Why Save Energy?
What are fossil fuels?
Coal, oil and natural gas are fossil fuels. They are called “fossil fuels” because they were formed by fossilized remains of dead plants and animals under pressure and heat beneath the Earth’s crust over hundreds of millions of years. Today they are used by people to make electricity in power stations.
What is the greenhouse effect?
Burning fossil fuels emits gases such as carbon dioxide. As carbon dioxide and other gases build up in the Earth’s atmosphere, more of the sun’s heat is trapped. We call this the “greenhouse effect” because the carbon emissions which build up in our atmosphere trap heat in a similar way to glass trapping heat in a greenhouse.
What is global warming?
The greenhouse effect is causing the average temperature of the Earth’s surface to rise, which is referred to as global warming. Scientists think that climate change could also increase the risk of drought and coastal flooding.
What can we do?
If we can use energy more efficiently, we will reduce our overall electricity consumption and therefore decrease carbon emissions. Find out more about how to reduce your household carbon emissions. Remember that you can also save energy at school , at work and when travelling
