- Federal, state, utility and local jurisdictions’ financial incentives, such as tax breaks, are very advantageous for homeowners in most parts of the U.S.
- It saves money. It costs less to power a home that has been converted to be more energy-efficient.
- It increases the comfort level indoors.
- It reduces our impact on climate change. Many scientists now believe that excessive energy consumption contributes significantly to global warming.
- It reduces pollution. Conventional power production introduces pollutants that find their way into the air, soil, and water supplies.
- Install a ceiling fan. Ceiling fans can be used in place of air conditioners, which require a large amount of energy.
- Periodically replace air filters in air conditioners and heaters.
- Set thermostats to an appropriate temperature. Specifically, they should be turned down at night and when no one is home. In most homes, about 2% of the heating bill will be saved for each degree that the thermostat is lowered for at least eight hours each day. Turning down the thermostat from 75° F to 70° F, for example, saves about 10% on heating costs.
- Install a programmable thermostat. A programmable thermostat saves money by allowing heating and cooling appliances to be automatically turned down during times that no one is home and at night. Programmable thermostats contain no mercury and, in some climate zones, can save up to $150 per year in energy costs.
- At night, curtains drawn over windows will better insulate the room.
- CFLs use 75% less energy and last about 10 times longer than traditional incandescent bulbs.
- LEDs last even longer than CFLs and consume less energy.
- LEDs have no moving parts and, unlike CFLs, they contain no mercury.
- electrical receptacles/outlets
- mail slots
- around pipes and wires
- wall- or window-mounted air conditioners
- attic hatches
- fireplace dampers
- inadequate weatherstripping around doors
- window frames
- switch plates
They are available in different flow rates, and some have a pause button which shuts off the water while the bather lathers up;
Toilets consume 30% to 40% of the total water used in homes, making them the biggest water users. Replacing an older 3.5-gallon toilet with a modern, low-flow 1.6-gallon toilet can reduce usage an average of 2 gallons-per-flush (GPF), saving 12,000 gallons of water per year. Low-flow toilets usually have “1.6 GPF” marked on the bowl behind the seat or inside the tank;
This type of toilet has a vacuum chamber that uses a siphon action to suck air from the trap beneath the bowl, allowing it to quickly fill with water to clear waste. Vacuum-assist toilets are relatively quiet; and
Dual-flush toilets have been used in Europe and Australia for years and are now gaining in popularity in the U.S. Dual-flush toilets let you choose between a 1-gallon (or less) flush for liquid waste, and a 1.6-gallon flush for solid waste. Dual-flush 1.6-GPF toilets reduce water consumption by an additional 30%.
- Refrigerators and freezers should not be located near the stove, dishwasher or heat vents, or exposed to direct sunlight. Exposure to warm areas will force them to use more energy to remain cool.
- Computers should be shut off when not in use. If unattended computers must be left on, their monitors should be shut off. According to some studies, computers account for approximately 3% of all energy consumption in the United States.
- Use efficient ENERGY STAR-rated appliances and electronics. These devices, approved by the U.S. Department of Energy and the Environmental Protection Agency’s ENERGY STAR Program, include TVs, home theater systems, DVD players, CD players, receivers, speakers, and more. According to the EPA, if just 10% of homes used energy-efficient appliances, it would reduce carbon emissions by the equivalent of 1.7 million acres of trees.
- Chargers, such as those used for laptops and cell phones, consume energy when they are plugged in. When they are not connected to electronics, chargers should be unplugged.
- Laptop computers consume considerably less electricity than desktop computers.
- skylights. It’s important that they be double-pane or they may not be cost-effective. Flashing skylights correctly is key to avoiding leaks
- Clerestory windows are short, wide windows set high on the wall. Protected from the summer sun by the roof overhang, they allow winter sun to shine through for natural lighting and warmth
- Seal all window edges and cracks with rope caulk. This is the cheapest and simplest option.
- Windows can be weatherstripped with a special lining that is inserted between the window and the frame. For doors, apply weatherstripping around the whole perimeter to ensure a tight seal when they’re closed. Install quality door sweeps on the bottom of the doors, if they aren’t already in place.
- Install storm windows at windows with only single panes. A removable glass frame can be installed over an existing window.
- If existing windows have rotted or damaged wood, cracked glass, missing putty, poorly fitting sashes, or locks that don’t work, they should be repaired or replaced.
- Convection ovens are more efficient that conventional ovens. They use fans to force hot air to circulate more evenly, thereby allowing food to be cooked at a lower temperature. Convection ovens use approximately 20% less electricity than conventional ovens.
- Microwave ovens consume approximately 80% less energy than conventional ovens.
- Pans should be placed on the matching size heating element or flame.
- Using lids on pots and pans will heat food more quickly than cooking in uncovered pots and pans.
- Pressure cookers reduce cooking time dramatically.
- When using conventional ovens, food should be placed on the top rack. The top rack is hotter and will cook food faster.
- Do not use the medium setting on your washer. Wait until you have a full load of clothes, as the medium setting saves less than half of the water and energy used for a full load.
- Avoid using high-temperature settings when clothes are not very soiled. Water that is 140° F uses far more energy than 103° F for the warm-water setting, but 140° F isn’t that much more effective for getting clothes clean.
- Clean the lint trap every time before you use the dryer. Not only is excess lint a fire hazard, but it will prolong the amount of time required for your clothes to dry.
- If possible, air-dry your clothes on lines and racks.
- Spin-dry or wring clothes out before putting them into a dryer.
