You can lower your monthly energy bill and contribute to a cleaner environment without making major changes or buying expensive energy-saving gadgets. Simple changes, and thought given to energy reduction, will make a significant difference.
Dishwashing
~ If washing dishes by hand, fill one
basin with warm soapy water and the other with cold rinse water. This saves
much more water than leaving the cold water running for rinsing.
~
If you're using the dishwasher, pre-rinse dishes with cold water. Be sure
machine is full, but not overloaded.
~
Turn off automatic air-dry switch, and let dishes dry by air. If your machine
doesn't have an air-dry switch, turn off the control knob after the final
rinse and prop the door open a bit so the dishes will dry faster.
~ If
a small load, avoid using "Rinse-Hold". This uses 3 to 7 gallons
of hot water each time it's used.
~
Check the manual that came with your dishwasher
for the manufacturer's recommendations on water temperature; many have internal
heating elements that allow you to set the water heater in your home to a
lower temperature (115 degrees).
Microwave
~ Microwaves use between one-fifth
and one-half as much energy as conventional stoves.
~
Microwaves are most efficient at cooking small portions and for defrosting.
~
Food cooks faster when placed on the outer edges of a rotating tray rather
than in the center, allowing more microwaves to interact with the food.
~
Food cooks faster in a microwave as the surface-to-volume ratio increases.
When cooking potatoes, for example, thinner slices will cook faster than
cubed or quartered sections.
~ During warm weather, microwave use
minimizes radiant heat buildup from the kitchen.

Gas
Stoves,
Electric Ranges
~
Gas stoves with an electric ignition (piezo) will use 40% less gas than
one with a continuous pilot light. Burner flames on gas stoves should
be blue. If flame is yellow, the ports need to be unclogged or adjusted.
Ports can often be cleaned with a pipe cleaner.
~ When using the
oven, try to reduce the number of times you open the door while cooking.
Each time the door is opened, the stove loses about 1/4th of its heat.
~ Burner size:
Match
pot size to burner size on your stove top. Heat is lost and energy is
wasted if burner size is larger than pot size. Also, clean range-top burners
and reflectors to better reflect the heat, and save energy.
~ Use pressure cookers. They use 50-75
percent less energy than ordinary cookware.
~ On
electric stovetops, use flat-bottomed pans that make full contact with
the elements.
~ If you cook on an electric range,
you can turn off the burners or the oven before the cooking is finished,
because it will take several minutes for the burners to lose their heat.
Induction Cooktops
Induction
cooking uses 90% of the energy produced compared to only 55% for a gas
burner and 65% for traditional electric ranges.
Induction
cooking is based on magnetic fields: each ‘element’ (an induction
coil) generates a magnetic field that induces heat in steel cookware placed
on top of it. In essence, the pot
becomes the element that cooks the food, so the cooktop surface doesn’t
get as hot as other cooktops. Induction cooktops have the same instant
control as gas and are the fastest of all cooktop types to heat and cook
food. more info
Sun Ovens
Sun ovens are the most energy-efficient cooking appliance.These
solar powered ovens require no fuel yet can cook anything you can cook
in a conventional stove. Of course they must be used outdoors in the sun.
For summer cooking they also save energy by keeping your kitchen from
heating up. more info
Hybrid solar ovens are also available which have an electric backup
which allows the oven to be used when sunlight is not available. Even
when using the electric backup, these units use 75% less electricity than
conventional electric range ovens. more

Disposal
Unit
If your sink has a disposal unit, use cold water when operating. This
saves energy used to heat the water, and is more effective at removing
grease. Grease will solidify under cold water and become more easily ground
up and washed away. You can give it a quick final rinse with hot water.
Faucet
Aerator
Installing a $5 faucet aerator is the most effective water conservation
measure you can do in your kitchen. The lower flow is barely perceptible,
though it will take longer to fill large pots. Water consumption and the
cost of heating the water can be reduced by as much as 50%.

information on low-flow faucet aerators and shower heads.
Refrigerator
~
Vacuum the coils on the back
of your refrigerator twice a year to maximize efficiency.
Leave enough space between your refrigerator and the wall behind,
as well as space to either side, so air can circulate around the condenser
coils. Trapped heat increases energy consumption.
~
Check the door gasket occasionally to be sure the seal isn't broken by
debris or caked on food. Test by closing the door over a dollar bill so
that it's half in and half outside of the refrigerator. If you can pull
the bill out easily, the latch may need adjusting or the seal may need
replacing.
~ Avoid
frost build-up in the freezer compartment. Frost build-up should be less
than 1/4 inch in thickness. Excess frost build-up reduces the energy efficiency
of the unit.
~
Be sure the refrigerator isn't
located next to heat sources such as heat vents, stove or dishwasher.
Even direct sun will lower efficiency - block it if possible.
~ Check
temperature settings. Recommended temperatures are 37 - 40 degrees for
the fresh food compartment and 5 degrees for the freezer compartment.
Stand-alone freezers for long-term storage should be kept at 0 degrees.
To check the refrigerator temperature, place an appliance thermometer
in a glass of water in the center of the refrigerator and check the reading
after 24 hours. To test the freezer temperature, place thermometer between
frozen packages and check the reading after 24 hours.
~
A new, more efficient refrigerator can typically save you $70–80 per year
and will pay for itself in about nine years. Older models commonly use
an annual average of over 1,700 kWh, while equivalent models now use fewer
than 700 kWh. This can reduce your carbon-dioxide emissions by over 1,000
pounds a year.
The refrigerator is the single biggest power consumer in most households.

Appliances, which has more information on refrigerator care.
Remember to Recycle
Find out what your local recycling center accepts, and get in the habit of recycling these materials. You can reduce your household waste stream between 20 - 40%, as well as reducing the energy and pollution costs associated with manufacturing more materials.
The energy you save by recycling 1 glass bottle can light a 100-watt light bulb for 4 hours.
Five 2-liter recycled plastic (PET) soda bottles can provide enough fiberfill for a ski jacket.
Recycling 1 aluminum can can save enough energy to operate a TV or computer for 3 hours. Aluminum can be recycled using less than 5 percent of the energy used to make the original product. In other words, you can make 20 cans out of recycled material with the same amount of energy it takes to make one new one. In the US alone, the amount of aluminum thrown away is enough to rebuild the entire commercial airfleet every three months!
