Obama, during his campaign said that US will explore alternative energy sources than depending on oil, he mention wind, solar and coal. Even president Bush had the same view but ended his 8 year tenure without doing anything. it is not so easy as it might sound since it is very capital intensive and requires a lot of research.
Obama has successfully manage to use this to bring down the the price of Oil in the international market by intensively talking about wind and solar energy and how much money the US will spend on these projects.

DonĀ“t believe the hype.
