Energy Saving TipsEnergy Tips
- Unplug electronics when not in use, or use a smart power strip to eliminate any "standby" power that devices consume.
- Look for ENERGY STAR label when shopping for electronics and appliances.
- Use a watt-meter to determine how much energy your devices are using.
- Do not line oven racks with foil. It blocks heat flow.
- Use a kettle rather than a pot to boil water. If using a pot, keep the lid on.
- Allow frozen foods to thaw completely before cooking.
- Use the air-drying option instead of heat drying. You can also turn off the drying cycle, open the dishwasher, and let the contents air dry.
- When buying a dishwasher, receive a home energy audit through Mass Save to be eligible for rebates for ENERGY STAR models.
- Scrape dishes instead of rinsing them prior to loading. Use a sink or pot filled with cold water, rather than hot running water.
- Be sure that the dishwasher is full, but not overloaded.
- Keep all drains and filters clean.
- Set your thermostat to 68°F when you are home, and 56°F when you leave. Each degree above 68°F can use 3% more energy!
- Install clock thermostats to automatically control heating and cooling.
- Have your heating equipment checked by a service professional.
- Clean or replace furnace filters periodically and have your furnace burner checked and cleaned annually.
- Dust or vacuum radiator surfaces and vents frequently and keep them unobstructed.
- Close fireplace dampers when not in use to keep heated or cooled air from escaping the chimney.
- Keep insulated drapes or shades closed in summer and open on sunny winter days. Close curtains or drapes on winter nights to reduce heat loss.
- If you use electric heat, consider replacing it with a high-efficiency, ductless heat pump system. The system can cut electricity use by as much as 50%.
- Check for drafts around windows and doors. Caulk and weather-strip where necessary.
- Install wall-outlet and switch-plate gaskets to reduce the flow of cold air.
- Install storm windows, or purchase window insulator kits to reduce drafts.
- Install storm doors to reduce heat transfer to the outside.
- Check your home's insulation, and sign up for an energy audit to have a professional inspect your walls, attic, and basement.
- Insulate hot water pipes.
- Replace all of your incandescent bulbs with LED ones. Sign up for a home energy visit to get them for no cost.
- Turn off lights whenever you leave a room or do not need them.
- When you are away from home, use a timer to turn lights on and off automatically.
- Use task lighting over desks, tables, and workbenches.
- Take advantage of natural light whenever possible.
- Use LEDs in holiday lighting displays. They use 90% less power than incandescent bulbs.
- Keep your refrigerator temperature setting around 38°-40°F, and the freezer around 5°F.
- Leave several inches of space behind and on the sides of the your refrigerator so air can circulate around the unit.
- Check for air leaks by shutting a piece of paper in the refrigerator door. If you can remove the paper without resistance, cold air may be escaping.
- Clean the condenser coils located underneath or in the back of your refrigerator or freezer periodically.
- Let hot foods cool before placing them in the refrigerator, except for cooked meat.
- Do not open the refrigerator door unnecessarily, or keep it open for prolonged periods.
- For older refrigerators, remove frost periodically.
- Wash clothes in cold or warm water rather than hot, and rinse in cold water.
- Fill your washer and dryer to capacity whenever possible. Wash smaller loads using lower water levels.
- Hang your clothes to dry whenever possible.
- Set your hot water heater at 120°F rather than 140°F.
- Replace washers on leaky faucets. Dripping can add up to wasted gallons each month.
- Turn off the tap when you shave or brush your teeth.
- Install low-flow showerheads and sink aerators. Sign up for an energy audit to receive them for no cost!
