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.

If you bike super hard, you might get 400w of output. This is the energy you are able to dump into biking every instant. It’s an instantaneous measure of how hard you are working. The very next second you might cool it a bit and drop to 300w.
If you bike really hard at 400w for an hour, then the cumulative energy you’ve output is 400Wh
