77 Best Green Tips of the Year

green_planet_300

I set out to find the best green tips of 2008. Unlike Conan the Barbarian, I may not know what is best in life. I do, however, know a good tip when I see one. My qualifications for what is best are based on originality, timeliness and uniqueness. The best tips, such as eating locally, changing your filters, riding the train and switching to a hybrid are far too obvious for this list. You can find those tips anywhere. This list is composed of 77 little-known, oft-overlooked and timely tips.

  1. Use a wind-up alarm clock. That’s a tip straight from the UN.
  2. Learn how to pick a hybrid car. This isn’t exactly that novel, but it sure is timely for prospective hybrid owners. Hey. Leave me alone. It’s way up high on top of the list. There are a lot of tips here.
  3. A youthful face without Botox is only a supermarket trip away.
  4. Don’t flush medicine down the toilet. Dispose of it properly or use it as prescribed.
  5. Give yourself stitches. Personally, I’d probably need more stitches after I gave myself stitches.
  6. Befriend a duck. It’s a morality tale.
  7. Don’t shop around for gas in the city.
  8. Support Child Labor. It’s not what you think. But it could be, so you should see what it is.
  9. Ride the slipstream. Kind of dangerous but interesting nonetheless.
  10. Now that the housing market is in the tank, renting is rising in popularity. Going green is possible for renters and condo dwellers.
  11. Clean your dusty car to reduce its carbon footprint. All that dirt is holding you back. It’s doing nothing for your image either.
  1. Learn what a hippie is. Nobody likes being called a hippie, except hippies.
  2. Cuddle to stay warm. This is a cute one.
  3. Narrow your margins. But expand your horizons.
  4. Install a foam insulating gasket. One of my personal favorite tips.
  5. Use Apple Cider Vinegar to kill head lice. Or just use it to clean your scalp.

  7. Learn How to shop for vintage clothes. Useful for those eco and fashion conscious.
  8. Use Twitter’s GreenStream.
  9. Tweak your tailgate. You can reduce drag caused by your tailgate and improve fuel efficiency by 3-7%.
  10. Bothered by pesky flies? You can use apple cider vinegar to rid yourself of those varmints.
  11. Rethink the way we build our bathrooms. Why do they always look like a tile-covered dungeon?
  12. A recent study found that many people are hesitant to bike to work because they can get all sweaty. This video tip may help.
  13. Inflate your tires. I know this is neither novel or original, but it played a part in the 2008 election. Therefore, it is current.
  14. Go green and earn tax breaks.
    7 green jobs that can make you rich. Sign me up.
  15. Don’t eat farmed fish. Here’s another reason not to eat farmed fish.

  18. Green your iPod. If you’ve digitized all your music, you might as well take another step towards the green.
  19. Toilet train your cat. This tip comes from jazz musician Charles Mingus. Kitty litter is bad for the environment. (Blast from the past tip.)
  20. Take off your shoes when you enter the house. Way to go green, Mom.
  21. Create a ball of soap from leftover soaps. And you thought it was only a Simpsons joke.
  22. Use the old baking soda/vinegar trick to blast open clogged drains. It’s like a fun-time volcano that clears your clog.
  23. Have your friends over for a clothing swap party. Uhm, you shouldn’t be wearing the clothes that you plan to swap. It’s not that kind of swap party.
  24. Don’t wash your car at home. The carwash is actually greener.
  25. Don’t kill spiders. Running away in fear is the green and yellow alternative.
  26. Use your iPhone to save you gas. Looking for that excuse to get an iPhone?
  27. Turn old calendars into photo albums. It’s a great way to collect photos as you go.
  28. Use GPS to save gas. Getting lost is a waste of fuel and a drag.
  29. Cool your home with ice. If that’s not your bag, here’s a way to cool your home with ice energy.
  30. Use garlic to prevent cancer. Garlic can also fight off vampires. (I am aware that they are not real.)

  7. Blog with solar power. This means some bloggers will have to actually go outside.
  8. Ventilate your laser printer. They produce VOC’s.
  9. How to riposte anti-green sentiment. The comeback “Well, that’s just, like, your opinion, man.” Did not make the cut.
  10. Use vodka to treat poison ivy. My childhood would have been a lot less itchy if my parents would have just given me some vodka. Talk about strict.
  11. How to find a green job. In this economy, every little tip counts.
  1. Use praying mantises to control garden pests. Mantises rule!
  2. Don’t hoard coins. Seems like an honest enough thing to do, but it actually causes quite the problem.
  3. Work at a computer? Put a cactus in front of that computer. You were going to do that anyway? No. Well, I still like you.

Green Pastures

 

Green Pastures for Your Old PC

Sometimes, it seems your computer has about the same life span as a goldfish: No sooner have you loaded up your PC with your favorite programs, photos, videos, and music than it’s time to upgrade to a more powerful system, with more storage and better features. That can lead to a glut of PCs ready for the landfill – what recycling experts call e-waste (see “E-Waste by the Numbers” below). In 2006, for example, Americans threw away 44 million PCs and TVs, according to the recycling group Earth 911. Not only does this equipment remain undegraded for centuries, but its toxic components – including cadmium from semiconductors and cases, mercury from flat-panel displays, and flame retardants from plastic – can leach into groundwater.

Sadly, many people don’t realize that much of this waste and pollution is preventable. These not-so-old computers can go on to lead useful second lives with people who don’t need the latest and greatest systems-like primary- and secondary-school students who run undemanding educational software, and nonprofits that do simple word processing and accounting. Here are some easy ways to share your old equipment and keep it out of landfills.

