> How much of this is based on how expensive it is to bring a powerplant online? How much of that expense is based on endless lawsuits from environmental groups and weaponized environmental laws? Why can the navy without those restrictions build safe reactors for ~$2million/megawatt? Pretending it's all the fault of the bad environmentalists is a bit ridiculous. A nuclear powerplant is a tricky thing to create. A lot of projects had delay, often not due to any environmentalists or anti-nuclear people, but because the parts failed their internal control, which demonstrates that it is tricky to build. A nuclear powerplant is a huge provider that cannot be turned online for usually ~10 years, so you can also understand the complexity and the uncertainty: we are not able to predict the price of electricity or what will the electricity grid will look like in 2-3 years, and yet they need to predict it for a given region in 10 years. And some environmental laws are frivolous or turned out the be incorrect (the same way some people who at the time were against some environmental laws turned out to be incorrect years later), but some laws are just legitimate and it is simply not fair to pretend that the opinions of some people should just be discarded because you have a different opinion. I myself don't always agree with some law, sometimes anti-nuclear, sometimes pro-nuclear, but a given fraction of these laws will exist, it is just the reality. It's like saying "communism would work if it was not for people who don't like communism": people who don't like communism will always exist and if your model require a world where it is not the case to work, then your model is stupidly unrealistic.

> if your model require a world where it is not the case to work, then your model is stupidly unrealistic And yet, our world contains multiple cases where it is the case that nuclear is being built today, at reasonable costs, and with great success. The two examples I've given in this thread are China and the US Navy. Some others include Japan and South Korea, both of which are notably not dictatorships. What's frustrating in this discussion is policy and management decisions made 50 years ago are assumed to be the steady-state immutable reality in western countries. My argument is not that nuclear is the best economic play. It's that if you believe that continuing to burn natural gas and coal is an existential risk, you should be spinning up every option all at once as aggressively as you can.

  What? Who is saying that nuclear cannot be successful, this has nothing to do with my comment. Did you read one sentence without understanding the meaning? It is simple: some environmental laws are a legitimate ask from some people, whether you or I agree with the ask itself. It has nothing to do with the nuclear, it is about your argument framing the existence of environmental laws as the reason it does not work. If nuclear cannot work well in some countries because in some countries there are people who ask legitimate things, the problem is not these people, the problem is that the nuclear model is not adapted to the reality of these countries. But again, as I've said, it is not even the case: the difficulties with nuclear are not limited to "some environmentalist". > It's that if you believe that continuing to burn natural gas and coal is an existential risk, you should be spinning up every option all at once as aggressively as you can. That does not make sense. If you want to write a software that does something, you don't just spinning up Linux, Windows, Mac, and start writing code in Java, C++, python, typescript, erlang, ... at the same time. What you do is: you write a decision matrix, score it, and _choose one strategy_. In the context of the climate crisis, the strategy can mix different technologies ... or not. The fact that it does not does not mean that this particular strategy is worse than another. In particular, budgets are obviously limited, so spending X$ on project A may lead to a successful project A while spending X/2$ on project A and X/2$ project B may lead to both projects A and B failing. (and if you don't think it's true, just increase the number N of projects until X/N$ is ridiculously too small to do anything. According to your sentence, you said you should be spinning up every options all at once as aggressively as you can, so you cannot do only N-1 projects, you need to split your money amongst the N projects). When it comes to climate change, I was 100% pro-nuclear 20 years ago. Now, in some countries, it is too often a money pit (not because of regulation or the bad environmentalists) that is wasting money that could have helped the climate. If you believe that continuing to burn natural gas and coal is an existential risk, you should spend your time, money and energy to real solutions instead of achieving nothing by trying to do everything all at once without a plan.
