Two years ago, the deeply conservative state of Kansas repealed a law requiring twenty percent of the state’s electric power to come from renewable sources by 2020, seemingly delivering a blow to the state’s environmentalists. Kansas zipped past that twenty percent goal in 2014 and actually produced more than thirty percent of its energy from wind by 2016. This underscores the reality that some of the fastest growth in renewable energy is occurring in states led by Republican governors and legislators.
