President Barack Obama said tax breaks for natural-gas powered trucks will help the U.S. cut its dependence on imported oil.

Obama, in his second day promoting policies laid out in his State of the Union address on Jan. 24, proposes a credit equivalent of 50 percent of the extra cost of purchasing a natural gas-powered truck compared with one that runs on diesel or gasoline.

“We have a supply of natural gas that can last America nearly a hundred years,” Obama said in the text of remarks in Las Vegas at a United Parcel Service Inc. natural gas refueling station built with the aid of money from the economic stimulus. “Developing it could power our cars, our homes, and our factories in a cleaner and cheaper way.”
