The deployment of solar is growing exponentially, with its total capacity doubling roughly every three years. Wind is growing at a similar rate. Renewables currently already account for 30% of the global electricity production, and we're seeing projections of over 45% in 2030.
Assuming the projected 2025-2030 installation speed is realistic and flattens out - bit "if", but not completely unrealistic - that means we'd be looking at 75% renewables in 2040 and 90% renewables in 2045.
Nuclear reactors take 15 to 20 years to build, and it'd take an additional year or 5-10 to scale up construction capacity. If we go all-out on nuclear now, that means significant nuclear power starts coming online in 20-25 years - so 2045-2050. At that point there is no more renewables gap left to bridge. There might be a small niche left for it if there is going to be essentially zero innovation in storage and short-term peaker plants, but who's going to bet billions on that?
Nuclear would've been nice if we built massive amounts of it 30 years ago, but we didn't. But starting a large-scale nuclear rollout in 2025? It just doesn't make sense.
