My electric company used to make an amazing little graph. So simple but it’s effective. It was temperature and electric cost per month on top of one another. Sometimes they’d correlate: higher temps = more air conditioning = matching increase in electric usage. BUT, sometimes they wouldn’t correlate at all and they’d collide with one another. When that happened, it usually traced to somebody in the house that got a new ‘thing’ they didn’t tell anybody about that was sucking up electricity. Or it would coincide with company that came to visit for a week or so. Or holidays. But it was powerful showing two things that only occasionally correlated but did not always do so.
