The Modified Energy Factor (MEF) considers energy used by the machine as well as the water heater for each cycle and by the dryer to remove the remaining moisture...the higher the MEF is the more efficient the washer is.
Energy Star requires that the WF be less than 8 and the MEF be higher than 1.72... to find out what your washer is or to find info on a new washer you can find the product criteria on the Energy Star website. And to see a table of products with their WF and MEF listed you can check out the Wash Wise website.
