12. Unit 10: Sources of energy Lesson 1: Getting Started
13. Who are they? What are they talking about? What is a different type of footprint? Sneak Peek
14. a. Read and underline keywords. 1. 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?
15. Ex 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 we can’t 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!

Mai thinks she has a small carbon footprint because she recycles the products she uses and she goes everywhere by bike. 5. What things do you think might create a big carbon footprint? The products we use that are bad for the environment or the energy we use that produces carbon dioxide might create a big carbon footprint.