E-wase by the Numbers

Number Event
400,000,000 Number of electronic items discarded in the U.S. each year.
100,000 Number of computer in the U.S. taken out of use every day.
2,630,000 Tons of e-waste generated in the U.S. each year.
2,301,250 Tons of e-waste that goes to landfills.
12.5 Percentage of e-waste that is recycled.
50 to 80 Percentage of e-waste that is exported.
1,000 Number of materials needed to build a typical PC.
40 Percentage of heavy materials in landfills that comes from electronics.

Donate to a National Organization

The best-known national computer charity is the National Cristina Foundation, which acts as matchmaker between you and nearby schools, charities, and not-for-profit public agencies that use your old equipment for education and training. To properly match equipment and recipient, you have to provide basic system specs such as manufacturer and model, processor type, operating system, and amount of memory, and NCF accepts only Pentium III-based PCs and above.

That last requirement may seem odd, but it’s not unusual to find charities a little selective about what they take. And why not? With so many used computers floating around, they can afford to favor newer, well-equipped models. So before you start recycling, pull out your old manual or sales invoice (you still have them, right?) and review your computer’s components.

Recycles.org acts as a clearinghouse for donated equipment, too. After they list the products you’re donating, any of their registered, independently operated charities can request the equipment. Recycles then puts the two of you together by e-mail.

The On It Foundation works with existing organizations, such as Boys and Girls Clubs, to provide computers (along with training and Internet access) to low-income families.

Finally, some local Goodwill Industries, which offer education and training to disadvantaged individuals, accept PCs and components. They train people to refurbish computers for resale and to disassemble non-working equipment into recyclable components.

Donate to a Local Organization

The easiest way to donate your old equipment locally is to go to a nonprofit list aggregator like TechSoup. Type your zip code to get a list of recipients eager to reuse or refurbish your PC and peripherals.

Earth 911 offers a similar list. Specify the type of equipment you want to donate along with your Zip code in the green box at the top of the page. It also offers a calendar of hazardous waste recycling events in your area (in the right-hand column of your search results).

Earth 911Earth911.org not only lists local recyclers, it also lists local recycling events.

Finally, Computers for Schools directs you to local organizations that refurbish and certify used PCs. These groups then sell the equipment to schools and nonprofits for about one-third the cost of a new system.

Send It Back to Its Maker

Here’s a bit of good news: Computer manufacturers are slowly but surely taking responsibility for the full lifecycle – from birth to death – of the PCs they build. Check the Web site of your computer’s manufacturer to see if it has a take – back program. Alternatively, you can check the EPA’s useful summary or visit eBay’s Rethink Initiative page, which reviews the recycling programs of major manufacturers.

Dell and Apple lead the way. Dell recycles any Dell PC for free and pays the shipping costs. They’ll also recycle any old PC if you buy your new one from Dell. Apple, too, takes back any computer or monitor and pays for shipping when you buy a new Apple computer or monitor. Sony and Toshiba accept old computers and prepay for shipping, but for their own products only.

HP, on the other hand, charges a fee of $13 to $34 to recycle PCs, printers, and all-in-one devices, while Lenovo’s similar program costs $30.

Some retail stores are even getting into the act. Best Buy is running a test program at 117 stores in eight states, which accept up to two electronic devices for recycling per person per day, including big items such as TVs and computers. And Staples promotes a recycling program that can earn you store credit.

Trade It In

If you’re at home in the world of eBay and PayPal, you can try trading in your old computer for credit. eBay’s EZTradeIn program can turn your gear – desktop, laptop, monitor, server, game console, and so on-into PayPal cash. You register, use the estimator to get an instant quote for your equipment, preprint a shipping label, then send in your device. Once it arrives, experts evaluate its condition and assign it a final value, which is credited to your PayPal account. The amount may not be huge, but you’re still doing your part to keep the machine out of the landfill – Dealtree, the company that handles the trade-in program for eBay, resells working products and sells non-working products as-is or recycles, donates, or keeps them for spare parts.

Pass It On

Still stumped on what to do with your old computer? Here are some last – ditch suggestions – anything to keep it out of the dump!

  • Sell it on eBay, but make sure it’s worth it for you to go through the trouble of shipping a cumbersome and weighty PC or peripheral.
  • Sell it or give it away locally on Craigslist.
  • Explore the Freecycle Network, a worldwide community of more than half a million people who list stuff they want to give away (no money ever changes hands) in the hopes of keeping junk out of landfills. While effective, Freecycle’s a bit complex (it’s built around Yahoo! Groups technology and you have to register to participate), but it’s worth a peek.
  • Put up a flyer at your church or supermarket.

Dump It the Right Way

What if your computer is simply too old or damaged to be donated, resold, or refurbished, and you don’t feel like going to the trouble of shipping it off for proper recycling? Deal with it at curbside: call your local sanitation department to find out if and when your town offers e-waste pickup. If they won’t come to you, find out if your community schedules drop-off events.

A couple of years from now, as states and municipalities institute all sorts of statutes that require recycling in one form or another, you may find it virtually impossible to throw away electronics. (You can take a look at existing ordinances here.) Why all the fuss? Because if you toss out your computer and monitor with the trash and it goes to your town’s landfill, the lead, mercury, and every other toxic component in the equipment can leach into your local water supply and eventually find its way to your tap (see the table, “A Toxic Brew Inside Your Computer”).

Electronic devices are full of potentially toxic substances that must be recycled correctly in order to stay out of landfills and, by extension, the ecosystem and our bodies. Here are some examples of harzardous materials in a typical PC.

