People want to act like there's a simple solution but anyone whose analysed the situation closely enough realizes that climate change is already locked in and renewable technology is not a good enough replacement given the power output and resource wastage. There is no way to even reduce energy demand since any reduction from one entity will be made up for by another entity, nobody has any desire for meaningful degrowth. Now that we have AI just watch us spin up nuclear reactor after reactor, drinking the ocean, and leaving every beach bare for the sake of 'progress'.
Society is already collapsing into violence and BOE is a couple years away if we're lucky. There is a reason I don't bother investing in retirement. It's a tragedy and people are in denial.
