Energy policy is once again up for debate on Capitol Hill with Senator Jeff Bingaman (D-NM) expected to introduce an amendment today that would require 15 percent of electricity generated in the U.S. to come from renewables by 2020. The legislation will be countered by Senator Pete Domenici (R-NM), who is planning to offer a "weaker" amendment that defines coal and nuclear as clean energy, and eligible for renewable credits.

"There is no reason to dilute the bill. [Renewables] are ready for market now. They're cost competitive now and they don't require continuing operating and construction subsidies." -- Jim Rubens, Union of Concerned Scientists
