- Use plants that require less water
- Get an Energy Star labeled electric devices
- Take shorter showers – Five minutes or less is best
- Turn off the water while soaping hands, shaving & brushing teeth
- Turn off sink faucet while scrubbing dishes & pots
- Install new toilets that use less than 1.6 gallons per flush
- Use a broom not a hose to clean driveways & walkways
- Place a bucket in the shower to catch excess water and use this to water plants.
- Insulate your water pipes. You'll get hot water faster and avoid wasting water while it heats up.
- Never pour water down the drain when there may be another use for it such as watering a plant or garden, or for cleaning.
- Verify that your home is leak free. Many homes have hidden water leaks. Read your water meter before and after a two-hour period when no water is being used. If the meter does not read exactly the same, there is a leak.
- Repair dripping faucets by replacing washers. If your faucet is dripping at a rate of one drop per second, you can expect to waste 2,700 gallons per year. This adds to the cost of water and sewer utilities, or can strain your septic system.
- Check for toilet tank leaks by adding food coloring to the tank. If the toilet is leaking, color will appear in the toilet bowl within 30 minutes. Check the toilet for worn out, corroded or bent parts. Most replacement parts are inexpensive, readily available and easily installed. (Flush as soon as test is done, since food coloring may stain tank.)
- If the toilet handles frequently sticks in the flush position letting water run constantly, replace or adjust it.
- Place a bucket in the shower to catch excess water and use this to water plants. The same technique can be used when washing dishes or vegetables in the sink.
- In the shower, turn water on to get wet; turn off to lather up; then turn back on to rinse off. Repeat when washing your hair.
- Install a toilet dam or displacement device such as a bag or bottle to cut down on the amount of water needed for each flush. Be sure installation does not interfere with the operating parts.
- Insulate your water pipes. You'll get hot water faster and avoid wasting water while it heats up.
- Store drinking water in the refrigerator. Don't let the tap run while you are waiting for cool water to flow.
- Do not use running water to thaw meat or other frozen foods. Defrost food overnight in the refrigerator or use the defrost setting on your microwave.
- Kitchen sink disposals require lots of water to operate properly. Start a compost pile as an alternate method of disposing of food waste instead of using a garbage disposal. Garbage disposals also can add 50 percent to the volume of solids in a septic tank, which can lead to malfunctions and maintenance problems.
- Consider installing an instant water heater on your kitchen sink so you don't have to let the water run while it heats up. This will reduce water heating costs for your household.
- When washing dishes by hand, fill one sink or basin with soapy water. Quickly rinse under a slow-moving stream from the faucet.
- Never install a water-to-air heat pump or air-conditioning system. Newer air-to-air models are just as efficient and do not waste water.
- Don't let water run while shaving or washing your face. Brush your teeth first while waiting for water to get hot, then wash or shave after filling the basin.
- Install water softening systems only when necessary. Save water and salt by running the minimum amount of regenerations necessary to maintain water softness. Turn softeners off while on vacation.
- If you have a well at home, check your pump periodically. Listen to hear if the pump kicks on and off while water is not being used. If it does, you have a leak.
- Avoid flushing the toilet unnecessarily. Dispose of tissues, insects and other similar waste in the trash rather than the toilet.
- Electric lighting adds heat to a space that must be removed in the summer by air conditioning. Turn lights off when not in use.
- Close the fireplace damper tight when the heating season is over.
- Wash full loads when using the washing machine or clothes dryer.
- A 40 watt incandescent lamp and a 40 fluorescent bulb use the same amount of electricity, but the fluorescent lamp creates five times as much light.
- Use the economizer cycle on the dishwasher and let the dishes drip dry instead of using electric heat to dry them.
- Don't block the supply air or return air ducts to the air conditioning system with furniture or drapes.
- Keep doors open in all rooms cooled by a central air conditioning system so that supply air can return easily to the unit.
- Be sure the air conditioning system is fully charged with freon so it will operate most efficiently when you need it.
- Check your auto and home air conditioning systems for freon leaks and repair them properly. Freon damages the ozone layer.
- When the weather is nice outside leave the AC off and open the windows.
- Duct air to ice machine condenser instead of using conditioned air that is exhausted to the outside. That way the heat generated by the condenser never enters the air conditioned space.
- Shop around for energy efficient computers, monitors and accessories.
- Use the kitchen exhaust fan when cooking to vent humid and odorous air.
- Be sure to open the windows now and again to air out the house or business. Fresh air is vital to human activity.

- Install an insulating blanket on the water heater so that it will operate more efficiently and cost you less each month.
- Using less hot water around the house saves energy too. Launder clothes in cold or warm water, take a shower instead of a bath or install a flow restrictor on the kitchen or utility room sink.
- Install a timer on the hot water heater and turn it on only for a couple of hours each day when all the domestic chores are done.
- Drying clothes on a line instead of in a dryer uses less energy and is easier on the fabric too.
- The coils at the back of the refrigerator are heat exchange surfaces. Keep them clean and the unit will operate at peak efficiency.
- Standing with the refrigerator door open lets humid air in. This makes it harder to cool and it will condense in the freezer into ice.

- Clean out the drain pan of the air conditioning unit regularly to prevent bacterial growth from spawning there, then entering the air.
- Common office equipment can be responsible for the release of volatile organic compounds, such as blueprint machines, copiers and white out fluids.
- If air is moving well, such as from a ceiling fan, it can be a little warmer and still give the sensation of being comfortably cool.
- Many ceiling fans can be operated in reverse in the winter to push warm air down from the ceiling to the occupied spaces.
- Store cleaning materials in tightly closed containers so fumes cannot leak into the air.
- The presence of respirable particles can affect the health and productivity of building occupants.
- Too much light on the desk surface can be just as harmful to the eyes as too little. Most offices are overlit, especially if the overhead lighting is supplemented by daylighting from windows.

- Homes and businesses can lower the temperature of domestic hot water in the summer months and still provide adequate comfort and service.
- A programmable thermostat at home can turn the central unit up a few degrees after you go to sleep in the summer and during the day, for 105. A gas powered furnace or hot water heater located in the home must have adequate ventilation so the equipment has enough combustion air to perform at peak efficiency.
