What is energy and the uses of energy
The difference between renewable and non-renewable energy
Why we need to save energy
How we can save energy and be more energy efficient
How to measure energy savingsLearning Objectives
Fossil fuels are sources of non-renewable energy. Most of the electricity in the UK is produced by burning fossil fuels in large power stations.
They take millions of years to create and will soon run out. Can you name the fossil fuels?NON-RENEWABLE ENERGY
Renewable energy are sources which can be reproduced over and over again. Renewable energy sources are greener and better for our planet than Non-renewable energy sources. Can you think of any?RENEWABLE ENERGY
Nuclear power stations creates about 18% of the UK’s electricity from a small amount of element called Uranium
There are no CO2 emissions from nuclear power stations
Some of the waste created contains radiation which must be kept safe for thousands of years.NUCLEAR ENERGY
Why is it important to save energy? electricity from a small amount of element called UraniumOur planet needs YOU!
To SAVE the environment electricity from a small amount of element called Uranium
To Save our planet’s Non-renewable energy sources
3. To SAVE moneyThe reasons to SAVE energy
Everyday, when we travel in cars and use electricity and heating in our homes, we release a gas called carbon dioxide (CO2).
When CO2 is released, it pollutes the atmosphere.
CO2 is a major contributor of the green house effect and speeds up the changes in our climate .Did you know?
CO heating in our homes, we release a gas called carbon dioxide (CO2 traps heat in the atmosphere, similar to a warm blanket. We need this blanket to stop the Earth from freezing.
However, too much CO2 in the atmosphere makes the planet too hot and creates what is known as the Greenhouse Effect.
The long term result is Climate Change (or Global Warming) – changes in world temperatures and weather patterns over a long period of time.What is climate change?
Who would like to come to the front to demonstrate this?
Ice melting and sea level rising heating in our homes, we release a gas called carbon dioxide (CO.Negative Effects: Climate Change
More floods due to heavy rainfall and strong winds in countries like Wales.Negative Effects: Climate Change
Diseases, such as malaria, that appear in hot climates are spreading as mosquitoes move to colder climates.Negative Effects: Climate Change
Plants and animals are becoming extinct spreading as mosquitoes move to colder climates.
(up to 1/3 could disappear by 2050)Negative Effects: Climate Change
Oceans getting warmer and turning too acidic.
Fossil Fuels are running out spreading as mosquitoes move to colder climates.
40 years of oil left
65 years of gas left
200 years of coal left2. To SAVE non-renewable energy sources
Save energy = Save money! spreading as mosquitoes move to colder climates.
Together we can save millions of £££ on our heating and electricity bills by not wasting energy.3. To SAVE money
Ysgol Ein Harglwyddes produced 44 tonnes of CO spreading as mosquitoes move to colder climates.2 in 2009
This is enough CO2 to fill 264 double-deckers
44 hot air balloonsIs your school contributing to climate change?
Close doors and windows to prevent the heat from escaping! spreading as mosquitoes move to colder climates.Close them!
Every month, note your school’s electricity and gas meter readings to find out if your school is using less energy.
Send your readings to the suppliers (British Gas / Corona Energy)Have you saved energy?
