Hawaii’s 358 MW of installed solar PV in 2013 represented 12.9% of peak electric capacity, according to Clean Edge’s newly released 2014 U.S. Clean Tech Leadership Index. This is the highest portion of any U.S. state.
While California has a larger raw volume of solar PV installed at 5.18 GW, due to the state’s much larger population and electricity use this represented only 7.0% of peak capacity. New Jersey came in third place with 1.18 GW, representing 6.25% of peak capacity.
Solar deployment was one of many metrics that the report looked at within three broad categories of technology, finance and policy, spread over a variety of technologies including renewable energy, clean transportation and green buildings.
