Unit 10: SOURCES OF ENERGY

Lesson 1: GETTING STARTED
A different type of footprint

1. Listen and read.
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. Practice :
1. What is a carbon footprint?
2. What does “non renewable energy” mean?
3. Why is sunlight a renewable resource?
4. Why does Mai think she has a small carbon footprint?
5. What things do you think might create a big carbon footprint?
a. Answer the following questions.
It’s about the negative effect we have on the environment.
Non –renewable energy means that it will run out if we use it.
Sunlight is a renewable energy because we can’t use it all up, it will last forever.
Because she recycles the products she uses and she goes everywhere by bike.
The products we use that are bad for the environment or the energy we use that product carbon dioxide might create a big carbon footprint.

3. Put the words into the correct groups below.
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.
