Millions of homes to get energy efficiency displays PDF Print E-mail

The days of learning about your electricity consumption once a month are the on the wane.

Driven by consumer interest in energy and utility smart-grid programs, home energy information displays are poised to enter people's kitchens and living rooms in large numbers over the next few years, Pike Research forecast in a report on Thursday.

The research company predicts there will be 28.1 million users of energy displays by 2015. About half of the users will have actual devices, while more than 11 million will access that information from Web-based dashboards and 2.6 million from mobile phones, according to Pike Research.

The purpose of these displays is to guide consumers in lowering their energy consumption. Simply making people aware of their electricity use will drive people to make behavior changes to cut their utility bills and environmental footprint. Studies have found that a combination of more detailed information and utility-run incentive programs can help consumers shave between 5 percent and 15 percent off their bills.

For example, a display might show that electricity usage is above normal at a given moment and send someone to turn off unused electronics. Getting historical data and information on different appliance usage, too, can lead people to make adjustments. More advanced home energy management systems will allow a person to program heating and cooling and to participate in utility efficiency programs to cut energy use during peak times.

Still, since many of these products are still not on the market, it's not clear how effective they will be at improving home energy efficiency and whether consumers will continue to use them regularly.

There are already a number of home energy monitoring devices which can cost anywhere from less than $100 to a few hundred dollars. But the field is getting crowded with a number of providers from very different fields. The smart-grid stimulus program is expected to result in over 1 million homes getting these displays for free from utilities.

Both Microsoft and Google offer Web dashboards, although their functions vary. There are also dozens of companies, including a number of start-ups, which make devices or software to run on displays.

In many cases, information is gathered through a smart meter, which has a two-way communications link with the utility. But in many smart-grid programs, utilities are not making detailed energy usage available to consumers in real time, in part because of security concerns, says smart-grid executives.

Although the home networking standards are still in flux, many energy information display companies are developing gateways using home Internet connections to read existing meter data and software to provide efficiency recommendations to consumers.

The Energy Whip Comes Down on TVs PDF Print E-mail

New Energy Star standards for energy-efficient TVs will save 40 to 65 percent in electricity.

Energy Star, the voluntary energy-efficiency program run by the United States’ EPA, has released the final specifications for much more stringent energy levels for TVs, starting in May 1, 2010, with even stricter standards to follow on May 1, 2012. TVs manufactured after those dates must meet the new requirements to bear the Energy Star logo, which signifies a more energy-efficient product.

The new specs for TVs, called versions 4.0 and 5.0, respectively, are focused mainly around on-mode power consumption. The current Energy Star 3.0 specification that went into effect in November 2008 was the first to require TVs to meet maximum on-mode power consumption levels, though most TVs in the market met the standard and the specification has been considered too lenient.

According to Energy Star, “TVs qualifying for Energy Star under the Version 4.0 specification will offer consumers a savings of more than 40 percent. When the Version 5.0 specification goes into effect, Energy Star-qualified TVs will be as much as 65 percent more efficient than models currently on the market.”

Here’s a breakdown of the current on-mode levels TVs must meet to be Energy Star-certified, and those after May 2010 and May 2012:

20-inch screen
Version 3.0 (current)—66 watts (HDTVs)
Version 4.0 (May 2010)—37 watts
Version 5.0 (May 2012)—27 watts

32-inch screen
Version 3.0 (current)—120 watts (HDTVs)
Version 4.0 (May 2010)—78 watts
Version 5.0 (May 2012)—55 watts

42-inch screen
Version 3.0 (current)—208 watts (HDTVs)
Version 4.0 (May 2010)—115 watts
Version 5.0 (May 2012)—81 watts

50-inch screen
Version 3.0 (current)—318 watts (HDTVs)
Version 4.0 (May 2010)—153 watts
Version 5.0 (May 2012)—108 watts

60-inch screen
Version 3.0 (current)—391 watts (HDTVs)
Version 4.0 (May 2010)—210 watts
Version 5.0 (May 2012)—108 watts

The new specs also require standby power of 1 watt or less (when the TV is off), as well as luminance (brightness) levels and energy requirements for TVs while in data acquisition mode (DAM), like retrieving TV Guide information.

A small allowance in energy use is given to TVs that use automatic brightness control, which can dim a screen depending on the amount of ambient light in the room. About 30 percent of the current Energy Star TVs qualified under this option in the 3.0 specification, says Katharine Kaplan of the Energy Star program.

Interestingly, the luminance requirement is for TVs in a home mode to use no less than 65 percent of the brightness of a retail (also called torch) mode, which uses a higher-power state with high brightness and contrast levels for viewing in retail environments. The reason for this, explains Kaplan, is to prevent a home mode that is too dim and forces users to turn it up, thereby using more electricity.

It will be interesting to see whether the Energy Star requirements spur TVs—especially larger ones and more energy-dependent plasma-based models—to become more efficient. My guess is that many will. The future Energy Star specs, although voluntary, are much more stringent than California’s proposed energy level restrictions for TVs to be sold in that state.

GE to Launch Entire Suite of Net Zero Energy Home Products by 2015 PDF Print E-mail
08.24.2009 — GE wants to be the one-stop shop for energy products.

The company has announced that by 2015 it will develop a turnkey product portfolio that will enable the construction of net zero energy homes using a single supplier.

To achieve that goal, GE plans to add solar PV and residential wind products, along with “demand-response technology” that can allow homeowners to alter usage in real-time, to its existing portfolio of energy-efficient lighting and appliances.

GE Consumer & Industrial president and CEO James Campbell says smart-grid technology is “extremely critical to GE Energy."

The GE net zero energy home offerings will be comprised of three major groups within the product portfolio:
  • Energy Efficient Products—The company offers more than 550 Energy Star appliances and 271 Energy Star lighting models.
  • Energy Generation/Storage Products—Other products by 2015 will include solar PV, advanced energy storage, next generation thin film solar and small wind power.
  • Energy Management Products—GE plans to offer a full suite of demand-response appliances that will work with utility smart meters to help shed load from the grid during peak demand usage and pricing times. The products will work with smart meters to delay or reduce energy use without major interruption to consumer's lifestyles by giving the consumer control over their energy use.

 

Expected Impact


Residential housing consumes 37 percent of the electricity produced in the US. Appliances, lighting and HVAC represent 82 percent of electricity consumed in the home. In 2010, GE will introduce the Home Energy Manager, designed to be the “central nervous system for the net zero energy home” that will work in conjunction with all the other enabling technologies.

In addition, the company will introduce a line of smart thermostats, also available in 2010. Together, the devices will inform consumers when and how they are using energy and empower them to make decisions when they should use energy from the grid, use stored energy, and self generated energy. Up to 31 percent of the homes energy use comes from HVAC.

GE estimates these devices will reduce energy usage up to 30 percent in a typical home. The company will also be introducing highly efficient water heaters that can save the average home $250 per year.
