Lesson video

Hi everyone, I'm Miss Reid and welcome to our last lesson on energy and sustainability.

Let's have a look at our key question for today's lesson.

So our key question is, what does the future hold? a fitting question for our last lesson, thinking about what can we do in the future? Well, in this lesson, we'll be learning about energy security, and the need to shift to renewable, sustainable forms of energy.

We'll learn about energy security strategies, and innovative approaches to energy production.

So we'll be looking at Star Words, and then we'll be learning about Energy Security before Analysing Data by looking at a Pie Chart.

Then we'll think about Energy Security Strategies before thinking about Waste to Energy.

So in this lesson, you'll need an exercise book or a piece of paper, you'll need a pencil and you'll need your brain.

Pause the video now.

If you to go and get those things.

So let's have a look at our star words.

I'm going to say the star word and I want you to repeat it after me.

Energy Security, sustainable, renewable energy, non renewable energy, environment, economy, great.

So, we're going to read some information about energy security.

I'm going to read along and I want you to read along with me at home.

Energy Security is when a country is able to provide enough reliable and affordable energy to all its citizens throughout the year.

A lack of energy security can cause many economic and social problems, such as high prices or ill health now, high prices are often caused because a small number of countries are able to extract energy sources, predominantly fossil fuels, meaning that they can raise the price of products.

For example, the United States, Saudi Arabia and Russia are able to extract oil, which means that they can control the price of the oil as they sell it to other countries.

When we think about ill health, well, ill health can be caused by lots of pollution being released into the air when burning fossil fuels, so toxic fumes being released from those factories.

Let's keep reading.

Energy Security is usually established by using different types of energy.

However, that is concerned of the future of energy security for many countries due to the reliance on fossil fuels.

Countries must keep transitioning to renewable energy sources to ensure that they have energy security.

Now, there was some key words in that, or in those paragraphs, thinking about reliable if something is reliable, so reliable energy, it means that you can always rely on it.

Now, non renewable energy sources are not reliable because they won't last forever, whereas renewable energy sources are reliable because they will last forever.

If something's affordable.

That means that people can afford to buy the energy or electricity and citizens that will those people.

And when we think about economic, well, that's about the economy, the money that is made in the country, and thinking about social or social problems. Well, this is about the people.

So those are those key words explained here I've got some true or false questions for you that are based on the text.

One, energy security is when a country provides affordable energy to its poorest citizens.

True or false.

Two, energy security is usually established by using one type of reliable energy.

True or false.

Three, countries need to keep transitioning to renewable energy sources.

True or false? Now you need to use the information in the paragraphs in order to answer these true or false questions.

You can write true or false next to one, two and three.

Pause the video now so you can complete that task.

Let's have a look at the answers.

So number one, energy security is when a country provides affordable energy to its poorest citizens.

Well, that was false, because energy security is about providing reliable and affordable energy to all of the citizens, all of the people in the country.

Number two, energy security is usually established by using one type of reliable energy.

Well, that's false as well, because energy security is about using lots of different types of reliable energy sources.

And three, countries need to keep transitioning to renewable energy sources.

That is, of course true.

Let's move on.

Before we move on, I'll give you a chance to tick or fix your answers.

Pause the video now so you can do that.

Great work.

So, this is the UK you can see the Union Jack on that image of the country.

Now, the UK produces a lot of its own electricity, but it also imports electricity from other countries.

So imports means that it buys energy from other countries, it's bringing a product into the country from another place.

Now these countries that provide the UK with extra energy or electricity are called interconnectors.

I'm going to say that word and I want you to repeat after me, interconnectors.

Now, some examples of these interconnectors that provide electricity to the UK are France, Norway, and the Netherlands.

Now, when these countries have an excess of electricity produced in those countries, they can sell it to the UK which can help save people money in the UK when they're buying their electricity.

Here's a task for you, you need to answer the question below.

It says name three countries that are interconnectors to the UK.

Pause the video now and complete that task.

Did you remember let's have a look at the answers.

Those interconnectors were France, Norway and the Netherlands.

Pause the video now so you can take or fix your answers.

Well done everyone.

Let's move on.

So here is a pie chart to show the percentages of the UK total energy consumption in 2019.

Now this information comes from smarter business.

And you can see that the pie chart has split up those percentages to show what amount of energy was consumed by coal, gas, renewable energy.

Let's have a closer look at all of those.

So, you can see that 40.

7% of the country's energy was generated by natural gas or gas.

And that's the large green section.

Can you point at the at the large green section that shows 40.

7%? We pointing here.

Excellent work.

28.

1% of the country's energy was generated by renewables such as wind, solar, Hydro and bio energy.

Can you point at the section of the pie chart that shows The renewable energy that was consumed.

Were you pointing here? Excellent work 22.

5% of the country's energy was generated by nuclear power.

Can you point at the section of the pie chart that shows the nuclear power? Are you pointing here? Great work.

1.

3% of the country's energy was generated by coal.

Can you point at the section of the pie chart that shows the energy generated by coal? This little section here in light blue should be where you're pointing at.

And finally, 7.

4% of the country's electricity was imported from other countries such as France, Norway and the Netherlands those interconnectors.

Can you point at the section of the pie chart that shows the energy or electricity that was imported? This is where you should have been pointing.

Great work, everyone.

So now you've had a chance to have a look at that pie chart and you've seen all the data, we're going to answer some questions based on the data you've looked at.

Number one, in 2019, what percentage of the UK electricity was generated from coal and gas? Now to answer this question, you're going to need to add the two values together and write your answer as a percentage.

