EFFECT IF GREEN COMPUTING IS NOT APPLIED

If green computing is not applied,we as a human being will facing many problem.  one of the problem is global warming.  The planet is warming, from North Pole to South Pole, and everywhere in between. Globally, the mercury is already up more than 1 degree Fahrenheit (0.8 degree Celsius), and even more in sensitive polar regions. And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice, it’s also shifting precipitation patterns and setting animals on the move.

Some impacts from increasing temperatures are already happening.

• Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
• Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
• Sea level rise became faster over the last century.
• Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
• Precipitation (rain and snowfall) has increased across the globe, on average.
• Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.

Other effects could happen later this century, if warming continues.

• Sea levels are expected to rise between 7 and 23 inches (18 and 59 centimeters) by the end of the century, and continued melting at the poles could add between 4 and 8 inches (10 to 20 centimeters).
• Hurricanes and other storms are likely to become stronger.
• Species that depend on one another may become out of sync. For example, plants could bloom earlier than their pollinating insects become active.
• Floods and droughts will become more common. Rainfall in Ethiopia, where droughts are already common, could decline by 10 percent over the next 50 years.
• Less fresh water will be available. If the Quelccaya ice cap in Peru continues to melt at its current rate, it will be gone by 2100, leaving thousands of people who rely on it for drinking water and electricity without a source of either.
• Some diseases will spread, such as malaria carried by mosquitoes.
• Ecosystems will change—some species will move farther north or become more successful; others won’t be able to move and could become extinct. Wildlife research scientist Martyn Obbard has found that since the mid-1980s, with less ice on which to live and fish for food, polar bears have gotten considerably skinnier.  Polar bear biologist Ian Stirling has found a similar pattern in Hudson Bay.  He fears that if sea ice disappears, the polar bears will as well. 

Therefore, green computing should be applied by every individual to prevent from global warming occur. 

15 ECO FRIENDLY CONCEPTS COMPUTERS FOR GREEN COMPUTING IN FUTURE

Technology advancements are known to make what was new today appear obsolete tomorrow. Developments in the field of Information Technology are today happening so fast that computers come into the market and are soon rendered a piece of junk as well. This has therefore given rise to a new field of computing known as Green Computing, which encourages the use of environmentally sustainable computers, and accessories which during usage and disposal cause minimal or no harm to the environment. Also referred to as Green IT, this technology aims to increase energy efficiency and reduce the use of hazardous chemicals in hardware designing which in turn when disposed or recycled do not harm the environment. Latest O Project Dell personal computer concept is really green!

Green Prospects and Our Role

Green IT is both an economic and environmental imperative. Several case studies on greening efforts reveal that businesses that reduce their environmental (carbon) footprints can also reduce costs and improve their public images. IT professionals, CIOs, and IT support staff are thus being called upon to deliver environmentally sustainable IT solutions. Even simple steps by one individual or organization can make a huge difference when leveraged across the vast number of individuals and organizations across the world. Smart companies will adopt innovative environmental strategies to innovate, create value, and build a competitive advantage.
Triggered by the imminent introduction of more green taxes and regulations, there will be a major increase in demand for green IT products and solutions in the near future. The greening of and by IT will continue to be a necessity, not an option.
IT professionals, educators, researchers, and businesses can make a difference and help create a sustainable environment that benefits current and future generations. Albert Einstein once said, "The significant problems we have cannot be solved at the same level of thinking with which we created them." I hope this issue of Computing Now helps you to develop a green mindset and motivates you to do what you can to make IT and its use greener. I invite you to share your research findings, views, and ideas on this topic, as well as best practices and your experiences in greening IT.

The Easy Ways To Go Greening Computing

1. Shutdown Your Computer Without Losing The Perks of Always-On PC  

Obviously, computers require electricity to run, so shutting down, sleeping, or hibernating your computer when you're not using it conserves energy. Every modern operating system has its own settings for conserving power, so the first thing you should do—if you haven't already—is open the power settings of your computer and set them for optimal energy use. Set your computer to put your monitor to sleep, spin down your hard drives, and put your computer to sleep when you're not using it. Even better, since your computer uses less power when hibernating than when sleeping, set up your computer to hibernate rather than just go to sleep.

