Google was the second most active cleantech investor last quarter, has unveiled a $4.4 trillion U.S. energy plan, and could one day actually make revenues off energy management tools. But Google CEO Eric Schmidt has his own plans when it comes to energy and politics. Schmidt, who has been acting as the spokesperson for Google’s energy plan, has also been advising the Obama campaign on both energy and technology issues and tells the Wall Street Journal that he will personally back Obama and join the campaign trail at an event on Tuesday. Earlier this month I wrote an op-ed for Forbes suggesting that Obama should fill his planned Chief Technology Officer with a Chief Cleantech Officer and appoint Schmidt to the role. Who knows, maybe that’s the plan? For my complete take, check out the full story over at Earth2Tech.
