How is electricity made?

Wind Sun

WaterNuclear

Coal

How does electricity get from where it is made to us?

This system is called the National Grid

8

Let’s make our own National Grid

Your task:

Imagine each of you is an electricity pylon, and the string is the wires, connect as many

people as possible to the power source.

Technology Justice

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

1.4 billion people don’t have any electricity that’s one third of the world

33%

1/3

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 8 different goals to make this happen by 2015. They called these the

Millennium Development Goals

General Ban Ki MoonUnited Nation’s General Secretary

Using the power of the wind is one way we can make 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.

Wind turbines turn the wind into electricity

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

Different kinds of wind turbines

There are many different kinds of turbines, each with different features

16

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

17

Your materials…
