If your actual expectation is that we will stop, and you’ll be pessimistic for anything else, then yeah…you are definitely going to be pessimistic. It’s not realistic to expect people to just stop using power. It’s not realistic to expect people to just use power when the wind is blowing and/or the sun is shining. It’s not going to happen, so you have to gauge the response and the expectation on reality, which is we need to do this while not having the world meltdown economically and socially with people in complete rebellion because they don’t have any power.
The problem has been the ‘anti-nuke hippies’ you mentioned along with many environmental groups who touted wind and solar as the be-all and end-all to solve all our problems. It never was going to without some way to store the excess energy (which, of course, changes the price structure and takes away the killer argument that wind and solar is cheaper than nuclear), and it was frustrating to be in these discussions a decade ago and trying to explain that with all of the kumbayah and unicorn fuzzy feeling stuff going on. I’m not sure why we need to blame the ‘corruption that surrounds the nuclear industry’ with specific examples in the US, because while that did happen, that’s not the reason why we stopped building nuclear power plants…and by ‘we’ I mean the world, not just the US. It WAS a concerted effort by your ‘anti-nuke hippies’ and other groups, and it has a real impact on this problem now. And, it’s STILL having impacts, as we are STILL not building the plants at the rate we should be. We are back to baby steps, with, IIRC from a recent discussion on this, the US maybe build 2-3 new plants that maybe will be ready in the next few years, assuming they are actually complete. I might be misremembering, and maybe 1 is ready soon or even online now. We SHOULD be building 10 times more than that and should be building a ton of the small modular plants or at least a handful as testbeds and proof of concept systems, with an eye towards full production going flat out for the next decade or so.
We aren’t, and we won’t be for maybe that decade. All the while, the only alternative is going to be fossil fuel power plants, and, perhaps, energy storage systems to go with the wind and solar plants we have along with the trickle of potential new nuke plants with the hope of more down the road. All of that is going to take a lot of time and a lot of resources.
The only good thing there is, at least in the US, those will mainly be natural gas instead of coal. But China is still building a ton of new coal plants, and so is India. China is also building a ton of new coal plants in other countries, though they SAY they will stop proposing new ones. As their lips are moving I’ll believe it when I see it.
But, I still don’t think all hope is lost. We just have a accept that the climate has changed, and prepare for the bad things that will happen, and work towards doing as much mitigation as we can with an eye toward shifting things so that we are at net zero, with perhaps bringing some CO2 capture technologies in play to help speed up the mitigation.
