Appliance Power Meters
These Kill-A-Watt products are great for analyzing which appliances are driving your electric bill. Just plug a Kill-A-Watt into the outlet then plug the appliance into the Kill-A-Watt. Wait a couple of days since some appliances run in cycles. Then read the Kill-A-Watt. It will tell you how many kilowatt-hours of electricity the appliance uses so you can decide to unplug it or replace it with a more efficient unit. It’s the best tool available for determining your phantom load – the appliances consuming electricity even when they’re not in use. That could be 15% to 20% of your bill!
