Read the passage and decide which statements are True (T) or False (F).
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, 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, 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 smoney as well as conserve the Earth's resources.
1. In Western countries, energy is cheap.
2. Consumers can save money by using energy-saving bulbs.
3. Labeling scheme is a good innovation which helps the European to save money and natural resources.
4. Ordinary 100-watt light bulbs use a quarter of the electricity of standard bulbs.
5. North American and European countries are interested in saving money and natural resources.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.
Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to
make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.
1.How many types of energy sources are mentioned in the text? What are they?
2.What are the disadvantages of hydro and nuclear power?
3.Why do you think the wind and the sun are called alternative sources of energy?
4.What types of energy does Viet Nam use most?
5.What does the professor think Viet Nam will use more in the future?
