St. Louis – President Bush visited St. Louis Thursday to give the closing address at a conference on alternative energy.
Mr. Bush said even though gas prices are falling, the country should still invest in fuel sources other than oil.
The President said research into plant-based fuels such as ethanol and biodiesel is a good use of taxpayers' money.
"This country has got to use it talent and its wealth to get us off oil," Bush said. "And I believe we will do so, and I know the best way to do so is through technological breakthroughs."
Mr. Bush also urged more investment in traditional energy sources.
He said the nation should build more nuclear power plants and expand oil drilling in the Gulf of Mexico.
An anti-war protestor tried to interrupt the president by shouting "Out of Iraq now" and "Soldiers are not renewable." But police removed her from the convention center, while Mr. Bush kept speaking.
