- Keep refrigerator ¾ full of food or water in bottles. A full fridge/freezer uses less energy to keep things cool.
- Plug appliances, chargers, printers, games, computer equipment, and all other electronics into power strips, and turn the power strips off when not in use.
- If you don’t have a power strip, unplug appliances when not in use. Even when turned off, appliances still consume a considerable amount of energy.
- Keep furniture away from air vents. Placing furniture over heating and cooling registers makes your heating systems and air conditioner work harder.
- Clean or change filters regularly. A dirty furnace or A/C filter will slow down air flow and use more energy.
- Cover air conditioner vents in winter. Sealing air leaks is the first and most important step to home comfort.
- Seal windows and door drafts. Excess air leakage can increase heating and cooling bills by 30%.
- Remember to turn lights off when you leave the room, and replace standard incandescent bulbs with CFL or LED bulbs – these newer bulbs last up to 10 and 25 times longer, respectively, and use about 1/4 of the electricity.
- Adjust your curtains and blinds to let sunlight in or out, depending on the desired room temperature and light.
- On cold days, turning down the heat to 55–65 degrees at night or when you aren’t home can make a big difference in your utility bill.
- Save 3% in energy costs for every degree you lower the thermostat setting in the winter.
- Use a programmable thermostat to heat/cool your home only when needed.
- Remember to turn down the heat at least 15 minutes before bedtime or when you leave your home for the day.
- On warm days, use a room fan instead of an air conditioner, or set the air conditioner to no lower than 75 degrees.
- Remember to turn your air conditioner off or to a higher temperature 15 minutes before leaving your home.
- Put lids on cooking pots and use heavy pans or iron skillets to retain heat.
- Once boiling or desired cooking temperature is reached, lower the heat.
- Don’t pre-heat oven; turn off the oven 5 minutes before item is cooked.
- Cook with small appliances, such as a crock pot, microwave, toaster, etc.
- Washing clothes in cold water prevents shrinkage and fading AND saves energy.
- Wash only full loads in your washing machine.
- Use the shortest cycle possible for washing clothes, and use the “water-saving” feature if your machine has one.
- A 5-minute-or-less shower is more energy efficient than taking a bath.
- Don’t let the water run while shaving or brushing teeth – instead partially fill sink while shaving. Rinse with short bursts of water for cleaning your brush and razors.
- When hand-washing dishes, never run water continuously. Wash dishes in a partially filled sink and then rinse them using the spray attachment on your tap.
