ELI5: What is the difference between KW and KWh?

Update: I am actually searching for really simple, intuitive ways to explain it. I have a background in engineering, but am struggling to explain why we "pay for kwh", and not kw (on our electricity bill) to someone who doesn't. I have tried in many ways but maybe I'm not giving the right examples or making the right comparisons. I am really searchig for a way to ELI5.

I often use the analogy with a water tap and a bucket. Power is best associated with how much you open the tap, while energy is how much the bucket is filled with water.

This way it's easy to figure out how you can have accumulated (or spent) a lot of energy even with very little power, because it also depends on time.

May not be 100% accurate but you get the idea. HTH.
