Most people dont know that wind turbines produce very little, if any,energy on frigid winter days. Texas, which produces a lot of wind energy, learned this the hard way in the unusually cold spell in February 2011. Without enough wind to keep the windmills turning, Texas was forced to buy electricity from Mexico, and those nasty neighbors tripled the price for Texas utility companies and their customers.
They are putting up so many of those turbines on Texas it is amazing. They have learned nothing. Saw three huge cranes working one new field of turbines. I think maybe Texas Farmers just want the birds killed. Lol.
