We don't have time to wait for a breakthrough in battery storage or carbon recapture. We have a solution now and it's nuclear power. It's a bit late for starting a nuclear programme now, but countries with current a nuclear power capacity (including Germany) should absolutely delay or cancel phasing it out until climate change is solved.
