Obama says high gas prices show need for new energy sources
Obama said the government would look for ways to run vehicles on fuels beyond gasoline, such as advanced biofuels and natural gas. "We can't just allow ourselves to be held hostage by the ups and downs of the world oil market. We have to keep developing new sources of energy," Obama said in a speech at the University of Miami.
