Mr Lam: As you know we use energy for cooking, heating and lighting. But it’s not cheap. So how can we save energy at home? Linh, what do you do to save electricity?
Linh: Well, I always turn off the lights before going to bed. I have some electrical appliances, such as a TV, a CD player,… I turn them off when I don’t use them. I think it helps us save electricity.
Mr Lam: You’re right. What about you, Minh?
Minh: Well, we use low energy light bulbs at my house. We always turn them off when leaving the room. We use solar panels to warm water too. It’s cheap and clean.
Mr Lam: Sounds interesting. And how about you, …?
