How much hydro do appliances use

EnerGuide labels tell you how many kilowatt hours kWh of energy you can expect that model to use each year. This number is the expected annual energy consumption of the appliance in kWh. The lower the number, the higher the savings. The energy consumption indicator shows you how this model compares to others in its class.

The bar below the indicator gives the energy-efficiency range for the class. The further the indicator is to the left end of the scale, the better. This bar shows the energy consumption of the most and least efficient appliances in this class.

In this case, the most efficient comparable model uses kWh per year, while the least efficient uses kWh per year. Here's how to be a smarter appliance shopper in 10 seconds: first, make sure you are comparing models in the same class. Next, check the kWh number — lower is better.
