How long until solar beats gas?

We've heard even German coal importers say solar beats coal. How long until clean solar beats dirty natural gas fracking?

Southern Company has already cut energy production from coal in half, from 70 or 80% to 35%. Unfortunately, SO did that mostly by shifting to natural gas. Natural gas produced through "a revolution in shale gas", commonly known as fracking. Do we want to trade dirty water for clean air?

Unlike Johnson & Johnson and Dell (and Coke and Pepsi and Amazon and and more than a dozen more, including even Wal-Mart), the Southern Company has not cut ties with ALEC and its pro-fracking and anti-solar campaign. Why is the Southern Company betting on a dirty horse?

How long until SO CEO Thomas A. Fanning's "one day" when renewable energy becomes economical? Sooner than his prediction of next decade, as in two years ago solar crossed nuclear, wind is already at parity with nuclear, and even Southern Company realizes coal doesn't beat anything anymore.

How long before solar beats natural gas, relegating gas to much-reduced use as a backup for sun and wind power, as John Blackburn already projected in March 2010 can happen in North Carolina?

How long will it take for the sun and the wind, with a little water and even less natural gas, to power the world? How long? Not long.

Because the arc of the solar Moore's Law is long, but it bends down for price per watt, while the price of fracking, no matter the quakes and dirty water for ever, does not.
