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

radiators. The heat travelling to the rads in the pipes is now energy as

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

A powers station takes energy, water, oil, or coal, burns the energy to make
power, which turns the generator which produces energy, which goes down a

No, power does not come into it. power is a measure of the rate of doing
work. 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.
