Task 1. The following statements list some advantages and disadvantages of  various sources of energy. Read and tick () the appropriate box  A ( for the 

advantages )  or  D (for the disadvantages ),  then compare the results with 

partner’s.

1.Fossil fuels will be exhausted within a relatively short

time

2.Geothermal heat is available only in the few place in

the world.

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.

If the wind doenn’t  blow,there is no  wind no energy.

It is expensive to built a dam

for hydroelectricity

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)

the wind 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,
