Intel showed off an experimental device last week in China that could someday substantially cut the costs of wiring homes and offices for energy efficiency, one more step in the company's foray into energy.

The device is a server/sensor that monitors the power consumption of the various appliances in a home or small commercial building in real time. The device then sends the data, via Wi-Fi, to a phone, PC or a home energy management console, like the one Intel showed off at CES earlier this year.

"Turn-on and turn-off signatures are like fingerprints," said Justin Rattner, Intel's chief technology officer in an interview. "Compressors, motors, TVs, stereos – all of them have a unique signature. It is relatively easy to train the system to recognize these things."

Intel’s new device can read your dryer’s mindIn the first stage, these devices will merely provide data to home energy consoles, but over time, remote control capabilities will be added so that lights can be turned off or thermostats turned down – either by a person or a computer – to save energy. Think of it as a Digital Mom ("Did you turn the lights off in your room...," etc.) without the guilt.

Intel will work with Flextronics to get the first commercially available versions out later this year.

Ideally, these sorts of devices and the pattern recognition software that powers them will curb the amount of hardware that will be required for home automation. Everyone loves the idea of home automation. The problem is the cost: outfitting lights and appliances with sensors and radios scares white-goods makers. With devices like this, manufacturers might be able to get away with inserting only basic computing functions into appliances and letting a central server conduct more of the computing tasks needed. In other words, forget intelligent appliances and say hello to the merely competent refrigerator.

A million homes or small office buildings rigged with automation equipment could curb the need to build a good number of 600 and 700 megawatt power plants, Rattner said.

"We believe that 30 percent of energy consumption is controlled by the consumer," he said, who will show off the device and conduct other demonstrations during a speech at the Intel Developer Forum in Beijing this week.

Part of Intel's interest in home automation stems from the lopsided nature of energy consumption when computing is compared with the rest of the world. Computers and IT equipment only account for two percent of the world's power consumption.

"If we were to hugely succeed and cut IT power in half, we'd only improve things by one percent," he said.

A bigger motive, however, lies in the opportunity to sell more chips. Intelligent appliances will need processors, boards and communications silicon. Last year, Intel began to vaguely discuss the opportunity in home automation (see the story we broke on the effort here) before coming out with its energy console and making it official.

Some of the technology behind these energy management applications to some degree can be traced back to sensor research Rattner and others showed off at IDFs in the early 2000s. (Here's a walk down memory sensor lane for you silicon fans.) With energy, remote sensors are finally finding a lucrative application to exploit.

Sensor servers and management consoles in some ways could also allow consumers and even utilities to postpone or downgrade smart meter rollout. Who needs a smart meter if your DSL router can already control your home? These devices, however, need data to work; hence, Intel is part of a coalition to get utilities to give third parties access to consumer energy consumption data.

Here's a laundry list of some of Intel's other energy efforts:

Intel may not ever produce solar cells itself, but expect it to try to get its technology for chips more integrated into solar.
