PDF | The concept of green computing has begun to spread in the past few years, gaining increasing popularity. Besides the widespread sensitivity to ecological. PDF | As computing becomes increasingly pervasive, the energy consumption The topic of this paper, Green Computing is especially important in this regard. Introduction. What is Green-Computing (Green-ICT)?. Green Computing refer to 2 different things. 1 Reducing energy consumption of ICT.

Virtualization is a method of running multiple independent vii. Big in Section4 how this process is involved. Even if they are concerned about the concept they will wait until the cost is recovered from the old infrastructure. Individual rationality however, does consequences of their purchasing decisions. Finally improving the hardware which consume less power. Apple is on track to eliminate toxic chemicals from our products.

The reuse of such equipments environment is to introduce policies all around the World, so allows saving energy and reducing impact on environment, that, companies design products to receive the eco-label [7]. These organizations provide C. According to DoE's current infrastructure services were considered low cost and available.

With environments and the reason for this shift is due to growing the purpose of reducing energy consumption in Data Centers it computing needs, energy cost and global warming. This shift is worthwhile to concentrate on following [4]: At one extreme it is the processing power that is building Green Data Centers. As per green important to business and on the other extreme it is the drive, computing best practices efficient servers, storage challenge of environment friendly system, and infrastructure devices, networking equipments and power supply limitations [9].

Green Computing challenges are not only for selection play a key role in design of information IT equipments users but also for the IT equipments Vendors. The HP rp exceeds U. Energy Star 4. Dell is speeding up its programs needs for cooling dictates. IBM is working on technology to develop cheaper and more efficient solar cells plus many other D. According to One of the main trends of Green Computing is virtualization researchers of Green Computing following are few prominent of computer resources.

Abstraction of computer resources, challenges that Green computing is facing today [9]: This form of Green Computing will lead to equipments; Server consolidation and enhance computer security [6]. The future of Green Computing is going to be based on efficiency, rather than reduction in consumption [10]. Leveraging Unused Computer Resource interest in energy cost reduction, at Data Centers and at One of the exiting areas where Green Computing can grow desktops, and the result of which is the corresponding is the share and use efficiently the unused resources on idle reduction in carbon generation.

The secondary focus of Green computers. Leveraging the unused computing power of IT needs to focus beyond energy use in the Data Center and modern machines to create an environmentally proficient the focus should be on innovation and improving alignment substitute to traditional desktop computing is cost effective with overall corporate social responsibility efforts.

This option. This makes it possible to reduce CO2 emissions by up secondary focus will demand the development of Green to 15 tons per year per system and reduce electronic waste by Computing strategies.

There are few F. Data Compression efforts, which all enterprises are supposed to take care of [2]: In enterprise, huge amount of data that is stored is someway or other duplicated information. Information System backups A. Certifications are true example of such duplicated data. Intelligent There are several organizations providing certificates to compression techniques can be used to compress the data and green technology.

Vendors are based on their product quality, eliminate duplicates help in cutting the data storage material, life of the product and recycling capabilities. In requirements. Applications International Science Index Vol: Green Computing is a diverse field and due to its nature and priority from all fields of life Green Computing has B. Cloud Computing applications in every sector of computing as the goal is to save Cloud Computing has recently received significant attention the environment and ultimately the life.

The current main [11], as a promising approach for delivering Information and applications of Green Computing are covering following Communication Technology services by improving the computing sectors [15]: Product Longevity Technology is not a passive observer, but it is an active As per Gartner and Fujitsu reports on product life cycle it is contributor in achieving the goals of Green Computing. Equipment recycling, reduction of paper usage, objectives [13].

Long life of product will allow more virtualization, cloud computing, power management, Green utilization of products and it will put a control on unnecessary manufacturing are the key initiatives towards Green manufacturing of products.

It is obvious that government computing. Current challenges to achieve Green Computing regulations will push the products vendors to make more are enormous and the impact is on computing performance.

Government regulations are D. Power Management Tools pushing Vendors to act green; behave green; do green; go Power management is proving to be one of the most green; think green; use green and no doubt to reduce energy valuable and clear-cut techniques in near future to decrease consumptions as well. All these efforts are still in limited energy consumption. IT departments with focus on saving areas and currently efforts are mainly to reduce energy energy can decrease use with a centralized power management consumption, e-Waste but the future of Green Computing will tool.

