How does it make sense to compare renewable vs non-renewable energy sources? Where does that electric car's energy come from? Suppose the electric car's energy is solar. Then driving the electric car consumes zero barrels of oil, and so is infinitely more renewable than the petrol car. Or how efficient is the electric car at capturing available energy? Maybe the petrol car is 20% efficient at capturing available oil reserve energy. But the electric car is like 1e-30% efficient at capturing available solar output. Incomparable.