One of the biggest turn-offs (no pun intended) about shutting down or sleeping your computer is that you miss out on some of the finer things your computer provides even when you're away. For example, if you're downloading a large file, you may want the download to continue even when you're away. Likewise, we've covered tons of ways to remotely access your computer, all of which no longer work if your computer's turned off. Luckily you can continue using your computer during these times but still conserve power the rest of the time.

For example, Windows users should check outpreviously mentioned WinOFF, which shuts down, restarts, and hibernates your computer (among other things) after a certain amount of time, at a specific time, or when your CPU goes idle so that your computer automatically shuts off at times you don't need it.

If a download is what you're waiting for, many peer-to-peer clients, like the popular BitTorrent client uTorrent, can shutdown your computer when a download completes so you can get your file and save energy, too.

Between WinOFF and built-in shutdown features common to many apps, we've taken care of the the download problem—but what about when you want to access your computer remotely? If it's shut down, you can't very well get to it, can you? Actually, you can, assuming you set up Wake-on-LAN on your computer. Once Wake-on-LAN's enabled, you can turn your computer on over the internet from anywhere—so there's no reason not to shut down your computer when you leave the house.

Finally, if you're on a Mac laptop, check out previously mentioned SmartSleep to enhance your power-saving options.

2. Save Paper when Printing

When it comes to the environment, one of the first places most offices can improve is the giant pile of discarded paper by the network printer. Aside from obvious things you can do on your own—like printing duplex, printing to PDF, previewing before printing, and not printing hundreds of copies of an email forward to plaster around the office—there are a few other tools you can use to minimize wasting paper and ink when printing.

To save ink and paper when you're printing from your browser, use previously mentioned Firefox extension Aardvark to tweak the layout of a page and remove elements—like ads and images—that you don't need on the printed page.

When you're not printing from the browser, Windows users can save tons on ink and paper with previously mentioned GreenPrint, a freeware application that automatically identifies and removes unnecessary pages or space from your printouts before they head to the printer.

If you're regularly sending documents back and forth to other people or businesses, you can also save a few trees and save a little time in the process with a couple of office hacks. For example, rather than going through the age-old print, sign, and fax dance handed down through the generations by our forefathers, try creating a scanned signature and thensending scanned PDFs rather than faxes. It's quicker and it saves on resources and costs.

3. Turn Off Peripherals to Kill the Vampires

Now that you've put good energy practices into use on your PC, it's time to move onto the power-hungry peripherals you've got plugged into it. Whenever possible, you want to turn off any peripheral when you're not using it—like your printer or monitor. Likewise, you should be aware of any gear in your computing setup that draws standby power (a.k.a., vampire power) even when you've turned off the device in question. Vampires commonly stand out as large, unsightly AC adapters.

While you could diligently unplug your wall warts or keep them plugged into a power strip that you switch off when they're not in use, you can go even further and automate the process with gadgets like the Energy Saving Smart Strip (original post) and the Power Minder (original post), both of which monitor your PC's power state and automatically shut down other peripherals when you turn off your computer.

4. Estimate Your Power Usage

It's one thing to know your computer sucks down a lot of energy every month, but actual power usage numbers drives the point home. Windows can install previously mentionedLocalCooling, an tool that both helps you tweak your Windows power saving settings and visualize the amount of power your computer consumes. Some users reported inaccurate measures with the app when we first posted about it, but the well-intentioned LocalCooling team continues in their efforts to improve the application and help you save energy and visualize the impact of your energy-saving.

If LocalCooling's not giving you accurate results or you want to get a more definitive look at your PC's power consumption, regardless of your operating system, this Coding Horror postdemonstrates in detail how to determine and lower the cost of leaving your PC running (original post).

WHAT IS GREEN COMPUTING?

Green computing 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).

One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in hardware of all kinds. The Energy Star label became a common sight, especially in notebook computers and displays.
