No it took fuel, and released the potential energy from it.

So energy. A tank of diesel is a tank of energy.

I think you will find that "heat" is energy as far as anything (or one)
is concerned.

Yep.

A powers station takes energy, water, oil, or coal, burns the energy to

power, which turns the generator which produces energy, which goes down

No, power does not come into it. power

work.

It does come into it. A tank of diesel to intents is a tank of energy. It
is used to create power which charge the energy from one state (oil) to
another heat. It took power to do the state change.

It is not until you use the energy that you can ascertain the two
bits of information you need: How much energy was used (i.e. the amount
of work done), and how long did it take. Then you can calculate "power"

All the "power station" is doing (viewed as a black box) is changing
energy from one form to another.

And uses power to do it. So, power comes into the reckoning.

A boiler: The output is in "power". Yet the boiler just converts one energy
state (oil) into another (heat). Yet the output is rated in "power". It
takes power to do the state conversion.
