UNIT 11: SOURCES OF ENERGY
FOSSIL FUELS
Are fossil fuels limited or unlimited?
- They are limited.
What should we do if fossil fuels ended / were exhausted?
- We should find out some new sources of energy to replace fossil fuels.
We use _______ to cook.
SOURCES OF ENERGY
WIND POWER
What source of energy is in each picture below?
WATER POWER
What source of energy is in each picture below?
NUCLEAR POWER
What source of energy is in each picture below?
SOLAR ENERGY
What source of energy is in each picture below?
GEOTHERMAL HEAT
What source of energy is in each picture below?
WATER POWER
WIND POWER
GEOTHERMAL HEAT
NUCLEAR POWER
SOLAR ENERGY
Wind power, water power, nuclear power, solar energy and
geothermal heat are alternative sources of energy.
Are these alternative sources of energy limited or unlimited?
They are unlimited / infinite.
Exhausted (a): completely ended
Infinite (a) = unlimited (a)
Energy (n) = power
Alternative (a)
e.g: Wind power, water power, … are alternative sources
of energy.
Wind power (n)
Water power (n)
Nuclear power (n)
Solar energy (n)
Geothermal heat (n)
Activity 2: Listen and repeat.
Act.3: Fill in each gap with one of the words below.
Fossil fuels will be __________ due to the rapid increase of power demands.
Solar energy is not only plentiful and _________ but also clean and safe.
Scientists are searching for ___________ fuels, such as the energy of the sun.
_______________ is a source of energy coming from deep inside the earth.

Act 4: Decide whether the statements are True (T) or False (F).
T / F
1. Our major source of energy comes from fossil fuels.
2. We needn’t develop and use alternative sources of energy
because fossil fuels will be infinite.
3. There are five sources of energy mentioned in the text.
4. Geothermal heat is available in many countries in the world.
5. Nuclear energy, water power and solar energy are useful
because they can create electricity.
6. Building dams to use water power doesn’t cost much money.
Act 5: Look at the picture and talk about the advantage(s) and
disadvantage(s) of each alternative source of energy.
WATER POWER
WIND POWER
GEOTHERMAL HEAT
NUCLEAR POWER
SOLAR ENERGY
Unlimited
Can be dangerous
Plentiful, clean, infinite, and safe
Only possible during
the day time
Clean & unlimited
Expensive
Clean & unlimited
No wind → no energy
Available
Only possible in few places
Act 6: Complete the summary of the reading passage by filling each blank with a suitable word from the box.
We need energy to live and work. Our major source of (1) _______ is oil. Oil is (2) _______ kind of fossil fuel. The amount of fossil (3) ________ in the world is (4) _________. Therefore, we must save it, and at the same time, we must find new sources of energy. Geothermal heat and nuclear power are (5) __________ sources of energy. They can give us electricity. Other alternative (6) _________ are the sun, waves and water. These sources are not only (7)__________ and available but also clean and safe for the (8) ____________ . People should develop and use them more and more in the future.
