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.

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.
