WASHINGTON (CNN) - Former Virginia Gov. Jim Gilmore suggested Tuesday at the GOP presidential debate the United States turn towards nuclear power and other alternative energy sources.

"We're going to have to in fact look to all sources: ethanol, biomass, coal, clean coal, the opportunities for natural gas, and nuclear power."

"Nuclear power will help this whole issue of global warming," Gilmore added.

Gilmore was responding to a question posed by CNN moderator Wolf Blitzer, who pressed the candidates on whether oil executive profits were too high.
