It seems sort of nonsensical to project electric usage decline as we move from ICE to EV and from oil/gas heat to heat pump.

- Scarblac 3y agoIt's a decline in overall energy, presumably not in electricity.
- morsch 3y agoThis is final energy demand and thus presumably includes energy used for heating and transportation that's currently provided via fossil fuels. In fact, that's the point: electrical motors and heat pumps are more efficient, and the final energy demand is reduced. In other words, demand for electricity goes up, total energy demand goes down.
- steveBK123 3y agoThat makes more sense if we are talking total energy demand.
- mikeyouse 3y agoYeah - the original point was about a reduction in total energy demand, not electricity demand.
- gpm 3y agoThe ballpark number for EVs is that they are 4x more efficient than ICE cars AIUI. Harder to ball park heat pumps because it depends on the climate, but 4x is probably a reasonable guesstimate. At worse it's equal to burning things for heating (when it's too cold outside to use heat pumps, not sure that really happens in Britain), at best it's... some ridiculous factor better (when it's practically the same temperature outside and inside).
