Exactly! With a turbocharger, the energy comes from exhaust heat. It's energy that would otherwise be lost out the tailpipe. With a supercharger, the energy comes from the engine, robbing power that would otherwise propel the car, and ultimately reducing fuel efficiency.

NO! That's the fundamental difference between a turbocharger and a supercharger. The turbo uses energy from waste heat, the supercharger takes energy from the engine.
