TASK 2: Scan the passage and write down the advantage (s) and disadvantage (s) of each alternative source of energy.

Sources of energy Advantages) Disadvantages)

Another alternative source of energy is geothermal heat,

which comes from deep inside the earth Scientists use this heat to make energy However, this energy is available only in

a few places in the world

It’s plentiful It can be very

dangerous

Paragraph 3

The wind turns windmills and moves sailboats It is a clean

source of energy, and there is lots of it Unfortunately, if the wind does not blow, there is no wind energy When water

moves from a high place to a lower place, it makes energy This energy is used to create electricity Water power

gives energy without pollution However, people have to

build dams to use this energy And dams cost a lot of

money, so water energy is expensive

If the wind does not blows, there is no wind energy.

It’s clean, expensive

Paragraph 4

…The sun releases a large amount of energy every day

This energy can be changed into electricity Many countries

use solar energy for every day life Solar panels on the

roofs of houses can create enough energy to heat or cool

an entire house Solar energy is not only plentiful and

infinite but also clean and safe

Sources of

solar energy plentiful, infinite,

clean and safe It’s only possible during the day

Sources of

energy Advantage (s) Disadvantage (s)

Nuclear power It’s plentiful It can be very

dangerous

Solar energy plentiful, infinite,

clean and safe

It’s only possible during the day

Water power It’s clean, plentiful,

infinite If the wind does not blows, there is no

wind energy.

Wind power It’s clean, plentiful,
