It's unsafe so it's never a good fit? That kind of reasoning is just noise. Unsafe for what? Compared to what? What alternatives, given the constraints, exist?

Finding something ideologically inconvenient doesn’t make it noise. There is simply no level of new carbon emissions which isn’t guaranteed to cause expensive problems around the world. That doesn’t mean we can’t switch everything instantly but that means we shouldn’t be building anything new which has a safe alternative — and in the case of electric power generation or cars, that’s especially clear because burning fossil fuels for that is more expensive so you’re paying extra to pollute more.
