A cleaner future is possible and has become much, much less expensive to achieve lately too.
Battery deployment curves will soon be looking similar to this one on solar signaling that fossil fuel age will soon be ending.
Yes, PV panels don't produce electricity at night and less when it is cloudy and/or rainy, but they are a lot less expensive than the alternative sources of electrons and pair together really well with batteries to reduce the risk of those scenarios.
Do you recall that expensive new nuke plant in Georgia that took twice as long to build and more than twice as much to cost as projected?
Well, it appears that it is experiencing an unscheduled shut down.
