Energy Secretary Steven Chu outlined the administration’s strategy.

Energy Secretary Steven Chu outlined the administration’s strategy for producing 80 percent of the nation’s electricity from clean sources by 2035 — and how much it might cost.  The strategy includes doubling the number of the department’s energy innovation hubs to six and adding more than $8 billion for new clean-energy funding in the upcoming budget, roughly a third more than in the president’s 2010 budget request. What each of the new energy hubs would specialize in is still a work in progress. But in a Wednesday morning event at the department’s headquarters, Chu announced that General Motors had signed an agreement to use advanced battery technology developed at Argonne National Lab   Even though President Obama did not mention the term “climate change” in the State of the Union address,  Chu said the administration will now emphasize economics in its energy strategy. But he added, “It’s very clear that the president thinks clean energy and our environmental goals are a very big deal to him.”
