Seems to me that, now that both transportation and grid management is pouring bucketloads of money into energy storage technology, they'll just continue to improve and come down.
I mean, just as some countries are hitting 50%+ of renewables, and the variability is becoming a significant challenge, we're also starting to see a lot of EVs entering the market. I've got a car charging in my garage right now that my electricity provider can start and stop charging based on electricity prices. I can easily delay charging for 2-3 days if need be.
Seems to me that everything is coming together for a fully renewable solution. And this is probably what smaller island nations and such will want to standardize on anyway. It'll be the default for most areas.
Not that I mind nuclear.. just not sure where it'll fit in in the future. Just used in some key industrial areas maybe?
Nuclear submarines, and that is about it.
Desalinization?
May even in a generation or two. I doubt I'll see it in my lifetime though.
Reactors might also work for ships. A super reliable small reactor that doesn't require much support personnel might be option for powering cargo ships.
If we look at a long enough timeline, there really shouldn't be much change. The replacement of coal and gas plants would be with much cheaper renewable but also with higher cost nuclear. The average should land near the old price. What we observe is that the renewables have a head start compared to nuclear adoption so it seems like prices are higher because our minds are only remembering the recent price drops compared to the true legacy prices.
