alt Hacker NewsWind is a thing, batteries are a thing, hydro is a thing...
Maybe all that's still not going to cover you in all cases, but...I'm not anti-nuclear by any means, but my understanding is that the upfront costs are very high and take a long time to recoup even in the best of cases. If it's only used as a backup for when cheaper renewable energy can't be generated or bought I'm not sure if the economics will ever work out anymore.
There's a different between "a thing" and a complete system.
They're still expanding hydro in China because they can tell 2 million people to take a hike and there is nothing they can do about it. I remember reading about how the Glen Canyon dam was going to silt up in 40 years or so back in 1990 and... it did!
A real price for solar energy when you consider batteries for overnight/Dunkelflaut and overbuilding for winter could be 2-3x what people are quoting now... Right about in AP1000 territory.
And yeah, what will really happen is that energy markets will be built around the need of gas turbine peakers who will wind up making almost all the profit in electricity generation even if they are only making 1% of it. By 2050 renewables might be seen as a failed technology the way nuclear was circa 1990, but it might not matter much because India will have a heat event that causes a few million mass causalities and they might decide to use their nuclear weapons to put an end to the fossil fuel age.