This considers social responsibility, economic viability and the impact on the environment. Many businesses simply focus on a bottom line, rather than a green Triple bottom line, of economic viability when it comes to computers. The idea is to make the whole process surrounding computers friendlier to the environment, economy, and society.

This means manufacturers create computers in a way that reflects the triple bottom line positively. The idea is to make computers from beginning trend a green product. Green computing is the study and practice of using computing resources efficiently.

The primary objective of such a program is to account an expanded spectrum of values and criteria for measuring organizational and societal success. Figure 2. Green Earth[11] Modern IT systems rely upon a complicated mix of people, networks and hardware; as such, a green computing initiative must be systemic in nature, and address increasingly sophisticated problems.

Elements of such a solution may comprise items such as end user satisfaction, management restructuring, regulatory compliance, disposal of electronic waste, telecommuting. Environmental Protection Agency launched Energy Star, a voluntary labeling program that is designed to promote and recognize energy- efficiency in monitors, climate control equipment, and other technologies.

Concurrently, the Swedish organization TCO Development launched the TCO Certification program to promote low magnetic and electrical emissions from CRT-based computer displays; this program was later expanded to include criteria on energy consumption, ergonomics, and the use of hazardous materials in construction.

Organizations use the Green Computing Lifecycle when designing and implementing green computing technologies. Many governmental agencies have continued to implement standards and regulations that encourage green computing.

The Energy Star program was revised in October to include stricter efficiency requirements for computer equipment, along with a tiered ranking system for approved products.

Present Scenario[12][1] There are currently many nations that have established state-wide recycling programs for obsolete computers and consumer electronics equipment The statutes either impose a fee for each unit sold at retail Advance Recovery Fee model , or require the manufacturers to reclaim the equipment at disposal Producer Responsibility model.

Roads to Green Computing Figure 2. Green manufacturing: Regulation and Industry Initiative 2. From the Government: The directives placed responsibility on manufacturers for the gathering and recycling of old equipment the Producer Responsibility model. From the Industry: Climate Savers Computing Initiative: The CSCI provides a catalog of green products from its member organizations, and information for reducing PC power consumption.

It was started on Green Computing Impact Organization Inc.: GCIO is a non-profit organization dedicated to assisting the end-users of computing products in being environmentally responsible.

This mission is accomplished through educational events, cooperative programs and subsidized auditing services. The heart of the group is based on the GCIO Cooperative, a community of environment ally concerned IT leaders who pool their time, resources, and buying power to educate, broaden the use, and improve the efficiency of, green computing products and services Green Electronics Council: On , President George W.

The Green Grid: It is a global consortium dedicated to advancing energy efficiency in datacenters and business computing ecosystems. It was founded in February by several key. The Green Grid has since grown to hundreds of members, including end users and government organizations, all focused on improving data center efficiency. Demons behind Green Computing Power supply: As of July 20, , all new Energy Star 4.

Smaller form factor e. Unlike hard disk drives, solid store detain flash memory or DRAM. With no moving parts, power consumption may be reduced somewhat for low capacity flash based devices. Flash based drives are generally slower for writing than hard disks. Video card: A fast GPU may be the largest power consumer in a computer. Energy efficient display options include: No video cards used in a shared terminal, shared thin client, or desktop sharing software if display required.

Use motherboard video output - typically low 3D performance and low power. Reuse an older video card that uses little power; many do not require heat sinks or fans. Select a GPU based on average wattage or performance per watt. Computer systems that have outlived their particular function can be repurposed, or donated to various charities and non-profit organizations. However, many charities have recently imposed minimum system requirements for donated equipment.

Additionally, parts from outdated systems may be salvaged and recycled through certain retail outlets and municipal or private recycling centers. Computing supplies, such as printer cartridges, paper, and batteries may be recycled as well. 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.

Chilling of data: To keep servers at the right temperature, companies mainly rely on air conditioning. The more powerful the machine, the more cool air needed to keep it from overheating. By , the energy required to power and cool servers account ted for about1. S electricity conception. By , half of the Forbes Global companies will spend more on energy than on hardware such as servers.

Recent implementations of Green Computing Blackle: Blackle is a search-engine site powered by Google Search. Blackle came into being based on the concept that when a computer screen is white, presenting an empty word or the Google home, 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 saveMW each year. This was a really good implementation of Green Computing.

The principle behind Blackle is based on the fact that the display of different colors consumes different amounts of energy on computer monitors. Fit-PC is designed to fit where a standard PC is too bulky, noisy and power hungry.

