In the party's weekly radio and Internet address Saturday, Sen. John Barrasso, R-Wyo., said Republicans support a more comprehensive energy plan that would increase funding for energy research, develop U.S. oil and gas resources and promote clean coal and nuclear power.

He said renewable energy such as wind and solar power is important, noting that Wyoming has world-class wind resources. But Barrasso said wind and solar only account for about 1 percent of U.S. electricity, far below what is needed to meet the nation's energy needs.

"There's enough oil shale in the Rocky Mountain West alone to power America for the next hundred years," he said. "As a nation, we need to be more energy independent. It is a matter of energy security, as well as national security."

"As we approach this Memorial Day, it is my hope that the Democrats can work with us to develop solutions to make our energy supply clean, affordable and reliable," he said.
