- 1. Generating electricity and Energy transfers Research file 2 <Type your name here>
- 2. You need to be able to: Move parts of a slide around Enter answers into boxes Switch between here (PowerPoint) and the internet Save your work regularly Follow the instructions (they are in this colour), then delete the instructions including this slide. Avoid printing until you are told to.
- 3. Advantages and Disadvantages Use the internet and any other material to find the advantages and disadvantages of various ways to make electricity. As you read, look for information such as the following: Is the resource renewable? Can you count on it always working? Does it cause pollution and what kind of pollution? Does it take up lots of land? Is it expensive to set up? Is it expensive to run? Can it be built anywhere or does it need to be built in a specific place?
- 4. Natural Gas Advantages Unlike burning coal, burning natural gas does not release sulfur dioxide. Disadvantages Burning natural gas releases a large amount of carbon dioxide into the atmosphere. Use the internet sites provided to find the advantages and disadvantages of using natural gas to generate electricity. Two have been done for you. Think about pollution and efficiency
- 5. Solar Cells Advantages Disadvantages Use the internet sites provided to find the advantages and disadvantages of using solar cells to generate electricity. Are solar cells efficient? How much do they cost?
- 6. Wind Turbines Advantages Disadvantages visit some of the internet pages to find out about wind turbines. Think about the ways that the turbines affect the environment
- 7. Hydroelectricity Advantages Disadvantages Think about what happens to land Think about pollution and efficiency
- 8. More Advanced In the next slides you need to think about Wasted energy Extra energy transfers
- 9. Tidal Barrage Advantages Disadvantages Think about how the barrage effects the environment Think about how much electricity we can produce and pollution
- 10. Wave Power Advantages Disadvantages Think about the reliability and pollution Think about the costs
- 11. Wood Burning Advantages Disadvantages Is wood a renewable resource? Is there any pollution?
- 12. Geothermal Energy Advantages Disadvantages Is geothermal energy reliable? Where do the plants need to be built?
- 13. Extra Tasks There are other types of energy resources that you might find out about. Look up and add slides about nuclear power, alcohol fuel or hydrogen fuel cell or even solar heating and add these to your show.
