Sources of Energy

B SPEAKING

1.Which source of energy is the most popular in our country?

2.Is it limited or unlimited?

3.What should we do to be sure that

we can continue to use it in the

future?

Answer the following questions

Task 1: Read the sentence in the box and tick if these facts are advantages and disadvantages:

3.If the wind does not blow, there is no wind energy.

4 Water power provides energy without pollution.

5.A nuclear reactor releases radiation which is

dangerous to the environment.

6 Solar energy is not only plentiful and unlimited but

also clean and safe.

7.It is expensive to built a dam for hydroelectricity.

Task 2: Work in pairs

Talk with your friend about the advantages and disadvantages of using each alternative sources of energy , using the suggestions from Task 1.

Why do you think so?

I think that wind

power can be an

alternative source of

energy

enormous, plentiful, available dangerous

clean and safe expensive

unlimited, renewable polluted

convenient limited, non-renewable cheap, simple devices/ technology harmful

exhausted

A: I think that can be an alternative sources

of energy.

B: Why do you think so?

A: Because our major sources of energy are running out while

Example :

wind power (1)

is abundant and unlimited (2)

it is also clean and safe to the environment.

(3)

it is not available when there is no wind.

(4) However,

B: I know

Make a conversation to express your belief on the increasing use of alternative sources in the future, using the ideas from Task 2.

Task 3: Work in groups

Student A: Give your suggestion of an alternative source of

a source of energy in the future.)

Student B: Ask A for the reason (Why do you think/believe so?)

Student A : Explain the reason (Because it is unlimited…… )

Student C: Say the disadvantage of that source (But it is

expensive and only available during… .)

Student D: Express his own opinion (I hope the progress of

science and technology/ will help overcome this problem… .)

Why/ think so?

because/ available, unlimited & easy to use

But /expensive and /specific time of the year

I hope that scientists will help/

overcome…

Cues: I think more and more people use (solar

power/ nuclear energy/ Geothermal heat/ wind power/ water power)

Why /think /believe so?

because/ available, unlimited & easy to use/ plentiful and infinite

But /expensive and /specific time of the year/ expensive to built a dam for

hydroelectricity

I hope that scientists/the progress of science and technology will help

overcome…
