The specification kilowatt hours per year tells you approximately how much electricity an appliance uses each year. A kilowatt hour (kWh) is a unit of measurement for electricity; you'll probably see kilowatt hours written on the electricity meter in your back yard or basement.
By comparing the kWh per year of different appliances, you can find more efficient models. A top-load washer might use 450 kWh per year, for example, while a more efficient front-load washer might use only 150 kWh per year. More efficient appliances can be better for the environment and help reduce your electricity bill.
