4. What is energy?
 Energy is the ability to do work.
 Energy is in everything
 Energy can be neither created nor destroyed but only changed from one
form to another. This principle is known as the conservation of energy or
the first law of thermodynamics.
 Energy comes in different forms:
• Heat (thermal)
• Light (radiant)
• Motion (kinetic)
• Electrical
• Chemical
• Nuclear energy
• Gravitational
 People use energy for everything from walking to sending astronauts into
space. There are two types of energy:
• Stored (potential) energy
• Working (kinetic) energy

6. SHORT TERMS
• Energy conservation: Is the term used for reducing the
consumption through using less energy service. Energy
conservation is not about making limited resources last
longer, but it is a process of doing nothing more than
delaying a crisis until we finally run out of all our energy
resources.
• Energy Efficiency: The phrase energy efficiency is often
used to describe any kind of energy saving measure,
though technically energy efficiency is different from
energy conservation.
• Energy Management: Is a term used for saving or
reducing the use of energy in businesses, public sector
or government organizations and homes. It is the art of
using optimum energy to maximize profits and minimize
costs thereby improving the economic competitiveness.

8. Energy sources can be categorized as
renewable or nonrenewable
• When people use electricity in their homes, the
electrical power is probably generated by burning
coal or natural gas, by a nuclear reaction, or by a
hydroelectric plant on a river, to name just a few
sources.
• When people fill up a car’s gasoline tank, the
energy source is petroleum (gasoline) refined
from crude oil and may include fuel ethanol
made by growing and processing corn. Coal,
natural gas, nuclear, hydropower, petroleum, and
ethanol are called energy sources.

11. The chart shows the
energy sources
used in the United
States. In 2017,
nonrenewable
energy sources
accounted for about
90% of U.S. energy
consumption in
2017. Biomass,
which includes
wood, biofuels, and
biomass waste, is
the largest
renewable energy
source, and it
accounted for nearly
half of all renewable
energy consumption
and about 5% of
total U.S. energy
consumption.

12. Energy conservation
• Energy conservation is the effort made to reduce the consumption of
energy by using less of an energy service. This can be achieved either
by using energy more efficiently (using less energy for a constant service) or
by reducing the amount of service used (for example, by driving less).
• Energy conservation is a part of the concept of eco-sufficiency.
• Energy conservation reduces the need for energy services and can result in
increased environmental quality, national security, personal financial
security and higher savings. It is at the top of the sustainable energy
hierarchy.
• It also lowers energy costs by preventing future resource depletion
12

13. • Energy can be conserved by reducing wastage
and losses, improving efficiency through
technological upgrades and improved operation
and maintenance.
• On a global level energy use can also be reduced
by the stabilization of population growth.

14. Key steps of an energy management
• A successful energy management involves
following key steps.
get commitment and appoint an energy manager
understand the issues
plan and organize
develop an action plan
involve your staff
control, monitor and report
14

15.  get commitment and appoint an energy manager
• The first step is to make sure that senior management understands
the business benefits of an energy strategy and supports the
proposed energy-saving measures. Appointing an energy manager
demonstrates that the business takes its energy-saving goals
seriously. The energy manager's role is to:
• Lead the energy team in their energy-saving actions
• communicate and emphasize to colleagues the importance of the
energy strategy
• The energy manager needs experience and training to be effective -
relevant professional qualifications are available. Depending on the
size of your organization the role might be full or part time.
15

16.  understand the issues
• To manage energy use effectively you need to have a clear understanding
of:
• how your business is currently using energy
• how your energy usage compares with other businesses
• attitudes within your business towards adopting energy-saving measures
• The Carbon Trust has produced guidance for businesses on implementing
an effective energy management strategy. This includes an energy matrix
to help you assess your current performance.
 plan and organize
• Start by carrying out an energy survey to see where you can make energy
savings. Use all the information you gather to produce an energy policy
and identify long, medium and short-term energy-saving targets.
16

17.  develop an action plan
• Once you have identified your targets, draw up an action plan outlining the
practical steps your business will take to achieve your goals. Give individuals
responsibility for specific tasks.
 involve your staff
• It's very important to get support for the energy strategy from:
• key decision makers
• senior management
• staff at all levels of the business
• Carrying out training and highlighting the strategy's benefits all help to boost staff
participation.
 control, monitor and report
• Monitor your performance regularly to check that you're making progress towards
your energy-saving goals. Put in place procedures to make sure your systems will
carry on operating efficiently and continue to make savings in the future. Let staff
know how progress towards achieving targets is going - this helps to keep them
motivated.

