Personally, I've invested ~500k EUR in a Portuguese Golden Visa fund invested in renewables (IRR is ~7-13%). Macro speaking, renewables investments keep hitting new records. I am convinced, and if you are not, I would strongly suggest consuming more data, because you appear to have a potential blind spot in your mental model on this topic.
Go and throw all your money into renewables stocks and ETFs if you’re so convinced.
I bet you’re not doing that because you realize that the industry isn’t doing well and it’s nuclear power nowadays where all the money goes.
