Watch the descriptions of renewable energy sources in your notebook. 00:00:03
Right. 00:00:09
A. Electricity is produced by kinetic energy from moving water. 00:00:11
What do you think? 00:00:16
A is? 00:00:18
Hydroelectric. 00:00:21
Good. Hydroelectric. 00:00:25
B. Solar panels drop energy from the sun and are transformed into electrical energy. 00:00:29
What do you think? 00:00:39
Solar. 00:00:40
C. The blades move turbines which transform kinetic energy into electrical energy. 00:00:41
What do you think? 00:00:52
What do you think? 00:00:54
Okay, we're going to leave it here. 00:00:57
Energy from the movement of waves is transformed... 00:01:02
Energy from the movement of waves is transformed into electrical energy. 00:01:06
Tidal. 00:01:23
Like tides, remember. 00:01:25
Chemical energy from plants and animals is transformed into electrical energy. 00:01:29
What do you think? 00:01:35
Thermal energy inside the earth is transformed into electrical energy, we think geothermal. 00:01:36
The blades, see, the blades move turbines which transform kinetic energy into electrical 00:01:58
energy. Alright? Perfect. Number five. Use chemical energy, electrical energy into thermal 00:02:06
energy. B is potential energy into energy, right? Okay. Six. Which is the best site? 00:02:21
What do you think is the best site to set or to build a wind farm near here? What do 00:02:50
What do you think? 00:02:57
In the country, right? 00:02:59
The country felt, right? 00:03:01
Not in the school. 00:03:03
Yes, in the mall. 00:03:05
Right? 00:03:07
B. Other sites that should definitely 00:03:09
not be used. 00:03:11
Buildings. 00:03:13
And C. 00:03:20
What can you tell nature lovers and bird lovers? 00:03:22
What do you think? 00:03:24
You can tell them 00:03:26
that these are renewable energy and it doesn't pollute okay it doesn't 00:03:30
pollute at all okay um number seven i think it would be correct because you haven't 00:03:42
walking there so the only thing that we had to add it was just your personal notes 00:03:53
that i'm gonna have later so now um please copy this and we're going to 00:04:00
oh no first first we're going to practice orally we're going to practice orally and later you copy 00:04:08
ready, steady, go 00:04:17
I have some questions 00:04:19
don't copy now 00:04:24
I have some questions for you now 00:04:25
right 00:04:27
ready 00:04:28
steady, go 00:04:33
well 00:04:36
there are two states 00:04:39
of energy 00:04:44
this area presents in an object 00:04:45
due to its position, what do you think it is? 00:04:50
potential, great, it is found in moving objects 00:04:53
it is also called energy of motion, is that? 00:04:57
kinetic, the energy 00:05:00
of an object due to its position of motion 00:05:03
so the sum of potential and kinetic is 00:05:07
mechanical, great guys 00:05:12
What are the four main properties of energy? 00:05:14
Energy can be stored, can be transferred, can be transported, and can be transformed. 00:05:20
Energy can be transferred, there are the four main properties of energy. 00:05:36
It can be transferred from one place to another, it can be stored, it can be used in another way, and energy can be transported from one place to another as well. 00:05:39
So it can be transferred, it can be changed, transported, it can be from one place to another, and transformed, it can be changed, okay? 00:05:53
Okay, so, sorry because I say transfer change, no, transfer is moving, you can move it, and transported is just like, it's in a place, and it can be used in another, okay? 00:06:05
The difference between transferred and transported is like transferred, you can move something from one place to another, and it's the same thing, right? 00:06:18
But in transporting, if you transport it through the electricity facilities or through the energy, right? 00:06:27
The energy can be transported by change, okay? 00:06:37
Like in the poetry. 00:06:41
Okay. 00:06:46
Tell me, the main advantages and disadvantages of non-renewable energy sources. 00:06:47
So, advantages. 00:06:53
Of renewables. 00:06:55
Renewable, non-renewable energy sources, like fossil fuels, fossil fuels, I am thinking. 00:06:56
Only to... 00:07:03
To store, right? 00:07:12
Yes. 00:07:13
It's easy to store. Great. Three more. 00:07:14
It's easy to transport. 00:07:22
It's easy to transport. More. 00:07:25
More. 00:07:27
Another difference? 00:07:29
Remember, it's available when we need it, and it can be used in many different ways, okay? 00:07:30
Four disadvantages. 00:07:41
Smoke. 00:07:44
Smoke, yes. They produce smoke with the water. 00:07:52
It's a no. 00:07:57
The nuclear plants are very expensive. 00:08:00
They can cause oil leaks. 00:08:04
They can cause air pollution. 00:08:10
And they will run out one day. 00:08:13
Yes, they will run out one day as well. 00:08:19
Nuclear energy, advantages and disadvantages. 00:08:21
Advantages of nuclear energy. 00:08:28
The production of nuclear energy doesn't pollute. 00:08:33
The nuclear energy is cheap to produce. 00:08:39
The very small amount of uranium produces large amounts of energy. 00:08:43
That means that we have this. 00:08:47
Disadvantages. Nuclear power plants are very expensive, right? 00:08:49
Nuclear waste is highly contaminating, and nuclear waste needs hundreds of years to stop being radioactive. 00:09:02
Okay, tell me the negative consequences of burning fossil fuels. 00:09:10
the advantages 00:09:16
no, the negative consequences 00:09:22
of burning 00:09:24
fossil fuels 00:09:25
I told you 00:09:27
thermal warming 00:09:29
yes 00:09:32
the thermal energy 00:09:33
from the sun is absorbed 00:09:35
by the surface of the earth 00:09:37
some sunlight 00:09:40
returns to the space 00:09:42
some heat is naturally retained 00:09:44
when it houses 00:09:46
and all the rates of the temperatures. 00:09:47
The burning of fossil fuels releases high levels of carbon dioxide, 00:09:52
so it means that we need oxygen and a large amount of carbon dioxide 00:09:56
that can be really useful for our animals and any other ecosystem. 00:10:04
So, carbon dioxide and other gases are in the layer on the planet, that's not good, and what we said about global warming. 00:10:13
Four consequences of global warming. 00:10:30
The consequences of global warming. 00:10:35
It can damage animal habitats, which means that it can disappear and stink. 00:10:40
It can damage the, how do you say, the other crops and the folks. 00:10:45
Also, the weather conditions can damage it as well. 00:10:53
It can lead to some animals, some plants to die. 00:10:58
The plants of the sea? 00:11:03
Yes, the sea plants. 00:11:06
And we have the warmer oceans that we were talking about. 00:11:08
And rising sea levels become... 00:11:12
Rising sea levels become... 00:11:14
Okay, this is the... 00:11:16
This is the exam. 00:11:18
Please try to pass. 00:11:20
Is there any doubt? 00:11:22
No. 00:11:24
No? Well, it's not enough. 00:11:25
