Electrifying would mean switching a home’s heating system from a boiler to a heat pump and transitioning from gas- or diesel-fueled vehicles to electric vehicles. “If we install a whole bunch of new electric heating systems for homes and use more electric vehicles and electric water heaters, then we’re going to increase electricity demand a lot. But taking measures such as installing better insulation and air sealing, improving equipment efficiency, and coordinating the operation of the home’s electric devices could mitigate the costs of upgrading the grid. An example of boosting the efficiency of the home’s electric equipment would be using ground-source heat pumps instead of air-source heat pumps because the constant ground temperature reduces the energy needed to heat and cool homes. Coordinating the home’s electric device operation could mean adjusting when the home’s electric vehicle charges so that it doesn’t happen at the same time when the heat pump is in use.
