The document discusses how energy use has changed over time from relying solely on natural sources like the sun and human/animal labor, to utilizing water, wind, and burning materials like wood. The Industrial Revolution introduced widespread fossil fuel use which are non-renewable resources that are being depleted. Problems caused by overconsumption of energy and burning fossil fuels include health problems, higher global temperatures, damage to plants, pollution-related issues like lead poisoning and smog, and a developing hole in the ozone layer. Global warming may lead to droughts, extremes in weather like hurricanes and storms. The document provides tips to help conserve energy such as unplugging devices, using energy-saving bulbs, turning off lights when not in

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
