Friends of ours live in rural Utah where they’ve had a serious cold snap for a week with temperatures between 20 and 30 below zero every night.
Their water comes from a well, the power went out, and thus the pump house heater couldn’t run so the pump froze solid and may be damaged. They’ve not had water for a week now.
With solar power storing electricity in a battery, the pump heater would have operated. They have in fact installed solar, but a parts shortage meant they could hook it up to the house and pump.
They are moving full speed now to get the parts and say they are “looking forward to our new life with solar.” Wind power too.
