America should attack global warming by … painting rooftops and road surfaces white. Seriously. No kidding.
Among those promoting the idea is Energy Secretary Steven Chu, a big-thinking physicist who has a bully pulpit and influence over billions in research and stimulus funds.
Whitening the world’s roofs and roads would have the same effect on global warming as removing all the world’s cars for 11 years, he said.
So for new buildings, highways and retrofits, choose white!
This initially sounds like a strange idea. But, living in Florida, I beilieve it would help significantly with cooling homes as well as the global warming it would benefit. I never understood why people would put dark shingles on their house down here.
