1. Expected Learning
To be able to define and identify renewable and non renewable resources
By the end of this lesson, you need to
1. Complete the renewable energy worksheet.
2. Create a poster “Top 10 reasons why renewable energy is cool!” in pairs or 5 reasons individually.
These tasks are assessment tasks!

2. Renewables Part 1
This has been written in 2 parts. Lesson could be run over one or two lessons depending on how you decide to run it. There are laminated printouts to go with each part.

3. Are we running out of fuel?
PART 1
Are we running out of fuel?
Yes
Start this lesson by asking students if they think we are running out of fuel. They can line up along an opinion line in the classroom or have one side of room for yes, one side for no and another area of the room for those who are undecided, somewhere in the middle etc.
Take the opportunity to probe their opinions and tell them that you will do this at the end also.
Get students to collect an A4 copy of slide 4.(Case Study Slide…..Are we running out of fuel). YOU NEED TO PRINT THESE
The question has been specifically worded the way it is to make students aware that most current fuel sources will run out however energy resources like wind and solar will not. No

4. Coal
Coal is as a solid fuel used to produce electricity and heat through burning, some power stations use coal. World coal consumption was about 6.75 billion tons in 2006 and is expected to increase 48% to 9.98 billion tons by 2030. 
Coal is sometimes used in the home for heating but produces lots of soot. Coal is a non-renewable fuel.
No one knows for sure how much coal is left for sure but we do know there are at least 147 years worth of coal left.
Differentiated for lower ability but is ideal for identifying the PEE paragraph
P Coal will run out
E There is only 147 years of coal left
E This means that we will run out of fuel soon.

5. Renewables Part 2

6. Part 2
Energy
Energy comes from many sources, and to describe these sources we use two terms:
Renewable and Non-renewable
Can you describe what each of these terms mean?
After completing “Are we running out of Fuel” activity go through definitions with them of Non-Renewable and Renewable to get them thinking about the different sources of energy available to us.
Prompt students to come up with definition for both terms before revealing definitions on next slides.

7. Non-Renewable Energy Non-renewable energy resources cannot be replaced
– once they are used up, they will not be restored (or not for millions of years).
Can you think of any Non-Renewable Energy Resources?
Students are to write definition of Non-Renewable Energy into their workbooks.
Prompt students to come up with list of Non-Renewable Energy Resources.
This can prompt a discussion on fossil fuels and how they were formed etc before moving onto Renewable Resources

8. Renewable Energy
Renewable energy is fuel that comes from a source that can be replenished in a short amount of time.
Can you think of any Renewable Energy Resources?
Students are to write definition of Renewable Energy into their workbooks.
Prompt students to come up with list of Renewable Energy Resources.
Use next slide for a quick check on whether they can identify Renewable V Non-Renewable resources

Ask students to suggest which resources are Renewable V Non-Renewable. Click on boxes to reveal correct answer. Students should make note in their workbooks of each energy source and whether it is renewable or non-renewable

10. Geothermal Energy – energy from the Earth
Deep underground, the Earth’s rocks are naturally very hot. We can turn their heat energy into electrical energy to use in our homes – we call this ‘geothermal energy’.
Cold water is pumped below the ground.
Hot rocks heat the water, turning it into steam.
The steam is used to generate electricity.
Renewable
No pollution, because nothing gets burned
Doesn’t damage the environment
Very few places in the world where you can do this
Costs a lot of money to drill deep into the ground
The following slides contain information on Renewable sources of energy. They can be placed around the class for students to review and fill in worksheet “Renewable Energy Worksheet” or each table group can be given a handout of one of the renewable energy sources and they use this as a basis to prepare a short presentation to the class on this renewable source of energy.
Presentation should include:
Where the energy comes from, How it works, Advantages/Disadvantages and any other relevant information they can find. They must do further research, not just use the info on the handout. As each group presents, the other groups complete the worksheet with info they get from other groups presentations.
Don’t necessarily need to print this worksheet, just get students to complete a table in their workbooks

11. Wave Energy – energy from sea waves
The sea’s waves have kinetic energy. Using machines that bob up and down in the waves, this energy can be turned into electrical energy which we can use in our homes.
wave energy machines bobbing up and down in the waves
Need lots of machines to get a reasonable amount of energy
The machines costs a lot of money
The machines can look ugly
The machines can be damaged by storms
Renewable
No pollution, because nothing gets burned

12. Hydroelectric Energy – energy from rivers
The water flowing in a river has kinetic energy. We can turn this into electrical energy to use in our homes. We usually need to build a dam, and let the water flow through it gradually.
Renewable
No pollution, because nothing gets burned
We can store the water up high, and then whenever we need the energy we can let the water out
Costs a lot of money to build a dam
The dam can ruin the local environment, because it changes where the water naturally flows. Some animals and plants may die.

13. Tidal Energy – energy from sea tides
If you’ve ever been to the coast, you may have noticed that the sea level goes up and down, because of tides. When the tide is high, the water has lots of gravitational potential energy, which we can turn into electrical energy to use in our homes.
At high tide, we trap the water behind a dam.
At low tide, the water is released, and its energy is used to generate electricity.
Renewable
No pollution, because nothing gets burned
Reliable, because there are always two tides every day
Cheap to run, once it’s built
Costs a lot to build the dam
The dam may cause local flooding

14. Solar Energy – energy from the Sun
The Earth gets heat and light energy from the sun all the time. Can we use it – yes we can! The Sun’s energy can either be:
changed into electrical energy to use in homes, using solar cells;
or used to heat water for homes, using solar panels.
Renewable
No pollution, because nothing gets burned
Solar cells and solar panels are expensive
Only works if it’s sunny!

15. Wind Energy – energy from the wind
Using wind turbines, we can turn the kinetic energy of the wind into electrical energy which we can use in our homes. This is ‘wind energy’.
Renewable
No pollution, because nothing gets burned
Turbines are quite cheap and easy to build, so they can be used even in poor countries
Turbines can be ugly and noisy
Only works if it’s quite windy! If the wind stops, you get no energy.

16. Biomass Energy – energy from plants and animals
Biomass is plant and animal matter, such as wood, straw, sewage and waste food. We can burn these natural materials to produce heat and electricity. The Earth’s biomass is a huge store of energy, which is continually renewed by the sun through photosynthesis.
Energy crops such as wood, oilseed rape and sugar beet are specially grown for fuel. A form of bio-diesel can be produced from vegetable oils. Other crops can be fermented to produce ethanol, a high-energy substance similar to petrol.
Waste is an important source of bio-energy. Landfill sites, animal droppings and sewage all give off methane gas as they rot. Methane can be burnt to produce electricity and heat.
+ It is not using up limited resources like coal: biomass cannot run out.
+ It helps get rid of waste, which can cause smells and
+ The fuel is cheap.
- Collecting waste in big enough amounts to generate energy can be difficult.
- Burning the fuel creates carbon dioxide, a greenhouse gas. However, if you grow crops that absorb the same amount of carbon dioxide from the air that is created by burning them, the effect on the environment is less harmful.