The Toxic Brew Inside Your Computer

Toxin Component Problem
Lead Monitor Toxic to the kidneys and nervous and reproductive systems. Inhibits mental development in children and fetuses.
Barium Monitor Can cause brain swelling, muscle weakness, and damage to the heart, live and spleen.
Hexavalent chromium Case Can cause DNA damage and bronchitis.
Berylium Motherboard Can cause cancer.
Mercury Flat-panel displays Can cause brain and kidney damage.
Cadmium Semiconductors, plastics Can cause kidney and bone damage.
Brominated flame retardants Plastics Can be harmful to developing fetuses.

How to Avoid Sham Recyclers

Recycling your old computer is the environmentally right thing to do, but if you do it the wrong way, all your good intentions amount to nothing. That’s why it’s imperative to avoid bogus recyclers who promise to take all the right actions-separate toxic components, keep plastic and metal out of landfills, avoid exporting anything-but then do none of them, instead stripping out valuable metals and selling everything else to junk dealers.

These dealers export e-waste to impoverished areas of Africa or Asia, the world’s dumping ground for toxic electronic waste, where laborers, including children, work knee – deep in toxic materials for pennies a day as they strip the junk down to its component parts. According to the Computer TakeBack Campaign, an electronics recycling watchdog group, Americans export the equivalent of 5,126 shipping containers of e-waste every year. Even here at home, prison inmates sometimes do the same kind of work without proper health safeguards.

So whom can you trust? Visit the Computer TakeBack Campaign’s site, which maintains an interactive US map to help you find ethical recyclers in your home state. The list was created in conjunction with the Basel Action Network, the best-known worldwide advocacy group for the end of e-waste trafficking. It promotes an “Electronics Recycler’s Pledge of True Stewardship,” a vow to behave responsibly that recyclers can sign to get onto BAN’s list (it currently has fewer than 70 signatories in just 30 states).

How to Wipe Your Hard Drive Clean

No matter which disposal option you choose, be sure to wipe your hard drive clean before you do anything. Your drive knows a lot about you, and anyone who gets their hands on it can learn a lot about you, too. Dragging all your files to the recycle bin isn’t nearly enough to erase your presence from the drive-the only thing it does is tell your computer it’s OK to overwrite those files. The files still exist, however, and someone with a little technical expertise and a disk utility can recover them. Even reformatting your drive doesn’t quite do the job. Reformatting erases file addresses, but the files themselves can still be present, albeit invisible to normal directory searches. Before your computer leaves your home, give it a full-on lobotomy, even if it’s destined for a landfill or a recycling center that will tear it to pieces.

To truly wipe your hard drive clean, you have to write meaningless data to it over and over again. Think of it as painting coat after coat of paint on a wall until you can no longer see the colors underneath. The US Defense Department maintains a security standard of six rewrites to wipe a disk, so software programs designed to wipe your disk will typically do that or more.

You can choose from many free utilities to wipe your drive clean, such as Eraser 5.86 or Darik’s Boot and Nuke. CNET has a list of free drive-wipers here.

If you own Norton’s SystemWorks, you’ll find a drive-scrubbing program in it called Wipe Info. Another popular option is the $39.95 DiskDeleter Pro (a free trial is available here).

Of course, there’s always the doomsday option-a hammer. Open up your computer, unscrew the hard drive from the chassis (it’s not always easy), and demolish it. While that’s the ultimate in data security-and, perhaps, satisfaction-it’s not necessarily the best thing to do, since you’re wasting a usable drive that could potentially find a home in a school or charity.

Get a Tax Break on Your Equipment

Can you take a tax deduction on your donation of an old computer? Absolutely. For individual donors like you, the charitable deduction for contributions of technology products is their current fair-market value. As you may know, however, computer equipment loses its resale value quickly, so the older your computer is, the less you can claim. Ask the organization to which you donate your computer to estimate its current value and give you the appropriate paperwork: you need a written receipt for your tax return. And a bit more good news: you can deduct the shipping costs you incur in donating your PC, again, as long as you keep the receipt.

Fifteen Simple Ways to Green Your Data Center on the Cheap

Fifteen Simple Ways to Green Your Data Center on the Cheap

  

There’s been a lot of talk lately about green data centers, and with good reason. As businesses move away from paper records and in-person transactions and more towards computer-based transactions and digital information storage, the amount of energy that data centers use is growing — and fast.

According to the EPA, data center energy use doubled between 2000 and 2006, and many are worried this figure may double again in just a few years. With energy prices on the rise, smart IT and facility managers and even top executives are taking a look at ways to build and maintain not only effective, but efficient data centers.

The good news is that you don’t have to spend big money to reap big energy savings. And while a few high-profile efforts have been launched recently that require significant capital outlays to be successful, there are a number of simple yet effective ways to “green” a data center, techniques that are kind to budgets and easy to implement.

Some simple ideas work best with new facilities, while others are better suited to retrofits of existing data centers, but the truth is, all will work well to cut energy use, and yield financial savings, while not compromising reliability.

If your company is planning to build a new data center — and many companies are — it pays to build energy efficiency into your plans. Here are eight fairly easy ideas and technologies for new data centers that you should think about:

1. Air-side economizers not just for the office anymore. A bit like opening a window on a cool day, an air-side economizer takes advantage of cooler outside air to cool the inside of your data center. At the very least, they require much less energy than typical HVAC systems, and often provide free cooling. In the past, data centers avoided the use of air-side economizers because of a belief in the need to maintain tight humidity and temperature controls. The technology has traditionally been very common in many office settings, but today companies like Intel prove that servers are much more durable than previously believed. As a result, air-side economizers are installed more often. The best news? Paybacks can be enormous. A company’s data center could see as much as a 60 or 70 percent reduction in cooling bills compared to those of typical data centers.

