Mrs. Mi: What's the matter, Mrs. Ha?
Mrs. Ha: I'm worried about my most recent water bill. It's enormous.
Mrs. Mi: Let me see. 200,000 dong! You should reduce the amount of water your family uses.
Mrs. Ha: How do I do that?
Mrs. Mi: First of all, get a plumber to make sure there are no cracks in the pipes.
Mrs. Ha: I'll do that.
Mrs. Mi: Baths use twice as much water as showers, so I suggest taking showers. And remember to turn off the faucets. A dripping faucet can waste 500 liters of water a month.
Mrs. Ha: I see. Thank you.

In western country, 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 America households, lighting 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, freezer, 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.
