0:07 In this lesson you will learn how to talk about alternative and clean energy.
0:18 Sometimes I’m afraid of these wind farms. Don’t you think those large fans will break if a hurricane comes?
0:24 Don’t think of crazy things like that! They’re way too heavy and strong to be blown over by a hurricane
0:32 I was just wondering. It seems we have no electricity problems now, though.
0:36 Thanks to renewable energy!
0:39 By the way, why is it called renewable energy?
0:42 Because this energy is created by natural sources, like the sun and the wind, which are not exhausted when they’re used.
0:51 They don’t produce any pollution either, right?
0:51 They don’t produce any pollution either, right?
0:54 Correct! That’s why they are also called “clean” energy.
1:04 Hans, what are you're doing on the roof?
1:06 I’m installing a solar-panel roof! Goodbye, power bills!
1:10 You mean you’ll put solar panels on your roof?
1:13 Yup! My roof tiles were old, anyway.
1:16 Great idea, but what about the rainy season?
1:19 That’ll be fine, I didn’t disconnect the power cables.
1:23 So, you’ll use both. Man, I should get a solar roof, too!
1:27 Of course you should, you’ll save money and help the environment!
1:36 Billy, have you noticed there’s something different about the city?
1:40 You're right! It feels a bit livelier than before.
1:44 What’s different?
1:45 I think it has something to do with the taxis!
1:48 Taxis?
1:50 The new Mayor ordered all the taxis and public transport to use clean fuels that do not produce much pollution.
1:57 Thanks to the Mayor, this city doesn’t stink of oil or smoke anymore!
2:07 The electricity bill is killing me! They’re going to raise the rates again!
2:13 I think it’s better to switch to alternative energies.
2:17 You mean solar energy?
2:19 For us, yes! But there are other types too, like nuclear power and wind power.
2:25 Yeah! I heard they are also extracting energy from the ocean and seas.
2:31 That’s right. They can even make energy from garbage!
2:35 Hmmm...That’ll really help us control pollution.
2:41 Sometimes I’m afraid of these wind farms.
2:47 It seems we have no electricity problems now, though.
2:54 They don’t produce any pollution either, right?
3:01 I’m installing a solar-panel roof!

3:22 I think it’s better to switch to alternative energies.
3:22 I think it’s better to switch to alternative energies.
