By Chris Mooney, The Washington Post. For GSS Energy Use chapter 10. Excerpt: The U.S. solar industry is on course for a new growth record in 2015, according to a new http://www.seia.org/research-resources/us-solar-market-insight report that finds that solar photovoltaic installations now exceed 20 gigawatts in capacity and could surpass an unprecedented 7 gigawatts this year alone across all segments. A gigawatt is equivalent to 1 billion watts and can power some 164,000 homes, according to the Solar Energy Industries Association (SEIA). The new report, from GTM Research and SEIA, covers the second quarter of 2015, which set a new record for residential rooftop solar installations in particular, a category that saw 70 percent year-over-year growth. 473 megawatts of residential solar capacity were installed, or nearly half a gigawatt. ...For comparison, according to the Department of Energy, the wind industry in the U.S. recently reached 66 gigawatts of installed capacity, with 13 more gigawatts expected to come online by the end of 2016. Overall, the U.S. had over 1000 gigawatts of electricity capacity installed as of the year 2012, according to the U.S. Energy Information Administration. So while still a minority of all electricity generation, wind and solar are, nonetheless, growing more and more significant on a national scale....  http://www.washingtonpost.com/news/energy-environment/wp/2015/09/09/why-solar-energy-is-poised-for-yet-another-record-year/
