US Presidency
2007

Extending hope and opportunity depends on a stable supply of energy that keeps America's economy running and America's environment clean. For too long, our nation has been dependent on foreign oil. And this dependence leaves us more vulnerable to hostile regimes and to terrorists who could cause huge disruptions of oil shipments and raise the price of oil and do great harm to our economy. It's in our vital interest to diversify America's energy supply. The way forward is through technology. We must continue changing the way America generates electric power by even greater use of clean coal technology, solar and wind energy, and clean, safe nuclear power. We need to press on with battery research for plug in and hybrid vehicles and expand the use of clean diesel vehicles and biodiesel fuel. We must continue investing in new methods of producing ethanol, using everything from wood chips to grasses to agricultural wastes. We made a lot of progress, thanks to good policies here in Washington and the strong response of the market.
