Smart-grid spending to hit $200 billion by 2015

by Lance Whitney
  • 9 comments

Governments and utilities are expected to ramp up their investments in the electrical smart grid, spending a total of $200 billion worldwide from 2008 through 2015, says a new Pike Research report released Monday.

The term "smart grid" is shorthand for a number of technologies intended to automate and digitize management of electrical power. By computerizing the 20th century electrical system, utilities and others in the power industry hope to manage and control electrical output more efficiently and reliably. Though smart grid sounds like it's a single system, it's more an array of different tools and technologies, from smart meters to solar power, all designed to reduce costs, waste less energy, and provide better networking and communications between homes and utilities.

Technologies to automate the grid are expected to win around 84 percent of that $200 billion, says Pike. Smart metering systems to track and analyze the usage of electricity, gas, and water will grab 14 percent, while systems to provide juice to electrical cars will garner the remaining 2 percent.

"Smart meters are currently the highest-profile component of the Smart Grid, but they are really just the tip of the iceberg," said Pike managing director Clint Wheelock in a statement. "Our analysis shows that utilities will find the best return on investment, and therefore will devote the majority of their capital budgets, to grid infrastructure projects including transmission upgrades, substation automation, and distribution automation."

Though the grid has seen some technological advancements, it still suffers from a lack of intelligence and automation that would provide greater efficiency and cost savings, according to Pike. Four key goals will drive higher investments in the grid: improving reliability and security; improving operating efficiencies and costs; balancing power generation supply and demand; and reducing the overall electrical system's impact on climate change.

So far, development of the grid has been hurt not just by technical and financial limitations but also by a lack of vision and common standards, outdated regulations, and misunderstanding and even mistrust on the part of the industry over how the public consumes electricity, says Pike. As as result, government and industry bodies see the investment in the grid as a high priority.

As part of its push toward greener and more efficient technology, the U.S. government recently said it would spend about $3.4 billion of stimulus money on state-run smart-grid projects, with utilities kicking in another $4.7 billion. With such strong investment, Pike believes that industry revenues from the smart grid will likely reach their peak in 2013 and then taper off to become a smaller but still robust market over the foreseeable future.

Certified green home gets high-tech touches

by Martin LaMonica
  • 8 comments

NARRAGANSET, R.I.--Homeowner Kim Hageman wanted to "go green" at home without giving up any digital comforts.

Three weeks ago, the public relations and marketing executive, her husband, and their two children moved into a house built from the ground up to be both low energy and high tech. It is the first home to get the U.S. Green Building Council's LEED for Homes certification in the state of Rhode Island.

It's far more energy efficient than most because the building is tightly insulated and uses a ground-source heat pump, also called geothermal, for heating and cooling. The builders and homeowners followed a number of other environmentally sensitive guidelines to get the LEED certification, including using recycled materials from local sources and a large cistern for most outdoor watering. Through recycling, the entire construction project, which included tearing down an existing building, only sent one dumpster to the landfill.

The building is cutting edge when it comes to high tech, too. It has a home-automation system from Control4 to access movies and music from the TV and touch-screen displays around the house. That system also doubles as the energy management console, giving teh family a way to control temperature and lighting, as well as get real-time data on electricity use.

Since the family has just moved in, Hageman can't say yet whether the energy monitoring system has helped conserve electricity. But at the very least, Hageman knows how much she is spending on average per day. In theory, that information will allow the Hagemans to notice a high consumption rate and turn off unused electronics and lights.

Hageman said she decided to create an LEED-certified green home because she wanted to do something to help the environment and because she thought it would be good for her public relations and marketing business.

One of the biggest challenges of the entire 14-month project was finding qualified contractors versed in green-building design and products. Now, she hopes the house will serve as a resource for other homeowners looking to incorporate some of its features, such as using sustainably forested wood, water-efficient appliances, and a rainwater harvesting system.

