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

Minimize number of openings

Plan your operation

19/32



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


20/32



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 outeasily, the latch may need adjustment

or the seal may need replacing


21/32


Washing Machines

Always wash only with full loads

Use the correct amount of detergent

Too many bubbles make your

machine work harder and use more

energy

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


22/32


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


23/32


Cooking Tips

Microwave ovens use around 50percent less energy than

conventional ovens

With conventional ovens, minimize

the preheating time

Unless you're baking breads or pastries,

you may not even need to preheat


24/32


Cooking Tips

Don't open the oven door

too often when checkingyour food Each opening drops

temperature by 25C Turn off electric burners

several minutes before the

allotted cooking time.


25/32


Cooking Tips

On electric stovetops, use flat-bottomed pans that make fullcontact with the element A warped or rounded pan will waste

most of the heat

When cooking on a gas burner,use moderate flame settings toconserve natural gas

Remember that a blue flamemeans your gas stove is operating

efficiently Yellowish flame is sick and needs

cleaning


26/32


Solar Water Heating

Consumes 35% of total energy

Replace Geyser

Best option

Gaining tremendous popularity

Savings for average household Rs.6000 per year

27/32


Idle operation of ElectricalAppliances

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!!!
