3. What is Energy Efficiency?
 Using less energy
 Providing the same service

4. Examples
 Using fluorescent bulbs or natural skylights instead
of incandescent light bulbs.

5. Examples
 Modern appliances, such
as, freezers, ovens, stoves, dishwashers, and clothes washers
and dryers, use significantly less energy than older appliances.

6. Energy efficient Icons

7. Motivations to improve energy efficiency
 Reducing energy use reduces energy costs
 Financial cost saving to consumers
 Reduces carbon dioxide
 Improves energy efficiency in buildings
 Improves industrial processes and transportation
 Helps control global emissions of greenhouse gases.

10. Reduces carbon dioxide

11. Energy efficiency in buildings

12. How to improve
 Tight building design includes energy efficient
window, well-sealed doors, additional thermal
insulation of walls can reduce heat lose 25-
50%.
 Dark roofs
 Green building design

13. Industrial processes

14. Ways to improve:
 Generate steam through heat produced during
production of electricity
 Co-generation converts up to 90% of the fuel
into usable energy
 Advance furnaces can operate at higher
temperature using less fuel
 Better process control and better maintenance
practices

15. Improvedtransportation

16. Ways to improve?
 Improved aerodynamics of vehicles
 Reduce weight by using composite materials
 More advanced tires
 Replacing a clogged air filter can improve a car fuel
consumption up to 10%
 Energy efficient vehicles may reach twice the fuel
efficiency of the average automobile.

17. Energy efficient vehicle
 For e.g. Mercedes Benz Bionic is the latest design
approved which provides 84% of fuel efficiency.

18. Emissions of greenhouse gases

19. Sustainable energy policy
 Energy efficiency and renewable energy are said to
be the twin pillars of sustainable energy policy and
are high priorities in the sustainable energy hierarchy.

20. Renewable energy
 Any energy resource that is naturally
regenerated over a short time scale and
derived directly from the sunlight, wind,
rain, tides, waves and geothermal heat.

21. Renewable energy

22. Renewable energy

23. Sustainable energy
 Energy that is produced using the sun, wind, etc., or
from crops, rather than using fuels such as oil or coal

24. Sustainable energy

25. Basics of Energy Use
 Energy is a part of everything we do.

26. Efficiency of Energy Conversion
 If we are more efficient with the energy we
already have there will be less pollution, less
reliance on foreign oil and increased domestic
security.

27. Less reliance on foreign oil

28. Less pollution

30. Illustration
 An electric motor consumes 100 watts (a joule per
second (J/s)) of power to obtain 90 watts of
mechanical power. Determine its efficiency ?
= 90 W x 100 = 90 %

31. Vehicle Efficiency – Gasoline Engine
25% Of the gasoline is used to propel a car, the rest is
“lost” as heat. i.e an efficiency of 0.25

32. Energy-efficient products
 Products/appliances can account for up to 30
per cent of your home energy use. As our reliance
on products/appliances increases and energy prices
are also on the rise, choosing energy-efficient
appliances becomes more important. The national
standards for energy efficiency are improving the
environmental performance of appliances all the
time, so upgrading to a more efficient appliance can
save you energy and money.

33. Energy Efficient Products
 It's not only about having the right
product—how you use appliances in your
home can make a big difference. For
example washing your clothes with warm
water can save up to 10 times more energy
than a cold wash

34. WHATIS YOUR AVERAGE MONTHLY
ENERGY BILL?
 Heating and cooling costs the average
homeowner about $1,000 per year – nearly half
the home’s total annual energy bill. Depending on
where you live, replacing your old heating and
cooling equipment with energy efficient
products can cut your annual energy bill by more
than $200.

35. Think long term.
 Many of the most energy-efficient products cost more initially,
but they'll save you money in the long run. Expect to keep
most major appliances between 10 and 20 years.
 A more efficient appliance soon pays for itself; lower monthly
utility bills over the lifetime of the appliance will more than
offset a higher purchase price.

36. Think long term.
 In addition, the latest resource-efficient clothes
washers and dishwashers not only save electricity,
they also use a lot less water and can reduce your
water bill.
