Interesting chart. In 2015 you could've argued that coal-to-gas switching was by far the biggest factor in decarbonizing the electric grid. But fast forward two years and renewables are now having just as large an impact:
US power sector CO2 emissions have declined 28% since 2005, and are now at the lowest level since 1987. About 75% of the decrease in power sector CO2 emissions comes from energy efficiency + renewable energy. Only 25% from switching coal -> natural gas.

the war on coal is working don't stop now #unnaturalworld
