Green Collar Careers - Laundry
With laundry appliances consuming an average of 6.7% of the
electricity used there are other variances to consider which may
increase or decrease that factor. Homes with toddlers or teenage
tend to have a much heavier laundry demand.
Electricity is consumed
by operating the washer heating the water (if water is electrically
heated) and running the dryer (if an electric dryer).
Simple common sense rules go a long way in the laundry room.
Washing Machines are sized to operate most efficiently with a specific
load size. Too small of a load and energy is wasted. Too
large of a load and energy is wasted by loading down the motor and in
the drying cycle.
Not all loads will require the full cycle of
cleaning. A light duty cycle typically takes about 2/3's the
power for a heavy duty cycle.
Hot water cycles do very little to
remove soil although they help a little bit with disinfecting.
The emphasis is "little bit" as water above 110° is a little more
likely to break "bonds" of some bacteria to fabrics. To be more
effective then 110° provides requires much more heat.
of the best practices is to post set of simple large text guidelines
for laundry and washing machine settings near the washing machine -
that goes a lot further then most people expect.
Just like water heaters, natural gas is the most cost effective fuel.
Electric dryers typically consume 4-5% of the total electric power,
and that will vary with the occupant’s lifestyle. Most people tend to
overuse dryers simply because they take for granted the task a dryer
Most dryers have settings for “dryness level”. Choosing the lowest
level will save about 1-2% of the total power usage.
