Wind energy is proving to be a good investment in Illinois. It helped save Illinoisan's about 100-million dollars last year. Kevin Borgia, with Wind on the Wires, says that's because wind energy has no fuel costs so generators can bid very low prices for electricity.

Borgia says coal and other energy companies don't have the luxury of bidding as low as wind generators because they have to take fuel costs into account. There are more than 25-hundred megawatts of wind generation in Illinois but Borgia says wind growth is in danger of tapering off unless Congress extends a Wind Energy Production Tax Credit.
