Energy consumption appliances

After 1986, the CAFE and appliance standards in place resulted in stock turnovers to more efficient automobiles and appliances. However, the decline in energy consumption per dollar of GDP slowed appreciably and, between 1986 and 1997, the energy intensity trend remained rather flat. Other forces in the U.S. economy were pushing energy consumption higher, resulting in increases in the energy-intensity measure. 

Intelligent process control based on platinum temperature sensors and tailored electronics provides an effective method of improving both kitchen safety and the user friendliness of kitchen appliances, and also contributes to reducing energy consumption. 

As a consequence of recent technical developments as well as legal and policy requirements, overall energy consumption for domestic appliances in Europe is expected to fall gradually. The total energy consumption of washing machines, dryers and dishwashers is estimated to be around 60 TWh in Europe, equivalent... 

Another important application for plastics is thermal insulation. Without plastic insulation, major appliances would consume 30-50% more energy. From 1972 to 1995, the energy consumption of major appliances decreased by up to 40%, and energy efficiency increased 50-100% (19). 

U.S. energy consumption slowed down in the 1970s and 1980s, as manufacturers introduced more efficient appliances. Even so, by the late 1980s, Americans consumed more petroleum than Germany, Japan, France, Italy, Canada and the United Kingdom combined. 

Energy Guide Labels - The labeis piaced on appiiances to enable consumers to compare appliance energy efficiency and energy consumption under specified test conditions as required by the Federal Trade Commission. 

This issue is particularly severe for the household appliance industry, which has also been called upon over the past years to progressively reduce the energy consumption of their products. 

Refrigerators and freezers account for about 20% of the total electricity consumption of household appliances. For this reason the appliance industry is under pressure to improve the energy efficiency of their products to cope with the need to reduce carbon dioxide emissions, as recently mandated by the Kyoto Conference. This objective has to be achieved without penalising product performance. Several options to decrease the energy consumption are under evaluation, ranging from high efficiency compressors to the adoption of intelligent electronic devices [57, 58, 59]. 

Thanks to this, vacuum panel technology is becoming a technically viable and cost effective solution to the need to reduce energy consumption in household appliances and in commercial and industrial applications. To successfully achieve this target, additional efforts are necessary to further improve the component quality and reliability (foam, film and adsorbent), to optimise panel production and to reduce costs. 

Figure 9.5 I The graph shows the predicted impact on energy consumption resulting from the implementation of more efficient technologies for common household appliances.

Most energy consumption in homes (domestic use) is accounted for by major appliances. As older appliances wear out and are replaced with newer ones, improvements in energy efficiency help lower the overall energy consumption in the country—enough to offset the growth in the number of homes with appliances. 

On an individual basis each of us can play a significant role. Recycling, switching to more fuel-efficient cars, and using energy-efficient appliances, heaters, and air conditioners all would result in decreased energy consumption and less carbon dioxide being released into our atmosphere. 

In living room, electrical appliances are chosen as 6 times 60W bulb, a 25 inch (63.5 cm) Television, a CD/DVD player, a portable stereo, surrounding sound system and a mobile phone. Total electrical energy requirement of the appliances is 1135 Watts. Usage hours of the appliances and energy consumptions according to season and time options are shown in the tables C. 1 and C.2.
