Forget 'Green' Energy Stocks — For Now

Alternative-energy stocks may be running out of gas, says Jerry Castellini of CastleArk Management.

He told CNBC that the recent plunge in crude oil prices — and the smaller decline in gasoline prices — has removed much of the motivation to identify and develop "green" and renewable energy sources.

"They really needed $100 a barrel [oil] to make the economic case for these transitional technologies," he said.

Therefore, Castellini said, the smart money should be considering "traditional energy companies" — despite lower crude prices.