Zonbu Computer: The Zonbu is a new, very energy efficient PC. The Zonbu consumes just one third of the power of a typical light bulb. The device runs the Linux operating system using a1. It also contains no moving parts, and does even contain a fan. Sunray thin client: Sun Microsystems is reporting increased customer interest in its Sunray, a thin desktop client, as electricity prices climb, according to Subbed Banat, vice president and chief engineer in the Eco Responsibility office at Sun.

Thin clients like the Sun Ray consume far less electricity than conventional desktops, he said. A Sun Ray on a desktop consumes 4 to 8 watts of power, because most of the heavy computation is performed by a server. Sun says Sunrays are particularly well suited for cost- sensitive environments such as call centers, education, healthcare, service providers, and finance.

PCs have more powerful processors as well as hard drives, something thin clients don't have.

Thus, traditional PCs invariably consume a substantially larger amount of power. In the United States, desktops need to consume 50 watts or less in idle mode to qualify for new stringent Energy Star certification. The Asus Eee PC and other ultra-portables: The "ultra-portable" class of personal computers is characterized by a small size, fairly low power CPU, compact screen, low cost and Innovations such as using flash memory for storage rather than hard drives with spinning platters.

These factors combine to enable them to run more efficiently and use less power than a standard form factor laptop. The Asus Eee PC is one example of an ultraportable. It runs Linux too. Companies implementing System Wide Green Computing and employees and individuals practicing individual green computing techniques help in a long way in creating an impact to save the planet. Summary Chapter 2 Deals with Green Computing detailing. It also leads to serious cost savings overtime. Devices use less and less power while renewable energy gets more and more portable and effective.

New green materials are developed everyyea0r, and many toxic ones are already being replaced by them. The features of a green computer of tomorrow would be like: Green computer will be one of the major contributions which will break down the 'digital divide', the electronic gulf that separates the information rich from the information poor.

Our so called technically successful world almost sounds fake. Today almost all streams weather its IT, medicine, transportation, agriculture uses machines which indirectly requires large amount of power and money for its effective functioning. Therefore consumption of energy sources has a negative reaction on the environment. Data centers use a large amount of power and consequently cooling energy is needed to counteract the power usage.

It can be an endless circle of energy waste Hence the Three main reasons that made us realize the need for growing green are: Release of harmful gases from electronics.

More utilization of power and money. Increase of E-waste and improper disposal. Figure 3. Through Virtualization, a system administrator can combine several physical systems into virtual machines on one single, powerful system, thereby reducing power and cooling consumption.

In the longer run, more profits and less expenses. Normally, we think of gas guzzling cars, factories, pesticides, and such when considering environmental concerns. Millions of computers are dumped into landfills each year.

That equates to a lot of lead, cadmium, mercury and brominates flame retardants, which will contaminate both water and air. Component Wattage[19] 3. As computers have become more numerous and the cost of hardware has declined relative to the cost of energy, the energy efficiency and environmental impact of computing systems and programs has received increased attention.

The Green list, rates supercomputers by energy efficiency. This allows a system to automatically turn off components such as monitors and hard drives after set periods of inactivity. As of July20, , all new Energy Star 4. Unlike hard disk drives, solid-state drives store data in flash memory or DRAM. 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.

Recycling computing equipment can keep harmful materials such as lead, mercury, and hexavalent chromium out of landfills, but often computers gathered through recycling drives are shipped to developing countries where environmental standards are less strict than in North America and Europe.

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. The savings are significant; the average annual energy consumption for U.


Other related initiatives, such ash telling, reduce the square footage per employee as workers reserve space only when they need it. Many types of jobs — sales, consulting, and field service — integrate well with this technique. Apple cycle[21] Four areas of particular attention are product and packaging design, materials, energy efficiency, and recycling. Each aspect of the design cycle provides significant challenges, yet our efforts in these areas have resulted in some impressive results.

Product design: It all begins here. Reducing the environmental impact of our products starts with the product design phase.

Design dictates the quantity of raw materials swells the type and recyclability of materials used. It also determines how much energy is consumed during manufacturing and product use.

For example, the amazingly slim inch iMac is made from highly recyclable glass and aluminum and it is so energy efficient it consumes about the same amount of power as a standard light bulb when on. In addition to the substances that have already been restricted or eliminated, Apple is removing elemental forms of bromine and chlorine from our products, not just polyvinylchloride PVC and brominated flame retardants BFRs. The new MacBook family also uses mercury-free light-emitting diode LED displays, with arsenic -free display glass.
