January 24th, 2014
Via Energy Daily, a comparison of the economic benefits of different colored roofs: Looking strictly at the economic costs and benefits of three different roof types-black, white and “green” (or vegetated)-Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found in a new study that white roofs are the most cost-effective over a 50-year time span. […]

November 21st, 2013
Via Mosaic, a look at solar securitization: Financing Rapid Growth Every four minutes, a new solar photovoltaic system is installed in America. By 2016, new installations are expected to occur every 90 seconds. Two thirds of the solar capacity in the U.S. has been installed in the past 2.5 years and in the next 2.5 […]
