GE: Smart grid yields net-zero energy home
NISKAYUNA, N.Y.--General Electric unveiled a project at its research labs that will let homeowners cut annual energy consumption to zero by 2015.
These "net-zero energy homes" will combine on-site power generation through solar panels or wind turbines with energy-efficient appliances and on-site storage. Consumers will get detailed energy data and potentially control appliances with Home Energy Manager, a device that is expected to cost between $200 and $250, according to GE executives at a smart grid media day.
GE is piloting the in-home products this year and expects to have the appliances and energy display available next year. The premium for the more efficient, networked appliances will be about $10 more, GE executives said. A net-zero energy home would cost about 10 percent more by 2015, executives said.

When utilities have variable, or time-of-use, pricing, consumers could cut electricity use by 15 percent at on-peak times, typically in the morning and early evening.
GE appliances have been converted to have electronic controls and will have a small module in the back that will allow it to communicate with a home's smart meter. With that communication link in place, consumers can find out how much electricity individual appliances use and program them to take advantage of off-peak rates.
"I don't think any of us look forward to the day when we are monitoring hour to hour the cost of electricity. But I think all of us look forward to the day when we can set it and forget it," said Bob Gilligan, GE's vice president of transmission and distribution. "That's the future we look forward to."
For example, a consumer can set up the system so that the temperature in a water heater or thermostat can drop down to a certain level when nobody is at home.
Consumers can turn off features that will enable appliances to communicate with utilities to participate in utility-run demand-response programs, where a utility can adjust thermostats or appliances to shave peak-time consumption, according to Michael Beyerle, a marketing manager at GE's Consumer & Industrial appliance division.
Consumer incentive strong?
The idea behind the smart grid, which encompasses a range of technologies, is to make the electricity grid more efficient and reliable by applying information technologies and controls to the existing grid.
In addition to networked appliances, GE's Net Zero Home Project calls for on-site power generation through solar panels or wind turbines. GE produces solar panels and has invested in residential wind turbine maker Southwest Windpower. A 3,000-watt solar panel array, which costs roughly $30,000 to install, would be enough to supply all of a home's consumption, according to GE executives.

GE's Home Energy Manager control unit, which consumers access through a dedicated display, provides information to consumers but also is designed to optimize one-site energy generation and consumption.
For example, the control unit could evaluate electricity rates and see that running a dishwasher when the solar panels are producing is cheaper than running the load at off-peak times, explained Beyerle. Or a clothes drier can go into "conservation" mode during peak times where it will operate at a lower temperature and take longer to run.
During the media day, GE hosted a panel on challenges to the smart grid with Mark Brian, a consumer (and GE employee) using a suite of GE appliances at his home in Louisville, Ky.
He found that his monthly electricity consumption and his energy bills have gone down by 20 percent compared to last year. Because his home now has time-of-use pricing, his bills would have gone up if he hadn't been using the networked appliances. He added the system has given him ideas on how to take advantage of cheaper rates. "We still do the same stuff. We just do it at different times," Brian said.
GE executives said that the information-management tools need to be very easy to use. Also, policies need to be in place to address data privacy and to create financial incentives, namely variable pricing.
"There's a lot consumers are willing to do if they are properly informed and properly incented," said Gilligan.

