It was up to 70 for the first time this year in DC today. I was thinking about bumping this topic because there's been a lot of news in the energy policy world in the aftermath of the Green New Deal hype.
New Mexico just announced it's going 80% renewable / 100% clean (which includes hydro & nuclear and other carbon-free technologies) by 2050. Minnesota, Wisconsin, Illinois, New York, Nevada, and Washington are all considering similar if not more ambitious legislation, with Maine and Michigan potentially doing the same. Only Hawaii, California, DC, and some cities have passed similar legislation in the US. Pennsylvania is also considering a law to subsidize it's nuclear plants, similar to how Illinois, New York, and New Jersey have. I'm not a fan of nuclear power long-term but I'd rather see coal plants get retired first.
As I've explained before, the end of coal (and eventually gas) generation is not a matter of if but when. Most of the wind generation is in Great Plains states and solar is growing fastest in Texas, too. It's all about economics and shouldn't be a political issue. That said, by 2020, there may not even be that much need for a national policy like the Clean Power Plan or Green New Deal with all of the state and local legislation.
