Have you ever heard of the Kill A Watt EZ from P3 International? It is a very handy tool that anyone can use to find out how much power your appliances are using. It will show you the operating cost of each appliance individually. You can also view the weekly, monthly, and yearly potential costs. All you have to do is plug the small box into a wall jack and then plug your appliance into it. It’s that simple! It’s an easy great way to pin point which items are costing you the most money in your home. We picked ours up at Lowe’s but you should be able to get them at any hardware store.
