This is true. Though the electric batteries do have the advantage of having already paid the "thermodynamics tax". Some of the energy in gas will go towards heat losses; energy that cannot be converted to movement.

- iknowstuff 3y agoHeat pumps make it more efficient to convert the fuel to electricity at a big, efficient power plant, and then to heat, than to burn the fuel itself for heat in an internal combustion engine (or at home for that matter) It’s overall a net positive.
- mensetmanusman 3y agoYes, but note that this type of 'overall thinking' sometimes has interesting consequences. Eg overall globalization raises wages, but it decimated rural economies in the west and caused a lot of social harm leading to the rise of populism. The odometer shock that will start hitting low wage earners forced to migrate to EV may have less important but similarly surprising unintended consequences.