The contractors followed the Consumer Electronics Association's guidelines for a "green" audiovisual installation, where wiring is minimized and the technology upgradeable. Hageman estimates that the system uses about half as much wiring as another comparably high-tech home.

The house still has a significant environmental footprint simply by its size--more than 4,500 square feet. But the Hagemans have made a number of energy efficient choices up front, such as using foam insulation throughout and EnergyStar-rated appliances. They are also considering a sizable solar electric array, which could make it a net zero energy home.

'Smart' device makers: Variable electricity rates needed

by Martin LaMonica
  • 15 comments

For grid-aware appliances to deliver on the promises of the smart grid, electricity rates needs to be overhauled, according to appliance makers.

The Association of Home Appliance Manufacturers (AHAM) on Monday released a white paper (click for PDF) outlining what it called the requirements for smart grid acceptance. The release of the paper was timed for the same week that international climate negotiations are going on in Copenhagen.

Smart grid technology, including so-called smart appliances, have the ability to help consumers cut their electricity use and shave their utility bills--but only if three pieces fall into place, according to AHAM. Those include time-of-use electricity rates, open communications standards, and products that let consumers retain full control of their home appliances.

Utilities around the world are installing two-way meters that can send information back and forth between customers and utilities. That data can be used in a number of ways, including real-time energy monitoring and dialing down electricity use at peak times.

But already there are complaints surfacing that consumers aren't getting the benefits of those more capable and more expensive smart meters.

AHAM says that time-of-use pricing is required to motivate consumers to run energy-intensive tasks, such as running a load of laundry or the dishwasher, at off-peak times. "It must be recognized that existing residential tariffs and rate structures do not provide sufficient economic incentive to spur maximum consumer participation in the use of smart grid technologies," the industry association said in its paper.

The reasoning behind time-of-use electricity pricing is to reflect cost of power to utilities, which varies depending on the time and demand.

GE, Whirlpool, and other appliance makers plan to make appliances that can receive signals from a smart meter on changing electricity prices. On a hot summer day when air conditioners are maxing out the grid's capacity, a dishwasher, for example, could go into energy-saving mode and take longer to finish its job. GE on Monday said it will introduce a line of "smart-grid enabled" washers and dryers in 2012.

However, many states charge for electricity at the same rate at all times, so consumers have little financial incentive to run loads at off-peak times or purchase appliances that can respond to demand response signals from smart meters.

In addition, AHAM calls for a "rapid drive towards open standards" for in-home communications. The National Institute for Standards and Technology (NIST) is overseeing an effort to codify a number of smart-grid related standards.

But in the area of home networks, disputes among appliance companies is slowing down the process, according to George Arnold, the national coordinator for smart-grid interoperability at NIST.

Finally, AHAM said that privacy and security need to be assured for consumer acceptance. "Projects should emphasize the consumer as the decision maker as opposed to scenarios where the utility possesses absolute control over the consumer's appliances and devices," it said.

SmartSynch offers universal router for smart grids

by Candace Lombardi
  • 5 comments

SmartSynch announced Wednesday night that it has a plan for allowing universal communications between appliances, smart grids, and utilities, regardless of which communication protocol is used.

In May 2008, the Jackson, Miss.-company garnered $20 million in a funding round led by Credit Suisse to develop its communications devices and software for smart meters.

What has emerged is the GridRouter, an Internet Protocol-based universal router with an open platform that can communicate with public and private networks whether they be using WiMax, municipal Wi-Fi, or a proprietary network system.

The GridRouter device could become a darling of utilities by enabling them to connect existing proprietary networks to the GridRouter without having to upgrade their entire system, and using existing off-the-self IT management tools to do it.

The company's public relations team has been telling the press that "SmartSynch sees this product doing for the smart grid what Cisco did for the Internet."

While such grid and appliance interoperability claims might only catch the eye of industry wonks, average consumers should also perk up their ears and listen. Progress on that front could mean the difference between paying a premium for a smart-grid-enabled appliance, or having it come standard on most mass-produced appliances within the next half-dozen years.

