GREEN COMPUTING:

 Green computing, also called green technology, is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste). https://www.techopedia.com/definition/14753/green-computing

People use the limited source which is created naturally from where they live it’s the earth. There is no unlimited resource. However, people still use it or waste it in the worse situation. So being and acting ECO (economical) is the trend in the society today. For example, using LED light instead of yellow light, instead of printed paper, data can be stored online and use it over again. Both sides have their advantage, some prefer to print there data because they like to hold what they are reading instead of on a computer. Another example is People that like to read books instead of watching the movie. So, it’s the perspective of the people. Many things can be changed to ECO. And nowadays, people also care about computing so what they do is green computing which is also called green IT.

SUSTAINABILITY:

Development that meets the need of the present without compromising the ability of future generations to meet their own needs.(Brunt-land Report for the world commission on Environment and Development 1992)

Environmental – Science the quality of not being harmful to the environment or depleting natural resources, and thereby supporting long-term ecological balance. The committee is developing sustainability standards for products that use energy. http://www.globalfootprints.org/sustainability

COMPARE TWO COMPUTER SPECIFICATIONS TO DETERMINE THE MOST ENERGY SAVING COMPUTER:

Laptop typically consumes 20-50 watts of electricity that can be trimmed down in power saver modes On the other hand, desktops use about 60-200 watts of electricity. Some of it Differ from its screen. A Cathode Ray Tube screen consumes more than liquid crystal display screens. LCD screens can save up to 75% electricity over a CRT screen. Desktop Computers requires an uninterruptible power supply to keep it running while power loses which can be consumed a great amount of electricity. So, I am going to compare two Computers the most popular laptop in the USA is NEW XPS TOWER SPECIAL EDITION.

NEW XPS TOWER SPECIAL EDITION:

The specification is Memory 16GB, 2400MHz, DDR4; up to 64GB, Processor 7th Generation Intel® Core™ i7-7700 Processor (8M Cache, up to 3.6 GHz).You clearly see that this is not practicing good Green IT.( http://www.dell.com/en-us/shop/dell-desktop-computers/new-xps-tower-special-edition/spd/xps-8920-se-desktop)

 Another one is MAC BOOK PRO.

MAC BOOK PRO.  

  MacBook pro has some environmental specifications. They are High-recyclable almunium and glass enclosure, mercury-free LED-backlit display, arsenic-free display glass, BFR-free PVC-free3, Energy Efficient Ethernet, reduced packaging volume, meets ENERGY STAR Version 5.2 requirements, and rated EPEAT Gold4. About the battery, MacBook pro can be up to 10 hours wireless web, up to 30 days of standby time, it is built-in 54.5-watt-hour lithium-polymer battery with 61W USB-C Power Adapter. (https://www.apple.com/in/macbook-pro/specs/)

 So by comparing two Computers   you can clearly see that Apple Company are practicing safer green IT.

 

METHODS OF PROMOTING GREEN COMPUTING:

 

Be responsible to your technology waste:

The IT industry is one of the leading contributors of what they call e-waste. Constant upgrades are made and it will not only mean better performance but some dumped old technology as well. Have you ever wondered where they now? Keep in mind that materials used in building computers systems are not organic. They will not rot. If buried, they will remain there for years and might even cause pollution if left unattended. There is nothing that we can do about it now. We do not have the authority to create a big move towards a solution to this problem. However, we can start within our family. Teach the younger ones to reuse. You can return a broken keyboard, mouse or any electronic device to the manufacturer so that they can recycle or dispose it properly. Be creative. There are even some who were able make works of art out of these materials. There is nothing impossible as long as we work hard on it and be devoted towards such a wonderful cause.

Buy Energy Efficient Hardware’s:

The U.S. Environmental Protection Agency (EPA) established the ENERGY STAR Program (www.energystar.gov) in 1992 to help consumers save money and protect the environment through energy efficient products and practices. The ENERGY STAR label is on now on over 50 product categories, which from its onset included computers and monitors. https://www.vpit.ualberta.ca/green/?ref=things

ENERGY STAR has an online product search tool to assists people seeking energy efficient desktop and laptop computers.

EPA calculates that if all computers sold in the U.S. meet ENERGY STAR requirements, the savings in energy costs will increase to approximately $2 billion each year. This is equivalent to the greenhouse gas emissions of 2 million cars.

 Use more efficient displays:

If you have old CRT monitors still in use, replacing them with LED displays can save up to 70 percent in energy costs. However, not all LED monitors are created equal when it comes to power consumption. High efficiency LEDs are available from several vendors.

LG recently released what it claims is the world’s most energy efficient LED monitor, the Flatron-W2252TE. Tests have shown that it uses less than half the power of conventional 22-inch monitors.

RENEWABLE ENERGY:

Renewable energy is defined as the energy which is generated from natural resources such as sunlight, wind, rain and geothermal heat.

I strongly recommend solar power which is from sunlight and reduce paper consumption which is use of digital printing.

SOLAR POWER:

Solar panel is now available at a reasonable price, easy to install, very effective and it last long. The cause of this recommendation is because TESCO consumption a lot of energy throughout the day 8-4 for 6 days a week used also for security reason at night, therefore if they had solar panel it would be more energy saving for their benefits on electricity bills. http://listverse.com/2009/05/01/top-10-renewable-energy-sources/

REDUCE PAPER CONSUMPTION:

 Another way to save money while reducing your company’s impact on the environment is to reduce your consumption of paper. You can do this by switching from a paper-based to an electronic workflow: creating, editing, viewing, and delivering documents in digital rather than printed form. Send documents as e-mail attachments rather than faxing. And when printing is unavoidable, you can still reduce waste and save money by setting your printers to use duplex (double-sided) printing. An internal study conducted by HP showed that a Fortune 500 company can save 800 tons of paper per year (a savings of over $7 million) by printing on both sides. This is best for TESCO because Tesco use lots of paper for bills. https://www.techrepublic.com/blog/10-things/10-tips-for-implementing-green-it/
