Book Lists Tips For Cutting Energy Use

Centuries of environmental neglect can’t be undone overnight. But you may sleep better knowing the task has begun under your own roof.

In his new book, “The Official Earth Day Guide to Planet Repair” (Island Press, $11.95), Seattle activist Denis Hayes offers these tips for cutting home energy costs and reducing greenhouse gas emissions:

Turn your water heater’s thermostat to the “warm” setting (120 degrees). Besides saving energy, you’ll avoid scalding your hands.

While you’re there, check to see if the water heater has an insulating blanket. (A blanket can pay for itself in less than a year.)

Use energy-saving settings on your refrigerator, dishwasher, washing machine and clothes dryer. Consider replacing an old refrigerator, which can use up to four times as much electricity as new models.

Use compact fluorescent lights where appropriate. They last longer than incandescent bulbs and use just one-fourth the energy.

Clean or replace filters in your furnace, air conditioner and heat-pump.

Rope-caulk leaky windows and other drafty seams.

Inspect attic insulation and add more if appropriate. (For recommended levels, visit www.energystar.gov on the Web or call (800) STAR-.)

Insulate hot-water pipes and ducts exposed to unheated areas.

Install a clock thermostat that allows you to adjust room temperature at night and when you’re away.

Cut air-conditioning costs by planting shade trees and shrubs on your home’s south and west sides.
