The problem is that we can’t store electricity on an industrial scale. It must be made “to order“.
Solar or Wind is nice, but can’t meet power demand 24 hours a day. Nuclear can! And yes, it is nice to feed solar electricity back to the grid during the day, and to buy it back at night when we actually need the lights. But who is producing that electricity then? 20% Nukes, 1% from Wind and the rest … still fossil fuel.
Also energy must be produced close to the consumer. And it may not be the sunniest or windiest place. It should also be noted that even as the world’s temperature is changing, and the average wind speed is decreasing.
