Home Energy Use

Updated on August 19, 2014

Your Electronics and Power Consumption

An increasing number and variety of home electronics have made their way into our homes. These great gadgets bring us previously unimagined efficiency, access to entertainment and information, increased security, greater connectivity to friends and loved ones, and numerous other advantages.

Unfortunately, these devices are also responsible for increasing home energy use. In fact, they are guilty of guzzling millions of kilowatts of energy each day. Reducing this energy consumption can reduce pollution and save individual consumers hundreds of dollars per year. Find out how to measure and reduce you home energy use on this page.

Measuring Power Consumption

What is Your Home Energy Use?

Everything from cable set top boxes and televisions to broadband modems and power adapters consume energy; even when devices are not in use.

Estimates vary, but some reports indicate that home electronics account for as much as 25% of all US residential home energy use.

Perhaps the first step in the process of dealing with the issue of electronics power consumption is to identify the items within your household that consume the most power. Reigning in the biggest offenders can make a significant difference.

Consumers can get a good estimate of the power consumption within their household by using standard calculations, making use of power meters, or taking advantage of some basic online tools.

How To Save Energy At Home

Tips to Curb the Apetite of Your Electronics

Eliminating all of the home electronics in your house probably isn't feasible or desirable, so what can you do to reduce your home energy use?

Here are a few tips:

Purchase electronics that consume less energy.

An LCD screen consumes less energy than a traditional CRT or a plasma screen. This is true for computers as well as televisions. Some DLP TV models that are laser based will reportedly be released in 2008; these sets will use 1/2 the power of a similarly sized LCD. (Note: see link below describing recent Panasonic developments that may put plasma on a more level ground with LCD in the near future and one on laser based DLP TV.)|

Look for the Energy Star label when making purchases.

Smaller means less power. A 32 inch television generally consumes less power than a 52" television.

Laptop computers use less power than desktop computers.Power off electronics when not in use and unplug if feasible; many electronics continue to use power when left plugged in.Obviously, users don't want to have to reprogram a device if it must have the time or other functions reprogrammed each time it's powered down, but in most instances, this is not a concern. Use of a power strip is a good idea, as several devices can be turned off at once by flipping a single swich and avoiding the need to dig around for the outlet. Use appropriate settings on display screens, especially the television.Avoid excessive brightness if the room lighting doesn't require it. YouTube has a demonstration by Philips of their simple settings adjustment here. If you plan on using a Test Pattern to help you here are some written instructions or without a test pattern try here.Make use of sleep mode, hibernate, or stand-by features when offered.Be sure to set such features to activate within 20 minutes so that the device reduces power consumption as appropriate. Again, it is still best to power off devices when not in use but stand by mode is a good safety measure for times when you might forget or plan to return within 15 or 20 minutes.

Reducing Power Consumption: The Future

Certainly, manufacturers are working to design home electronics that will consume less power and decrease the average home energy use.

Alternative power sources from hydrogen fuel cells, body heat, and solar power among others are being phased in as new technologies such as OLED for lighting and display screens on televisions and computer monitors are being refined for reliability, affordability, and energy conservation.

      Wow! I'm impressed, you've done your homework and put together some great tips.

      Another thing to consider is how you can share the energy/water you're saving with others in your community. District Energy Sharing solutions (low-temperature) are beginning to make their way into communities across the globe. The Whistler Athletes village (featured on the discovery channel recently), is a great example of just such an effort. It's not just about building up new communities with DES type systems, but more importantly retro-fitting existing communities with these capabilities. We need to urge our local municipal politicians to look into DES and other related technologies to help reduce community energy/water consumption.

      Seems like we have similiar goals, so I hope you'll consider stopping by to learn more about the E2O fifty community challenge to everyone from the grass roots to community officials and Government leaders to actively reduce energy and water consumption by over 50% within your communities.

      Please band with us and join the E2O fifty challenge, today.

      I need to get a new TV, especially one with a lower power consumption. I didn't even have that in mind when I purchased mine. It's one of those huge early HDTVs that weigh a couple hundred pounds. I can't wait to replace it. Lensrolling this to my home energy efficiency lens.

      Hi, very nice lens. I like the way you have taken electronic consumption and broken it out in many specific points. I'm totaly onboard with you on the standby power and put a lens on using a smart strip. The beauty is it does the thinking and you don't have the flip the switch - not always practical. I also have a lens on home energy saving tips if interested.

      How true! Plugged electronics do consume energy even when turned off. I hate pulling out the plugs so I use power strips with switches. A simple flip of a switch cuts off electricity flow. I also have a mini lens with more energy conservation tips. Please drop by when you have the time :)

      Research indicates that a leading cause for energy wastage is that people have little or no understanding of the amount they spend on electricity or gas while using domestic (electronic) appliances ! See the article

      It might be of interest to develop some free tools to stimulate this cost-awareness (and thus save a lot of energy!), i.e. this free software to monitor domestic energyconsumption and costs :

      Very nice lens, 5***** You can also wash your clothes in cold water - only really stubborn stains need hot water. That makes all the difference. I wonder too if it's better to wash and dry smaller loads. A drier works a lot better with a smaller load.

      I love my HEwasher and dryer. Also, I found a cool site that shows how you can save on your power bill each month just by turning things off (something we sometimes forget) -

      I even learned a thing or two. Slowly, I'm getting my plain light-bulbs switched over as the old ones burn out, but it's costing a lot of money initially to buy them.

      We made lowering our energy useage a family project. Lights are turned off. The 3 hour showers have stopped, we added insulation to the attic...

      Your lens has given me more ideas. Good job.
