The economics are not there. Solar + batteries are much cheaper per watt today and still improving. Even better, the solar can come online instantly and expand while US nuclear takes twenty years to start generating any energy.

> Solar + batteries are much cheaper per watt today and still improving.

Are we still going to make the same error over and over again? The day China says "stop" the price per watts will explode, just like when Russia and Iran said "stop".

I'm a huge solar fan, but I don't see energy transition happening as quickly as I'd hoped 10 years ago, and what seems apparent now is that it will only happen when energy storage gets 10x cheaper, which is why companies like Form Energy developing iron-air batteries might be the catalyst. You also need grid-forming inverters that balance the loads since relying on hundreds of thousands of residences for grid-tie is a real engineering challenge.

I strongly agree. We _will_ get there with solar, wind, and batteries.

Eh, it looks like micro reactors are coming on line much faster these days.

Meh. Cheap seasonal batteries aren't a thing yet so for much of humanity solar + batteries just can't cover the same needs as other means of generation.
