The problem with wind farms is if you build a wind farm that can produce so much electricity, you need to build say a coal or some other plant that can also produce that amount to cover for it when the wind isn't blowing.,(reply>), Because wind is the ONLY source of renewable energy on the planet! AND there are NO ways to store energy! AND we can NOT invent new ways of storing energy because as everyone knows technology is NOT advancing at an incredible rate!<br>Also the battery thing Tom mentioned. Doesn't sound like the most brilliant idea assuming that you might actually want to drive that car but it's a start.