18.  Use energy-efficient light bulbs
• Buy compact fluorescent light (CFL) bulbs. They use
a whopping 75 per cent less energy than traditional
incandescent bulbs. While CFL bulbs cost a little
more, you’ll actually save money - the bulb lasts a
lot longer and doesn’t use as much energy.
 Turn down your thermostat
• Reduce the temperature setting on all your heating
and air-conditioning units, plus your hot-water
system by two to three degrees. Never leave
heaters on all night – instead heat your bed with a
hot water bottle or an electric blanket for a few
minutes. This, along with your own body heat,
flannel sheets and a thick doona will make you feel
nice and warm, even if the air temperature in the
room is cold.

19.  Use cold water in your washing machine
• If you do this and also run your machine on a quick cycle you'll
definitely reduce your home’s energy bill. Also consider buying a
front-loading machine - they use up to 50 per cent less energy than
top loaders. And choose models with a high energy star rating.
 Fix your windows
• Drafty, thin window panes can let a huge amount of heat escape
resulting in a higher winter power bill. Consider buying high-
performance windows or getting double glazing. If you can’t afford
this, then make sure there are no leaks along the base of the
window by placing a draft stopper such as a door snake along the
rim. You can also insulate your windows by sticking bubble wrap to
the panes, which is surprisingly effective. You won’t enjoy much of
a view but you’ll save money!
19

20.  Plant it
• If you’re thinking long-term, install trees and shrubs
around the outside of your house. The shade they
provide will make the house cooler in summer. And if
you plant a fast-growing shrub such as a lilly pilly
outside windows, you’ll have a good windbreak in no
time, helping to keep cold air out in winter.

21. Some of the practical methods and technologies for energy
conservation and energy management are:
• Using Smart Grids: these grids improve efficiency by using
technology to optimize the production and distribution.
Through a combination of distributed resources, interactive
technologies, renewable energy, two-way communications, and
dynamic utilization, they provide businesses and consumers
with information that allows them to alter their consumption
based on supply, demand, and pricing. That improves the
reliability and flexibility of energy use.
21

22. • Installing CFL lights: trying to
replace the incandescent bulbs with
CFL lights. CFL bulbs cost more
upfront but last 12 times longer
than the regular bulbs and will not
only save energy but over time it is
cost effective.
• Using maximum daylight: turning
off the lights during the day and
using daylight as much as possible
will reduce the burden on the local
power grid and will save a good
amount of money in the long run. 22

23. • Getting the energy audit done: one of the primary ways to
reduce energy usage is to conduct an energy audit. It is
mostly done by a panel of trained professionals for
analyzing the energy use and flow for energy in a building,
process or systems to reduce the amount of energy input
into the system without affecting the output. The recent
development of Smartphone apps will help the consumers
to get their energy audit done at home.
• Building technologies and smart meters allow the energy
users, both business and residential to see graphically the
impact their energy use can have in their workplace.
Advance real time metering allows people to save and
conserve energy by their actions.
23

24. • Energy Tax: Some countries employ energy or carbon
taxes to motivate the energy users to reduce their
consumption. Carbon taxes allows consumptions to
alter. Nuclear and other alternative methods of energy
can help reduce environmental impacts. Taxes on all
energy consumption helps reduce energy use across
the board, while reducing the environmental
consequences arising from energy production.
• Switching off the electric appliances when not in use.
• Drive less, walk more and carpooling: is yet another
way of conserving energy. This will not only reduce the
carbon footprint but will also keep us healthy.
24

25. • Install energy efficient windows
• Windows are significant source of
energy waste, which can amount to 10-
25% of your total heating bill. To
prevent heat loss through your
windows, you can replace single-pane
windows with double-pane ones.
• Insulate your home
• Insulation plays a key role in lowering
your utility bills through retaining heat
during the winter and keeping heat out
of your home during the summer.
25

26. Why conserve energy in the first
place?
• Energy conservation is important and
beneficial for many reasons. You can save
money, increase your property value, and protect
the environment all through simple energy-saving
measures. These are great benefits you can gain
from saving energy no matter your exact
motivation for conservation in the first place. By
simply taking a small step towards living a more
energy-conscious lifestyle, you can begin to enjoy
all of the perks of being energy efficient.
26

27. Conclusion
• Energy efficiency is the wave of the future. The world is quickly moving towards energy
sustainability. At the same time, the mankind is trying to re-establish the connection it
once had with nature. An energy efficient home is a personal step toward the direction
of renewable energy, environmental protection, and sustainable living. Having such a
home helps homeowners reduce their bills and provides an excellent investment.
Furthermore, energy efficiency means healthier and more comfortable living that is in
line with nature.
