Solar power has finally passed the point where it saves more CO2 than it produces during construction.  (Wind power has not).   I'm hoping a southern club member will land-lease to produce solar energy to mine bitcoin we can give to our members.  Wrap all the expenses and income in a blockchain, and this could be the first community mining project everyone could stand behind.

What people do with their energy is their business, but if I lived at a lower latitude and could get free power, I wouldn't be using it to support a blockchain that misuses energy like bitcoin does.  Survival societies should implement a private blockchain today, and be ready to transfer bitcoin assets and the mining energy to these blockchains when things collapse.
