Home Equipment Cost of Operation

One of the easiest ways to reduce energy consumption is to get in the habit of turning things off when you finish using them.

Power fiction and facts

Fiction: Turning things on and off uses more energy.
Fact: Turning off an appliance is more efficient than leaving it on. While an extra surge of electricity flows when you turn on an electrical device, this surge is brief and uses very little extra power. Even computers can be safely turned off when you are not using them.

Some appliances use small amounts of electricity, but because we don't unplug them, they are using power 24 hours a day everyday and costing more than we realize. Any appliance with a clock or remote control function is "on" all the time.
