Your Planet Something to think about... How many different ways of using electricity can you think of?

Lesson outcomes By the end of this lesson I will be able to: explain why demand for electricity is increasing describe how future demand for electricity could be met.

Demand graphs Think about how electricity is used around your home. Sketch a graph to show how the demand for electricity varies in a 24 hour period. Hint: Is the demand for electricity likely to be high during the day when most of your family are out?

Demand What has happened to the demand for electricity over the last 30 years? Why do you think this is?

Worksheet Complete the worksheet - you have 15 minutes

Do the following statements describe reasons why the demand for electricity in the world is increasing? Increased development of more countries Increase in the cost in electricity Development of a nuclear fusion reactor Increase in population New government More electrical gadgets YesNo

How can the demand for electricity be met in the future? Use pages Choose one of these methods and write a short paragraph about it. Include: a brief description one advantage one disadvantage a conclusion.

This lesson I have learnt: global demand for electricity is increasing electricity generation at present heavily relies on fossil fuels and nuclear fission to meet future demand we need to consider renewable resources, for example, wind, waves, geothermal, and solar research is also being carried out into the feasibility of nuclear fusion.
