I would have thought the solution to drought and water shortages would be to desalinate and reduce water wasted in order to fix the problem. Using a “mix of technologies” is ignoring the problem and trying to work around it instead of fixing it. And given that clearly having extra capacity that you don’t need at any given point in time just in case things go wrong is likely extremely expensive, I don’t really see the incentive. Frankly, even a really simple stupid question: what do you do with solar and/or wind power when it is dark and/or not windy? In other words, those solutions would still not be sufficient to replace nuclear during heat and drought, instead, you would need storage, which could store power from any source, but fixing the root causes of issues with nuclear power would seem more rational to me
