Did you ever watch the show, “The Colony”, on Discovery channel? (Good concept; crap production value.)
People from varied backgrounds are placed into an urban survivalist scenario. After they secure some food and water, invariably they start to work on producing power. The solutions are ingenious, using materials at hand, they always come up with a power supply.
So, I think “powered tools” are here to stay, as they have been created and we will re-create them. The source of power will evolve.
For the record, I’m so dependent on electricity that even when the power goes out, and I know it… I’ll try to flip the light switch in the basement in my search for a flashlight with working batteries.
