Encouraging consumers to save energy has become a fairly common way for electric utilities to level peak-period loads and avoid building costly new power plants.(1)_______________________.As this winning refrigerator will likely be more expensive to manufacture than conventional models, the utility group intends to use the money to pay part of the cost of the mass-produced winning refrigerators so that they can be sold at a competitive price.Refrigerators use 25 to 30 percent of the average household's electricity.Refrigerators made 20 years ago consume some 1,500 to 1,800 kilowatt-hours annually.The new refrigerator would use 25 to 50 percent less electricity than will be required by Department of Energy standards, that is,about 900 kilowatt-hours.(2)_______________________.That would save the average owner up to 200 a year in electric bills over a 15-year old refrigerator.
Now,in the twist on the idea,a group of utilities is offering 25-30million dollors tho the manufacture comes up with the most efficience cost effect refrigerator.
The utilities group is hoping to find one use still less energy 300-500 kilowatt-hours
