Trang 7Dear 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.

Trang 10Answer the questions:
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?
5 What does the professor think Vietnam will use more in the future?
3 Why do you think the wind and the sun are
called alternative sources of energy?
4.What types of energy does Vienam use most?
Trang 11What is your favourite
source of energy?
Trang 12How many types of energy sources are mentioned in the text? What are they?
Two, they are renewable and
non-renewable.
Trang 13What are the disadvantages of hydro and nuclear power?
Hydro power is limited because dams cannot be built in certain areas Nuclear power is
dangerous.
Trang 14Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use them instead of non-renewable sources to get electricity we need

Trang 16What does the professor think Vietnam will use more in the future?
He thinks Vietnam will use the wind and
the sun as alternative sources of energy in the future
Trang 17What types of energy does Vietnam use most?
We use non-renewable sources of energy the most but we are increasingly using hydro power.

B: It is non-renewable source of energy, because it can not easily be replaced.
A: What are its advantages and disadvantages?
B: It can be used to power machinery , but it also pollutes the environment.
Oil is a non-renewable source of energy because it can not easily be replaced It can be used to power machinery, but
it also pollutes the environment
Trang 25Hydro power is a renewable source of energy because it comes from water It is
cheap and plentiful Unfortunately, dams can only be built in certain areas.
