Windmills are not as environmentally friendly as you think. While they use wind to produce power, they are not cost effective, especially if you include the fact that windmills kill endangered birds and get waivers for doing so because its green energy.
Got interested in how many birds actually die of windmills in the US. Here's what I found after some searching:
"Wind turbines kill between 214,000 and 368,000 birds annually — a small fraction compared with the estimated 6.8 million fatalities from collisions with cell and radio towers and the 1.4 billion to 3.7 billion deaths from cats, according to the peer-reviewed study by two federal scientists and the environmental consulting firm West Inc.
"We estimate that on an annual basis, less than 0.1% ... of songbird and other small passerine species populations in North America perish from collisions with turbines," says lead author Wallace Erickson of Wyoming-based West." - article in USA Today, smithsonian .com has a similar result
Bad kitty!!! 
Yes they kill non-endangered birds as well, but those on the endangered species list, a list supported by environmentalists, are also killed. But they look the other way, because it's green energy. If you killed an animal on the endangered species list, the environmentalists would be up in arms. Green energy kills them and environmentalists want to look the other way.
Marcellus wrote:Oh absolutely! I agree. It's never going to be "100% green". But I'd rather have a solar park or wind park next to my city than a nuclear reactor or coal/oil power station. Those things will never pay off in the long run, considering how much it costs us to clean up pollution caused by environmentally inefficient ways of producing power or products for that matter. The true cost of many things that we do is hidden to the plain sight.
Well, nuclear plants aren't likely to be located directly next to a city in the USA, as well nuclear energy is considerably more safe than it was even 20 years ago. Nuclear energy is also rather young compared to the others. Windmills and Dams (WaterWheels) have been around for hundreds if not thousands of years. They may not have made electricity but the tech is not new.
In actuality all power generation is done the same with exception to solar which doesn't use a generator. Water, Wind, Geothermal, Oil, Coal, Gas, and Nuclear all create electricity in the same exact way via generators. Wind and Water turn their generators directly, while the others are turned via steam. The only difference between steam driven power generation is the resource used to create the steam.
Currently in the USA, natural gas is the cheapest means to create electricity, with Nuclear directly behind it. Nuclear is however the most effective and environmentally friendly (uranium is a naturally occurring element and can be recycled and reused to reduce waste). One metric ton of uranium (nuclear fuel) produces 44 million kilowatts of electricity. It takes 20,000 metric tons of Coal and 8.5 Million cubic meters of gas to create the same amount of electrivity.

Hell the first airplane by the Wright brothers didn't even fly for more then a minute if I recall correctly. Now we have planes that can fly for hours. If we just invest the time, money and effort onto renewable energy I'm sure we can start making great improvements to it. like I said before, if the US just cut their military budget in half, we would still have the largest budget in the world, but we would also have a huge amount of money invested into renewable energy.
Sorry but that would require you to defy the laws of physics. Solar and Wind power generation can only generate so much power. Solar converts energy, it will never be as efficient as other energy sources. Wind power requires the wind to turn generators/motors, to create more electricity you need larger generators. The large the generator, the more force is required to drive it. The wind isn't a constant force and there is this thing called friction. Also take note that wind and water power generation have location limitations. Wind farms can't just be placed anywhere and water power (dams) requires a large amount of well moving water.
