Cut Your Energy Costs By Victoria Scanlan Stefanakos

Cut Heating and Cooling Costs

• Seal your house: Close the fireplace damper; install a timer (available at hardware stores) on the bathroom exhaust fan; seal ductwork.
• Cool your home naturally: Open windows on cool summer nights. Use energy-saving compact fluorescent bulbs (they emit less heat). Hang washing out to dry, and grill food outside. Install window awnings. Plant deciduous trees on the east and west to shade your house and cool it by as much as 20 degrees.
• Install an Energy Star–certified ceiling fan (50 percent more efficient than others) and comfortably keep your home four degrees warmer in the summer.
• Consider switching to a natural-gas water heater (which uses less than half the energy of an electric one), and turn the setting down to 120 degrees.

Potential savings: About $500 a year.

Green point: If one household in 10 bought Energy Star–rated heating and cooling equipment, the change in greenhouse-gas emissions would be equivalent to taking 1.5 million cars off the road.
