2 Where does our electricity come from? This is how electricity gets into our homes

3 Where does our electricity come from? How many points can you score for giving the right answers to this energy quiz? Good ideas and suggestions can earn a point too, if your teacher decides you deserve it!

4 Where does our electricity come from? Now we know how electricity gets to our homes. But where is the electricity produced? Part A. One point for correctly filling in each word. 1. Electricity is conducted to the light along w_ _ _ _. 2. The electricity we use is measured by a m _ _ _ _. 3. Cables carrying electricity to the house can be supported by p _ _ _ _ or py_ _ _ _. 4. Sometimes the cables carrying electricity to the house are b _ _ _ _ _ beneath the ground. i r e s e t e r o l e s l o n s u r i e d

5 Where does our electricity come from? Here are some of the places where electricity is produced. A B C D Coal fired power station Wind Farm Gas fired power station Nuclear power station Part B. Do you know which picture is 1. The wind farm 2. The coal fired power station 3. The nuclear power station 4. The gas fired power station

6 Where does our electricity come from? Part C. Look at the diagram then fill in the missing words below. 1. In the coal and gas fired power stations, water is h _ _ _ _ _ 2. The water vaporises into s _ _ _ _ 3. The steam is used to t _ _ _ a turbine 4. The turbine generates e _ _ _ _ _ _ _ _ _ _ e a t e d t e a m u r n l e c t r i c i t y

7 Where does our electricity come from? Good news or bad news – Coal fired power stations Good newsBad news Part D. In which column would you put each of the following? 1.These power stations produce lots of electricity in the UK (37%). 2. They cause pollution that contributes to global warming. 3. The coal they burn is gradually running out. 4. Mining the coal provides jobs for people. 5. Coal has to be transported great distances from other countries.

8 Where does our electricity come from? Good news or bad news - Gas fired power stations Good newsBad news In which column would you put each of the following? 1.These power stations produce lots of electricity in the UK (30%). 2.The gas they burn is gradually running out. 3.Gas has to be transported great distances from other countries. 4.They cause pollution that contributes to global warming.

9 Where does our electricity come from? Good news or bad news - Nuclear power stations Good newsBad news In which column would you put each of the following? 1.These power stations produce lots of electricity in the UK (20%). 2.Nuclear power does not produce carbon dioxide. 3.The power stations use an expensive and quite rare fuel called uranium. 4.Nuclear power stations produce radioactive waste that will be dangerous for thousands of years and is difficult and expensive to store safely.

10 Where does our electricity come from? Good news or bad news - Wind Farms Good newsBad news In which column would you put each of the following? 1.There is a lot of wind in the UK. 2.Wind turbines don't produce carbon dioxide or other air pollution. 3.Wind power will not run out. 4.They dont work when it is not windy. 5.Some people think that they look ugly and spoil the view. 6.They produce only a small amount of our electricity (less than 5%). 7.It takes a large number of turbines to produce as much electricity as a coal, gas or nuclear power station. 7