2. Centralize your air handling. One simple solution for energy savings is to place your HVAC equipment and your economizers on the roof, or in a separate room on an exterior wall, rather than inside your building. When your equipment is outside the space, it’s easier to reach and maintain than when it’s inside, and it runs much more efficiently.

3. Practice good airflow management. Almost everyone knows that servers require cool air at the front and discharge heated air at the back. And yet ensuring that hot and cold air don’t mix in the wrong places still isn’t top of mind when designing data centers or deploying servers into the room. Ensuring that cool air goes where you need it (and that hot air doesn’t) is as simple as installing “blanking panels” within server cabinets to block the short-circuiting of hot air. You should also put servers back-to-back and front-to-front in a “hot and cold aisle” arrangement. You can even install hot aisle barriers (hot aisle containment) — similar to the plastic sheeting you see in supermarket cold cases — to contain heat at the end of the hot rows and above the cabinets.

4. Roll with a heat wheel. A heat wheel is a type of heat exchanger designed as a big aluminum wheel that both absorbs heat and transfers it from the inside to the outside without introducing outside air into the facility. This provides the same kind of cooling as an air-side economizer, but without the addition of outside air.

5. Change your supply air temperature. Most data centers run at temperatures much cooler than necessary. While typical operating temperatures are usually about 56 to 60 degrees Fahrenheit, recent tests by Intel, Sun Microsystems and NetApp have shown that servers can tolerate much higher temperatures as well as higher humidity. If you are using good airflow management in your data center, you can stop worrying about keeping the air conditioned to 56 degrees, and start saving energy and money.

6. Build what you need. Building a modular and scalable infrastructure based upon a logical and consistent power and cooling module will allow the facility to purchase only what is required for its initial computing needs while allowing seamless upgrades and additions as more computing power or space are needed.

7. Monitor, monitor, monitor. Monitor critical load and mechanical power, water consumption, gas consumption, and even waste water. Direct Digital Control (DDC) systems are becoming more common and have the innate ability to monitor and trend anything. As a result, it is simple today to see what is going on within the facility and project usage into the future. In addition, it provides more immediate feedback on implementation of energy saving measures or operational changes.

8. Ask: What is my carbon footprint? Nearly all pundits agree there will be some form of carbon regulation in the future. Knowing your carbon footprint will allow the data center manager or CIO to make informed decisions on data center operations and usage looking toward the future.

If you are in charge of an existing data center and looking for simple ways to start saving energy and money without a major remodel, we recommend a few ideas to get you started:

1. Keep the hot and cold air separate. Data center servers generate heat but need cool air to run well. Yet it’s surprising how few data center managers have thought about keeping the hot air separate from the cold air. Many facilities are still designed so that the hot air from the back of a server is blowing into the front of another server. This creates a need for brute force air conditioning throughout the data center and often supplemental fans sitting on the floor, which both use massive amounts of energy very inefficiently. By configuring servers to prevent hot and cold air from mixing — either through the use of hot and cold aisle barriers or by placing servers back- to-back and front-to-front throughout the data center — the amount of cool air drops dramatically throughout the facility.

2. Airflow management is key. Again, rather than worrying about overall temperatures in a data center, the key to running one efficiently is to think about the microclimates created by servers throughout. Considering how air flows and is heated by servers allows you to see where to implement low-cost solutions. For example, blanking panels in server cabinets to stop hot air from short-circuiting through the cabinet, or “hot and cold aisle barriers,” which are essentially plastic sheets hung from above that reduce the mixing of hot and cold air. Another option: On a raised-floor computer room cooling unit ,you can install return-air duct extensions that direct the warmer air out through the ceiling. This is a fairly simple change that will generate great energy savings payback and reduce hot spots.

3. Manage energy in addition to reliability and uptime. Data center managers have traditionally monitored only server reliability and consistency. Yet in today’s high-energy business environment, you don’t have to sacrifice energy savings for reliability. Many local utilities offer incentive programs, in essence paying business customers for energy saved. For example, California utility PG & E pays its large customers 14 cents per kilowatt hour saved.

4. Make sure equipment is running correctly. It’s common to find separate data center cooling units set so that one humidifier is providing moist air while the other is dehumidifying, causing both to work harder than they should. The solution? Check temperature and humidity controls on HVAC equipment regularly to ensure that all are working properly and efficiently.

5. If you aren’t using it, turn it off. Idle servers often are kept running even if they are not used. Just like your lights at home, turning idle servers off is easy and provides an immediate energy and cost savings. Similarly for cooling units, if the extra capacity isn’t needed, then consider turning the unit off.

6. Install VFDs on computer room cooling units. Chilled water units typically can be operated at lower air flows because there is spare capacity. The fan energy savings can be enormous with variable speed drives (VFD) operating at partial speed. This goes very well with improved air flow management solutions.

7. It’s a virtual world. Grid computing using current server hardware or blade server technology provides a tremendous opportunity to “tune” the computing environment to the computing requirement and as a result can reduce the power consumption for servers and air conditioners.

Finally, whether you are building a new data center or trying to ‘green’ an existing one, there are a few overall management changes to keep in mind if you really want to reduce energy use. First, set targets for energy use company-wide and allocate operating costs based on those targets. By making internal departments aware of energy use — and by sharing targets and actual usage figures with the entire company — you make saving energy part of the corporate mindset from top to bottom.

Second, bridge the disconnect between IT and the facilities department. In most companies, these two departments don’t talk much and they certainly don’t jointly plan how to save energy. They should.

Most importantly, recognize that energy is an increasingly expensive part of running your business. And, it’s one of the few costs you can control just by managing energy use efficiently. Once you recognize that actively managing energy is as important as any other key business function, you are on your way to a healthier bottom line.

