Last month, our electricity bill ballooned and none of us could determine out why. Two of our roommates and I started going over everything, trying to understand what the problem was! It’s the middle of summer, so the utility bills here are generally pretty low. But not one of us has an air conditioning unit, there were no apparent suspects to speak of! First, my roommates and I looked at our fans. We all have these undeniably lovely, luxurious floor fans that actually deliver cooling air. So we looked up their specs online and tried to figure out how much wattage they consumed, and even with us running them all the time, the usage wasn’t enough to explain the bill spike. They’re still fans, so they barely pull that much wattage at all. My roommates and I walked the whole house to make sure none of the lights were being left on, especially in the garage, where the lights are often overlooked if someone is tired while taking out the trash. Still, there were no lights being left on. Finally, I printed out the digital bill in its entirety to compare it to last month’s. I was wondering if maybe the price per kilowatt had gone up and I hadn’t observed. However, that was not the case; the bill distinctly showed that the price had stayed the same, and we had simply used more electricity. My roommates and I didn’t figure this out until a one of us handed the mail off to our fourth roommate that included a small package. It was a part to the new supercomputer he had finished numerous weeks ago to play with his friends online. The new computer was so powerful it made the utility bill increase over fifty dollars.
