The Senate passed a new energy bill Thursday that aims to boost the nation's use of renewable energy and promote energy efficiency. H.R. 6, the CLEAN Energy Act of 2007, focuses primarily on cars but if passed and signed by the President would also set new energy-efficiency standards for appliances and lighting. It also requires the federal government to speed up its adoption of more efficient lighting in public buildings. Supporters say the bill reflects a shift away from promoting fossil fuels to supporting other energy sources such wind and biomass to make electricity and ethanol to power cars and trucks.
