As a counter point, fission power did not really get cheaper once the initial difficulties were worked out. They are still highly complex machines that require a lot of engineering, custom parts and precision manufacturing. The same is true for fusion reactors, we still don’t have the technology to build one that actually produces power.
By comparison, solar and wind are pretty low-tech, so it’s easier to reduce cost by scaling up production and using automation.
Here’s hoping Sodium batteries provide some effective respite for that in the near future.
Yes, I have my hopes up for that one as well. Lithium-Ion was never meant to be cheap, it only got more affordable due to the massive scale of production, but it still uses expensive chemistry. If we could apply the same scale of production to a battery technology that uses cheaper materials and maybe less complicated processes, it would be a huge win.
