Working from home is becoming increasingly popular, but office equipment can run up the electricity bills. Look for ENERGY STAR computers, copiers, printers and fax machines when purchasing new equipment. ENERGY STAR products use about half the electricity of standard equipment. Turn off machines when not in use and make sure power management features are activated. Consider buying a laptop for your next computer upgrade; they use much less energy than desktop computers.
