It'll be interesting to see how everything develops but Japan has an absurd amount of offshore wind potential. Their country is set up perfectly to take advantage of it given their major cities are all up and down the coast, they're also ~100 miles from mainland Korea which has plenty of wind and solar potential as well.
There are geopolitical concerns to relying on your neighbors for energy transmission, but it's hard to think of any technical or financial reasons that would stop it. Given current learning rates and cost trends, utility solar will likely be under $0.01/kwh in just about every place on earth. Certainly within 15 years, likely within 10. When new-build nuclear is above $0.10/kwh and takes a decade to build, the delta buys you a ton of storage.
- jchw 4y agoI agree that it'll be interesting to see. A primarily-wind Japan would be cool if it could be done, and it seems like a win/win. I wonder if it still makes sense to keep nuclear energy around in the mix as a sort of backup, though. We've already got a ton of plants that could probably last more decades with proper maintenance to my understanding, and despite making up a small number of energy production facilities they make up a huge mix of the energy in the world, so it seems like it could be a solid backup plan in a primarily wind and solar world.
- mikeyouse 4y agoOh yeah, existing plants can be operated at very low cost -- if they're sited in safe locations, and certified / refurbished for extended use beyond their design life, it definitely makes sense to keep them running for as long as possible. If Japan overbuilds their wind resources while maintaining their nuclear fleet, they could send the nuclear electrons the other direction and power Korea with nuclear.
