My home computer batch processing prompts thru Stable Diffusion can generate and then nicely upscale images at at rate of about 1 every 5 seconds. Or 360 per half-hour. Which means a newly image on the display every day to look at for a year in just an half hour of computation. At about 300W of GPU + 120W of PC, that is 420W * 0.5hrs = 0.210kWhr. This is a rounding error on my monthly electric bill. About six cents. I've spent more energy than that likely just sitting and reading HackerNews this week.