SmartSynch's upgradable GridRouter is built to allow utilities to add multiple communications technologies from difference companies and make them all interoperable.

Currently, companies and organizations are jockeying to back what they hope will be the standard of choice for smart-grid interaction when it comes to software and communications tools. The Wi-Fi Alliance announced in November, for instance, that it has a smart-grid task force reviewing how its standards might be modified to become the best choice for smart grids. Google's PowerMeter, while using its existing Web-based portal to provide a platform for smart-grid home data, has partnered with AlertMe, which uses ZigBee instead of Wi-Fi for home devices to communicate with a central hub and smart meter.

Appliance manufacturers like GE and Whirlpool have publicly expressed enthusiasm about incorporating smart technology into their products.

GE announced in July that it's testing Tendril as possible smart appliance software and started several pilot projects in places like Masdar City and Hawaii.

But there has also been some hesitation. Whirlpool said it would like to phase out all "dumb" appliances by 2015, but won't do so until a clear standard communications winner emerges.

Who could blame them? No one wants to be the one left with noncompliant technology once clear winners begin to emerge. But because of this, standardization squabbles could become a hold-up in the smart-grid evolution.

If SmartSynch's GridRouter can provide an easy an out-of-the-box solution to syncing everyone up, as the company claims, it could be the grease needed to quicken the smart-grid build-out.

Smart grid potential gated by broadband

by Martin LaMonica
  • 5 comments

CAMBRIDGE, Mass.--U.S. energy objectives are closely intertwined with--and in many cases, rely upon--the country's broadband infrastructure, government officials and smart-grid company executives say.

The Federal Communications Commission on Monday held a "field hearing" at the Massachusetts Institute of Technology on the role of communications in energy and environment. It was an information-gathering session designed to help set a national broadband strategy.

The entire notion of the smart grid supposes connectivity at different points along the grid. Adding digital technologies to the existing system will allow energy to be used more efficiently, increase reliability, and let grid operators use more solar and wind power, say smart-grid advocates.

During the hearing, speakers argued that broader broadband coverage lays the foundation for those benefits by enabling smart-grid applications, such as home energy monitoring, alerting utilities to outages, and charging plug-in vehicles economically and without stressing the grid.

U.S. Rep. Ed Markey (D-Mass.), who has been involved in both telecom deregulation and energy legislation, said here Monday that future economic growth is tied closely to the intersection of energy and broadband.

"The smart grid is an electricity Internet. Without the broadband revolution, you cannot have the revolution we're talking about," Markey said. "If you look at the energy sector and the broadband sector, you can determine the economic growth of that country."

In the case of consumers, smart-grid companies are already relying heavily on home broadband connections. Smart meters are equipped with networking gear so that data can regularly be sent back and forth between customers and utilities. Millions of smart meters will be installed in the next three years. But there will still be millions of homes without smart meters, and many utilities have limited meter communications for security reasons.

As a result, energy monitoring companies are designing products so that they can function with an Internet connection instead. Rather than have a smart meter provide real-time energy use to an energy display, for example, data can be collected using different workarounds, including Internet gateways that give consumers access to a Web portal.

Wider broadband coverage would open up energy-efficiency services delivered through home energy displays to a bigger set of people, said Adrian Tuck, CEO of Tendril, a company focused on smart energy monitoring.

"It's cheaper to give low-income families access to a broadband than it is to give them smart meters," he said. "We use the existing broadband to compensate for the fact that smart meters are not in place."

Regulatory 'hairball'
Better broadband coverage opens up the market to more businesses, too, said Rick Counihan, president of regulatory affairs at energy-efficiency company EnerNoc.

EnerNoc ratchets down electricity use in office and industrial buildings during peak times by connecting to its customers' meters. That communication with many smaller companies is done with a cellular modem, rather than an Internet connection, which makes the service more expensive, he said.

For utilities, connectivity is integral to improving the reliability of the grid, according to executives from utility companies who said that more radio spectrum would help ensure reliable communications to detect outages.

