Looks like Southern Company (SO) bet on the wrong horse.

The report finds total U.S. wind power capacity grew to 47,000 megawatts by the end of 2011 and has since grown to 50,000 megawatts, enough to power 12 million homes annually — as many homes as in the entire state of California. And as wind energy capacity has grown, more and more wind turbines and components like towers, blades, gears, and generators are “Made in America.” Nearly 70 percent of all of the equipment installed at U.S. wind farms last year came from domestic manufacturers, doubling from 35 percent in 2005.
Why should SO worry? Wind only came in second in added capacity. Because of this:
In addition to strong gains in domestic wind manufacturing and capacity, the report finds that as wind technology improves, costs are coming down. Technological innovations are helping make longer and lighter wind turbine blades, while improving turbine performance and increasing the efficiency of power generation. At the same time, wind project capital and maintenance costs have continued to decline.
And wind doesn't even have Moore's Law going for it as much as solar does, plus solar is usable in more areas than wind. Add wind and solar and why do we need much natural gas? (Or any coal or nuclear?)
