While a power plant is more efficient than my car, transmission reduces that efficiency sigificantly (I think here in the UK transmission accounts for 40%-50% of usage, although I may be misremembering).
Does that affect the calculation at all?
EDIT: I was totally wrong - it's more like 7%. Still interested whether that affects the calculation, although it's much less likely to!
- Dylan16807 2y agoWikipedia says 7.7% distribution loss.
- robertlagrant 2y agoThat is a lot lower than I remember! I'll try and find my source for that. EDIT: I can't find that source, and I found a load of sources around 7%. Thanks for the correction.
- ZeroGravitas 2y agoYou might be recalling that 40-60% of the fossil fuel is wasted as heat when generating the electricity, before transmission. Since cars are more like 80% waste heat, it still works out better to generate the electricity and feed it to EVs.
