No. Why would anybody have an intuitive frame of reference for what a joule is.
This appliance uses 1 kilowatt, running it for an hour is a kilowatt hour. Easy.
*And I can't even find anything suggesting any countries meter electrical bills by the joule so ???
This appliance uses 1 kilowatt. Running it for 1 second uses 1 kJ. Easy.
Are you billed by the hour, or by the month?
By the kilowatt hour per month.
If you're talking about systems that generate and consume power measured in watts. Why would you then convert to joules so that you can say 'this generates ___ joules per hour' when you could just infer kwh from the nameplate wattage. It's an extra conversion for no reason.
Why would I care about "Joules per hour"? What matters is power (Watts), and total energy used (Joules). "Kilowatt hour per month" is just an awkward way of saying "Joules per month"
