I remember seeing somewhere a multi channel current sensor.
One could wire it into one's power panel easily because it
required only passing a breakers hot wire through a given
toroidial current transformer.
Strikes me that would be a fast way to determine which
circuits were responsible for what fraction of power consumed.
It would be rough and ready because I can't recall if it had
power factor correction or even if it determined voltage to
arrive at wattage.
Beauty part is that it would allow one to calculate consumption
for hardwired loads like HVAC as well as loads connected to
outlets.

Exactly! if you are casting around for a way to save power expense, look
first at things that are running most of the time; forget things that are rarely
used. In your kitchen, it would do you little good to have the world's most
efficient toaster, but your refrigerator may be the cause of a significant
portion of your electric bill. On which should you invest your time/money?