Number two, in 2019, how is the majority of the UK energy generated? You can pause the video now.

So you can complete those two questions.

Let's have a look at the answers.

So number one in 2019, what percentage of the UK electricity was generated from coal and gas? Well, you have to put your mathematicians brain on here.

So well done the switching between those two interconnected skills.

So 40.

7 add 1.

3 because 40.

7% of the country's elec-energy was generated from coal at 1.

3%, which was the amount generated by gas and the answer is of course 42%.

You can pause the video now.

So you can tick or fix your answer, make sure if you got it wrong, that you're writing out the full equation.

And question two, in 2019, how was the majority of the UK energy generated? So this is the, we need to look at the largest section of the pie chart.

And if we go back, you can see that the largest section is that section in green.

And that relates to the gas section.

And that's the amount of energy that was produced by gas.

And that was, of course 40.

7%.

So back to our answer.

I've written it as a full sentence.

So in 2019, the majority of the UK energy was generated by gas.

Pause the video now so you can tick or fix your answer.

Let's move on.

So Energy Security Strategies.

Well, there are different ways in which countries can try to achieve energy security.

Some of the strategies include, we're going to look at five key strategies.

I'm going to read them out as they appear on the screen.

And I want you to read along with me.

One, Self sufficiency.

Can you repeat that after me, self sufficiency.

Let's keep reading.

Use your own natural resources to generate all your own energy, for example, Norway.

So Norway is an example of a country that uses all its own natural resources to generate all of its own energy.

Number two, Teamwork.

Repeat after me.

Great, let's read about teamwork.

Work with another country or countries to share resources.

For example, Canada exports gas and oil to the USA and the USA exports coal to Canada.

So that's an example of a partnership teamwork the US and Canada work together to share energy resources.

Number three, Diversify, your turn.

So diversify means import your energy from many different sources in case one fails, for example, Japan.

So Japan is an example of a country that imports its energy from different sources just in case one of their own, or one of the energy sources in another country fails Four, Use less.

So using less energy means you have to generate less of it, for example, Sweden.

So Sweden is a country that uses less energy, meaning that it has to generate less energy every year.

And five, Technology.

Technology is about developing new technologies so that you establish energy security, in your country.

So, constantly developing new technology, for example, bioenergy or hydro power, or using wind farms or solar, or solar farms means that you use new technology to generate new types of energy as those non renewable resources run out.

Let's go through those five again.

self sufficiency, teamwork, diversify, use less, technology.

Here you've got a task.

There are those five energy security strategies.

On the left hand side, self sufficiency, teamwork, diversify, use less and technology.

However, the definitions on the right hand side have been mixed up.

It's your job to match the strategy to the definition.

Now you don't need to write out the full words of the strategies, nor the full definitions, you can match the number to the letter.

Have a read through those on your own.

And pause the video so you can match the strategy to the definition.

Pause the video now to complete that task.

Let's check the answer.

So number one is march to C, let's have a closer look.

So self sufficiency one, C, use your own natural resources to generate all your own energy.

Number two, is march to, A, work with another country or countries to share your resources.

Number three, is march to, E, important imports your energy from many different sources in case one fails.

Number four, is march to B, using less energy means you have to generate less of it.

And number five is march to D, develop new technologies so that you establish energy security in your country.

Pause the video now so that you can tick or fix your answers.

Great work everyone.

Let's move to our last part of the lesson.

So Waste to Energy.

Well waste to energy is a way of transforming our waste into electricity or energy.

Let's have a look at the process.

So we create waste.

The waste is then transported in waste trucks, and it's taken to a waste power plant.

You can see an example there.

At the waste power plant, the waste is burnt to convert the energy into other forms of energy.

For example, energy for fuel, energy for gas or energy for electricity.

Now, this process is good for three reasons.

Firstly, the power plant burns waste in a way that does not harm the environment.

Secondly, thousands of homes are able to use the electricity generated and the wasteland even uses the energy it's created to power itself.

Thirdly, this is a revolutionary way to start repurposing the waste that we create as it means less waste is going to landfill sites which is harmful to the environment.

So those three reasons again, burning the waste doesn't harm the environment Two, power is generated thousands of homes and three, less waste is going to landfill sites which is harmful to the environment.

So here's the task.

You need to complete the sentences below using the keywords to help you.

Waste to Energy technology, is helping improve sustainability in three ways.

Firstly, secondly, thirdly, you can use the keywords to help you.

So, burns, not harmful, environment, power, thousands of homes, Repurposing, landfill sites, harmful, environment.

You can see that there's a slash in between those keywords.

And that should help you to use the key words for each sentence starter.

So burns, not harmful, environment can be used for Firstly, power, thousands of homes can be used for secondly, and repurposing, landfill sites, harmful environment can be used with a third sentence starter Thirdly, I want you to use the sentence starters and the key words to write the ways that Waste to Energy technology is helping improve sustainability.

Pause the video now so you can complete that task.

Great work everyone.

Let's have a look at the answers that I wrote and you can compare yours.

Waste to Energy technology is helping improve sustainability in two ways.

Firstly, it burns waste in a way that is not harmful to the environment.

Secondly, it provides power to thousands of homes.

Thirdly, repurposing the waste means that less waste means that less waste is going to landfill sites which is harmful to the natural environment.

Pause the video now so that you can tick or fix your answers.

Well done everyone.

That's the end of our lesson.

Well done in completing all of these lessons, everyone.

It's been fantastic to learn about energy and sustainability with you and I hope you've learned a lot about the world that you live in.

I certainly have.

I'm really really looking forward to seeing you in our next series of lessons.
