Unit 10: SOURCES OF ENERGY
Lesson 1: GETTING STARTED

I. Vocabulary
Solar panel (n):
Renewable (adj):
Có thể phục hồi, tái tạo
Environment (n):
Môi trường
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
Who are they?
What are they talking about?
You can guess.

1. Listen
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: Ha ha, 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:

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
enviroment.
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 enviroment or the energy that we use produces carbon dioxide might create a big carbon footprint .
