This presentation is aimed at understanding basic concepts of energy, how it is used and conserved.

1. Energy Conservation Shahid Waseem

2. Definition of Energy conservation
 Energy Conservation: is
any behavior that results
in the use of less energy.
Turning the lights off
when you leave the room
and recycling aluminum
cans are both ways of
conserving energy.

3. What is Energy ?
 In its simplest form
Energy is the ability to
do work
 The universe is a
combination of the
energy and matter
 Matter is a substance
and energy is the
mover of substance
 Energy cannot be
created or destroyed;
it may be transformed
from one form into
another, but the total
amount of energy
never changes.

4. Cost
Why save Energy ?
Energy prices are rising every year

5. Climate Change
Why save Energy ?
 Change in the earth’s climate
causing an increase in temperature
known as “Global Warming” Direct
cause from Human Activity Global
temperature has risen and is on a
steep incline unless we take
immediate actions to reduce our
C02 emissions

6. Climate Change
 “Climate change poses a bigger threat to the planet than
terrorism” - The UK government's chief scientific adviser, Sir David
King.
 Concentrations of the greenhouse gases carbon dioxide and
methane in the atmosphere are higher now than at any time in the
past 650,000 years.
 The rates of increase are absolutely exceptional: the CO2
concentration is rising 200 times faster than at any time in the last
650,000 years.

7. Remember
 “We do not inherit the
earth from our parents, we
borrow it from our
children” –
Chief Seattle

8. Behavior Change
 Reduce the amount of waste we produce
 Change our energy usage behavior to
conserve more energy
 cycling, and taking public
transportation are effective energy
saving ideas
Energy efficiency
 Improve our technology to improve
energy efficiency
Solution

10. Energy efficiency
 Energy Efficiency is the use of
technology that requires less
energy to perform the same
function. An LED light bulb that
uses less energy than an
incandescent bulb to produce
the same amount of light is an
example of energy efficiency.
However, the decision to
replace an incandescent light
bulb with a compact fluorescent
is an act of energy conservation

12. Efficiency vs. Conservation
Efficiency
 Energy efficiency involves
the use of technology that
requires less energy to
perform the same function.
 Focuses on the equipment
or machinery being used
 One example is installing
LED light bulbs throughout
the house
Conservation
 Energy conservation
includes any behavior that
results in the use of less
energy.
 Focuses on the behavior of
people
 One example is using day
lighting through windows
rather than turning on the
lights

13. Global response to climate change
There are legal obligations the governments around the world have
introduced in order to combat the climate change
 CRC is a mandatory reporting and pricing scheme to improve
energy efficiency in large public and private organizations
 ESOS Energy Audits
 EU emission trading system puts price o green house gas emissions
to create financial incentives for industry and businesses to reduce
emissions
 Greet Deal lets businesses and other non-domestic organisations
pay for some or all of the cost of energy-saving property
improvements through savings on their energy bills over time

15. What are we doing about it ?
From the energy use chart it can be seen that the two major
energy uses are lighting and cooling/heating
 In large buildings heating and cooling loads are on on demand
and often controlled by Building Management System
 New intelligent LED lights can save a huge amount of energy.
These lights are controlled by sensors and they dim or switch
off when not needed.
