Ecowatch : Some of the sunniest states in the country are actively blocking rooftop-solar development through overtly lacking and destructive policy landscapes, according to a Center for Biological Diversity report. The 10 states highlighted in Throwing Shade: 10 Sunny States Blocking Distributed Solar Development—Alabama, Florida, Georgia, Indiana, Michigan, Oklahoma, Tennessee, Texas, Virginia and Wisconsin—account for more than 35 percent of the total rooftop-solar technical potential in the contiguous U.S., but only 6 percent of total installed capacity.
