The size of the Hummer EV battery could efficiently operate a home if power is out. Will the hummer EV in case of a power outage power my home? I build Zero Energy Ready Homes. The homes I build are a pathway to reduce the carbon footprint. My Hummer Ev is due for Delivery on 10/3. I hope in the future I can continue this quest to reduce the carbon footprint with my new EV as a backup source of power to do away with dirty fuel-operated backup generators or a need for wall battery packs. The truck battery (212.7 kWH) would be my first choice !!! I hope we can make this happen !!!
