Why Energy savings?
Long term financial rewardsPotential to save up to 50%
National interest
Occupant comfort
Reduce pollution and
Conserving our natural resources

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

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!!!
