I was in the same situation like this before. She always had everything going and left on 24/7 heaters were blasting as well. The bill was around 300 to 450. I moved out used one heater and my bill was only 15-70 being the highest. The funny part that’s just electric we had water paid by our building.
Game consoles use very small amounts of power these days—same with TVs. My electric bill usually sits between $50-$80 and I tend to use my stuff a lot. I even have a gaming PC. They just don’t use a lot of power. What will always run your bill up is heating/cooling. In some ways, the PC and consoles would have actually LOWERED your bill in cold weather
