Read the text, and mark the sentences true (T), or false (F).
In Australia it is now illegal to use traditional light bulbs. The whole country is changing to low energy bulbs for their lights. This will reduce the amount of energy that each home uses and will obviously be better for the environment. And Australia is not the only country doing this. Will your country be next?
So, what are the advantages and disadvantages of using the new low energy bulbs? Of course, the main advantage is for the environment. If all houses in Viet Nam used these bulbs, the effects on the environment would be the same as taking three quarters of a million cars off the road. Cost is another advantage. If we changed all the bulbs in our houses, we could cut our energy bills by fifty percent.
There are a few disadvantages, however. The light that these bulbs give is not exactly the same as light from traditional bulbs. It’s colder and whiter. Some people don’t like it very much. Also, the light doesn’t come on immediately. After switching on the light, you have to wait a short time. Another disadvantage for some people is that at the moment you can’t make these bulbs give a stronger or weaker light by using a special switch. But scientists say this will soon be possible.
