All renewables require *storage*. Storage is more than just batteries. How are you unable to comprehend the point I was making?
Let me try to explain this simply: wind blows a lot at night when sun doesn’t shine. So we need fewer batteries if we have wind and solar than if we just have solar. Do you understand now? Continuing to focus on adding just one extra power source, wind, leads to a reduction in storage requirements of about 40 to 60%. You also dramatically cut the duration of energy deficits and the frequency of deep shortages.
Adding just one other form of energy storage, eg pumped hydro, cuts total system storage costs by hundreds of billions more, because it’s about one third to one tenth the cost of lithium battery storage.
It’s just a nonsense to talk about lithium and solar only.
