Warren Buffett is apparently not an unadorned green but instead falls in the category of self-interested capitalist. Shocker, right?

The billionaire is under scrutiny because one arm of his vast Berkshire Hathaway conglomerate – the Nevada utility NV Energy – is trying to keep a 3 percent ceiling on net-metered solar in the state. Meanwhile, other arms of Berkshire Hathaway are taking advantage of tax credits with utility-scale wind farms and solar arrays.

“It always comes down to money. It’s legal to lobby and it’s legal to push your agenda, so he’s going to push his agenda even if it looks kind of hypocritical.” – Jeff Matthews, an investor and author of books about Berkshire, to Bloomberg

NV Energy told Bloomberg that it “supports solar in all its forms” but believes net metering “increases costs to all customers and we oppose putting upward pressure on rates.”

Solar advocates generally dispute that kind of analysis, maintaining that utilities (and regulators) don’t take into account the benefits that distributed renewable energy generation brings.
