DENVER -- When Colorado voters were deciding whether to require that 10 percent of the state's electricity come from renewable fuels, the state's largest utility fought the proposal, warning that any shift from coal and natural gas would be costly, uncertain and unwise.

Then a funny thing happened. The ballot initiative passed, and Xcel Energy met the requirement eight years ahead of schedule. And at the government's urging, its executives quickly agreed to double the target, to 20 percent.
