Energy meters

Energy meters (also know as electricity monitors) are the best way for you to understand what is causing your electricity bill to be so high. Some energy monitors work by being plugged in between the power socket and an appliance to tell you what that particular appliance is costing you. Other electricity meters use a sensor on the electricity supply into the premises along with a wireless display, to tell you the total electricity being used. You can then walk around your property switching on and off electrical appliances and seeing the effect on your power consumption. Many, but not all, are capable of measuring consumption off a 3-phase supply if you buy an additional two sensors. 

Energy meters can show you the power being used (in Watts), the amount of carbon you are generating (your carbon footprint), or best of all, the cost of the electricity you are using. Using an electricity meter over time you can learn how to be more economical in your power consumption, and save yourself money.
