GE’s Plans to Help You Manage Your Energy Use

GE Appliances & Lighting created the Home Energy Management (HEM) business, intending to be the first major appliance company to provide a whole-home solution for energy management.

When synchronized with the local utility company’s home smart-meter, coming into popular use, the HEM acts as the “central nervous system” for monitoring resource usage and controlling energy consumption within the home. The HEM, with the ability to collect data on multiple appliances, provides both real-time and long-term trend information on power and resource consumption and solar generation to the homeowners.

GE’s new Home Energy Manager (HEM) monitors all networked appliances which can include the refrigerator, range, dishwasher, washer and dryer, water heater, and will track all other home energy consumption including microwaves and televisions.

One of the primary goals of U.S. smart grid initiatives is to better use the energy production capacity the country already has. Home energy consumption efficiency can increase significantly when homeowners the option to participate in time-of-use pricing programs, which reward homeowners for lowering their consumption during periods of peak energy demand (usually 2-7 PM).

Simply providing consumers with energy consumption information motivates energy savings. A U.S. Department of Energy study showed that providing real-time pricing information to consumers via a smart meter helped reduce electricity costs 10% on average and 15% during peak periods.

“Knowing what is consuming electricity, and how much electricity that appliances are consuming, can be very empowering,” states Dave McCalpin, general manager of the new HEM business. “People will be able to make smarter choices if they have information. The once-a-month electrical bill provides no insight into your usage habits. We intend to change that.”

HEM’s design is targeted to include:

* Demand Response Integration, supporting communication standards Zigbee SEP 1.0, to enable demand response communication between a utility’s home smart meter and appliances on the home network, enabling real-time load shedding of networked appliances;
* Five-Day Weather Forecasts on Internet-enabled installations (communications supporting Ethernet, Wifi, and Zigbee SEP 1.0 standards);
* Electricity Usage Data Monitoring for the whole home for both short and long terms;
* Power Sub Metering for each GE demand response-enabled appliance;
* Solar Generation Monitoring of inverter output, including short- and long-term data where available;
* Water Usage Monitoring via household-wide data monitoring at 1-gallon resolution;
* Smart Thermostat Interface with full-featured seven-day programmable communicating thermostats that accepts demand response temperature offsets.

Just How Much Energy is That Appliance Using?

My computer stays on through the week, only getting shut off on the weekend.  My answering machine and TV stay plugged in, their little red lights glowing in the night.  I do turn off the treadmill between uses and the DVD player too.

My energy habits are probably similar to many Americans.  If you’re wondering how much energy you’re wasting, or conversely, saving by turning appliances off, check out this energy calculator from GE:

This is a really cool tool that calculates  how much power each appliance consumes in watts or kilowatthours.  Alternatively, you can see how much each appliance costs to use in dollars, and how much it consumes in equivalent gallons of gas.

Some appliances are marked with a blue star indicating that an  EnergyStar model is available or click on the green star to see how much energy (and money) you’ll save with a new appliance.
