I was talking more about solar and wind installations, as well as battery tech and the low power consumption of modern tools.

20-30 years ago, if you wanted a stable ~3KW supply, you needed a generator and diesel/petrol. Lights, computers, power tools consumed an immense amount of power compared to today.

Now you can have one turbine and several solar panels coupled with a battery bank and you have the same supply of electricity without burning anything. It can power your whole house and everything you own for decades.

I'm a fan of decentralized energy production, though.
