40% of all electricity used to power home electronics is consumed while the products are turned off. This comes directly from the Energy Star website. While most electronics are constantly drawing power to run things like clock displays, Energy Star certified electronics use up to 50% less energy to perform these same functions.
So how do you know what electronics carry the Energy Star certification? If you are shopping in a store, the Energy Star logo will be front and center. If shopping online however, depending on where you shop, this may not be the case. By going to the Energy Star website, one can pick a specific electronics category and find qualified televisions, cordless phones and DVD products just to name a few. If every average home were to take this simple step when replacing obsolete electronics, it would save the green house gas emission equivalent of taking 3 million cars off the road.
The Energy Star program also offers special rebates and discounts as incentives. A list of these can be found here.
