Unit 10: SOURCES OF ENERGY
Lesson 1: GETTING STARTED
A different type of footprint
Who are they?
What are they talking about?
You can guess.
Nam
Mai
Mai: Nam, I read yesterday that we all have a carbon footprint.
Nam: Well, we all have footprints–we make them with our feet!
Mai: Haha, I know that. But this kind of footprint is about the negative effect we have on the environment.
Nam: Right, it’s in the news a lot these days.
Mai: So our footprint is bigger when we use energy that produces carbon dioxide. That’s bad for the environment.
Nam: So it’s better to have a smaller footprint, right?
Mai: Right, Nam. Non-renewable energy sources like coal, natural gas, and oil produce a lot of carbon dioxide .Those sources are going to run out soon, too.

Nam: So, they’re different to wind, hydro, and solar?
Mai: Yes, they’re all sources of energy too, but they’re renewable. That means they can use them all up – They will last forever.
Nam: Do you have a big carbon footprint, Mai ?
Mai: Mine’s small. I recycle the products I use and I go everywhere by bike. We have solar panels on our roof at home to catch the sun’s energy, too.
Nam: Oh no! I think my footprint is big, and not just because of these big shoes!
II. Listen and read:
Dấu chân cacbon
ảnh hưởng tiêu cực
Cạn kiệt
Thải ra
Có thể phục hồi
Không thể phục hồi
Pin mặt trời
Dấu chân cacbon là lượng khí CO2 mà bạn đưa vào khí quyển. Nó được sinh ra bởi các hoạt động của con người

Có thể em chưa biết ?

Không phải là quốc gia xanh, xây nhiều nhà xanh, trồng nhiều cây xanh là có Dấu chân Carbon thấp.
Ví dụ như : quốc gia được gọi là "Quốc đảo Xanh" Singapore lại đứng trong hàng top các quốc gia có mức phát thải khí CO2 cao nhất thế giới.
Do đó, có thể thấy rằng, để có một quốc gia xanh bền vững đúng nghĩa, chúng ta cần phải làm nhiều thứ hơn.
Carbon footprint – Dấu chân cacbon

What is a carbon footprint?


2. What does `non-renewable energy` mean?


3. Why is sunlight a renewable source?

4. Why does Mai think she has a small carbon footprint?


5.What things do you think might create a big carbon footprint?

It’s about the negative effects we have on the
environment.
Non- renewable energy means that it will run out if we use it.
Sunlight is a renewable source because we can’t use it all up or it will last forever.
Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike.
The products that we use are bad for the environment or the energy that we use produces carbon dioxide might create a big carbon footprint .
1. a. Read the conversation again and answer the questions
Sources of energy
Renewable
sources
Non -renewable sources
b. Complete the network below using information from the conversation.
wind
hydro
solar
coal
natural gas
oil
2. Listen and repeat the words and phrases.
3. Put the words into the correct groups bellow

Wind
Hydro
Biogas
Nuclear
Solar
Natural gas
oil
coal
4. Practise asking and answering the questions about renewable and non-renewable sources.
Example:
A: What type of energy sources is wind?
B: It’s a renewable source of energy.
A: What type of energy source is coal?
B: It’s a non-renewable source.
Homework
1. Learn by heart vocabulary introduced in the lesson.
2. Re-read the dialog.
3. Write a paragraph: how to reduce carbon footprint.
4. Prepare new lesson : Unit 10. A closer look1.
Thanks for your attention!
