Not 100% certain this is the best place to ask this question, though I've asked questions here before, and there seems to be some smart and helpful people here. I was pondering wind farms and thinking about T. Boone Pickens' idea of huge expansive wind farms to generate energy. Apparently the goal is to generate around 4 giga watts of energy with these farms. I'm wondering that if on such a grand scale might there be any possibility of inadvertent side effects? Such as the misdirection/interruption of continental currents, and thus adversely effecting weather? Perhaps the question is best posed to a meteorologist, not sure.
