Wind Energy


Wind energy is a becoming more and more known to the world. It's said that one turbine would take up 2 to 3 acres of land. Transporting the turbines and the all the materials would take a lot of energy but could be a possible thing to save energy and earth in the future. The turbines are spun by the wind which in turn makes the gernerator work. In the generator there is a magnetic feild that spins around a conductor (like a piece of copper). This in turn creates electricity which can be distributied from a wind farm to houses. For an average house if you'd need a 10 Kw generator and it would cost about $35,000 to $50,000. It has actually been around for many years now. Some of the pros of wind energy is that it doesn't pollute the air, renewible, and doesn't use fossil fuels. But just as there are good things there are some that are bad. Wind turbines take up a lot of space, the cost is substancial, and produces noise pollution. Here is a site that shows how wind turbine work if you need more information.
