Fifty percent of American electricity use is air conditioning. Air conditioning is great, but it's not needed half the time it's used. If you just want to cool a room open a window. Also, you can use a fan because it uses electricity, but not nearly as much as an air conditioner. Another big waste of electricity is lighting.
Lighting is twenty percent of American electricity use.
Most of that twenty percent is unneeded like sleeping with the lights on, having lights on in a zillion rooms, or just turning the lights on during the day. The other thirty percent is used for cooking, cleaning, and so on. If you just saved forty percent of the electricity you use in a year, that could save you around eight hundred forty dollars per year. That can be put forward to college tuition for your children, or it could just be more money in your pocket. These were just a few of the ways you could save electricity.
