T Boone Pickens’ recent oil price forecast — he sent oil surging last month with a forecast of oil at $150 a barrel by the end of this year — may not have come true yet, but that diminished the legendary oilman’s status as oil oracle among investors.

When he’s not making oil price forecasts, Pickens is busy investing in energy. He recently announced that his investment vehicle Mesa Power was putting $2 billion into a Texas wind-energy project, boosting clean energy stocks in the process and delighting the wind-energy lobby.