The other area that needs work on the government level is standards and interoperability. The National Institute of Standards and Technology is now leading an effort to establish the necessary standards for smart-grid, covering everything from cybersecurity to in-home communication protocols. But there would need to be coordination among various government agencies for new grid products to be plug and play.

Regulations need to be put in place to promote efficiency at utilities and to reflect peak-time and off-peak pricing of electricity, panelists said.

"The technology is there. The markets are there. The entrepreneurial drive is there," said venture investor Chuck McDermott of Rockport Capital. "The hairball occurs at the regulatory side. We don't have a system that accommodates a dynamic market."

Utility energy storage no longer just giant batteries

by Martin LaMonica
  • 13 comments

If you need more evidence that energy storage is much more than lithium ion batteries, take a look at the latest smart-grid utility storage projects.

The Department of Energy on Tuesday announced that $620 million in stimulus funding is going to 32 smart-grid programs, which will be coupled with another $1 billion in private money. A total of $770 million from government and industry sources in the next few years will go to energy storage, giving a number of storage technologies a dose of real-world experience. (See this PDF for details.)

Notable in the list is the prominence of compressed-air energy storage and flow batteries, two technologies rarely discussed just a few years ago. Also in the mix are flywheels and using batteries for distributed energy storage in communities.

It's unlikely that all the DOE-aided projects will immediately prove to be commercially viable. But storage has clearly emerged as a key component in the vision of the smart grid. A number of start-ups are developing technologies they hope can address a specific storage application or undercut pumped hydro, considered the cheapest form of utility storage, on price. With pumped hydro, water is pumped uphill and released at peak times to run a generator. But its use is limited by geography.

Many of the 16 Energy Department power storage grants were focused on storing wind power, which is a variable source of energy. In California, for example, utility Pacific Gas & Electric plans to store the power generated by wind turbines at night, when turbines are most productive in underground caverns. During the day, when grid demand is higher, the air is released and passed through a turbine to make electricity.

The advantage of underground compressed air storage is that it can be cheaper than batteries and can store many hours worth of energy. PG&E forecasts that its Kern County, Calif., project can deliver 300 megawatts of power for 10 hours, enough to supply tens of thousands of homes.

Another novel technique is using metal tanks to store compressed air, a technology being developed by a Dartmouth College spin-off SustainX. The compressed air is released to run a hydraulic motor that drives a generator to make electricity.

Flow batteries, meanwhile, use tanks of liquid electrolyte solutions. When the two liquids interact, there is a chemical reaction that creates a flow of electricity.

An advantage of this approach is that store large amounts of energy and discharge relatively quickly, according to the Electricity Storage Association. One project will use technology from Premium Power, which makes tractor trailer-size zinc flow batteries to maintain a steady frequency on the grid and supply power during times of peak demand.

Different strokes
The variety of technologies points to the range of energy storage applications. Flywheels from award winner Beacon Power, for example, can absorb and discharge megawatts' worth of power to the grid but only in 15-minute bursts. Still, flywheels are getting more attention because they are a nonpolluting replacement to the natural-gas plants now used to smooth out short-term fluctuations in grid frequency, according to the company.

Large batteries, too, will be further tested for grid storage. Duke Energy plans to use multiple battery types for 20 megawatts' worth of power delivery at the Notrees Windpower project in Texas. The "hybrid" battery system is being designed for two tasks: to smooth out short-term grid fluctuations and to supply hours' worth of power during the day, according to a Duke Energy representative.

Utility Portland General Electric in the next two years plans to install five batteries from auto battery supplier Ener1 to supply enough juice to power 400 homes for about an hour. Alternative chemistries, including lead carbon batteries from East Penn Manufacturing, will also be used.

One project will test the viability of used car batteries for grid storage. Lithium ion plug-in car batteries from A123 Systems will be used to supply 25 kilowatts for two hours in 20 community energy storage projects. The performance of lithium ion batteries degrades after many years in a car, but there is still sufficient storage and power for grid applications, utility executives say.

