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


What is energy what have you got at home or at school that uses energy
What is energy? What have you got at home or at school that uses energy?


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


Our planet needs you

Why is it important to save energy? electricity from a small amount of element called Uranium

Our planet needs YOU!


The reasons to save energy

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 money

The reasons to SAVE energy


1 to save the environment
1. To SAVE the environment electricity from a small amount of element called Uranium


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

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?


Negative effects climate change

Ice melting and sea level rising heating in our homes, we release a gas called carbon dioxide (CO.

Negative Effects: Climate Change


Negative effects climate change1

More floods due to heavy rainfall and strong winds in countries like Wales.

Negative Effects: Climate Change


Negative effects climate change2

More drought already seen in several countries on the Equator.

Negative Effects: Climate Change


Negative effects climate change3

Diseases, such as malaria, that appear in hot climates are spreading as mosquitoes move to colder climates.

Negative Effects: Climate Change


Negative effects climate change4

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.


2 to save non renewable energy sources

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 left

2. To SAVE non-renewable energy sources


3 to save money

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


Is your school contributing to climate change

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

OR

44 hot air balloons

Is your school contributing to climate change?


Switch them off
Switch them off! spreading as mosquitoes move to colder climates.


Hot and bothered
Hot and bothered! spreading as mosquitoes move to colder climates.

REMEMBER

18°C


Close them

Close doors and windows to prevent the heat from escaping! spreading as mosquitoes move to colder climates.

Close them!


Don t waste it
Don’t waste it! spreading as mosquitoes move to colder climates.


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?


Www sbarciafflic org
www.sbarciafflic.org readings to find out if your school is using less energy.


Climate challenge
CLIMATE CHALLENGE readings to find out if your school is using less energy.

Choose a Climate Crime Card.

Can you guess the climate crime?
