You can take some steps to reduce the amount of energy that you are using and lower your utility bills:
Turn down your thermostat to 68 degrees. For every degree you lower your heat in the 60- degree to 70-degree range, you will save up to 5 percent on heating costs. Wear warm clothing like a sweater and set your thermostat to 68 degrees or lower during the day and evening, health permitting. Set the thermostat back to 68 degrees or off at night or when leaving home for an extended time, saving 5-20 percent of your heating costs (heat pumps should only be set back 2 degrees to prevent unneeded use of backup strip heating).
Replace or clean furnace filters as recommended. Dirty filters restrict airflow and increase energy use. Now is also the time for a furnace “tune-up.” Keeping your furnace clean, lubricated and properly adjusted will reduce energy use, saving up to 5 percent of heating costs. Reduce hot water temperature. Set your water heater to the “normal” setting or 120-degrees Fahrenheit, unless the owner’s manual for your dishwasher requires a higher setting. Savings are 7-11 percent of water heating costs.
Seal up the leaks. Caulk leaks around windows and doors. Look for places where you have pipes, vents or electrical conduits that go through the wall, ceiling or floor. Check the bathroom, underneath the kitchen sink, pipes inside a closet, etc. If you find a gap at the point where the pipe or vents goes through the wall, seal it up. Caulk works best on small gaps. Your hardware store should have products to close the larger gaps. Consider replacing your old gas appliances with an ENERGY STAR® water heater or furnace. Also contact your natural gas utility or visit their website for additional ideas, rebates and incentives.
Do not resort to using a BBQ or camp stove for indoor heat. Such equipment is designed to be used only outdoors and present significant safety hazards when used in any enclosed or partially enclosed setting. Besides the obvious fire hazard, they can produce high levels of carbon monoxide (CO). Remember that you cannot smell or see CO.
Cutting back unnecessary energy use is an easy way to keep your hard earned money in your pocket. Here are some suggestions you can do at home, at absolutely no cost to you.
Let the sunshine in. Open drapes and let the sun heat your home for free (get them closed again at sundown so they help insulate).
Rearrange your rooms. Move your furniture around so you are sitting near interior walls – exterior walls and older windows are likely to be drafty. Don’t sit in the draft.
Keep it shut. Traditional fireplaces are an energy loser – it’s best not to use them because they pull heated air out of the house and up the chimney. When not in use, make absolutely sure the damper is closed. Before closing the damper, make sure that you don’t have any smoldering embers. If you decide not to use a fireplace, then block off the chimney with a piece of rigid insulation from the hardware store that fits snugly into the space (dampers don’t shut fully without some leaking).
Eliminate wasted energy. Turn off lights in unoccupied rooms. Unplug that spare refrigerator in the garage if you don’t truly need it – this seemingly convenient way to keep extra drinks cold adds 10-25 percent to your electric bill. Turn off kitchen and bath-ventilating fans after they’ve done their job – these fans can blow out a house-full of heated air if inadvertently left on. Keep your fireplace damper closed unless a fire is burning to prevent up to 8 percent of your furnaceheated air from going up the chimney.
Use appliances efficiently. Do only full loads when using your dishwasher and clothes washer. Use the cold water setting on your clothes washer when you can. Using cold water reduces your washer’s energy use by 75 percent. Be sure to clean your clothes dryer’s lint trap after each use. Use the moisture-sensing automatic drying setting on your dryer if you have one.
Put your computer and monitor to sleep. Most computers come with the power management features turned off. On computers using Windows, open your power management software and set it so your computer goes to sleep if you’re away from your machine for 5 to 15 minutes. Those who use Macintosh computers look for the setting in your Control Panels called “Energy Saver” and set it accordingly. When you’re done using your computer, turn it off (see next tip). Do not leave it in sleep mode overnight as it is still drawing a small amount of power.
Plug “leaking energy” in electronics. Many new TVs, VCRs, chargers, computer peripherals and other electronics use electricity even when they are switched “off.” Although these “standby losses” are only a few watts each, they add up to more than 50 watts in a typical home that is consumed all the time. If possible, unplug electronic devices and chargers that have a blockshaped transformer on the plug when they are not in use. For computer scanners, printers and other devices that are plugged into a power strip, simply switch off the power strip after shutting down your computer. The best way to minimize these losses of electricity is to purchase
ENERGY STAR® products.
Install low flow showerheads. If you do not already have them, low-flow showerheads and faucets can drastically cut your hot water expenses. Savings of 10-16 percent of water heating costs.
Wrap the hot water tank with jacket insulation. This is especially valuable for older water heaters with little internal insulation. Be sure to leave the air intake vent uncovered when insulating a gas water heater. Savings up to 10 percent on water heating costs.
Choose ENERGY STAR appliances and electronics. When buying new appliances, choose ENERGY STAR-certified models. For example, a new ENERGY STAR refrigerator uses about 20 percent less energy than a standard new refrigerator, and 46 percent less than one made in 1980. A new Energy Star® clothes washer uses nearly 50 percent less energy than a standard washer.
Install a programmable thermostat. If you have a heat pump, select a model designed for heat pumps. Set-back thermostats can save up to 15 percent on energy costs.
Increase ceiling insulation. If your ceiling is uninsulated or scantily insulated, consider increasing your insulation to up to R-38 to reduce heating costs by 5-25 percent.
Seal ducts. Leaking ductwork accounts for more than 25 top 30 percent of heating costs in an average California home. Consider hiring a contractor to test the tightness of your ducts and repair leaks and restrictions in your duct. Many utilities have programs to assist you. Check out the Flex Your Power Web site for rebate and consumer programs or contact or local utility.
High-efficiency windows. If you are planning to replace your windows, choosing ENERGY STAR windows can reduce your heating and cooling costs by up to 15 percent.
