There is some good news in regards to widespread renewable power in the United States. In 2017, 94.7 percent of new electric capacity generated in the country is from renewable energy sources, Engadget reports. On the surface this seems like good news, but it’s actually a mixed bag. While renewable energy appears to be on the rise, it is in large part due to the decline of coal.

According to Electrek, renewable energy sources provided 15.8GW out of 16.7GW of U.S. generating capacity, but the amount of energy created by utility scale fossil fuel production fell by 11.8GW as coal plants closed.
