The common on the street definition of power is often the same as energy.
I was dismayed when an episode of the Magic School Bus defined power as
energy. I suspect they are still using that episode. It really would not
hurt to say that the power is the energy put into the thing each second.
The difference between the two words is actually quite exact in trade and
science. So starting to make the distinction early can be helpful, even if
it is not fully understood.
