wk34_15_SaveEnergySaveMoney_header Why make your home more energy efficient?  Here are a few good reasons:
  • It saves money. It costs less to power a home that has been converted – in order 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.
  Find better ways to heat and cool your house. As much as half of the energy used in homes goes toward heating and cooling. The following are a few ways that energy bills can be reduced through adjustments to the heating and cooling systems:
  • 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 23 degrees to 21 degrees, 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 climates, can save up to $150 per year in energy costs.
  • At night, curtains drawn over windows, will better insulate the room.
  Replace incandescent lights. The average household dedicates 11% of its energy budget to lighting. Traditional incandescent lights convert approximately only 10% of the energy they consume into light, while the rest becomes heat. The use of new lighting technologies, such as light-emitting diodes (LEDs) and compact fluorescent lamps (CFLs), can reduce the energy use required by lighting by 50% to 75%. Advances in lighting controls offer further energy savings by reducing the amount of time that lights are on but not being used. Here are some facts about CFLs and LEDs:
  • 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.
  Seal and insulate your home. Sealing and insulating your home is one of the most cost-effective ways to make a home more comfortable and energy-efficient, and you can do it yourself. A tightly sealed home can improve comfort and indoor air quality while reducing utility bills. An InterNACHI energy auditor can assess  leakage in the building envelope and recommend fixes that will dramatically increase comfort and energy savings. The following are some common places where leakage may occur:
  • electrical receptacles/outlets;
  • mail slots;
  • around pipes and wires;
  • wall- or window-mounted air conditioners;
  • attics;
  • fireplace dampers;
  • inadequate weatherstripping around doors;
  • baseboards;
  • window/door frames;
  • switch plates.
  Install efficient showerheads and toilets. The following systems can be installed to conserve water usage in homes:
  • low-flow showerheads. They are available in different flow rates, and some have a pause button which shuts off the water while the bather lathers up;
  • low-flow toilets. 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;
  • vacuum-assist toilets. 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. 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%.
  Use appliances and electronics responsibly. Appliances and electronics account for about 20% of household energy bills in a typical home. The following are tips that will reduce the required energy of electronics and appliances:
  • 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. 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.
  • Did you know that 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.
  Cook smart. An enormous amount of energy is wasted while cooking. The following recommendations and statistics illustrate less wasteful ways of cooking:
  • 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/pots 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.
  Change the way you do laundry.
  • 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.
  • 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.
