Many people work from home at least one day per week. Working from home saves energy and time by cutting out the commute, but it may increase your home energy bills unless you use energy-saving office equipment.
ENERGY STAR-labeled office equipment is widely available. It can provide dramatic energy savings—as much as 75% savings for some products. Overall, ENERGY STAR-labeled office products use about half the electricity of standard equipment.
HOME OFFICE TIPS
- Selecting energy-efficient office equipment and turning off machines when they are not in use can result in significant energy savings.
- ENERGY STAR-labeled computers use 30%-65% less energy than computers without this designation, depending on usage.
- Spending a large portion of time in low-power mode not only saves energy but helps equipment run cooler and last longer.
- Putting your laptop AC adapter on a power strip that can be turned off (or will turn off automatically) can maximize savings; the transformer in the AC adapter draws power continuously, even when the laptop is not plugged into the adapter.
- Using the power management settings on computers and monitors can cause significant savings.
- It is a common misperception that screen savers reduce a monitor’s energy use. Use automatic switching to sleep mode or simply turn it off.
- Another misperception, carried over from the days of older mainframe computers, is that equipment lasts longer if it is never turned off.
Long-Term Savings Tip Consider buying a laptop for your next computer upgrade; laptops use much less energy than desktop computers.
HOME ELECTRONICS TIPS
- Look for energy-saving ENERGY STAR home electronics.
- Unplug appliances, or use a power strip and use the switch on the power strip to cut all power to the appliance, to avoid “vampire” loads. Many appliances continue to draw a small amount of power when they are switched off. These vampire loads occur in most appliances that use electricity, such as DVD players, TVs, stereos, computers, and kitchen appliances. Unplug battery chargers when the batteries are fully charged or the chargers are not in use.
- Use rechargeable batteries for products like cordless phones and digital cameras. Studies have shown they are more cost effective than disposable batteries. If you must use disposables, check with your trash removal company about safe disposal options.