Green Energy Summit 2009

Program Unveiled for Green Energy Summit 2009

The first of its kind in India, Green Energy Summit 2009 will provide a unique platform for debate, dialogue and action between research, industry, academia, financial organisations, entrepreneurs and government bodies worldwide. The four tiers of the summit will see a congregation of the most intelligent minds and proactive organisations to create a sustained, result-oriented mindset, bringing into picture those questions that are most relevant for India at this juncture. 

From March 4-6, world leaders in the renewable, green, clean technology and energy efficiency sectors will gather in Bangalore for Green Energy Summit 2009. The summit is a highly efficient forum for varied stakeholders from solar, wind, biomass, IT, transport, construction, aviation, nanotechnology and biotechnology to bring together the business and science of the most important and relevant Green Energy and Clean technologies ( http://www.greenenergysummit.com ).

Green Energy Summit has two objectives, amidst a vast array of highly complex issues. First, to bring to a single, public platform – stakeholders and decision-makers from policy, finance, manufacturing and trade. Second, to help catalyze solutions, initiatives and opportunities, so that Green Business, and therefore the necessary change we seek so desperately, can prosper.

“While the business opportunities in the future are enormous, we understand the need for businesses today to gain a foothold so that economically viable change can be more logical, active and urgent. To facilitate this, we will be bringing together those who are creating, propagating and establishing the systems and standards that are needed, so there can be a firm stimulus for action that goes far beyond the rhetoric, with practicable initiatives being addressed,” says Dilip Thomas Steering Committee Member/Program Chair & CEO of Saltmarch Media, the organizers of Green Energy Summit ( http://www.greenenergysummit.com/ )

“Green Energy Summit is unique in that it endeavours to identify practical steps that will be of interest to decision makers in govt, business, industry and civil society in order to move the agenda forward with speed and urgency,” adds Dr. J Gururaja, Former Sr. Advisor to United Nations. Among the participants expected to explore a sustainable future at GES are the sector’s leading financiers, entrepreneurs, corporations, scientists, policy-makers, city planners and the buyers and sellers.

The first announcement of the complete program has been published from the summit website ( http://greenenergysummit.com/programOverview.html ). Featured speakers include the finest group of ‘faculty’ ever assembled on this subject:

3 Ways To Go Green With Your Computing Habits

3 Ways To Go Green With Your Computing Habits

If you are also someone like who wants to save this Earth and contribute in whatever small ways to make this world a Greener, Happier and Lively place to live, this article will help you give a thought to your daily computing habits in order to contribute to a Greener Earth. Also, adopting these habits, can help you save lot of cash in today’s gloomy market condition.

1.) Print, But With Care

If you are someone who usually takes lots of prints everyday, this is something that you should think about. Are you unnecessarily printing Emails just because you find it good to read on a paper than on a laptop screen? If yes, this is the first computing habit you need to look at. Print, but with care. The paper you print on, comes from the trees. More prints in turn means more need for paper, which clearly will lead to lesser trees. Less tress is simply less Green.

You can also contribute to a Greener Earth, by changing your Printing Preferences. Windows by defaults, prints single page on a single sheet. If your need allows, you can change this setting to print 2 pages ( i wont advice more) on a single sheet. Also, if your printer can handle it, make it a duplex job. If you cannot print 2 pages on a single sheet, try reducing the size of the font. This ways, atleast you will help by saving on Ink.

Changing your Printing Preferences can help save a lot of paper

Printing with care is one of the most easiest way of contributing to a Greener World. If you have colleagues who do the same, you can help educate them by adding a few lines like

Please consider before you print this email. Printing an email consumes paper which comes from Trees. Help conserve the nature by saving on the paper.

2.) Are you consuming too much Power?

This is another tip which can help you save on Power Consumption. Windows can automatically switch off your Laptop or Desktop after a certain idle time. You can configure this by going to the Control Panel and then selecting the Power Options. 

Optimizing Power Options of your computer can help save Power.

If you often go-away for meetings or leave your computer unattended, you can possibly configure your system to turn off your monitor, hard disk and go on a stand-by after a certain idle time. You might also be interested in learning about Saving on your iPod Power and Getting more from your Mobile Battery.

3.) Turn Off When Done

If you are done with your computing needs, do remember to switch off your monitor, printers, scanners etc. Even though you might find it hard to switch it off and then switch it on everytime, believe me, this is something that can contribute to the green earth. Even if your computer is on a low power mode, it still draws power. 

You might even consider switching off the charging units for your camera, mobiles, batteries etc as soon as they are done.

What are the other ways by which one can contribute towards a Greener Earth? Do mention them in comments and i shall update the post with backlinks.

IT leaders share green-tech predictions for 2009

IT leaders share green-tech predictions for 2009

With the down economy and shift in the political climate, experts foresee green IT gaining momentum in ‘09

It’s that time of year again to dust of the old crystal ball and put forth some predictions as to what 2009 holds for the world of green technology. Rather than leaving the speculation to myself, however, I once again decided to tap experts at a host of organizations on how they envision green IT evolving in the year to come.

Suffice to say that no one has dismissed the green-tech movement as a mere passing fad. Both economic and political conditions (e.g. President-Elect Obama’s vision of a cleaner energy economy) will continue to drive vendors to develop greener wares and organizations across the board to embrace greener practices — be it in the name of cutting costs, meeting environmental regulations, or simply “doing the right thing.”

