No Cost Options
- Start by setting your thermostat to 68°. Your heating system will operate less and use less energy. Turn your thermostat down 5° at night or when leaving your home for an hour or more to save up to $70 on energy costs each year. For a small investment, consider purchasing a programmable thermostat to adjust your home’s temperature settings automatically when you’re sleeping or away.
- Set your water heater to 120°. It’s simple. Your water heater won’t have to work so hard if it’s set at a lower temperature. The temperature control settings on water heaters either indicate “low, medium, and high” or actual temperature settings. Simply consider turning down your water heater to a slightly cooler setting to reduce the amount of energy used to heat the water while still keeping the water warm enough for home use. In fact, each time you lower the temperature by 10°F you’ll save 3–5% on your water heating costs. That’s a savings of $6-$10 a year. For a small investment (~ $20) consider adding a water heater blanket to your water heater tank to insulate the tank and reduce the amount of energy used to maintain warm water. Be sure to follow your manufacturer’s recommendations.
- In the winter, make the most of sunlight by opening window coverings on south-facing windows to warm your home. Also, consider closing window coverings in rooms that receive no direct sunlight to insulate from cold window drafts. At night, close window coverings to retain heat. Up to 15% of your heat can escape through unprotected windows, but the solar heat gain from the sun during the day can conserve valuable energy.
- If you have a clothes washing machine, use cold water. According to ENERGY STAR, washing clothes in cold water will save you about $40 a year with an electric water heater and about $30 a year with a gas water heater.
- Replace your furnace or heat pump filter regularly. Dirty filters reduce airflow, making your equipment work harder and use more energy. Replace your furnace filter monthly (unless it is a high efficiency filter designed to last several months) during the heating season to reduce heating costs by up to 5%.
Low Cost Options
- A more comprehensive tune-up of existing air conditioning and heat pumps has the potential to provide a significant opportunity for reducing peak demand and energy consumption. The common problems with installed systems include low airflow and incorrect charge, which both contribute to reduced operating efficiency. Studies have indicated that 60%-70% of installed residential air conditioning systems have improper refrigerant charge and/or inadequate air flow. The average energy savings potential from addressing improper refrigerant charge is 12%.
- Switch to compact fluorescent light (CFL) bulbs. They cost a little more, but you can save about $40 over the life of just one bulb.
- Weatherize your home and save up to 10% of your heating and cooling costs. A handy homeowner can seal up holes to the outside by weather-stripping doors and sealing windows and gaps along the home’s foundation.
- Insulate your home! The easiest and most cost-effective way to insulate your home is to add insulation in the attic. Other effective places to add insulation include unfinished basement walls and crawlspaces. Insulating walls can be more complex, so check with a contractor for advice. When insulation is correctly installed AND the home is totally weatherized, the average home can see a savings of up to 20% of your heating and cooling costs.
- Purchase ENERGY STAR® appliances. A smart choice. Appliances and electronics really contribute to your energy bill. When it is time to replace, remember items like refrigerators, washers, dryers, furnaces, TVs and computers have two price tags–purchase price and lifetime energy cost. According to ENERGY STAR, the average homeowner spends about $2,000 on energy bills every year. Change to appliances that have earned the ENERGY STAR rating, and you can save $75 a year in energy costs, while saving the environment.
