New legisation introduced in the U.S. Senate seeks to increase dramatically the alternative fuel requirements for U.S. utilities.
"A bill about to be introduced in the Senate would push utilities to generate drastically more of their power -- 15%, compared with the current 2% -- from sources such as wind or the sun by 2020. While three similar measures have died after passing the Senate, this one has powerful bipartisan support.
Environmental groups have long sought a federal law requiring utilities to use a variety of cleaner natural resources. Several states already direct utilities to meet minimum standards; a federal benchmark could give utilities a uniform interstate market and make compliance easier.
The measure would authorize the Department of Energy to set up a national market to trade what are called renewable-energy certificates, which would be created and sold by producers of a certain amount of renewable energy. Utilities that generate more wind power than they need to meet the renewable-energy standard could sell credits to utilities in areas without much wind, and these utilities could use the credits to meet the standard. At the end of the year, the utilities that still don't meet the standard would face a civil penalty."
