Gore Aims High on Renewable Energy Goal for U.S.
July 17, 2008
UPDATE
Former Vice President and Nobel laureate Al Gore outlined a bold climate goal for the nation Thursday, challenging the U.S. to create every kilowatt of electricity through renewable energy sources within 10 years. To meet his goal, Gore said nuclear energy output would continue at current levels while the U.S. would need to dramatically increase its use of solar, wind, geothermal and clean coal energy.
