Opportunities and recommendations for reducing the energy consumption of consumer electronics products

摘要: Over the past few years entire new categories of consumer electronics products including DVD players, TiVo recorders, broadband modems, and large high definition TVs have entered market place. While these provide features consumers value, they consume considerable quantities electricity. Residential electricity use by has essentially doubled over decade, is now responsible for up to 15% household use. Unlike white goods, (i.e. refrigerators clothes washers) which time made dramatic reductions in their annual energy use, most classes more power than ones are replacing. Part reason this category's escalating that efficiency typically not a consideration during manufacturer's design process. For example, TV set top boxes used receive decode cable or satellite signals operate at full levels middle night even though user watching recording show. other product such as computers, periods extended inactivity been successfully reduced, but little progress address significant when being operated. In paper, we summarize work Natural Resources Defense Council (NRDC) Ecos Consulting performed assess consumption selected products. Per our analysis, if all today's TVs, (STBs) were meet minimum requirements recommended NRDC/Ecos, combined would drop 25%. This effect preventing need seven (500 MW) plants eliminates emission approximately 22 million tons/yr carbon dioxide, key global warming pollutant.
