Many here won’t like this, but I foresee that eventually solar and other power sources combined with domicile battery storage will be normal. There will then be extra power available that can be used for desalinization, vastly reducing the worldwide water shortage and turning desserts into highly productive farmland.
This assumes we are delivered from hell-bent depopulation overlords.
The problem is the rich and powerful don’t want the peons to go off the grid.
Solar power could be a ticket to true energy independence at some point—one home at a time.
