1. Where Does our Power Come From? L.O: Evaluate the advantages and disadvantages of energy sources, and determine how energy should be generated in the future Starter: –Make a list of things that you use electricity for each day (at least 8) EXT: Rank them from most to least important and write down why your #1 choice is most important

2. Sustainability Use the following words to create a definition of sustainability: futureneedstoday meetinggeneration "Meeting the needs of people today without preventing future generations from meeting their needs."

3. The energy that powers our daily lives comes from two source types: –Renewable Resources –Non-Renewable Resources Where does our energy come from?

4. Renewable energy comes from natural resources that can replace themselves over time. –These include the sun, water and wind which won’t run out. What are renewable resources?

5. Advantages: –No CO 2 emissions which causes global warming –Cheap to generate from existing power plants Disadvantages: –Expensive to build new power stations –Impacts on the environment (fish barrier) Renewable Energy: Hydro-Electric Power

6. Renewable Energy: Wind Power Advantages: –No CO 2 emissions –No long term harm to animals habitats Disadvantages: –Unpredictable power –Hard to store –Visual & noise pollution

7. Advantages: –Each household can produce some of their power –You don’t have to pay a power company –No CO 2 emissions Disadvantages: –Unpredictable sunshine hours –Expensive to set up Renewable Energy: Solar Power

8. Advantages: –Ocean currents are constant –Unaffected by weather –No CO 2 emissions Disadvantages: –Destroys fish habitat –High cost Renewable Energy: Tidal Energy

9. A non-renewable resource is something that is in limited supply, and once used cannot be replaced. –Coal, oil and gas are called fossil fuels as they were once living things (plants and animals), now fossilised over thousands of years. What are non-renewable resources?

10. Advantages: –World set up for oil –Relatively Cheap Disadvantages: –Only 40 years supply readily available –CO 2 causes global warming –Smog –Oil ownership has started wars Non-Renewable Energy: Oil

11. Advantages: –Cheap –Plentiful - at least 1000 years supply Disadvantages: –Smog –CO 2 causing global warming –Releases radio active waste when burnt for electricity Non-Renewable Energy: Coal

12. Advantages: –Cheap –Natural –Popular Disadvantages: –Existing gas fields running out –Highly flammable –When gas is removed from the ground it can cause the ground slump Non-Renewable Energy: Gas

13. Advantages: –High energy production –No greenhouse gases –Cheapest energy source in Europe Disadvantages: –Uranium will last only 70 years with current consumption –Disposing of radioactive waste is dangerous –Meltdown – Chernobyl (Ukraine) Non-Renewable Energy: Nuclear Power

14. What are key energy sources? Place the following labels in the correct column then shade the label to indicate whether it is renewable or non- renewable. Put a circle around the fossil fuels. NuclearSolarTideHydroOil Coal Natural Gas Wind

15. Electricity Use

16. Electricity in the UK Task –Glue in your Electricity Generation pie graph ALL: What percentage of UK’s electricity generation comes from non- renewable sources? MOST: Write a paragraph explaining whether you think this has changed since 2004 and why/why not. SOME: What type of renewable energy source should the UK use more of?

17. Complete the electricity generation worksheet. EXT: Write down some advantages and disadvantages of your electricity generation Electricity Generation

18. So why reduce the amount of electricity we use? –Save the environment from fossil fuels –Save the environment by reducing need for more wind farms and hydro-dams –SAVE MONEY!! Electricity Reduction

19. Earth Hour Sydney 2007 Went global 2008 http://www.youtube.com/watch?v=1CRs- 7lRlPo&safe=active In 2013 approximately 1 billion people participated in Earth Hour Electricity Reduction: Global Phenomenon Think back to the list you made at the start of the lesson:  Could you go one day without electricity?  Why/why not?

20. L/O: Evaluate the advantages and disadvantages of energy sources, and determine how energy should be generated in the future. Where are we on our progress line? What questions do we have? I fully understand the LO I’m not really sure what the LO is about

21. Complete a 3, 2, 1: –3 things you learnt –2 things you found interesting –1 question you still have Homework
