For decades the story of technology has been dominated, in the popular mind and to a large extent in reality, by computing and the things you can do with it. Moore’s Law — in which the price of computing power falls roughly 50 percent every 18 months — has powered an ever-expanding range of applications, from faxes to Facebook.
Our mastery of the material world, on the other hand, has advanced much more slowly. The sources of energy, the way we move stuff around, are much the same as they were a generation ago.
But that may be about to change. We are, or at least we should be, on the cusp of an energy transformation, driven by the rapidly falling cost of solar power. That’s right, solar power.
If that surprises you, if you still think of solar power as some kind of hippie fantasy, blame our fossilized political system, in which fossil fuel producers have both powerful political allies and a powerful propaganda machine that denigrates alternatives.
