Nuclear energy may seem expensive, because it has a big initial cost to get started, and we tend not to factor the long term effects of what we do. What is the cost of using fossil fuels? What is the cost and the damage done by climate change? An amount of money that we can't even quantify. So sure, burning coal/oil/gas may be cheap now, but it has an enormous long term cost that we just now are starting to pay.
This isn't about nuclear vs coal. It is about nuclear vs renewables. And what it really comes down to is that nuclear is really expensive and takes way too long to build. For every nuclear plant you build, we can build the exact same generation capabilities for about half the cost and it can be built in a quarter of the time[1]. That means that the renewable solution will have already mostly paid for itself before th…
Also other form of renewable are expensive. Unfortunately we are not so good at doing calculation on large scale. Just because installing a few solar panels is cheap, it doesn't mean that if we start installing a lot of them will maintain the same price.
Especially these days there is a shortage (they said due to COVID, but it's obvious that we are in a commercial war with China) of electronic components and semiconductors, guess what solar panels are made of? Where do you produce them, of course you can't rely on importing them from China, because China in a couple of years will not sell you anything, but if you start producing them in the US good luck making them cheap. And where do you even get the raw materials to start with?
Sure, a nuclear reactor does use a lot of materials, but are mostly steel and concrete, something that is produced in every industrialized country.
Do we even talk about energy storage? How do we realize that? Batteries? Lithium ones, good luck finding them at a cheap price.
Overall nuclear power is cheap, is just that we focus on the initial price that is obviously high and don't think that all the cost of transitioning to renewable energy added up are even higher. I don't say that a private investor will ever construct a nuclear power plant, the upfront cost is too high, but it's something that a government should build.
