Find Which Appliances Use the Most Energy

Smarthome offers a variety of power/energy meters to suit the needs of the average home owner to a master electrician. The basic idea behind using a meter is to find out how much energy is being consumed by appliances such as lamps, computers and entertainment equipment. This will identify the real power guzzlers so you can find ways to start reducing the use of costly appliances, which will help save money on your electricity bill and helps to preserve the environment. Each of the meters available at operates in same general fashion by installing in-line between any plug-in appliance and an outlet. While the same general information is read by each device: running time, Volts, Amps, Watts and Cumulative Kilowatt Hours (KWH), the real differences between each of the products are in the additional, various types of information and data that is acquired, analyzed and presented (see chart below). Most of this additional information and data isn’t necessary, after all the idea is simply to find out how much power appliances are using and find ways to cut back. As stated above, all of the meters offer the same basic readings...
