At Home

Outside

  • Use a broom instead of a water hose to clean the sidewalk or driveway.
  • Plant shade trees and paint your house a light color if you live in a warm climate, or a dark color if you live in a cold climate.
  • Use a rake instead of an electric or gas leaf blower.

Heating and cooling

  • Clean or replace air filters as recommended. Energy is lost when air conditioners and hot-air furnaces have to work harder to draw air through dirty filters.
  • Adjust heating and cooling controls to reduce overheating or overcooling and use natural ventilation more effectively. During the summer, keep your thermostat at 74°F / 23°C. During the winter, keep it at or below 68°F / 20°C. Wear a sweater or long-sleeved shirt if you need extra warmth.
  • Install a programmable thermostat.This can reduce heating and cooling bills as much as 10% since you can conserve energy when you are away from home.
  • Set your clothes washer to use warm or cold-water setting, not hot.
  • Wrap your water heater in an insulating jacket.
  • Turn down your water heater thermostat. Thermostats are often set to 140°F / 60°C when 120°F / 49°C is usually fine.

In the kitchen

  • Do not overfill pans and kettles.
  • Use the correct size burner for your pan.
  • Keep refrigerators ice free.
  • Turn down your refrigerator temperature. Refrigerators account for about 20% of household electricity use. Use a thermometer to set your refrigerator temperature to 37°F / 2.7°C and your freezer as close to 3°F / -16°C or close as possible. Make sure that the energy saver switch is turned on.
  • Check the gaskets around your refrigerator/freezer doors to make sure they are clean and tightly sealed.
  • Run your dishwasher when it is full and use the energy-saving setting, if available, to allow the dishes to air dry. Not using heat in the drying cycle can save 20% of your dishwasher’s total electricity use.
  • Don’t let the faucet run while performing various activities such as rinsing dishes, or scrubbing vegetables.

In the Bathroom

  • Use less hot water by installing low-flow showerheads.
  • Take shorter showers.
  • Fix any faucets that drip.
  • Don’t let the faucet run while performing activities such as brushing your teeth or shaving.

Lighting options

  • Replace light bulbs with compact fluorescent lights. Efficient fluorescent light bulbs use less than half the energy than traditional incandescent bulbs do to produce the same amount of light, and they last a lot longer.
  • Turn off lights, TVs, and computers when they are not being used.
  • When purchasing an appliance such as a dishwasher or television, look for a model that’s highly efficient. If possible, choose an appliance that has an official label, such as the Energy Star in the US or A/A+ in Europe.

Intelligent insulation choices

  • Insulate your walls and ceilings. This can save 20 to 30% on home heating bills and reduce CO2 emissions. (If you have electric heat, you might also consider switching to more efficient gas or oil.)
  • If your home already has some insulation, consider increasing the amount in the attic and over the basement or crawlspace ceiling. The insulation in your attic should be at least 6 in thick, though a full foot is better.
  • If your home’s windows have only one pane of glass, they’re probably letting a lot of heat in (or out) of your home.Windows with two panes of glass—double-pane windows—are much better at insulating your house.
  • Install curtains on your windows.
  • Check for leaks and drafts around windows and doors, and add caulk or weather stripping as needed.

Do electronics use energy when they’re off?

The New York Times recently published an article asking how much electricity appliances use when they are turned off. This form of energy use is called, “standby power,” and it actually uses more energy than many think. The author turned to the Lawrence Berkeley National Laboratory and found that some devices can use as much as 20 watts of power when they’re off, but not unplugged. The Berkeley Laboratory also has interesting “home tours ” that show standby power usage in homes in various countries. Take a look at the power your electronics are using.
