Green Computing and Sustainability.Pdf GREEN COMPUTING Submitted by ALVIN T VINCENT (FK-2195) PAWAS DAYAL (FN-136) GREEN COMPUTING Green computing is the study and practice of using computing resources efficiently. The goals are similar to green chemistry; that is reduce the use of hazardous materials, maximize energy efficiency during the product͛s lifetime and promote recyclability or biodegradability of defunct products and factory waste. Opportunities lie in green technology like never before in history and organizations are seeing it as a way to create new profit centres while trying to helping the environmental cause. The plan towards green IT should include new electronic products and services with optimum efficiency and all possible options towards energy savings. APPROACHES TO GREEN COMPUTING VIRTUALIZATION: Computer virtualization is the process of running two or more logical computer systems on one set of physical hardware. The concept originated with the IBM mainframe OS of the 1960͛s, but was commercialized for x86- compatible computers only in the 1990͛s.With virtualization, a system administrator could combine several physical systems into virtual machines on one single, powerful system, thereby unplugging the original hardware and reducing power and cooling consumption. POWER MANAGEMENT: Power management for computer systems are desired for many reasons particularly: Prolong battery life Reduce cooling requirements Reduce noise Reduce operating costs for energy and cooling Lower power consumption also means lower heat dissipation, which increases system stability and less energy use which saves money and reduces the impact on the environment. The advanced configuration and power interface (ACPI),an open industry standard, allows an operating system to directly control the power saving aspects of its underlying hardware. This allows a system to automatically turn off components such as monitors and hard drives after set periods of inactivity. In addition, a system may hibernate, where most components (including the CPU and the system RAM) are turned off. Some programs allow the user to manually adjust the voltages supplied to the CPU, which reduces both the amount of heat produced and electric ity consumed. This process is called under Volting. POWER SUPPLY The 80 plus program is a voluntary certification system for power supply manufactures. If a PSU meets the certification, it will use only the power it needs at a given load: In other words, it won͛t use more power than it needs. It͛s the heart of a green PC, since it manages the power for all the other components. An industry initiative called 80 PLUS certificates PSUs that are at least 80% efficient. STORAGE The most conventional route is the 3.5͛͛ desktop hard drive. Recently, major drive manufacturers have begun to focus on reduced power consumption, resulting in such features as the reduced RPM low-power idle mode with fixed rotation speed for reduced power consumption. The second option, which also tends itself to affordability, is to use a 2.5͛͛ laptop hard drive. These consume less power than larger disks as a result of their smaller platters, smaller motors. The lowest-power option is to use a solid state hard drive (SSD), which typ ically draw less than one ʹthird the power of a 2.5͛͛ disk. VIDEO CARD: No video card ʹ use a shared terminal, Use mother board video output ʹ typically low 3D performance and low power. Select a GPU based on average wattage The easiest way is to go for integrated video. This is the lowest-performance option. DISPLAYS: LCD monitors typically use a cold-cathode fluorescent bulb to provide light for the display. Some newer displays use an array of light-emitting diodes (LEDs) in place of the fluorescent bulb, which reduces the amount of electricity used by the display. LCD monitors uses three times less when active, and ten times less energy when in sleep mode. LCDs are up to 66% more energy efficient than CRTs, LCDs are also upwards of 80% smaller in size and weight, leading to fuel savings in shipping. LCDs also produce less heat. MATERIALS RECYCLING: Computer recycling refers to recycling or reuse of a computer or electronic waste. This can include finding another use for the system, or having the system dismantled in a manner that allows for the safe extraction of the constituent materials for reuse in other products. Electronic devices, including audio-visual components, mobile phones and other hand-held devices, and computer components, contain valuable elements and substances suitable for reclamation, including lead, copper, and gold. They also contain a plethora of toxic substance, such as dioxins, PCBs, cadmium, chromium, radioactive isotopes, and mercury. TELECOMMUTING Teleconferencing technologies are often implemented in green computing initiatives. The advantages are many; increased worker satisfaction, reduction of greenhouse gas emissions related to travel and increased profit margins as a result of lower overhead costs for office space, heat, lighting etc. FUTURE OF GREEN COMPUTING As 21st century belongs to computers, gizmos and electronic items and energy issues will get serious ring in the coming days, as the public debate on carbon emissions, global warming and climatic change gets hotter. If we think computers are non polluting and consume very little energy, we need to think again. It is estimated that out of $250 billion per year spent on powering computers worldwide, only about 15% of that power is spent computing-the rest is wasted. Thus, energy saved on computer hardware and computing will equate tonnes of carbon emissions saved per year. Taking into consideration the popular use of information technology industry, it has to lead a revolution of sorts by turning green in a manner no industry has ever done before. GREEN IT: NEXT BURNING ISSUE FOR BUSINESS It is becoming widely understood that the way in which we are behaving as a society is environmentally unsustainable, causing irreparable damage to our planet. Rising energy prices, together with government-imposed levies on carbon production are increasingly impacting on the cost of doing business, making many current businesses practice economically unsustainable. It is becoming progressively more important for all business to act in an environmentally responsible manner, both to fulfil their legal and moral obligations, but also to enhance the brand and to improve corporate image. The whole purpose of IT is to make business more productive and efficient, and to save money. THE PROBLEM Rising energy costs will have an impact on all business, and all businesses will increasingly be judged according to their environmental credentials, by legislators, customers and shareholders. THE SOLUTION A