Wind turbines and solar panels accounted for more than two-thirds of all new electric generation capacity added to the nation’s grid in 2015, according to a recent analysis by the U.S. Department of Energy. The remaining third was largely new power plants fueled by natural gas, which has become cheap and plentiful as a result of hydraulic fracturing.
It was the second straight year U.S. investment in renewable energy projects has outpaced that of fossil fuels. Robust growth is once again predicted for this year.
And while Republican lawmakers in Washington have fought to protect coal-fired power plants, opposing President Barack Obama’s efforts to curtail climate-warming carbon emissions, data show their home states are often the ones benefiting most from the nation’s accelerating shift to renewable energy.
