US Renewable Energy Subsidies Dropping, While Renewable Energy Continues To Grow Fast

Federal subsidies for renewable energy—including biofuels for transportation use and renewable generation of electricity—dropped to $6.7 billion in fiscal year (FY) 2016, a 56% decline from FY 2013. Renewable subsidies in FY 2010 and FY 2013 were approximately $15 billion, more than double FY 2016 levels, as support from the American Recovery and Reinvestment Act of 2009 (ARRA) lessened.

(Dark aerosols, like soot, tend to absorb light; other aerosols such as sulfates and nitrates, reflect light. In both cases, the aerosols prevent light from reaching solar panels below.)
