11 Reasons for wind energy (1/3) 1. Wind turbines lessen the risks of climate change Millions of people suffer from the effects of climate change worldwide. In order to keep further risks of climate change at bay, developing countries need to decrease their CO 2 emission with at least 8095 percent before the year 2050.

At the present time, things like pumpedhydro are breakeven at best. It's far cheaper to build 25% more wind turbines and just idle the ones you don't need. Once we have a costefficient way to store power, there will be a pretty quick rush to build power storage stations. The money you could make doing this would be astronomical.

Wind turbines are increasing in size, with the world's largest standing at more than a quarter of a kilometre high. A professor of renewable energy considers why turbines are increasing in size at such a rapid rate, and if there is a limit to how big they can go. Bigger blades can generate more electricity, he says, but make it more difficult ...

Windmills work by using the wind to turn their blades, which in turn spin a generator that produces electricity. Plus, Windmills can also be connected to a pump, which pulls water up from a well using the wind. Windmill Parts There are two parts to a windmill: the rotor and the generator. The rotor is the part that turns in the wind.
