For GSS Energy Use chapter 10. Excerpt: President Obama ordered federal agencies Thursday to more than double their use of electricity produced by renewable resources, a directive that requires them to make solar, wind and hydro power 20 percent of the government’s energy portfolio by 2020. Federal facilities can install renewable energy projects or purchase electricity from them, according to Obama’s presidential memorandum, which is much tougher than a 2005 congressional directive for agencies to use renewable energy for 7.5 percent of their electricity needs by 2013. A White House spokeswoman said the government is on track to meet that goal. http://www.washingtonpost.com/national/health-science/obama-doubles-the-goal-for-renewable-energy-usage-by-federal-agencies/2013/12/05/e470388e-5dec-11e3-95c2-13623eb2b0e1_story.html.
