Actually cars can use concentrated solar plants and wind turbines. They are called batteries.
All the moving parts need oil, and vegetable oil won't work, they tried that in labs already. Also plastics need oil.
Miniscule compared to running a gas combustion engine.
Have you ever worked with engines, electric engines actually need just as much oil. The amount of oil a car "sprays" onto its engine is more than the oil required to make the fuel the combustion engine requires to run. Oil used for lubrication is pure oil and condensed, but when it's converted into fuel it is diluted and loosened to make it more combustible.
