In Western countries, electricity, gas, and water are not luxuries but necessities . Companies now realize that consumers want products that will not only work effectively but also save money.
For most North American households , lightings accounts for 10 percent to 15 percent of the electricity bill. However , this amount can be reduced by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a quarter of the electricity of standard bulbs and last eight times longer . Therefore consumers can save about US $7 to US $ 21 per bulb.
In Europe , there is a labeling scheme for refrigerators, freezers , washing machines and tumble dryers . The label tells the consumers how much energy efficiency each model has , compared with other appliances in the same category .
Ultimately , these innovations will save money as well as conserve the Earth`s resources.
