Even as President Donald Trump boosts coal over clean energy, solar power is hitting new milestones in the U.S. and remains the leading source of new power. New reports released Wednesday by global energy think tank Ember and the Solar Energy Industries Association show the continued growth of solar and decline of coal in the United States despite federal policy. Ember says that in May, for the first time, solar supplied more of the nation’s electricity than coal, or 12.8%. Coal supplied 12.2%, its fourth-lowest monthly share ever. Trump has been helping the struggling U.S. coal industry while curtailing solar and wind. He says coal’s a great business.
