> I wouldn't think of wind and solar as competition to fusion. Fusion power would have a different role in future electricity grids. Both would be complementing each other, rather than being a replacement. How would that work? Solar is very cheap. Nuclear is several times more expensive. Ergo, if the sun is shining at all the economically rational decision is to buy as much solar as you can. Same goes for wind. This means renewables will cut into nuclear, a lot. The whole "base load" ideal only works assuming nuclear is dirt cheap, but inflexible, and is supplemented with expensive but flexible sources for the times it's too slow moving. That would be the ideal scenario. The unfortunate thing is that nuclear isn't cheap, and renewables aren't expensive.
