earth from our parents,
we borrow it from our
children” –
Chief Seattle
3. Definition -Energy conservation is the practice of
decreasing the quantity of energy used. It may be achieved
through efficient energy use, in which case energy use is
decreased while achieving a similar outcome, or by reduced
consumption of energy services. Energy conservation may
result in increase of financial capital, environmental value,
national security, personal security, and human comfort.
Individuals and organizations that are direct consumers of
energy may want to conserve energy in order to reduce
energy costs and promote economic security. Industrial and
commercial users may want to increase efficiency and thus
maximize profit
4. Industrialised countries need large
amounts of energy
Most of this energy comes form fossil fuels
which are burnt in power stations,
factories, homes and vehicles
These fossil fuels formed millions of years
ago, and are non-renewable
Once the fossil fuels have been used up
there will be no more to replace them
5. Energy use has
changed a great deal
since people relied
solely on the sun, their
own strong bodies or
beasts of burden as
energy resources.
6. Long ago, people
learned how to use
water power to turn
paddle wheels and
wind power for
transportation and
irrigation.
7. People learned to use
the chemical energy
stored in materials like
wood to cook and heat
their homes.
8. But machines and
technologies
introduced during the
Industrial Revolution of
the late 18th
century
required the use of
other energy
resources, especially
fossil fuels.
9. Fossil fuels like coal, oil
and natural gas are
considered to be
nonrenewable energy
resources.
10. 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.
11. With the modern world
depending upon coal, oil
and gas for a majority of its
energy needs and the
prediction that the world
will nearly double its need
for energy resources in
several decades, it is
important to conserve
energy and to investigate
alternate energy resources
12. There are many renewable
energy sources that are
alternatives to fossil fuels,
but some are not without
controversy.
For instance, nuclear
power is used to generate
about 25 percent of the
world’s electricity, but it
has inherent risks,
especially in the disposal of
radioactive waste.
13. Hydroelectric plants use running water to generate
electricity, however they may flood nearby lands and can
disrupt the normal flow of water, both of which negatively
affect the environment.
14. Wind power is
increasingly being used
as a clean source of
renewable energy.
Turbines harvest wind
on wind farms and
generate electricity.
15. Solar power is a promising, renewable energy
resource than can be turned into electricity, and it is
used in many toys and even home heating.
16. Many other alternative
energy sources like
geothermal power, which
draws upon the earth’s
natural heat, and biomass,
which produces an
alternative to gasoline, are
being considered in the
movement away from
fossil fuel dependence.
17. In our everyday lives, we can also work to conserve energy.
Insulating, turning off lights and only using appliances like dishwashers when
they are full are just some of the ways people can limit energy use in their
homes.
Also, carpooling, bicycling, and taking public transportation are effective
energy-saving ideas.
18. The earth’s inhabitants
must take a serious
look at energy
resources, use and
conservation.
19. Quick Tips to save energy in the home
Improving a homes air tightness can reduce
consumption by 15-40%
Front loading washers use 50% less electricity
and up to 50% less water
Programmable thermostat – 2 for 1
Microwave oven’s use up to 75% less
Laptop computers use 90% less
Buying Energy Star appliances can save 25%+
20. Reduce, Reuse, Recycle – Part of an effective
conservation program
Energy Audit – Identify your “best bets”
Energy Calculator – Identify those areas that
use the most energy – Remember home
heating accounts for 60%+ of your energy
consumption with hot water next!
Make a plan, set some goals
Involve the whole family
21. Increase everyones’ understanding of the
benefits of energy efficiency
Make the link between actions and behaviour
by individuals and potential savings
Motivate users to modify behaviour
Share the goal of reducing energy
consumption and saving money
22. “The kind of thinking that has got us
into this situation is not the kind of
thinking that will get us out”
- Albert Einstein
