You always buy fossil fuels with an EV, not directly but you do. When you stop at the plaza for a quick super charge there’s no way to tell where is the energy sourced from, it could very well be from a diesel generator a few miles down the road. The value is in all the parts found in an ICE that need servicing or replacement that you don’t have in an EV. With an EV you basically need tires and maybe brakes once every 8-10 years, no oil and fluids, no oil or engine filters, water pumps, spark plugs, valves, seals, etc etc
