No worries, Obwana assures us that clean energy--whatever that is--will save the day. Of course that day might not come for a few decades--if ever.
I clearly remember when Carter was president and sadly told us that all the oil would be gone by 1975. Carter was about 17 times smarter than Obwana and he wasn't near the liar, but they both have some of the same stupid notions about energy and the environment.
