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


2. Read the text and check: (Ex. 2 / p. 44)

1. What are the main sources of energy in
Viet Nam?

2, What types of energy sources will be
used in the future?


3. Match the verbs with the nouns: (Ex. 3a / p. 44)

1. CREATE

A. MACHINERY

2. DRIVE

B. TURBINES

3.
GENERATE

C. ENERGY

4. TURN

D. HOUSES

5. HEAT

E. ELECTRICITY


b.Answer 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?
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?
5. What does the professor think VietNam will use
more in the future


• 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?

Hydro power 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 power and we
use then instead of non-renewable sources.


4.What types of energy does Vienam use
most?
We use non-renewable source of energy
the most but we are increasingly using
hydro power
5. What does the professor think VietNam will
use more in the future
He think VietNam we use the wind and the
sun as althernative sources of energy in the
future.


Ask and answer about adantages and
disadvantages of energy sources.
A: What type of energy is oil?
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.

Talk about the advantages and disadvantages of
each type of energy source
example
• Hydro power is a renewable source of
energy because it come from water. It is
cheap and plentiful. Unfortunately,
dams can only be built in certain areas.
