Renewable energy sources generated 11.73% of US energy in early 2011, projected to reach 15% by 2035 if federal subsidies expire as planned. In 2012, focus will shift to state policies like renewable portfolio standards as federal action is unlikely in an election year. Key federal incentives that support renewable projects expire in 2012-2016, so the industry outlook is cautious without extensions. Solar continues advancing towards grid parity while targeting new applications, and geothermal and biomass also see some growth potential depending on policy clarity.
