SAVING ENERGY

By Marial Edwards

learning objectives
You will understand:

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 savings

Learning Objectives
non renewable energy
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

Coal

Gas

Oil

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

SOLAR ENERGY

BIOMASS

GEOTHERMAL

WIND POWER

HYDRO ELECTRIC

nuclear 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
the reasons to save energy
To SAVE the environment

To Save our planet’s Non-renewable energy sources

3. To SAVE money

The reasons to SAVE energy
did you know
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?
what is climate change
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?

negative effects climate change4
Plants and animals are becoming extinct

(up to 1/3 could disappear by 2050)

Negative Effects: Climate Change

Oceans getting warmer and turning too acidic.

2 to save non renewable energy sources
Fossil Fuels are running out

40 years of oil left

65 years of gas left

200 years of coal left

2. To SAVE non-renewable energy sources
3 to save money
Save energy = Save money!

Together we can save millions of £££ on our heating and electricity bills by not wasting energy.

have you saved energy
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?
