The unforced error was/is not building out solar/wind/battery storage etc.

Instead they just added a tax for every citizen to pay on electricity and KEEP promoting coal.

Also WHY don't counties/cities own any solar/wind power stations to increase independence and lower long-term cost ?

Instead they sell out to companies or rich investors instead and those get subsidized.

Having a powerwall that can feed your local core infrastructure (hospital, water treatment, schools, etc) and then solar to charge the powerwall would mean you could isolate yourself from high spots prices for electricity.

With your own local powerwall, local grid tie will charge local capacity and be ransomed by the utility.
