Came to say this. I would add that "powered by electric" also typically means that power was generated at an industrial-scale facility and so is likely inherently more efficient than on-site generation. Powering a vehicle with electricity generated from diesel is (or can be upgraded to be, over time) more efficient than powering the same vehicles using diesel powertrains.
