By 2015 or so, the average silicon chip will consume about 150 watts of electrical power, turning this into heat a thought which is already taxing the minds of some engineers.

ECONOMIST: MONITOR

We're also working to make sure that we can start turning things like plants and woodchips into heat, power, and biofuels, and that will create new economic opportunities for rural communities.
