Requiring utilities to buy renewable power
Currently about half the states require their utilities to buy a certain percent of their electricity from renewable sources -- usually 10% to 20%.

In addition to cutting greenhouse gas emissions, supporters say it provides a guaranteed market for renewable power, thereby spurring investment in the sector and helping reduce costs as renewable technologies develop economies of scale. They are pushing for a federal law requiring utilities in all states to buy renewable power.

Opponents say a federal law is unfair, as some states (think Arizona for solar or North Dakota for wind) are more blessed with renewable energy sources than others.
