© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry Suggested Measures to improve energy efficiency Bring to room temperatures Cool to room temperature
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry Electric Iron 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 Iron – Light weight4502 hours 15 minutes Iron – Heavy7501 hour 20 minutes
© Confederation of Indian Industry Washing Machines Always wash only with full load Use the correct amount of detergent Too many bubbles make your machine work harder and use more energy ApplianceEnergy Used (Watts) Time needed to consume 1 Unit (kWh) of electricity Washing Machine – without drier 2304 hours 20 minutes Washing Machine – without drier 4002 hours 30 minutes
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry 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
© Confederation of Indian Industry Solar Water Heating Heating - Consumes 35% of total energy Replace Geyser Best option Gaining tremendous popularity Savings for average household – Rs.6000 per year
© Confederation of Indian Industry 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!!!
