New Technology Helps Save Energy at Home

As an SDG&E customer, you can now purchase and install home area network devices to see how much energy your home is using in near real-time and help identify high energy use appliances.

Want to know how much energy your home is using at any given moment? If you’re an SDG&E customer, you can now purchase and install displays called home area network devices to see how much energy your home is using in near real-time and help identify high energy use appliances. With an in-home energy display device that wirelessly connects to your SDG&E electric smart meter, you now have the opportunity to access a new tool that will help you make decisions to reduce your overall energy usage and costs.

With a few simple steps, you can find out approximately how much energy that refrigerator in your garage is using, as you watch the kilowatts and estimated cost per hour go up or down on a small digital display in your home when you turn appliances on or off. Gone are the days of needing to “guess-timate” how much energy an outdoor patio light is using during the evening compared to that new energy-efficient TV. With these new in-home displays, that information can be at your fingertips.

SDG&E has tested several new in-home energy display devices and you can learn how to connect these validated devices to your electric smart meters at sdge.com/han. The third-party in-home displays below range in price from approximately $60 to $120, and have been tested and validated for smart meter compatibility:

  • Energy Aware Technology PowerTab In-Home Display
    • Where to purchase: store.energy-aware.com
    • Features: Shows how much electricity your home is consuming at any given moment on a wireless and rechargeable, easy-to-use, magnetic backed display.

Jay, You are sure right about one thing, I guess it was about the 8th. or 9th. grade in elecrtic shop I learned that most thing's woule act as a condenser to some degree and the only way to dissapate the electrical energy was thru a SOLID grnd. And later when they brought computer controlled engines into the big trucks, Just what kind of havoc could be wrought by what looked like a solid ground that wasn't in fact one, They could drive you nut's if there was any resistance built up in the connection !

Ground loops .... when you have potential between "gounds" .. I deal with them in my camera systems with long runs or devices powered on different circuits ... to dissapate RF energy you have to have the correct wavelength antenna to match the frequency and some sort of RC network (resistor / capacitor) and a ground ... but that doesn't "clean" the area of RF energy .... just receives some and grounds it .. a pendant or something you stick on your cell phone is garbage ....

I have a few HAM radios VHF and HF and activity participate in Emgerency Communications. I take pride in being able to operate anyplace anywhere anytime needed in the country. That's a whole new subject we could talk about.
