This is more of an economic\engineering problem than something that will take a revolution.
It's part of the reason why it also can't be done in desperation, it's just something that can't be done quickly, and it takes massive up-front investment.
Ironically, that would be the perfect fit with the needs of the muh climate change people, however those tend to have a massive overlap with the nuclear hating ideological greens, so overall they would rather push wind&sun tech no matter the cost and technological issues yet to be solved, and reliant on outright nonexistent mass scale energy storage technology it needs as support if it is to become more than a mere fraction of a developed country's energy grid.
