This article suggests that Obama could improve the economy and reduce greenhouse gas generation by championing a switch to natural gas, since the US now has a lot of it. I think it is unlikely that Obama would do that. The Obama Administration has scared operators off from drilling for natural gas in the Marcellus Shale in upstate New York, and has indicated they would like to ban hydraulic fracturing altogether. The Obama Administration appears to be more inclined to punitive action to reduce energy consumption than to adopt an alternative strategy that would provide more low cost energy. They would like to promote high cost energy to help redcue consumption.
