Suggested answer
Sources of energy
Advantage(s) Disadvantage(s) We use it
to
Nuclear energy unlimited Can be
dangerous
Provide electricity Geothermal
heat
available Only possible in
some places Solar energy Plentiful,
clean, infinite, safe
Only possible during the day time
Provide electricity, heat and cool the entire house Wind power Clean &
unlimited
No wind no energy
Turn windmill and move sailboats Water power Clean &
unlimited expensive Create electricity
Task2: Go through the chart once more times and answer the questions.
1 Why are the above sources of energy chosen to replace fossil fuels?
2 Which is the most potential?
Suggested answer
1 Because they are not only unlimited, available but also clean and safe to the environment
2 I think solar energy is the most potential (has the most potential) because it can be produce at most houses in all the parts of the world / can be popular to many households

2 Is it limited or unlimited? What should we do to be sure that we can continue to use it in the future?
Task1: Read the sentences in the box and tick if these facts are advantages or disadvantages
Suggested answer
Task2: Work in pairs to make short exchange about the advantages and disadvantages of using each alternative source of energy Using the suggestions from Task1
*Useful Expressions:
I think that……
Why do you think / believe so?
It is …… However,………
*Model:
T: More and more people worry about the shortage of fossil fuels Ss: That’s true and I think that wind power can be an alternative source of energy
T: Why do you think so?
S: Because our major source of energy is running out while the wind
is abundant and unlimited
T: I know it is also clean and safe to the environment However, it is not available when there is no wind
Taks3: Work in groups to express your belief on the increasing use of alternative source in the future, using the ideas from task2:
Model:
A: I think that more and more people will use the solar energy
B: Why do you think so?
A: Because it’s available, unlimited and easy to use
C: But it’s expensive and we can only have it at specific time of the year
A: I hope that the progress of science and technology will help to overcome this problem
B: That’s right and then we don’t have to worry about the shortage of energy
C: And our life will be more comfortable with cheap simple devices
