Currently everywhere in the world coal and nuclear power is back again, even in Europe, and especially in Germany where even the Green party is in the government. The wacko Green and Greta idis, nobody wants to hear them anymore, everybody wants and needs and seeks affordable energy, that is electricity and gasoline generated also by using coal and in NPPs.

Solar can make some sense for industrial loads that are drawing during the day but a lot of Texas industry, refining for instance, runs 24/7 so it doesn't satisfy their needs in darkness. Industrial scale batteries aren't coming into existence fast enough. Residential application of solar is a bit different (panels on your home). In states with "grid-tie" laws the panels on your home energize an inverter to create AC that by law can only be sold back to the electric company meaning that in the event of a grid outage they cannot power your home...unless you have an approved residential battery setup (Tesla and others make them). The problem there is that residential battery setups are very expensive and have a realistic lifespan of about 10 years. In Florida mostly I see people settle on the cheapest type of backup power which is a generator connected to natural gas. Backup power is a real issue here because of hurricanes. Locally we have nuclear power but the grid is deenergized in advance of a hurricane arriving (they don't wait for it to be damaged while energized) and its usually off for about 10 days, generally when the state is experiencing peak high temperatures and humidity. There is also the potential for residential solar installations to be destroyed in hurricanes. My neighbor installed an large solar array then was shocked when I told him it cannot supply backup power. He said he would look at batteries but a few weeks later he installed a natural gas generator. It really is the cheapest solution but, of course, you are going to get a massive gas bill after a significant power outage. Florida is also instituting a "minimum charge" law where even if your solar array brings your net-metering grid usage to net zero you will be charged a minimum fee which seems to be about $30 dollars a month. Pretty annoying if your solar array covers your entire usage.
Anyone serious about global warming should want a Manhattan Project-style program to build nuclear power plants en masse. Decarbonize the entire grid in 10-15 years. Of course shitlibs never propose anything like this, for the same reason they don't recognize that growing the population 25% a decade via immigration is bad for the environment.
Nobody doubts that solar (and wind) can be useful. But they can't supply baseload power and the variability problem is huge. For baseload power and to cover seasonal variance, we could futz around with hydrogen storage or build pumped hydro... but why not just go with nuclear?
I think nuclear is the short term answer. Need to up our game on storage of spent fuel materials though. I keep waiting for fusion but its going to be a long long time before that is workable. Hydrogen is a great fuel but its scary dangerous. Lately there have been some advances on making hydrogen though. I think there is definitely a role for hydrogen for power generation but I don't think I would mess with a hydrogen or hydrogen-fuel-cell car. It does make electric cars more sensible, certainly better than charging them from a coal-fired or natural gas based electric grid.
There are more grid level storage systems than I care to count at this stage. The problem facing engineers and managers in 2022 is trying to decide on which one to invest in. There will be front-runners in a couple of years but people keep inventing more and more.
Dudes, none of this matters. Green cannot ever replace fossil fuels. Not even the almighty nuclear option. We simply use too much energy from fossil fuels. And that habit is why we will always need them. Green can supplement, but never replace it. Ever. And fusion is sci-fi, that will never happen. You can't make a fucking star on earth. DUH!!!!!!
