That statement compares the one set of vehicles to another. It is using “batteries and electricity” to identify one set and “internal combustion” to identify another but it seems to be talking about the whole vehicle. In that context, EVs are massively more efficient in terms of energy used to travel than ICEVs are. Energy storage capacity and density are a different question.
