Much of the avoided energy consumption will come from the switch to carbon-neutral district heating (rural households will switch from oil, natural gas, and electric heating to heat pumps and biomass burners).

Among the energy-saving options, two promising technology switches are the electrification of transportation (electric vehicles can be about four times as energy-efficient as standard fossil-fuel vehicles) and the use of electric-powered heat pumps to deliver winter heating and hot water (heat pumps can be four times as energy-efficient as standard heaters).

In addition, the U.S. has experienced an unseasonably mild winter, giving furnaces a welcome respite and their owners lower heating bills, making the higher payment at the pumps a little more palatable.
