FILE - In this Friday, Sept. 30, 2011 file photo, workers continue to build rows of solar panels at a Mesquite Solar 1 facility under construction in Arlington, Ariz. Even as renewable power projects get a boost from the federal government, there’s a tangle of complications preventing states like New Mexico and Arizona from converting the obvious potential into real watts that can charge smartphones and run air conditioners thousands of miles away. And few of those complications are as clear as the need for transmission lines in a region where the sun is plentiful, but the demand for its energy is not. (AP Photo/Ross D. Franklin, File)
