Do we need innovative policy instruments? Forward-thinking (or even backward-looking) economic plans? Or will we make our way through this crisis with creative high-tech?
Many researchers suggest that, in fact, lo-tech is the way to go.
One study found that the high energy use of air-conditioning could be greatly reduced if we replaced black roofs with white or reflective one. Changing the color of a 1000-square-foot roof on an air-conditioned building could offset ten metric tons of carbon dioxide emissions.

There's also technology available that alot of the alternative and solar classes have been doing, using the dark colored roofs to preheat water, or heat air for other uses.
