AI-generating images takes, like, zero resources. Think about it. My computer uses very little energy. It couldn't even heat my room if I ran it constantly (I accidentally tried by forgetting to turn on the heater). It can create an image in 20 seconds. There is no magic in AI that increases its wattage somehow. Also, I don't know if you noticed yet, but computers don't have a water input plug. Using a dishwasher once uses more electricity than generating thousands of images, and more water than infinite images.
