    We had a scam in our city where our electric buses were being charged by Diesel Generators.

      Which in general is a more efficient way to use the diesel than if it was in an engine. However I’m not sure in this case, as I don’t know how efficient a generator would be compared to how ridiculously efficient a modern engine is. But electric engines outclass anything out there when it comes using energy.

        if you rip out an engene from a car, then you can operate it at its most efficient rpm all the time, instead of when you happen to cross the right rpm on the right gear. So an engine powering a generator can almost always be more efficient than in a car.

        This is not taking the losses in the electrical system when using the generated power in a moter to make the car move. But in a lot of cases, you still come out ahead

        Given the fact that India is the most polluted country in every single metric and one of the most corrupt, doesn’t make me think the generators they used were at all efficient lol.
