The real problem is that there are no renewable solutions for base load, nuclear is the best we’ve got. Renewables are good, but they’re spotty, you can’t produce renewable power on demand or scale it on demand, and storing it is also a problem. Because of that you still need something to fill in the gaps for renewables. Now your options there are coal, oil, gas, or nuclear. That’s it, that’s your options. Pick one.
If we can successfully get cold fusion working we’ll finally have a base power generation option that doesn’t have (many) downsides, but until then nuclear power is the least bad option.
So yes, if you tell them “no nuclear”, you’re going to get more coal and gas plants, coal because it’s cheap, and gas because it’s marginally cleaner than coal.
