5. Photo: Graham Turner Our energy is made in Power stations which burn fossil fuels to make energy Once electricity has been made it is moved over the country using pylons and enters our homes through wires. We plug appliances in to use the electricity. Cars also burn fossil fuels in the form of petrol and diesel to make them move.
12. Last year we made great progress in reducing energy consumption in school But there is still room for improvement. Eg. Last week over 40 lights were left on in classrooms at lunch when they didn’t need to be on There were over 60 appliances on or on standby over the lunch period when they didn’t need to be. On the first Power Ranger visit in October Over 60 appliances were left on or on standby over night.
13. We need everyone but especially the staff to Switch off lights when you leave a room Switch off anything on standby Switch off any electrical appliances completely (and appropriately) Close doors - reduces heat loss and saves energy.

16. At the end of the first week, we will carry out another audit of the school. We will be looking for the most improved classes in school . Another audit will be carried out at the end of the two weeks. Together we can make a difference! remember
Slide 8: global warming EXTENSION If appropriate, you could explain in more detail what causes climate change: What causes climate change? There is strong evidence that this climate change cannot be explained by natural causes alone. So what is happening? In the Earth’s atmosphere are gases called greenhouse gases . These gases let sunlight and heat in, but only let some of the heat back out. They soak up heat and send it back towards the Earth, making it warm enough for people, other animals and plants to live on. This is called the greenhouse effect because it works the same way a greenhouse does – letting in sunlight and trapping the heat inside. The more greenhouse gases there are in the atmosphere, the more heat that gets trapped. This causes the temperature to go up. So global warming is being caused by an increase in the amount of greenhouse gases. Where do these extra greenhouse gases come from? They are being made by us: humans. The greenhouse gas we release most of is carbon dioxide (CO2). CO2 is produced when fossil fuels like coal, oil and gas are burned to make energy. Fossil fuels are burnt at power stations to make electricity, and used as fuel to power planes, trains and cars. About half of CO2 emissions in the UK come from what individuals do – for example, using energy in the home for heating and electricity, or driving vehicles.
What actions can you all take to use less energy at school?
