Although not every model of GE clothes washers is energy efficient, those branded with the Energy Star logo are. Every washer that meets or exceeds the federal guidelines for energy efficiency is awarded that distinction. Energy-efficient GE clothes washers include the GTWN7450HWW and GFWR4805FRR models.
Energy-efficient GE washers feature the following four characteristics: moisture sensors, larger capacity, longer agitation strokes and load-sensing adaptive fill. GE washers with a large capacity are capable of washing more laundry in less time, which results in energy savings. Sensors within these washers are able to detect the amount of dry clothes inside them, allowing the washers to use only the necessary amount of water and power. Longer agitation strokes allow the washers to turn over the clothes and use less water for each load.
As of 2015, washers branded with the Energy Star logo normally use 50 percent less energy and water than their energy-inefficient counterparts, while GE Energy Star washers use 64 percent less water and 75 percent less energy. The GE appliances products website features 20 Energy Star-qualified washer models as of February 2015. The cheapest model is the GTWN4250DWS, for which the suggested retail price is $650, while the most expensive model is the GTUN275GMWW, which is $1600.
