  1. SAVING ENERGY By Marial Edwards

  2. 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 Learning Objectives

  3. What is energy? What have you got at home or at school that uses energy?

  4. 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? NON-RENEWABLE ENERGY Coal Gas Oil

  5. 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? RENEWABLE ENERGY SOLAR ENERGY BIOMASS GEOTHERMAL WIND POWER HYDRO ELECTRIC

  6. Nuclear power stations creates about 18% of the UK’s electricity from a small amount of element called Uranium There are no CO2 emissions from nuclear power stations Some of the waste created contains radiation which must be kept safe for thousands of years. NUCLEAR ENERGY

  7. Why is it important to save energy? Our planet needs YOU!

  8. To SAVE the environment To Save our planet’s Non-renewable energy sources 3. To SAVE money The reasons to SAVE energy

  9. 1. To SAVE the environment

  10. Everyday, when we travel in cars and use electricity and heating in our homes, we release a gas called carbon dioxide (CO2). When CO2 is released, it pollutes the atmosphere. CO2 is a major contributor of the green house effect and speeds up the changes in our climate . Did you know?

  11. CO2 traps heat in the atmosphere, similar to a warm blanket. We need this blanket to stop the Earth from freezing. However, too much CO2 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. What is climate change? Who would like to come to the front to demonstrate this?

  12. Ice melting and sea level rising. Negative Effects: Climate Change

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

  14. More drought already seen in several countries on the Equator. Negative Effects: Climate Change

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

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

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

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

  19. Ysgol Ein Harglwyddes produced 44 tonnes of CO2 in 2009 This is enough CO2 to fill 264 double-deckers OR 44 hot air balloons Is your school contributing to climate change?

  20. Switch them off!

  21. Hot and bothered! REMEMBER 18°C

  22. Close doors and windows to prevent the heat from escaping! Close them!

  23. Don’t waste it!

  24. 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) Have you saved energy?
