Hmm, you call yourself "joule" and use BTUs and kW-hrs in a post on confusing energy units. How perfect is that?!?
Ho, Ho!
It's just a matter of convention that's all. In the US at least, the energy content of fuels is usually given in BTUs (per unit weight or volume), whereas the charge-holding capacity of a large battery is usually given in kilowatt-hours.
But if one is actually doing energy calculations, then of course it should all be in the same units, such as joules.
No, stick to your guns. If you measure heat & electricity with the same units you create the confusion we've been talking about.
