Energy-saving bulbs should be use to save electricity In Western countries electricity, gas, and water are necessaries North American and European countries are interested in saving money and natural resources Labeling schemes help save energy North American and European countries are interested in saving money and natural resources b) Answer the questions What are Western consumers interested in? What can we to spend less on lighting? What is the purpose of the labeling scheme? Mrs Jones uses only ordinary bulbs and she pays US$8 for lighting How much will she pay if she uses energy-saving bulbs instead? Why should we save energy? What are Western consumers interested in?

We can replace an ordinary 100 watt light bulbs by using saving-energy bulbs What is the purpose of the labeling scheme? The purpose of the labeling scheme is to tell the consumers how energy efficiency each model has Mrs Jones uses only ordinary bulbs and she pays US$8 for lighting How much will she pay if she uses energy-saving bulbs instead? She will pay US$ Why should we save energy? Because we can save money as well as conserve the resources *Discussion: What should we to save electricity and natural resources ?
