If you're investing in new computer equipment, look for Energy Star-rated computers, small servers, copiers, fax machines, and adapters. Energy Star estimates that using these rated electronics in your home office can save $115 over the products’ lifetimes.
Consider a laptop over a desktop. Laptops use one-third the power (22 watts) of a typical desktop (68 watts) when in active mode, according to ACEEE. Annually, a laptop could save you about $19 compared with a desktop.
Opt for a flat-panel vs. CRT monitor. A cathode-ray tube monitor consumes about 70 watts of power, while an LCD or flat-panel eats only 27, according to ACEEE data. Lower thermostats 10% during the day (to 62, for instance, from 68). This can save up to 10% on annual heating and cooling bills, according to the Use a space heater in winter and a portable or ceiling fan in summer. Both room-specific solutions cost far less than running whole-house systems at maximum capacity. Using fans or space heaters will eat into your savings for lowering the thermostat, but not nearly as much as using a central heating or cooling system throughout the house. Fans can run $25-$150; space heaters, $10-$80 at online retailers.
Keep heating and cooling costs at bay
