No amount of batteries can protect a solar/wind grid from an arbitrarily extended period of "bad" weather. It's like range anxiety in an electric car. If you have N days of battery storage and the sun doesn't shine for N+1 days, you're in trouble. Nuclear fission is the answer. Today there are 440 nuclear reactors operating in 32 countries. Nuclear fission is expensive up-front but once built the power plant can last 50 years (maybe 80, maybe more) and the uranium fuel is very cheap, perhaps 10% of the cost of running the plant. This is in stark contrast to natural gas, where the plant is less expensive to build but then fuel costs accumulate rapidly. And natural gas is a poor choice if you care about greenhouse gas emissions. Sam Altman owns a stake in Oklo, a small modular reactor company. Bill Gates has a huge stake in his TerraPower nuclear reactor company. Oracle announced that it is designing data centers with small modular nuclear reactors: https://news.ycombinator.com/item?id=41505514 https://news.ycombinator.com/item?id=41505514 In China, 5 reactors are being built every year. 11 more were announced a few weeks ago. You just don't hear about it... yet. Nuclear fission is safe, clean, secure, and reliable.