Take $15,000 final cost for solar array into a 30 year mortgage @ 6%, that adds $90 / month onto your mortgage.
If by installing a solar array your electric bill was zero, then you'd net $15 ($105 - $90) a month.
It became an issue when the first commenter posted the asinine concept that government subsidies are "free."
And, no, you aren't gonna pay taxes either way. One way you're gonna pay taxes. The other way you're gonna pay a hell of a lot MORE taxes.
Try www.otherpower.com and you'll see what real people have had to deal with when it comes to using solar and wind energy.
Seriously though, why hasn't anyone bothered to explain how the planet was much warmer than it is today through most of its history and man obviously didn't cause that? What about the cool down that occurred 600 years ago? Who caused that?
it is exactly that kind of 'its not my problem' attitude that IS driving us to extinction, yes, extinction. I don't exactly believe in all this global warming **** either BUT I like clean air, I would like to live OFF the grid, and we are EVENTUALLY going to use all the coal, natural gas, and oil: then what? These technologies can equally be applied to live off the grid on your own power.
the "big brother" he is referring to is when you allow your appliances to be controlled by the power company via the network
b_bag... Failure to see the problem of increasing demand for finite & decreasing resources is shortsided and foolish. To consider this issue of secondary importance to 'economic collapse' is ludicrious since that's exactly what will begin to happen as we begin to exhaust our resources. 'Government Tyranny'? That's what you see when you read this?? Really??? I'd be curious what part of 'net-zero energy homes' translates into government tyranny. Maybe you're reading a different article... if so feel free to send it to me, as it sounds more interesting than this one.
"Been waiting for new technology for years, holding at 60 years"
Also some states, like West Virginia (with a large coal lobby) has no tax breaks or rebates for solar.
Figure $5 gas and convert to electricity and that will be the price. I found a conversion factor of 6 miles per kilowatt-hour. You can't do a btu conversion because gas is soooo inefficient . A car that gets 60 mpg will require an equivalent of 10 kilowatt-hours of electricity at an equivalent price of 50 cents a kilowatt.. Driving around for a day on 60 cents worth of electricity is not going to happen in the future, unless you generate the electricity. Of course you need to buy the equipment which will require a second mortgage.
And yes, the so called savings are really being borrowed or taxed from other people. Distortions of this sort don't give us accurate information about what makes economic sense.
When something costs a lot, that means there's a big impact in building. When the government hides the actual impact of things, we can't make good choices. But that is its modus operandi these days and the cause of our financial disasters.
more logical to reduce use by improving sytems in place ( ie hvac waste & antiquated lighting )
household energy waste in the usa is around 40% - total your gas/elect/water what is it $200 monthly
probably more - Be logical/practical even patriotic fix leaks & switch to Leds and you can stop wasting
$100s or $10,000s use the resources available to become less of a slave!
Would the GE controller only work on GE appliances? The problem now is agreeing upon a standard for communications or control, and I don't see much talk of that. Bluetooth solved the problem for cell phones and computer keyboard/mouse, though in an expensive way. It could be useful to just add a little connector to an appliance that allows a remote control to turn on/off or reduce power. Then you could add whatever control module works with your system and then just connect a short cable or plug. So far, Smart-Grid seems overly complicated.
While travelling in Argentina, I noticed the washing machine had a timer already built-in so you could run the wash overnight, just like the bread maker. It doesn't have to be that complex, but simple features like this need to be added.
By the way, b_baggins... a 3 degree rise in average global temps would be unprecedented, despite the propaganda you cling to. I guess if you're willing to inundate much of our coastline just so you don't have to shell out a few more bucks, you wouldn't mind moving yourself and your family there first. Bring your snorkel, simpleton.
If you feel more comfortable driving your gas-guzzling SUVs, and sucking your electric from smoke-belching coal plants - fine. Move to China, where that's almost a patriotic ideology. We're already paying through the nose for product of outdated and inefficient technology, and I'm sick of it. Time to move on and try to catch up to the 21st century. Will progress be more expensive? Name something worthwhile that isn't. YOUR taxes gone down yet?
/yeah GE selling EGRESS to the energy crisis for decades now. Old PT would be proud of their marketing.
So the $30,000 solar array will power all your energy needs? Including water heating and home heating/cooling?
or three more things; take one less auto trip each week - reduce your garbage output by 1 or 2 pounds daily-
BUY & use Led lighting (preferably made in the usa) There are dozens of logical and economical -
practical efficiency improvements that can be made by all of us

- And I can take this barnyard manure and put it through my composter to generate methane for the subdivisions gas turbine.

Showing 1 of 2 pages (47 Comments)I am now paying my electric provider in Houston, TX $3.50 a month for a smart meter that will not be installed for 5 years. How the Smart Meter is going to change my power usage in a 25 year old house currently escapes me. My bet is they will try and shaft the retail consumer more through hourly pricing which is why they are putting in the meters. But what is even stranger, the smart meters amount for Dallas is substantially less than for us in Houston. When asked our PUC could not explain. Surprise Surprise.
So in 10 years CNET why don't you drag out this puff piece and compare its statements to reality.
