Good with RR, but I think they need to be looking at NASA
Kilopower too. It doesn't just do for Mars.
As for wind, the biggest thing is not enough storage. Wind power often turns negative on price because they are supplying more power than the market wants. The market is designed such that oversupply reduces the target price until sufficient oversupply turns it negative.
This is why I'm talking about targetted charging of EV's. If EV's are sitting waiting for prices to drop, they will consume all this oversupply. Once that is in place, the number of wind turbines sitting idle will drop dramatically because whatever they produce will be of value. Today they stop the turbines because it is, quite literally, costing them money to push power into the grid.
It is also a good fit with wind because offshore wind is normally strongest in the early morning and late evening.
But it will only work as a whole picture. Nuclear, Wind, Solar, Hydro, Geothermal, Biomass. Emergency peak will need to be some gas and some battery. Over time storage will grow. EV vehicles, cars and trucks, are a good storage medium as well as gigawatt battery, compressed air, H2, mechanical "towers". Storage is a big thing in research right now.
The thing is if we keep waiting for things to be "just right" they never will be. Because it won't pay. If we force the issue it makes worse in the short term but significantly better in the long term.
