Buffett’s MidAmerican will Own 14% of US Solar

Warren Buffett’s MidAmerican Energy Holdings Co. accounts for 6 percent of U.S. wind-energy capacity and will generate about 14 percent of the nation’s solar power when it finishes three solar farms under development.

When the projects are complete, the company will have invested about $13 billion in its renewable-energy portfolio, Buffett wrote in his annual letter to shareholders today.
