Energy efficient products (1)

In this presentation some of the energy efficient products are being presented and some of the manufacturing techniques and processes are being discussed to create energy efficient products,

1. ENERGY EFFICIENT PRODUCTS Presented to: Mam Ayesha Sir Sajid Presented by: Saira Tariq Saddam Jan Amna Shabbir

2. What is Energy E fficiency? Using less energy Providing the same service

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

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

5. Energy efficient Icons

6. 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.

7. Reduces energy costs

8. Financial cost saving

9. Reduces carbon dioxide

10. E nergy efficiency in buildings

11. 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

12. Industrial processes

13. 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

14. Improved transportation

15. 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.

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

17. E missions of greenhouse gases

18. 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.

19. 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.  

20. Renewable energy

21. Renewable energy

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

23. Sustainable energy

24. Basics of Energy Use Energy is a part of everything we do.

25. 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.

26. Less reliance on foreign oil

27. Less pollution

28. Energy efficiency

29. 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 % 100 W

30. 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

31. Energy-efficient product s Products/a ppliances 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 .

32. 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

33. WHAT IS 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.

34. 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.

35. 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.