DOE smart-grid trials fund utility-scale energy storage

by Martin LaMonica
  • 5 comments

The Department of Energy on Tuesday awarded $620 million in smart grid projects, the second major wave of government-led funding to modernize the electricity grid.

The money will come from the stimulus package and be matched by commercial companies, making the total spending $1.6 billion spread across 32 demonstration projects in 21 states. A total of $8.1 billion in smart-grid spending from public and private sources was announced late last month.

Energy Secretary Steven Chu announced the awards at Ohio-based utility AEP, whose GridSmart program is considered one of the more technically advanced.

The bulk of the DOE awards--$435 million--will be aimed at adding communications to the transmission and distribution grid through the installation of two-way meters, sensors on the transmission lines, and in-home energy displays.

By networking devices along the grid and adding digital controls, utilities can more easily locate and fix outages and use their energy supply more efficiently. For consumers, in-home displays will allow them to get a real-time readout of their electricity usage to help ways to cut down consumption. Some utilities also offer programs where consumers can get cheaper rates to shave power use during peak times.

The rest of the DOE funding will go toward testing a range of energy storage technologies, including flow batteries, flywheels, and compressed air storage. With storage, utilities can more easily use solar and wind power by better managing the flow of energy on the grid.

Time short to agree on smart-grid standards

by Martin LaMonica
  • 9 comments

CAMBRIDGE, Mass.--The first crack at vital smart-grid technical standards are due next year and some companies are already gumming up the works by pushing their own networking technology, according to the government official shepherding the process.

The need to hammer out interoperability standards is urgent and the task is extremely complex, said George Arnold, the national coordinator for smart-grid interoperability at the National Institute of Standards and Technology (NIST) who gave a presentation at a seminar organized by the IEEE here on Saturday. There will eventually be hundreds of standards covering many areas, from cybersecurity to how meters talk to plug-in cars.

"We've never tried to anything of this magnitude before," Arnold said. "It's more complicated than the Internet and Internet standards have been evolving for over 20 years."

By contrast, smart-grid standards need to be agreed on quickly, with the next phase of a multiyear process due next to begin year. Technical interoperability through standards is supposed to safeguard various players, including consumers and utilities, against technical obsolescence and wasted investment. About $8.1 billion of federal, state, and industry money will be spent on upgrading the electricity grid in the next three years.

The smart grid touches a number of different devices in a home and on the electricity grid. There's a push to establish the technical blueprints and standards certification by late next year.

In the case of smart appliances, Arnold said he is ruffling feathers by pushing networking companies to sort out a dizzying number of options.

With two-way meters installed in people's homes, a meter can send a message that higher electricity prices have gone into effect. For example, during a hot summer day when the air conditioning load on the grid is high, utilities may look to "shed load" and have some of its customers volunteer to lower their consumption.

An appliance, such as a dishwasher or clothes dryer, equipped with a chip should be able to receive the message from the meter and go into energy-saving mode. A "smart" appliance could receive the message and perhaps do a job in an hour instead of half an hour to use less power. That handshake between the appliance and meter needs to be standardized to make sure that consumers can buy products from different suppliers.

The problem is that there are multiple methods for passing energy-related information around the home and the companies involved are pushing their own technology, creating a "mess," said Arnold. There are wireless protocols Zigbee and Wi-Fi and at least six powerline communication protocols that use a home's wiring to move data.

"We're trying to accelerate the normal process and gravitate to a few market solutions, which normally takes years," he said after his talk. "Proponents of various communications standards all have a role but at the end of the day, there has to be some assurances for consumers."

Whirlpool last month announced that it would make 1 million "smart energy" clothes dryers by the end of 2011. That commitment, however, was contingent on standards being cooked by the end of 2010 and changes to regulations to reward consumers, appliances makers, and utilities to shave peak-time electricity use.

General Electric's appliance division, too, is making a complete line of demand response appliances.

