Solar viability marches on with the US Navy making a commitment to a massive system. Here's an excerpt from that story:
In the largest renewable energy purchase ever made by the federal government, the Navy just agreed to build a 210 megawatt direct current solar facility in Phoenix, Ariz.
To put that wattage in perspective, the Solar Energy Industries Association gives the national average of households powered by 1 megawatt of solar energy as 164, or roughly the population equivalent of Duluth, Minn. Instead of juicing Bob Dylan’s hometown, the Sempra U.S. Gas & Power facility’s 650,000 panels will run current to 14 Navy and Marine Corps installations in California by the end of 2016.
The Navy’s been doubling down on solar lately, with a plan to build solar panels for parking lots at the Joint Base Anacostia-Bolling installation in Southeast D.C. and, more impressively, a 42 megawatt large-scale solar generation farm at a Naval Submarine Base in Kings Bay. But nothing is on the scale of this Arizona plan.
