Actually better than that: I already have the batteries and the inverter and just need to get some solar panels to install (next year sometime) and then it will run almost completely on locally produced renewable energy.
Right now it is still on local grid power, but that is mostly geothermal and wind (at least 60% on average).
Nice! Just out of curiosity: is there currently anyway to prove the use of renewable electricity to the public without revealing sensitive personal data?