But appliance manufacturers will be reluctant to support multiple protocols in their networking chips because that could raise the price of these grid-aware white goods.

Internet as a model
The situation with home-area networking is just one instance playing out among the dozens of technology providers, utilities, regulators, and standards bodies. Conflict over standards is common in the tech industry because betting on a failed standard can be costly. But the situation is more complex in the smart grid given the number of groups with a stake in the process.

NIST was given authority over smart-grid standards in 2007 and in September released a framework and roadmap for interoperability. (Click for PDF.) Arnold said that there has been strong industry support for the effort. But given that a number of smart-grid trials are already under way, NIST is focusing on accelerating the process, which will result in a testing and certification next year.

In some ways, NIST is looking at the Internet standards as a model for how the process should be operated. Last week, there was an event called Grid-Interop where a governing panel was created specifically to focus on interoperability.

"Over time this organization (called the Smart Grid Interoperability Panel) is going to become something like the Internet architecture board," said Arnold. "It's not being set up to develop standards. It's really being set up to develop the overall architecture and select which standards should be used."

Internet pioneer Vint Cerf is on the governing board of the panel, he added.

In its framework document, NIST identified eight priority areas where there is a lack of standards, which includes networking communications, security, and plug-in vehicles. But it is relying heavily on existing standards, including international standards, wherever it can to expedite the process, Arnold said.

That means coordinating among several standards organizations because the smart grid touches so many pieces of hardware and software. For example, to standardize plug-in electric vehicles requires coordination among upwards of 10 different organizations to cover national electric safety codes and standards for car batteries, networking, energy storage, and smart meters.

One of the principles that NIST is pursuing is that standards-based products should be backward-compatible since standards will continue to evolve for many years, Arnold said. He added that communications protocols over time should be based on the Internet Protocol.

Will consumers plug into home energy displays?

by Martin LaMonica
  • 29 comments

Dozens of home energy monitors are coming to market, but nobody knows whether only hybrid Prius owners will use them.

Whole home energy monitors, or displays, are designed to help consumers conserve energy by providing far more detailed information than a monthly bill. These types of devices are already available, but millions more are poised to enter U.S. homes in the next two years, largely through utility-run smart grid programs.

The gadgets themselves vary, but the common thread among them is the ability to capture a stream of energy information from a meter at a given moment. Simply by surfacing real-time data, either with a small device or Web software, it's believed the system will prompt people to change their habits and ratchet down consumption by 5 percent to 15 percent, according to studies (PDF).

But even as more sophisticated and user-friendly products come to market, it's unclear whether consumers will track energy use regularly, particularly once the novelty wears off.

"Not everybody is an energy nerd yet," said David Schatsky, principal at consulting company GreenResearch. "While people who study this area are aware of the energy space, the average consumer is not."

Schatsky recently completed a study on home energy displays and concluded that they won't likely be a hot holiday season gift anytime soon. In the next two to three years, he projects there will be millions of these devices installed, with the numbers ramping up to tens of millions after that. Existing displays cost roughly $100 to $200 but Schatsky expects that many consumers will initially receive them for free from utilities as part of smart-grid programs.

In a survey, he found that about half of consumers said they were interested in tools to lower home energy bills. But in reality, the percentage of people who will actively manage their energy is probably much less. There are also technical hurdles to making these devices provide real-time information and useful recommendations.

As a result, he expects that energy-efficiency programs run by utilities in the next few years will drive adoption and provide some lessons on what resonates with consumers and not. As part of the multibillion dollar smart-grid grant program announced last month, about one million consumers will get in-home displays from utilities looking to lower consumers' energy consumption in smart-grid programs. Those programs are expected to get off the ground in the next few months.

Motivating consumers
The drive behind smart-grid technologies is to enable the grid to use electricity more efficiently, integrate more solar and wind power, and potentially eliminate the need to build new power plants to meet growing demand.

