Indoor
Turn off the lights in any room you're not using
Use natural lights
Use CFL Lamps in place of GL Lamps
Use electronic ballast

12. Comparison -Efficacy Good Best Better T12, 38 mm 60 Lm/W T8, 26 mm

13. Lighting Distribute – Different Lighting Zone
Studying, stitching, Watching TV etc
Wall colours – Light colours
More reflectivity
Regular cleaning of lamps
20-30% more light output

14. Suggested Measures to improve energy efficiency
Refrigerator
Consumes 20% of total energy
Eg., Cost of operating 315 Lts refrigerator is Rs 4000/Yr
Select energy efficient equipment
Set thermostat at correct temperatures
Don't keep your refrigerator or freezer too cold
In 24 hours, only around 8 Hours compressor ON – remaining 16 hours maintains cool
Minimize number of openings
Plan your operation

15. Suggested Measures to improve energy efficiency
Bring to room temperatures
Cool to room temperature

16. Suggested Measures to improve energy efficiency
Refrigerator
Regularly defrost manual-defrost refrigerators and freezers
Motor load will increase
Leave enough space between your refrigerator and the walls or cabinets
Air can circulate around the condenser coils
Trapped heat increases energy consumption

17. Suggested Measures to improve energy efficiency
Refrigerator
Set temperatures at optimal level
Food compartment between 36° and 40° F
Freezer between 0° and 5° F
Make sure your refrigerator door seals are airtight
Check by inserting paper
If you can pull the paper or bill out easily, the latch may need adjustment or the seal may need replacing

18. Suggested Measures to improve energy efficiency
Refrigerator
When away for long time – Empty refrigerator and switch-off
Clean condenser 3-4 times in a year
Close food container lids – absorb moisture in the food item

19. Fans & A.C’s
Electronic regulators – energy efficient compared to switching type
Exhaust fan in bathrooms & kitchens – remove heat
Air coolers ¼ power compared to A.C’s – Where humidity is less
Electronic thermostat controllers
Clean A.C filter once in a month
Trees around house – Equivalent to A.C
10 – 15 deg C less than ambient

20. Electric Iron
Iron – Light weight
450
2 hours 15 minutes
Iron – Heavy
750
1 hour 20 minutes
While drying clothes – drain water opening them widely and shake them briskly
Minimum wrinkles – shorter ironing period
While ironing – Initially set low temperature
Select clothes like nylon, polyester
Increase temperature
Cotton clothes
Requires high temperature – results in loss
Switch-off power – Just before completing
Continue ironing
Possibly Iron all the clothes at a time

21. Time needed to consume 1 Unit (kWh) of electricity
Washing Machines
Appliance
Energy Used (Watts)
Time needed to consume 1 Unit (kWh) of electricity
Washing Machine – without drier
230
4 hours 20 minutes
400
2 hours 30 minutes
Always wash only with full load
Use the correct amount of detergent
Too many bubbles make your machine work harder and use more energy

22. Washing Machines
Up to 60 percent of the cost of washing clothes comes from heating the water
Use hot water only for very dirty clothes, and always use cold water in the rinse cycle
Apart from Monsoon and chilly weather – avoid using the dryer as it consumes more power

23. T.V & Audio/Video
For certain reasons (like attending telephone) TV or radio volume is lowered, Restore the volume / do not forget to switch-off
Don’t keep the TV in remote activated system in night – The circuit consumes minimum 15 Watts of power
Long holiday / tour – safe to de-plug the cords

24. Water Pump Power Consumption – ¼ hp to 1 hp
Annual operating expenses > Rs.5000/yr
Use correct capacity and head
Use ISI branded pumps
Ensure minimum bends I piping
Keep regular check on water leakages
Use auto on-off switch with level of the tank

25. Fuel Savings in Cooking
Complete all work like cleaning rice, cutting vegetables
Before starting stove – Keep all appliances ready
Use correct size burner depending on the vessel size
Un necessary Larger burner – waste of 135 gm gas
Use only desired amount of water for cooking
More water – additional gas and drains away nutrients
65% high fuel consumption
While boiling close the vessel with lid
10% gas savings
Copper bottom vessel
20% fuel savings and faster

26. Fuel Savings in Cooking
Flame colour is not blue – cleaning of burner required
Kitchen window – blowing air directly towards stove
20% Wastage
Electrically heated stove consumes more power compared to gas stove
On electric stovetops, use flat-bottomed pans that make full contact with the element
A warped or rounded pan will waste most of the heat

27. Micro wave Oven
Microwaves ovens use very high-frequency radio waves to penetrate the surface of food to heat water molecules inside
Consumes 50 % less energy than conventional ovens
Not Suitable for Large size food
Always remember the more you spend in the kitchen, the more energy you are consuming

28. Solar Water Heating Heating - Consumes 35% of total energy
Replace Geyser
Best option
Gaining tremendous popularity
Savings for average household – Rs.6000 per year

29. Idle operation of Electrical Appliances
Biggest loss of energy
TV, Audio Systems,Telephone answering machines
A small compact audio unit can draw 9 watts while it's ostensibly turned off
Audio Player used for an hour and kept switched on whole day
93 percent of a stereo's energy use occurs when the unit is not turned off!!
What is the Solution?
Unplug the appliances when not in use!!!
