Per ABC news: http://abcnews.go.com/blogs/politics/2013/08/solar-panels-finally-installed-on-white-house/ While installing solar panels on just one building in Washington DC doesn't do much for climate change, it's hard to ignore the cultural significance of solar panels on the roof of the White House. It sends a message to America, and the rest of the world, that the US is finally starting to take seriously climate change and embrace renewable energy, including solar power. Plus, it has a certain "cool factor". The article is not clear on what company is doing the work, or how much of the White House power needs the panels will take care of. In my opinion, the original solar panels from the Carter administration should have never been taken down. Bringing them back up is pretty neat.
