Major appliance

[citation needed] While some of these brand names persist to the present day, even if only as licensed use of old popular brand names, today many major appliances are manufactured by companies or divisions of companies that specialize in particular appliances.

Current energy-efficient refrigerators, for example, use 40 percent less energy than conventional models did in 2001.

[3] According to a 2009 study from McKinsey & Company the replacement of old appliances is one of the most efficient global measures to reduce emissions of greenhouse gases.

[4] Modern power management systems also reduce energy usage by idle appliances by turning them off or putting them into a low-energy mode after a certain time.

An energy-efficient dishwasher, on the other hand, uses more energy during the late evening when people do their dishes.