Green-tech predictions for 2009 follow:

 

robaldrich.jpgRobert Aldrich, director of datacenter solutions, Cisco

1. Green in the U.S. market related to IT will be replaced by more concise, definable concepts in the mainstream media, such as energy equivalents.
2. The first generation of IP-based energy management applications will be released from many major IT vendors.
3. IT’s consumption profiles will start to be measured under new criteria with teleworking and cloud computing as the next “killer apps” (today’s killer app: virtualization).
In summary, I would say that 2009 will see the emergence on a number of sleeper “greenies” who have been doing their homework diligently over the last two years. I firmly believe that many in IT want to do the right thing (in this case, the “right thing” meaning the altruistic thing) but simply lack the time and monetary incentive to do so. The issue is not so much the IT professional per se but the system by which our roles are incentivized.
I think 2009 will be about what I would call Green IT 1.0, and that is “What does Green IT mean to me? What can I do individually, professionally, above and beyond recycling at home, to feel like I’m part of the solution?” In a word, internalization and the realization that a “green” lifestyle is a choice and involves a series of educated trade-offs.
Conversely, a sound focus in a down market is to trim operating expenditure through incremental improvements to infrastructure and operations. With commercial energy market volatility, popular opinion, and geopolitical considerations at hand, the time to examine a sound energy strategy is now.
 

Subodh_Bapat.jpgSubodh Bapat, vice president and distinguished engineer, Sun Microsystems

1. Energy efficiency to reduce watts per compute workload will continue to be a priority in 2009, given high ROI and overall energy limitations.
2. Datacenter blueprints will continue to evolve with aggressive virtualization saving potentially between two and ten times the savings of facility efficiency measures.
3. Power management will be used to throttle down servers (and other IT equipment) when not in use, something not done effectively today.
4. High-temperature datacenters, some without any mechanical cooling systems, will be discussed more in 2009 (but very few will be implemented).
5. Collaboration will continue to drive progress forward through new standards (The Green Grid), best practices, and open tools (OpenEco.org) as we scramble to meet energy and climate goals. Sun will continue to innovate on eco in hardware (servers and network), software (including efficient coding), services (datacenter design), and partnerships.
 

lewis_curtis.jpgLewis Curtis, infrastructure architect and advisor, Microsoft

1. 2009 and 2010 will see the start of IT organizations investigating environmental regulation strategies and increase environmental impact skill sets. Even if IT leaders don’t care about environmental stewardship, they care about government regulations that impact IT operations. With the new presidential administration committing the United States to a environmental cap and trade model, the European Union promoting a datacenter code of conduct, and various government bodies promoting more oversight and environmental and energy ceilings, IT leaders will need to quickly become more cognizant with environmental regulations and work to form productive, environmentally sustainable strategies for their organizations.
2. In 2009, the economic downturn will greatly impact green IT investments. There is no doubt that organizations are reducing IT investments in light of the economic downturn. Many have argued that the reduced price of oil and economic pressures will kill the green movement. The death of the green movement in organizations and society has been greatly exaggerated. However, there will be some changes in green IT investment activity.
Environmental sustainability projects that positively impact the bottom line in the short run will be moved to the front of the line. Examples include virtualization and consolidation projects.
Environmental sustainability projects that increase costs of organizations or do not impact immediate regulatory needs will be delayed. For example, some recycling efforts (paper, e-waste projects) will probably not expand as much as originally anticipated in 2009.
3. 2009 will be the year of the green developer. Besides all of the “green is good for IT” articles, there has been a good deal of writing about building green physical datacenters as well as adopting virtualization. However, when analyzing different professionals in the IT market, developers were usually the most passionate about environmental impact. Yet, developers have the least amount of guidance on environmentally sustainable development best practices.
What are best practices to reduce energy and computational resource consumption for application design?
Sloppy code is wasteful. Not only is it slow, error prone, and often not extensible, it usually wastes energy and utilizes unnecessary computational resources. This has a significantly negative impact on the environment. However, most architects are given the “virtualize the problem away” answer for environmental sustainability.
4. In 2009, competition will increase for the green cloud. Who is the greenest cloud provider for your applications and solutions? Which cloud providers will report environmental metrics and provide concrete green operational level agreements for enterprises which you can use for verification in your own environmental reporting? Currently, we don’t know how cloud providers will compete with green services. However, by the end of 2009, I predict we’ll start finding out some answers.
 

albert_esser.jpgDr. Albert Esser, vice president of datacenter infrastructure, Dell

In 2009, energy efficiency in the datacenter will continue to be a big focus for IT departments. Not only will improvements in overall energy consumption help reduce power and cooling costs, but applying green practices in the datacenter can also unlock hidden assets — space and compute power — and extend the lives of their datacenters well past 2009. Here are five things that IT managers should consider in ‘09:
1. Industry standards: By not locking oneself into a proprietary solution, datacenter managers can stay up-to-date on improved designs on efficiency. Leveraging industry standards allows businesses to upgrade existing systems and swap out old ones for more efficient models with ease.
2. Productivity: By looking at the big picture in terms of productivity, managers will have a better sense of what levers they can play with beyond one specific area, allowing for better management of power consumption.
3. Virtualization: Though virtualization remains one of the hottest topics, the amount of server utilization has decreased over the years. This needs to change. Businesses can significantly boost productivity and energy efficiency by increasing the number of servers being virtualized.
4. Smart cooling: One of the biggest impacts on the environment is the use of cooling in the datacenter that can be overcome by moving cooling closer to the rack, understanding where hot spots are, and utilizing air economizers that use outside air to keep servers cool.
5. IT productivity: While improving energy efficiency through power and cooling methods offers significant returns, businesses can also optimize datacenter performance by focusing on IT productivity. The greening of the datacenter can be accomplished by ensuring servers are optimally utilized in order to reduce the amount of unnecessary power being consumed.
 

