Google PowerMeter
Google PowerMeter was a software project of Google's philanthropic arm, Google.org, to help consumers track their home electricity usage. The development of the software was part of an effort by Google to invest in renewable energy, electricity grid upgrades, and other measures that would reduce greenhouse gas emissions. It was launched on October 5, 2009 and ended on September 16, 2011. The software was designed to record the user's electricity usage in near real-time. According to the company, if half of America's homes' energy use was cut by ten percent, it would equal the average energy used by eight million cars. It was hoped that this tool would raise the home-owner's awareness of how much energy they use and make users more energy efficient. PowerMeter was intended for use with smart meters able to track electricity usage in more detail than standard electric meters. According to Google, in 2009 there were approximately 40 million smart meters in use worldwide. By early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nonintrusive Load Monitoring
Nonintrusive load monitoring (NILM), or nonintrusive appliance load monitoring (NIALM), is a process for analyzing changes in the voltage and current going into a house and deducing what appliances are used in the house as well as their individual energy consumption. Electric meters with NILM technology are used by utility companies to survey the specific uses of electric power in different homes. NILM is considered a low-cost alternative to attaching individual monitors on each appliance. It does, however, present privacy concerns. Background and theory Nonintrusive load monitoring was invented by George W. Hart, Ed Kern and Fred Schweppe of MIT in the early 1980s with funding from the Electric Power Research Institute. The basic process is described in . As shown in figure 1 from the patent, a digital AC monitor is attached to the single-phase power going into a residence. Changes in the voltage and current are measured (i.e. admittance measurement unit), normalized (scaler) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kill A Watt
The Kill A Watt (a pun on '' kilowatt'') is an electricity usage monitor manufactured by Prodigit Electronics and sold by P3 International. It measures the energy used by devices plugged directly into the meter, as opposed to in-home energy use displays, which display the energy used by an entire household. The LCD shows voltage; current; true, reactive, and apparent power; power factor (for sinusoidal waveform); energy consumed in kWh; and hours connected. Some models display estimated cost. Having a NEMA 5-15 plug and receptacle, and rated for 115 VAC (maximum 125 VAC), the Kill A Watt is sold for the North American market. The unit is manufactured by the Taiwanese company Prodigit, which also makes 230 VAC models of similar appearance and functionality for European Schuko, U.K. BS 1363 and Australian AS 3112 receptacles, and a model compatible with 100 VAC for the Japanese market (2022-04, marketed there as the Watt Checker ットチェッカーPlu ...

Energy Management Software
Energy Management Software (EMS) is a general term and category referring to a variety of energy-related software applications which may provide utility bill tracking, real-time metering, building HVAC and lighting control systems, building simulation and modeling, carbon and sustainability reporting, IT equipment management, demand response, and/or energy audits. Managing energy can require a system of systems approach. Energy management software often provides tools for reducing energy costs and consumption for buildings, communities or industries. EMS collects energy data and uses it for three main purposes: Reporting, Monitoring and Engagement. Reporting may include verification of energy data, benchmarking, and setting high-level energy use reduction targets. Monitoring may include trend analysis and tracking energy consumption to identify cost-saving opportunities. Engagement can mean real-time responses (automated or manual), or the initiation of a dialogue between occupants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cent-a-meter
A home energy monitor provides feedback on electrical energy use. Devices may also display cost of energy used, and estimates of greenhouse gas emissions. Various studies have shown a reduction in home energy use of 4-15% through use of home energy display. Electricity use may be measured with an inductive clamp placed around the electric main, via the electric meter (either through an optical port, or by sensing the meters actions), by communicating with a smart meter, or by direct connection to the electrical system. The display portion may be remote from the measurement, communicating with the sensor using a cable, network, power line communications, or using radio. Online displays are also available which allow the user to use an internet connected display to show near real-time consumption. A means to reduce household energy consumption is to provide real-time feedback to homeowners so they can change their energy use. In 2010, UK based Current Cost announced a partner ...
