In Warren Buffett's recent letter to Berkshire Hathaway shareholders, the investing legend quipped about his firm's purchase of Energy Future Holding, saying it was a mistake he made without the approval of his partner, Charlie Munger.

The real sweetener of this deal is NV Energy's intention to join the Cal-ISO, supplying California with much needed renewable energy.
