2.  Energy use has
changed a great deal
since people relied
solely on the sun,
their own strong
bodies or animals as
energy resources.

3. Long ago, people
learned how to use
water power to
turn paddle wheels
and wind power
for transportation
and irrigation.

4. People learned to
use the chemical
energy stored in
materials like
wood to cook and
heat their homes.

5.  But machines and
technologies
introduced during
the Industrial
Revolution of the late
18th century required
the use of other
energy resources,
especially fossil fuels.

6. Fossil fuels like
coal, oil and
natural gas are
considered to be
nonrenewable
energy resources.

7. PROBLEMS CAUSED BY OVER
CONSUMPTION OF ENERGY
HEALTH
PROBLEMS
HIGHER GLOBAL
TEMPERATURES
DAMAGE TO
PLANTS

8. Other problems from the pollution from
burning fossil fuels:
 Lead poisoning has been shown to affect the development
and progress of children living near motorways
 Dust and gases in the air can lead to smog above large
industrialised cities
 A hole is developing in the ozone layer which will not filter
out harmful ultra-violet rays from the Sun

9. What are the problems with global
warming?
The average
temperature of
the Earth will rise
This can lead to
droughts

10. Extremes of
weather will
occur like
hurricanes and
storms

11.  Our fossil fuel
reserves formed over
millions of years from
decaying plants and
animals.
 As we use them up,
they will not be
replenished in our
lifetimes.

12. HOW CAN WE HELP
 UNPLUG ELECTRONIC
DEVICES
 USE ENERGRY SAVING
LIGHT BULBS
 TURN OFF LIGHTS
 CLOSE THE FRIDGE
 TURN OFF THE WATER

13. UNPLUG ELECTRONIC DEVICES
Do not leave
the television
or stereo on if
you are not
using it.

14. USE ENERGRY SAVING LIGHT BULBS
These last a
long time and
use much less
energy than
other light
bulbs.

15. TURN OFF LIGHTS
 Turn off the lights
in your bedroom
when you leave.
Make sure you turn
off all the lights in
the house when you
out
 Turn off the lights if
no one is in a room

16. CLOSE THE FRIDGE
Do not leave the
fridge door open
because the
things inside
warm up and
fridges use a lot of
energy to make
them cold again

17. TURN OFF THE WATER
 Using simple water
conservation techniques
can help cut your water
usage by more than half. If
you commit just a little
extra effort each day you
alone can make a
difference
 Turning off the water when
you are brush your teeth is
a great way to start
conserving energy
