Solar Power could save us - why the fuck aren't we doing anything about this!!!

According to Digital Journal, and a lot of other people, including this guy I saw on Bill Maher, if we utilized the solar power that could be generated from 6 hot spots on our planet, we could power the entire Earth and then some. This would decrease our dependency on fossil fuels, decrease global warming, lower oil prices, and other good things. Why countries like the US aren't investing in these types of resources is ridiculous, choosing instead to waste money on the war. Seriously sometimes I feel like I'm taking crazy pills.
