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.

KW says how much power is used each second. If a device uses 1kw and is turned on for 1 hour, it has used 1kwh. When you turn on the same device for a half hour it has used 0,5kwh.
Kw can be compared to the amount of water flowing out of the crane each second. But you are charged per the netto amount of water used, kWh can be compared to liters in this example.