fresh approach to IT and power is now needed, putting power consumption at the force in all aspects of IT ʹ from basic hardware design to architectural standards, from bolt-on point solutions to bottom -up infrastructure build. IBM has a real appreciation of the issues, thanks to its size, experience and expertise, and can help its customers to avoid the ͚wrong ways͛ of doing things, by helping to identify the most appropriate solutions. Modern IT systems provide more computing power per unit of energy and thus reduce energy consumption per unit of computing power. Despite this, they are actually responsible for an overall increase in energy consumption and for an increase in the cost of energy as a proportion of IT cost this is because users are not simply using the same amount of computing hour as before, while using the new technology to reduce their power consumption nor are they using technology to leverage savings in a energy cost. STRATEGIES OF CHANGE Businesses are competitive bodies, used to having to ͚do more with less͛ in order to remain competitive. They will have to learn to use less electricity in just the same the way, using green computing to save money. This will demand major changes in IT uses and policies. Companies will have to take modest steps, simply making sure that desktop PC͛s monitors and printers are turned off at night, and/or using more effective power-saving modes on unused equipments. New dual core processors are faster than traditional chips and yet used less energy, and the latest generation of dual-core processors promise to consume about one third less power than their predecessors while offering up to 80% better performance. Other IT uses may need to investigate the use of DC power. Most energy suppliers provide AC power because it is easier to transport over long distances, although most PC͛s run on DC, so that the AC current has to convert to DC before it reaches the hardware, with inevitable losses of energy in conversion. Virtualization and server consolidation can allow users to ͚do͛ more with less͛, allowing one large server to replace several smaller machines. The US environmental protection Agency͛s Energy Star programme is already promoting more energy-efficient IT infrastructures and polices, while IBM, Hewlett-Packard, Sun Microsystems and AMD have joined forces to launch the Green Grid environment lobby, aimed at reducing energy consumption at computer data centres by encouraging and improving power saving measures. RECENT IMPLEMENTATIONS: BLACKLE It is a search engine site powered by Google search. It came into being on the concept that when a computer screen is white presenting the Google home web page, your computer consumes 74W.When the screen is black it consumes only 59W.Based on this theory if everyone switched from Google to Blackle, mother earth would save 750MW each year. FIT-PC Fit ʹ PC is the size of a paperback and absolutely silent, yet fit enough to run Windows Xp or Linux. Fit-PC is designed to fit where a standard PC is too bulky, noisy and power hungry. Fit-PC draws only 5 Watts, consuming in a day less power than a traditional PC consumes in 1 hour.

    TECHNOLOGY AND COMMUNITY DEVELOPMENT BCD 216 LECTURE 12 DETERMINING A SUSTAINABLE APPROACH (CONT’D) 10) Health care According to the Global Health Council, rather than the use of professionally schooled doctors, the training of villagers to remedy most maladies in towns in the developing world is most appropriate. Trained villagers are able to eliminate 80% of the health problems. Small (low-cost) hospitals - based on the model of the Jamkhed hospital – can remedy another 15%, while only 5% will need to go to a larger (more expensive) hospital.Before being able to determine the cause of the disease or malady, accurate diagnosis is required. This may be done manually (through observation, inquiries) and by specialised tools.Herbalist medicines(e.g. tinctures, tisanes, decoctions) are appropriate medicines, as they can be freely made at home and are almost as effective as their chemical counterparts. A previous program that made use of herbal medicine was the Barefoot doctor program. A phase-change incubator, developed in the late 1990s, is a low cost way for health workers to incubate microbial samples.Birth control is also seen as an appropriate technology, especially now, because of increasing population numbers (overpopulating certain areas), increasing food prices and poverty. It has been proposed to a certain degree by PATH (program for appropriate technology in health).Jaipur leg was developed by Dr. P. K. Sethi and Masterji Ram Chander in 1968 as an inexpensive prosthetic leg for victims of landmine explosions.The Leveraged Freedom Chair is a low-cost wheelchair designed specifically for rough terrain,Natural cleaning products can be used for personal hygiene and cleaning of clothing and eating utensils; in order to decrease illnesses/maladies (as they eliminate a great amount of pathogens).

  • A Novel Method to Enhance Sustainable Systems Security in Cloud Computing Based on the Combination of Encryption and Data Mining
    sustainability Article A Novel Method to Enhance Sustainable Systems Security in Cloud Computing Based on the Combination of Encryption and Data Mining Qian He 1,* and Hong He 2 1 Enterprise Cooperation and International Affairs Office, Hunan Industry Polytechnic, Changsha 410007, China 2 Department of Computer and Communication, Hunan Institute of Engineering, Xiangtan 411101, China; [email protected] * Correspondence: [email protected] Abstract: Due to the increasing growth of technologies and the diversity of user needs in the field of information technology, the position of cloud computing is becoming more apparent. The de- velopment of computing infrastructure in any organization requires spending a lot of money, time, and manpower, which sometimes does not fit into the operational capacity of an organization. There- fore, organizations tend to use such technologies to advance their goals. A fully open and distributed structure in cloud computing and its services makes it an attractive target for attackers. This structure includes multiple service-oriented and distributed paradigms, multiple leases, multiple domains, and multi-user autonomous management structures that are more prone to security threats and vulnerabilities. In this paper, the basic concepts of the cloud computing and its applications have been investigated regarding to the importance of security issues. The proposed algorithm improves the level of security in the cloud computing platform through data mining and decision tree algorithm. Low computational burden and client numbers independency help to effectively implement the proposed algorithm in reality.
