Which appliance in my home uses the most electric?

Ever wonder how much it costs to leave your air conditioner on all day when you’re at work? Or how much to leave that space heater on the basement? The Belkin Conserve Insight Energy Cost Monitor can tell you that, but it does more. It helps you measure the true impact of your energy use on your utility bill - and the environment. Just plug in any one device to find out how much energy it uses -- including watts, cost of operation, and the amount of carbon dioxide (CO2) emissions. See exactly how much electricity is used by devices like computers, televisions, kitchen appliances, etc. The monitor also shows the carbon dioxide emissions produced as a byproduct of your electricity usage. It can also measure "vampire" power, the power an appliance uses when it's off! These days many appliances never really go truly off. Installation is so easy, Unplug the appliance and plug in the Energy Cost Monitor. Then the appliance gets plugged into the device. You do need to make one setting when you first use the device. You need to tell it how much you pay per Kwh for electric. Don’t worry, that figure is printed right on your electric bill. Under $30.
