As of August 2019, 29 U.S. states and the District of Columbia had renewable portfolio standards (RPSs), and eight others had non-binding renewable portfolio goals. Three states also had clean energy standards, which set targets for low-carbon non-renewables, like nuclear, and two had clean energy goals. Our monthly infographic in September 2019 shows how shares for each source in states with targets have changed. Here’s an interactive overview of net generation data for states with RPSs, sorted by non-renewables, all renewables, and only wind and solar.

Non-Renewables

Coal’s share in nearly all states has fallen markedly, most-notably in the New England region. Natural gas’s share has also grown dramatically, especially in states like North Carolina. Nuclear’s share has remained steady, but petroleum’s share has diminished, for example, in New York and California. 

All Renewables

When all renewables are considered—including conventional hydropower—wind and solar only make up a small portion of most states’ renewable portfolios. California, New York, and Oregon, notably, have ramped up hydropower production.  

Wind and Solar

Still, nearly all states have increased generation from wind power. Especially notable are Texas, Iowa, and Minnesota. Solar generation, meanwhile, has ramped up dramatically in California, North Carolina, and Texas.
