  1. What did you do this morning which used Electricity? 2

  2. Which uses more electricity? 3

  3. Which uses more electricity? 4

  4. Which uses more electricity? 5

  5. Which uses more energy in a year in an average household? 1 3 2 6

  6. How is electricity made? Sun Wind • Coal Water Nuclear 7

  7. How does electricity get from where it is made to us? This system is called the National Grid 8

  8. Let’s make our own National Grid 9

  9. Your task: Imagine each of you is an electricity pylon, and the string is the wires, connect as manypeopleas possible to the power source. 10

  10. Technology Justice 1.4 billion people don’t have any electricity that’s one third of the world 33% 1/3 Is this fair? We don’t think so. We believe everyone should be able to have electricity and other things that mean they will have a decent quality of life. We call that Technology Justice 11

  11. What else is being done to help people in places like Kenya? In year 2000 world leaders got together and said they wanted to help people in developing countries like Kenya get out of poverty and lead a decent life. They set themselves 8different goals to make this happen by 2015. They called these the Millennium Development Goals General Ban Ki Moon United Nation’s General Secretary 12

  12. Why is electricity so important for Technology justice? …let’s find out why one charity called Practical Action thinks electricity is important and what they are doing to help make technology justice a reality. http://www.youtube.com/watch?v=usISdE-WSWU 13

  13. Using the power of the wind is one way we can make electricity Wind turbines turn the wind into electricity • Wind turbines can provide energy for communities not connected to the national grid…reaching the very poor. • Wind is a renewable energy, it is sustainable… it doesn’t harm other people or the environment. 14

  14. How does a wind turbine work? • Wind turns the blades round. • They are connected to the generator, so bits inside the generator turn. • The generator makes electricity. • The electricity can then go through a wire to your house 15

  15. Different kinds of wind turbines There are many different kinds of turbines,each with different features 16

  16. Your task… A set of wind turbine blades has broken in your community, you need to design and build replacement blades 17

  17. Your materials… 18

  18. A wind turbine in rural Africa 19

  19. Enjoyed the workshop? What’s next? Find out more about renewable energy by going to Ewb-UK.org and Practicalaction.org Take part in one of Practical Action’s STEM challenges www.practicalaction/STEM See how you could become an engineer working renewable energy www.practicalaction.org/careers Spread the wordTell other people at school and at home what you have learnt 20
