30% is the efficiency of the energy in fuel being turned into work.
You need to consider the efficiency of the power generation, power lines, battery and then the electric motor. Any other comparison is misleading.
- kalleboo 8y agoAnd gasoline has efficiency of exploring, pumping, refining and transferring it (tankers, pipelines, trucks to the gas station)
- blake1 8y agoCorrect that his is thermal efficiency, and I apologize for not breaking into out earlier. An ICE is ~20% efficient. A combined cycle gas turbine is ~60% efficient, transmission systems ~98%, LiIon ~99%, motors around 85-90%. The first is thermal, the rest are electrical. Well-to-wheel this is about 50%. My point was just that you really do get a large efficiency improvement (50 - 20 = 30) by electrifying cars. Climate argument aside, energy is simply being wasted.
