With current technology costs and policy incentives, renewables are now unquestionably … [continued]

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. Despite the decline, renewable energy continued to receive a large share of total federal energy subsidies, accounting for 46% of the FY 2016 total.

Amazon’s Mighty Wind (Cleantech Talk #38)

Episode 38 of Cleantech Talk kicks off with a discussion of how, while China may be overperforming with its solar panel buildout, those panels are underperforming due to the low air quality there. Which is a polite way of saying that coal-combustion aerosols are reducing solar panels’ electricity harvest — by up to a third! (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.)
