Seven easy ways to reduce home power consumption.

 

 

Drastic reductions in heating, cooling and electricity costs can be accomplished through simple changes, most of which homeowners can do themselves. Here are 7 easy ways to reduce the amount of energey your home uses.

1. 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:
    Periodically replace air filters in air conditioners and heaters. This increases the effeciantcy of your HVAC unit.
    Set thermostats to an appropriate temperature. Specifically, thermostats should be turned down at night and when no one is home. On average, In a decently insulated home, about 2% of the heating bill will be saved for each degree that the thermostat is lowered for at least 8 hours each day. So, turning down the thermostat from 75° F to 70° F, saves about 10% on heating costs.
Use a programmable thermostat. A programmable thermostat saves money by allowing heating and cooling appliances to be automatically adjusted 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.

2. Install a tankless water heater.

Tankless or instantaneous water heaters provide hot water only as it is needed. They don't keep water heated that is not being used by heating water directly without the use of a storage tank. When a hot water tap is turned on cold water travels through a pipe into the unit. A gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water.

3. Replace incandescent lights with LED.

In the past the average household dedicates 11% of its energy budget to lighting. Traditional incandescent lights loose 90% of their energy as 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.

4. 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 improves comfort and indoor air quality while reducing utility bills

Since hot air rises, air leaks are most likely to occur in the attic. Homeowners can perform a variety of repairs and maintenance to their attics that save them money on cooling and heating, such as:

    Plug the large holes. Locations in the attic where leakage is most likely to be the greatest are where walls meet the attic floor, behind and under attic knee walls, and in dropped-ceiling areas.
    Seal the small holes. You can easily do this by looking for areas where the insulation is darkened. Darkened insulation is a result of dusty interior air being filtered by insulation before leaking through small holes in the building envelope. In cold weather, you may see frosty areas in the insulation caused by warm, moist air condensing and then freezing as it hits the cold attic air. In warmer weather, you’ll find water staining in these same areas. Use expanding foam or caulk to seal the openings around plumbing vent pipes and electrical wires. Cover the areas with insulation after the caulk is dry.
    Seal up the attic access panel with weatherstripping. You can cut a piece of fiberglass or rigid foamboard insulation in the same size as the attic hatch and glue it to the back of the attic access panel. If you have pull-down attic stairs or an attic door, these should be sealed in a similar manner.
5. Install daylighting as an alternative to electrical lighting.

Daylighting is the practice of using natural light to illuminate the home's interior. It can be achieved using the following approaches:

    skylights. It’s important that they be double-pane or they may not be cost-effective. Flashing skylights correctly is key to avoiding leaks;
    light shelves. Light shelves are passive devices designed to bounce light deep into a building. They may be interior or exterior. Light shelves can introduce light into a space up to 2½ times the distance from the floor to the top of the window, and advanced light shelves may introduce four times that amount;
    clerestory windows.  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; and
    light tubes.  Light tubes use a special lens designed to amplify low-level light and reduce light intensity from the midday sun. Sunlight is channeled through a tube coated with a highly reflective material, and then enters the living space through a diffuser designed to distribute light evenly.

6. Insulate windows and doors.

About one-third of the home's total heat loss usually occurs through windows and doors. The following are ways to reduce energy lost through windows and doors:

    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.


7. 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. 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.
