Energy Conservation Shahid Waseem
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.
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.
Cost 
Why save Energy ? 
Energy prices are rising every year
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
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.
Remember 
 “We do not inherit the 
earth from our parents, we 
borrow it from our 
children” – 
Chief Seattle
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
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
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
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
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.

Hinweis der Redaktion

  1. ESOS is new piece of EU legislation which requires member states to introduce a mandatory Programme of energy audits for 'large enterprises'. This means over 7000 of Britain's biggest companies will be required to comply – with the initial audits to be undertaken by 5th December 2015.