Countries around the world are investing to upgrade their grids, but there's a gnawing concern in the U.S. that consumers aren't sold on the benefits. Home energy displays are supposed to be one of the ways that utilities can help consumers save money and lighten their environment footprint.

At their most simple, a whole-house energy monitor shows what's happening on an electricity meter and translates that into cost and kilowatt-hours. For example, seeing that a home's current electricity use is higher than typical could lead a person to unplug a video game console or turn off lights. More sophisticated devices can provide information on how much individual appliances use and generate statistics.

When used as part of smart meter rollout, these devices can be a gateway for energy-efficiency services offered by a utility, such as demand response. For instance, a monitor can employ a color system where red indicates that the electricity rate has gone up because it's a time of peak demand.

The Web is a natural extension to these energy gadgets. Google's PowerMeter is being offered through utilities that install smart meters, which feed real-time energy use to the Web-based monitoring application. But Google is starting to offer PowerMeter through other devices, including a small monitor called the TED 5000.

The information and displays are meant to not only inform consumers but to motivate them to be more efficient. In order for that to work, the devices need to be simple to install and useful just at a glance, say monitor makers.

"There's all this talk about the smart grid, but if customers don't participate, it will be a bust," said Paul Nagel, the vice president of strategic development at home automation start-up Control4. "If they don't engage, then they'll never get energy savings."

Home area networks
One of the challenges that all energy display companies face is the technical barriers to getting them installed. The most sophisticated system would use a home-area network built around a smart meter and a network of Zigbee-enabled appliances and thermostat. But even with big investments in the smart grid, millions of homes still won't have smart meters.

Energy management companies are developing alternatives for getting data regularly from the meter to a display. Bridge devices can read meter information using the automatic meter reading (AMR) protocol, which is already available in millions of meters. Another approach is to clamp sensors onto a circuit box to get data or to install "smart plugs," which transmit data from appliances.

Even if a consumer is willing to navigate these technical issues, there is the question of whether the device will provide energy savings over time.

New home energy management companies are focusing on doing more than just monitor data because they are worried about what's called "mean time to kitchen drawer." That is, a person may have a small display on a kitchen counter as a reminder about energy use. But when the batteries run out, will they simply stash it in a kitchen drawer and forget about it?

Companies are now building in data analytics to provide recommendations or to automatically control appliances to ratchet down energy use. EcoFactor, for example, is developing a hosted software application that can analyze data from wireless thermostats and make changes to make the home more efficient.

Control4, a company which does touch-screen displays to manage video and music in a home, is now branching into energy management. Its EMS 100 device, which runs Linux on an Arm 9 processor, is powerful enough to analyze daily information to provide recommendations on how consumers can make changes to save energy, said Nagel. The company plans to offer it through utilities starting in the first quarter of next year.

Energy management services could be bundled with other home-automation products or even cable and telecom services. iControl and AlertMe in the U.K. plan to bundle security services with tools to manage heating, cooling, and lighting.

One way that utilities and energy management companies expect to motivate consumers is by comparing one home's usage to neighbors in comparably sized homes. Start-up Grounded Power is using social science techniques already proven with recycling and seat belt programs to encourage consumers to save energy, said Mike Bukhin, the vice president of engineering.

"Our users are taking snapshots of data subsets and comparing their data to others' in the community. 'How does my fridge compare to yours?' They also have the ability to ask resident experts questions about their data. The data in turn is shared with the rest of the community," he said.

SAN MATEO, Calif.--Former U.S. Vice President Al Gore hopes that America's next-generation power grid will be a lot like the Internet. Or at least that's the plan.

How close we get to that goal depends on what happens in the next five years, Gore said in a speech here on Thursday evening at blog VentureBeat's GreenBeat conference, where he outlined many of the challenges the United States faces in upgrading its power grid. Along the way, he made comparisons to how the advent of the so-called smart grid will enable the kind of solutions and business innovation that the Internet brought during the 1990s.

"The analogy to the Internet is quite an exact one. Not completely exact, but it's very relevant for lots of reasons.
