1. Work in pairs. Discuss the following questions.
1. What are the main sources of energy in Viet Nam?
2. What type of energy sources will be used in the future?
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.
Task 3. a. Match the verbs with the nouns.
b. Answer the questions
1. How many types of energy sources are mentioned in the text? What are they?
Two. They are renewable and non-renewable.
2. What are the disadvantages of hydro and nuclear power?
Hydropower is limited because dams can not be built in certain areas. Nuclear power is dangerous.
3. Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of energy and we use them instead of non-renewable sources.
4. What types of energy does Viet Nam use most?
We use non-renewable sources of energy the most but we are increasingly using hydropower.
5. What does the professor think Viet Nam will use more in the future?
He thinks Vietnam will use the wind and the sun as alternative sources of energy in the future.
II. Skeaking:
Task 4. Work in pairs. Ask and answer questions about the advantages and disadvantages of each type of energy sources.
Example:
A: What type of energy is oil?

B: It is a non-renewable source of energy, because it cannot easily be replaced.

A: What are its advantages and disadvantages?

B: It can be used to power machinery, but it also pollutes the environment.
