From PAUL KRUGMAN

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.
Speaking of propaganda: Before I get to solar, let’s talk briefly about hydraulic fracturing, a k a fracking.
Fracking — injecting high-pressure fluid into rocks deep underground, inducing the release of fossil fuels — is an impressive technology. But it’s also a technology that imposes large costs on the public. We know that it produces toxic (and radioactive) wastewater that contaminates drinking water; there is reason to suspect, despite industry denials, that it also contaminates groundwater; and the heavy trucking required for fracking inflicts major damage on roads.
Economics 101 tells us that an industry imposing large costs on third parties should be required More…
