source. Harnessing wind energy does not pollute the environment as fossil fuels, coal and nuclear energy does. Other than construction and installation, generating electricity with wind energy does not involve any emissions of climate gases whatsoever.
Renewable: Wind energy is a renewable source of energy. Wind is naturally occurring and there is no way we can empty the resources (it naturally comes back).
Costs: The cost-competitiveness of wind power is highly debatable. In most cases, projects rely heavily on government incentives to give wind power a fair chance to compete against already well established the power sources such as fossil fuels and coal. Wind generated power ranks second highest only to solar generated power in terms of initial and maintenance costs. Without government subsidies, large scale wind generated energy would be cost-prohibitive.
Noise Pollution: The wind turbines create a lot of noise. This alone is the reason that wind farms are not built near residential areas. People who live nearby often complain of huge noise that comes from wind turbines.
Threat to Wildlife: Due to large scale construction of wind turbines on remote location, it could be a threat to wild life nearby. Few studies have been done by wind turbines to determine the effect of wind turbines on birds and animals and the evidence is clear that animals see wind turbines as a threat to their life. Also, wind turbines require them to be dug deep into the earth which could have negative effect on underground habitats.
Wind Can Never Be Predicted: The main disadvantage of wind energy aside from cost/kwh is that wind can never be predicted. In areas where large amount of wind is needed or winds strength is too low to support wind turbine, there solar or geothermal energy could prove to be great alternatives. That is one of the reasons that most of the companies determine wind turbine layout, power curve, thrust curve, long term wind speed before deploying wind turbines.
Suited To Particular Regions: Wind turbine farms are suited to the coastal regions which receive wind throughout the year. So countries that do not have any coastal or hilly areas may not be able to take any advantage of wind power. The location of a wind power system is crucial, and one should determine the best possible location for wind turbine in order to capture as much wind as possible.
Visual Impact: Though many people believe that wind turbines actually look nice but majority of them disagree. People consider wind turbines to be undesirable to live next to. Petitions usually come before court before any proposed wind farm development.
Hope this helps!
The pro’s and con’s of running your vehicle on vegtable oil??
Do you think it is wrong to run on veg oil and not pay the duty?
Do the environmental benifits outweigh the crime?
Why doesnt the govenment promote green fuels?
Windmill Farms answers:
Since vegetable oil is not taxed as fuel it’s not wrong to use it. The politicians will be sure to tax it eventually and then it will be illegal to use it unless you pay taxes. Take advantage now.
There is no crime in using vegetable oil as fuel. It is environmentally neutral, as the CO2 from burning it is taken out of the air by the plants growing to produce more vegetable oil. There are some minor problems in using it in internal combustion engines [diesels], especially recently built ones.
Using waste cooking oil harms no ones food supply. Those who oppose using fuels made from crops, claiming to worry about competing with food crops are hypocrites. These people really want us to have no energy or to make it so expensive that our civilisation and population will shrink drastically. Their ideal is a totally vegetarian world, farmed by hand labour, using no animals. They propose using renewable and alternative energy sources which are insufficient at this time to replace fossil fuels and they campaign strenuously to end the use of fossils fuels and even fire. They propose extravagantly expensive solar power, but would oppose the huge collectors needed because some desert lizard might be disturbed. They push hydrogen power, which is impractical, but oppose the huge number of electric generating plants needed to make hydrogen. Electric power is made by burning fossil fuels, hydroelectric dams or nuclear plants, all of which they oppose. They oppose wind power because it is unsightly and kills birds. Tidal power plants would be unsightly and endanger some sea creatures.
They would have the great majority of the population die or never be born to protect the “Wilderness”. They call themselves “environmentalists”, but view themselves as the elite who will become the new population of the Earth.
The politicians think first of lining their pockets with money, they get money from Big Oil, Big Auto and Big Labour and green fuels would hurt all those groups. Government gets in the way with its regulations. Underground and earth-sheltered houses are deemed “basements” not eligible for loans although safer and very energy-efficient. Construction has to be “to code” and not better than code. Making your own ethanol for fuel is illegal. Many areas will not allow the digging needed for geothermal cooling and/or heating. Solar panels are not allowed on roofs because they don’t “fit in the appearance of the community”.
These people are also the ones who oppose the genetic engineering of plants, even if only used to make bio-fuels. They moan that growing any type of plant for fuel takes away from the food for the poor. These are the same poor that they want to abort their babies, the poor who are farming and herding and poaching the wilderness into extinction, the wilderness these people want to preserve untouched and unseen by Man. They are the ones who rail against foods tainted by anything, yet oppose irradiation that would eliminate all bacteria and germs from food . The same ones who demand perfect, unblemished produce, yet want to forbid insecticides and fertilisers. I can remember when white eggs got better prices than those “dirty” brown eggs, now those same people pay more for brown eggs thinking they are healthier and more natural. They are all just eggs!
The best alternative is to switch to a type of engine and power system that could use any liquid or gaseous fuel, would be less polluting than internal combustion engines and would be more efficient. They could be in production in 3 yrs and the autos would look no different than IC powered cars and would have as much interior space as any hybrid. E-mail email@example.com and ask about steam-electric hybrids.
Please Help with Green Research!!!!!!?
Ok so for Debate, I need to research this fake bill which states that all american homes need to be 50% energy self sufficient. To do this they need to build solar panels ect. What would be like 5 pros and 5 cons? Thanks so much for everyone who answers!!!!!!
Windmill Farms answers:
Not everyone is out of the woods.
There are many homes that are in the mountains and forest that receive little direct sunlight or sufficient wind to power much of anything.
If they all moved to parts of the country that get a lot of sun then they would also increase their energy use to cool their homes.
Isn’t Nuclear energy a “Green Alternative” to petroleum? ?
Windmill Farms answers:
YES! Nuclear is the most “Green” energy choice for most locations. Here are some Pos 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.
6. No combustion, no Co, CO2 or SO2 released.
7. Creates 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.
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,
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.
Hydro: Only viable in specific locations, dams change the local environment significantly and are dangerous.
Wind: Only a specific range of wind speed is currently efficient for producing power, takes huge amounts of land space, unreliable for base load power – needs a backup anyway.
Solar: Only viable when the sun is out, toxic chemicals in photo-cells and batteries. Takes huge amount of space per Mw.
