Power so cheap that it did not have to be metered was the promise of Nuclear power but it got sidelined because of safety concerns. Given that climate change mandates a less polluting power source Nuclear power will get a new life which dictates that it become safe to operate. I predict that safety will increase over time. Even now there are experimental reactors that are fail-safe. It's only a matter of time before Nuclear reactors start to generate cheap safe energy. Here's a company that's working on it now: https://www.terrapower.com/about/

Also, solar power is making a large dent in our power needs.

It's a start but give it time.
