As an european i was really surprised that this would be one of the largest array in Colorado. It really is amazing thing that Aspen does something for the environment. But it still only produces enough energy for 20 households. So i think the attention that it gets in that article is a lil overrated.
Is the alternative energy industry serious that small in the US?
