It’s become something of a cliché in energy-policy discussions: The United States is making headway on global warming and slashing its carbon-dioxide emissions all because of a glut of cheap natural gas that’s elbowing out dirtier coal power.

But perhaps that natural-gas story is overly simplistic. A notable new analysis by Trevor Houser and Shashank Mohan of the Rhodium Group suggests that America’s budding renewable-energy sector — particularly wind power and biomass — deserves a big chunk of the credit for driving down U.S. emissions. On the flip side, the report also suggests that coal could soon make a comeback.
