Fighting Global Warming With Color
Jonah Goldberg has re-ignited an interesting meme: Replacing black roofs on buildings with white ones and adding chalk dust to asphalt to make our roads light gray rather than black. This, supposedly, will conserve energy, make urban areas cooler, and even help reduce global warming. Blogospheric luminaries from Kevin Drum to Megan McArdle to Matt Yglesias are on board.
I haven’t the engineering background to assess the feasibility of this but it sounds plausible. Mark Kleiman is likely right, though, that the proposal will go nowhere because it isn’t sexy enough to sell politically and there isn’t enough money to be made to generate major lobbying efforts.
