Why is forced induction always mechanical?

I'm confused if your restricting flow via a turbine wouldn't that take power away from the engine? Or are you just creating energy from nothing?
I was under the impression that if you were to take energy from something and use it that you could not replace it with the same amount of energy.
For example a turbine spinning from exhaust gases, yes it will blow by but you are restricting flow which will impede power.
Hmmm maybe I'm wrong.

I would like to see the following on a normally aspirated car:
Dyno test #1 run a normally aspirated car with a turbo on the exhaust and the boost going into a closed chamber; then you would see the amount of power lost to the exhaust restriction under boost.
Dyno test #2 would be the same car (turbo now removed) with a blower mounted and the boost going into a closed chamber for a comparison.
I think the turbo would loose less power in this test than a blower, but there would have to be a measurable amount of power loss for each.
Updated:
Only nitrous is a "free lunch", but only because the gas was already compressed when added to the car.
And you pay for that lunch when filling the bottle!
