"WASHINGTON -- President Obama moved on Wednesday to bolster the nation’s production of corn-based ethanol and other alternative liquid fuels and ordered the rapid development of technology to capture carbon dioxide emissions from the burning of coal.
The president is trying to expand the portfolio of American energy sources to reduce emissions of greenhouse gases, a factor in global warming, and spur advances in alternative technologies. Last week he expressed support in his State of the Union address for increased generation of nuclear power and offshore drilling for oil and gas.
Mr. Obama’s motives are environmental, economic and political. He is trying to address climate change by replacing dirty fuels with cleaner sources, jump-start an American clean-energy industry, reduce dependence on foreign oil and attract Republican votes for legislation to do all three."