stevesams.jpgSteve Sams, vice president of site and facilities services, IBM Global Technology Services

This coming year, economic and budgetary concerns will impact the datacenter. With less money available, it’s important that organizations get the most bang for the buck with their IT facilities and resources. By considering all options available in the software, hardware, and the virtualization realm, IT managers can run the most cost-effective, energy efficient datacenter possible.
Three things that an organization must look at during these troubled economic times are: Extending the life of their datacenter — numerous opportunities exist throughout the datacenter to do more with less, rationalizing end-to-end datacenter infrastructure, and utilizing modular/scalable approaches when building a new datacenter. IBM is shifting from a custom to standard datacenter design business to apply these cost-cutting tools. In 2009, we will continue to see innovative implementations that will have larger impacts on an organization’s bottom line results.
 

ted_samson.jpgTed Samson, senior analyst, InfoWorld

1. PC vendors will continue to compete to purge their new wares of toxic chemicals, such as polyvinyl chloride and brominated flame retardant. Moreover, they will release systems that meet or exceed the forthcoming Energy Star 5.0 standard before it officially goes into effect.
2. In the name of cutting energy costs, more IT shops will take the calculated risk of powering off at least some servers when they’re not in use.
3. Adoption of PC power management software — one of the lowest-hanging green-tech fruits — will increase in 2009, saving companies as much as $75 per PC per year.
4. Vendors will roll out more products drawing on sensors that will measure such attributes as power consumption, temperature, humidity, and utilization. The purpose is to give datacenter operators a real-time picture of how efficiently their facility is operating at any point in time and to help locate hot spots and other areas of inefficiency.
5. More new datacenters will be built to comply with LEED (Leadership in Energy and Environmental Design) standards in an effort to boost energy efficiency and earn green bragging rights.
6. More companies will start to scrutinize the inefficiency of their supply chains and, using smart tech, will find ways to streamline operations and cut expenses, including fuel and packaging costs.
 

willswope.bmpWill Swope, vice president and general manager, Corporate Sustainability Group, Intel

Economic conditions today are complex enough that companies can no longer just talk the talk; they need to walk the walk in order to save resources in 2009 and beyond. The financial turmoil will certainly put additional pressure on these decisions but, when done correctly, sustainability is creating savings not adding expenses.
There will be real pressure on IT to reduce operating costs, much of which will be achieved by implementing projects such as more efficient datacenters. We also expect to see more computing resources used to improve efficiency of all aspects of a company’s operations. Computers, and computing, are fundamental to increasing efficiency in most every area that consumes carbon.
The aggregate electronics industry will face an eventual growth hurdle if we can’t come to an agreement on an industry-wide approach to dealing with e-waste. E-waste is one of the unintended consequences of the amazing innovation in our industry. The issue becomes more complex as the availability of new device capabilities and categories emerge. Beyond removing toxins from consumer electronics materials, we need to quickly come up with a solution that mitigates dumping overseas and encourages reuse and recycling.
Industry leaders and government officials will determine which stimulus plans have far-reaching, positive impacts on reducing carbon footprints. We believe this objective is imperative to keep moving forward, but we also need to define long-term, systemic changes to many of the “assumed rights” regarding how we, as individuals, consume resources today. Reform in this regard along with the stimulus packages will in effect help enact real change for a better environment.
 

RogerTipley.jpgRoger Tipley, director, The Green Grid

The incoming presidential administration is expected to bring a renewed commitment to addressing energy management, leading the U.S. government to increased collaborative efforts with industry organizations that are dedicated to advancing energy efficiency and cost savings in datacenters throughout the nation. Building upon existing energy policies, The Green Grid expects government agencies, such as the U.S. Department of Energy and Environmental Protection Agency, will work even more collaboratively with industry organizations to develop more effective ways to improve energy efficiency in datacenters. This sustained, shared effort between government and industry designed to improve U.S. datacenter efficiency in 2009 will also have global implications in the years to come.
 

Vertal.jpgLarry Vertal, senior strategist, AMD

This coming year, U.S.-based corporate IT managers will start getting the first indications of another budget to deal with sooner rather than later: Their carbon budget.
Corporate management will start to see carbon accountability waterfall down into their planning in anticipation of the impact of federal and state legislation and regulations.
California organizations, along with those in other western states, are beginning to define what the AB32-mandated carbon cap-and-trade program means for their businesses. These companies would acquire annual allowances to emit a certain amount of CO2 and other GHG (greenhouse gas) emissions based on specified criteria. They would then have three options: 1) emit the amount of GHG emissions allowed by their permit or allowances, 2) reduce their own GHG emissions and sell excess allowances to other emitters, or 3) emit more GHG emissions by purchasing unused permits or allowances from another emitter.
President-elect Barack Obama reaffirmed his commitment to adopting a cap-and-trade carbon program as part of his national climate change policy shortly after the election. He went on to say the United States must reduce carbon dioxide emissions 80 percent by 2050 — which is in line with proposals by the U.N.’s Intergovernmental Panel on Climate Change.
The good news for IT and facilities management is that the major factor in their own carbon budgets will be driven by electricity consumption. Over the last few years, many IT and datacenter operations have focused on getting an integrated view of and optimizing their energy consumption, which will become the foundation for managing carbon budgets. The challenging part will be the extent to which such carbon accounting may expand to include taking into account what is often called embedded-energy, and hence the embedded-carbon-footprint of equipment purchased.
Stay tuned, IT, it could be a wild ride.

