Power Usage Effectiveness
Power usage effectiveness (PUE) or power unit efficiency is a ratio that describes how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead that supports the equipment). PUE is the ratio of the total amount of energy used by a computer data center facility to the energy delivered to computing equipment. PUE is the inverse of data center infrastructure efficiency. PUE was originally developed by a consortium called The Green Grid. PUE was published in 2016 as a global standard under ISO/IEC 30134-2:2016 An ideal PUE is 1.0. Anything that isn't considered a computing device in a data center (e.g. lighting, cooling, etc.) falls into the category of facility energy consumption. : \mathrm = = 1 + Issues and problems with the power usage effectiveness The PUE metric is the most popular method of calculating energy efficiency.

Water Usage Effectiveness
Water Usage Effectiveness (WUE) is a sustainability metric created by The Green Grid in 2011 to attempt to measure the amount of water used by datacenters to cool their IT assets. To calculate simple WUE, a data center manager divides the annual site water usage in liters by the IT equipment energy usage in kilowatt hours (Kwh). Water usage includes water used for cooling, regulating humidity and producing electricity on-site. More complex WUE calculations are available from The Green Grid website.

Data Center
A data center is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. A large data center is an industrial-scale operation using as much electricity as a medium town. Estimated global data center electricity consumption in 2022 was 240–340 TWh, or roughly 1–1.3% of global electricity demand. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. The IEA projects that data center electric use could double between 2022 and 2026. High demand for electricity from data centers, incl ...

IT Energy Management
IT energy management or Green IT is the analysis and management of energy demand within the Information Technology (IT) department in any organization. IT energy demand accounts for approximately 2% of global emissions, approximately the same level as aviation, and represents over 10% of all the global energy consumption (over 50% of aviation's energy consumption). IT can account for 25% of a modern office building's energy cost. At one point, the main sources of manageable IT energy demand were personal computers (PC)s and Monitors, accounting for 39% of energy use, followed by data centers and servers, accounting for 23% of energy use.Steve Kleynhans, VP Computing, Gartner presentation “the Green PC Environment” - presentation, New York, November 2007 In 2006, US IT infrastructures consumed an estimated 61 billion kWh of energy, totaling to a cost of $4.5 billion. This constitutes about 1.5% of total US electricity consumption Significant opportunities exist for Enterpri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Green Computing
Green computing, green IT (Information Technology), or Information and Communication Technology Sustainability, is the study and practice of environmentally sustainable computing or IT. The goals of green computing include optimising energy efficiency during the product's lifecycle; leveraging greener energy sources to power the product and its network; improving the reusability, maintainability, and repairability of the product to extend its lifecycle; improving the recyclability or biodegradability of e-waste to support circular economy ambitions; and aligning the manufacture and use of IT systems with environmental and social goals. Green computing is important for all classes of systems, ranging from handheld systems to large-scale data centers. Many corporate IT departments have green computing initiatives to reduce the environmental effect of their IT operations.E. Curry, B. Guyon, C. Sheridan, and B.

Gpue
Green Power Usage Effectiveness (GPUE) is a proposed measurement of both how much sustainable energy a computer data center uses, its carbon footprint per usable kilowatt hour (kWh) and it uses its power; specifically, how much of the power is actually used by the computing equipment (in contrast to cooling and other overhead). It is an addition to the power usage effectiveness (PUE) definition and was first proposed by Greenqloud. The Green Grid has developed the Power Usage Effectiveness metric or PUE to measure a data centers' effectiveness of getting power to IT equipment. What the PUE tells in simple terms is how much extra energy is needed for each usable kWh for the IT equipment due to the power going into cooling, power loss etc. and it's a simple formula (in theory): PUE = Total Facility Power/IT Equipment Power The PUE can change depending on where measurements are made, when they are made and the timespan the measurements are made in. Data centers are subtracting fact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Performance Per Watt
In computing, performance per watt is a measure of the energy efficiency of a particular computer architecture or computer hardware. Literally, it measures the rate of computation that can be delivered by a computer for every watt of power consumed. This rate is typically measured by performance on the LINPACK benchmark when trying to compare between computing systems: an example using this is the Green500 list of supercomputers. Performance per watt has been suggested to be a more sustainable measure of computing than Moore's law. System designers building parallel computers often pick CPUs based on their performance per watt of power, because the cost of powering the CPU outweighs the cost of the CPU itself. Spaceflight computers have hard limits on the maximum power available and also have hard requirements on minimum real-time performance. A ratio of processing speed to required electrical power is more useful than raw processing speed. D. J. Shirley; and M. K. McLellan ...

Fortune 100
The ''Fortune'' 500 is an annual list compiled and published by ''Fortune'' magazine that ranks 500 of the largest United States corporations by total revenue for their respective fiscal years. The list includes publicly held companies, along with privately held companies for which revenues are publicly available. The concept of the ''Fortune'' 500 was created by Edgar P. Smith, a ''Fortune'' editor, and the first list was published in 1955. The ''Fortune'' 500 is more commonly used than its subset ''Fortune'' 100 or superset ''Fortune'' 1000. History The ''Fortune'' 500, created by Edgar P. Smith, was first published in January 1955. The original top ten companies were General Motors, Jersey Standard, U.S. Steel, General Electric, Esmark, Chrysler, Armour, Gulf Oil, Mobil, and DuPont.
