watch speech excerpt¹ on energy

President Bush called on the United States to diversify² its sources of energy during his annual State of the Union address.

Mr. Bush said dependence³ on foreign sources of oil leaves America more vulnerable to hostile regimes and terrorism. The president called for reducing gasoline usage in the U.S. by 20 percent over the next decade. He said the goal can be met by increasing the supply of renewable and alternative fuels and reforming fuel economy standards for cars.

Mr. Bush also called for greater use of clean coal technology, solar and wind energy, and nuclear power as alternatives to oil. He called for research on hybrid⁴ automobiles⁵, and investing in new methods of producing ethanol.

The president said new technologies will help the United States become a better steward⁶ of the environment and confront what he called the serious challenge of global climate change.
