Solar energy is on its way

This evening, I participated at an interesting forum energie zürich event. I learned, for example, that solar energy has quite a large potential. Watching this 9½ minute video, which I came across through this blog posting by Alexander Osterwalder, I got a similar impression. In the video, Mr. Jigar Shaw mentioned, for example, that in 2100, the vast amount of our energy will come from solar. Mr. Shaw also asks: "Can we do it sooner?" What do you think?
