The compounding effects on this are going to be dramatic. Everyone who borrowed money at sub-5% rates and then saw retail electricity going up by 50% made a great decision.
Previously, worldwide supply expansion = increasing fuel costs in the global market
In a post-fuel / solar world, you can keep increasing supply capacity as long as you want. Which would upend a lot of assumptions about power. E.g. free or negative power cost at peak supply times, simply because people keep building capacity
The electricity price already turns negative in quite a few countries with larger shares of renewables at peak times, but isn't really being exploited right now due to the high capital cost and low usage for most things that need electricity.
Which is another way of asking "When will people stop consuming more power?"
Previously, we had finite energy resources that were limited by the fuel (oil, coal, gas) or regulation (nuclear).
Suddenly, there is no limit. You could build as much solar as you had panels + installers for.
Which really turns future energy on its head. Why not build more forever? And if there's excess, build more energy consumptive industry...
