EVs (and heat pumps) do not require renewable grids to be more efficient than ICE cars (and gas boilers) They are sufficiently more efficient (roughly 4x) than even adding the 60% inefficiency of gas turbines and electricity transmission, charging losses etc. do not destroy their inherent efficiency advantage.
