Why don't you upgrade your Current Cost network with an Envi?
A monitor that identifies those energy hungry appliances.
The Current Cost display has been designed to assist you in stopping wastage, this doesn't mean stopping use - we want you to enjoy your appliance investments. But, if you are wasting energy, you are wasting money. The bar graph on the display should show virtually nothing during the night and if you are working it should show the same during the day, if it doesn't, maybe you are leaving something(s) on that could be turned off?
