1. Low Carbon Council → Low Carbon Gwynedd By Marial Edwards SAVING ENERGY

2. Low Carbon Council → Low Carbon Gwynedd Learning Objectives You will understand: What is energy and the uses of energy The difference between renewable and non- renewable energy Why we need to save energy How we can save energy and be more energy efficient How to measure energy savings

3. Low Carbon Council → Low Carbon Gwynedd What is energy? What have you got at home or at school that uses energy?

4. Low Carbon Council → Low Carbon Gwynedd NON-RENEWABLE ENERGY Fossil fuels are sources of non-renewable energy. Most of the electricity in the UK is produced by burning fossil fuels in large power stations. They take millions of years to create and will soon run out. Can you name the fossil fuels? CoalGasOil

5. Low Carbon Council → Low Carbon Gwynedd RENEWABLE ENERGY Renewable energy are sources which can be reproduced over and over again. Renewable energy sources are greener and better for our planet than Non-renewable energy sources. Can you think of any? SOLAR ENERGY WIND POWER BIOMASS HYDRO ELECTRIC GEOTHERMAL

6. Low Carbon Council → Low Carbon Gwynedd NUCLEAR ENERGY Nuclear power stations creates about 18% of the UK’s electricity from a small amount of element called Uranium There are no CO 2 emissions from nuclear power stations Some of the waste created contains radiation which must be kept safe for thousands of years.

7. Low Carbon Council → Low Carbon Gwynedd Our planet needs YOU! Why is it important to save energy?

8. Low Carbon Council → Low Carbon Gwynedd The reasons to SAVE energy 1.To SAVE the environment 2.To Save our planet’s Non-renewable energy sources 3. To SAVE money

9. Low Carbon Council → Low Carbon Gwynedd 1. To SAVE the environment

10. Low Carbon Council → Low Carbon Gwynedd Did you know? Everyday, when we travel in cars and use electricity and heating in our homes, we release a gas called carbon dioxide (CO 2 ). When CO 2 is released, it pollutes the atmosphere. CO 2 is a major contributor of the green house effect and speeds up the changes in our climate.

11. Low Carbon Council → Low Carbon Gwynedd What is climate change? CO 2 traps heat in the atmosphere, similar to a warm blanket. We need this blanket to stop the Earth from freezing. However, too much CO 2 in the atmosphere makes the planet too hot and creates what is known as the Greenhouse Effect. The long term result is Climate Change (or Global Warming) – changes in world temperatures and weather patterns over a long period of time. Who would like to come to the front to demonstrate this?

12. Low Carbon Council → Low Carbon Gwynedd Negative Effects: Climate Change Ice melting and sea level rising.

13. Low Carbon Council → Low Carbon Gwynedd Negative Effects: Climate Change More floods due to heavy rainfall and strong winds in countries like Wales.

14. Low Carbon Council → Low Carbon Gwynedd Negative Effects: Climate Change More drought already seen in several countries on the Equator.

15. Low Carbon Council → Low Carbon Gwynedd Negative Effects: Climate Change Diseases, such as malaria, that appear in hot climates are spreading as mosquitoes move to colder climates.

16. Low Carbon Council → Low Carbon Gwynedd Negative Effects: Climate Change Plants and animals are becoming extinct (up to 1/3 could disappear by 2050) Oceans getting warmer and turning too acidic.

17. Low Carbon Council → Low Carbon Gwynedd 2. To SAVE non-renewable energy sources Fossil Fuels are running out –40 years of oil left –65 years of gas left –200 years of coal left

18. Low Carbon Council → Low Carbon Gwynedd 3. To SAVE money Save energy = Save money! Together we can save millions of £££ on our heating and electricity bills by not wasting energy.

19. Low Carbon Council → Low Carbon Gwynedd Is your school contributing to climate change? Ysgol Ein Harglwyddes produced 44 tonnes of CO 2 in 2009 This is enough CO 2 to fill 264 double-deckers OR 44 hot air balloons

20. Low Carbon Council → Low Carbon Gwynedd Switch them off!

21. Low Carbon Council → Low Carbon Gwynedd Hot and bothered! REMEMBER 18°C

22. Low Carbon Council → Low Carbon Gwynedd Close them! Close doors and windows to prevent the heat from escaping!

23. Low Carbon Council → Low Carbon Gwynedd Don’t waste it!

24. Low Carbon Council → Low Carbon Gwynedd Have you saved energy? Every month, note your school’s electricity and gas meter readings to find out if your school is using less energy. Send your readings to the suppliers (British Gas / Corona Energy)
