Cutting the number down

A heat-pump water heater does the same job for roughly a third of the electricity, which is why it usually pays back faster than any other upgrade in the house.
Dropping the setpoint from 140 F to 120 F cuts standby losses and scalding risk at once.
An insulating blanket on an older tank pays for itself in a season; check the manufacturer's guidance first.
