I got an email from my electric utility this summer, pointing out that I was using MASSIVELY more electricity than the same month last year. Like, roughly triple.

When I was at work every day, I had my HVAC on a pretty drastic setback; no sense cooling an empty house. I guess it worked pretty well! Because this year I was home all summer and despite not wearing pants most of the time, it still took a fair bit of power to keep things not-sweaty.
