I'm not entirely sure why this surprises you. In President Bush's (I believe) 2006 State of the Union he pushed for more alternative energy production (including wind, nuclear, and solar). I personally disagree with his foreign policy, but towards the end of his presidency, he was pushing alternative energy. Taking that one step further, Texas (of all states) has installed the most capacity for wind production. I realize that both parties are trying to polarize the views of the other, but this shouldn't be surprising to anyone.