Doug Washburn, analyst, Infrastructure and Operations, Forrester Research

1. Expect the PC environment to steal much of the green IT spotlight away from the datacenter. Why? While the datacenter is often a first target on organizations’ green IT hit list, recent data reveals that the distributed PC environment is likely to be consuming more than the datacenter. With that in mind, expect IT ops professionals to aggressively pursue PC power management best practices and invest in software to assist (e.g. 1E’s NightWatchman, BigFix Power Management, Verdiem’s Surveyor). Beyond the reduction in CO2 emissions, the financial savings can add up: General Electric and Dell boast savings of $2.5 million and $1.8 million per year, respectively.
2. Expect the traditional definition of green IT to be refined. Today’s green IT primarily focuses on the “greening” of IT itself — such as sourcing Energy Star PCs or virtualizing servers. While the traditional view of green IT will become pervasive, the positive environmental — and financial benefits — of IT as enabler of the “Green Enterprise” will be much more profound than IT just greening its datacenter or PCs. With that in mind, tomorrow’s green IT will be defined much more broadly to position technology as an enabler of the “Green Enterprise.” Early examples of this include Nike’s “Considered Index” desktop application which empowers designers to make more eco-friendly decisions when making shoes, and UPS’s “package flow” software to eliminate left-hand turns from delivery routes which saved $8.4 million in fuel costs and 32,000 metric tons of CO2 emissions in 2007.
What do you predict will happen in the realm of green tech in 2009?

Green computing tips- environmentally friendly computing tips

Green computing tips- environmentally friendly computing tips

Green Computing Tips for Printers

When sourcing printers for your organisation try to be consistent. If you have ten different black and white laser printers that are all different makes and models, then not only will it prove more difficult to fix technical problems, you will be unable to reuse parts from your broken printers. However, if you have 10 laser printers all of the same make and model, when one becomes damaged, you can cannibalise the parts and use them as spares for your printers rather than having to dispose of the printer completely. If you outsource your technical support this could also reduce the number of points-of-contact necessary.

Green Computing Tips for Recycled Toner

In our experience recycled toner is anything but environmentally friendly or cheap. Looking at a face value price comparison between new toner cartridges and recycled toner cartridges, it may seem like you have got a good deal and a reasonable cost-saving. However, much recycled toner is highly prone to leakage, which means that you will need to replace your toner much more regularly, and that lots of paper will be wasted when the toner leaks. It will also probably cost you more in technical support, repeatedly having to have your laser printers cleaned out, and it will also cost you more money in replacement parts as recycled toner tends to be abrasive and to cause damage to laser printer fuser units.

Recent research conducted by the University of Queensland has also suggested that toner particles are highly carcinogenic and cause cancer. If your toner leaks more of it will be in the air and it is reasonable to assume that the risk is increased. See, for instance, this BBC report on the association between laser printers and cancer:
http://news.bbc.co.uk/1/hi/world/asia-pacific/6923915.stm

Replace your RAM

Before consigning older spec machines to obsolescence, try upgrading the RAM. When older computers are performing slowly it is often only the RAM than needs upgrading. You can also try removing applications that are taking up uneccessary amounts of memory, or prevent them from starting up on boot by using msconfig:

Start > Run > type “msconfig” > enter

Now go to the Startup tab and disable anything that you don’t need

Green Computing Tips for Monitors

Need to invest in larger CRT monitors or TFT screens?

Before investing in larger CRT or TFT monitors try using the F11 key in Internet Explorer or Mozilla Firefox, and see if this helps to solve your screen size issues. The F11 function key gives you a full screen view which may give you as much as an extra inch and a half of screen space. Simply hit F11 again to return to the normal view.

Green computing Tips for Computer Hardware Rollouts

If you are planning a new hardware rollout, then timing and planning is key to make sure that you do not fall victim to deploying outmoded or highly depreciated kit. If a hardware vendor approaches you with an ostensibly great buy-now deal, then you need to consider the following:

  1. Are we ready to deploy our hardware?
  2. Will the hardware need to go into storage until we are ready to deploy and how much will it cost?
  3. How much will the hardware have depreciated before we are ready to deploy it?
  4. Is the hardware likely to be outdated by the time we are ready to deploy it, and how much will this shorten its lifespan of operable usefulness.

Asset Manage your Computer Hardware

Keeping track of your computer hardware and knowing exactly what computer assets you have in your business is one of the best ways you have of avoiding hardware wastage. Spare computer hard drives, disc drives, RAM and much else can be kept and re-used as needed rather than needing always to buy new. If you keep a good inventory of your stock you will find that your bottomline spend can be reduced and the amount of your hardware finding its way into landfill can be reduced.

Switch off your Computers Overnight

Save on your energy bills and reduce your carbon footprint: Don’t leave computers on standby, switch them off when you are not using them, overnight at weekends and during long breaks. You should also consider making it company policy to switch off monitors and leave computers on standby or in hibernation when end-users are away from their desks for a long time during the day. Boot times these days are often fast enough to justify this and to make a big energy saving here. You should also think about making someone responsible for switching off printers overnight.

Save and Go Green: Computer Energy Saving

Save and Go Green: Computer Energy Saving


A few months ago, after discussing ways to save energy with some people at work, a co-worker said that he unplugs his computer at night to save on energy. I had never thought of just simply unplugging your computer to save additional energy. This is probably a pretty common question most people would like to know, but don’t really know the true answer to. I wasn’t totally sure myself so I looked into how much energy do our computers use and ways to save money on cutting their energy usage.
Saving Computer Energy

Computer Energy Use

I never realized that computer use as much energy as they do, especially desktop computers. PCs alone can consume anywhere from 50 – 250 watts of energy!!! The monitor itself also consumes tons of energy, with a traditional CRT monitor consuming more than newer LCD monitors. Laptops on the other hand use far less energy at around 45 watts and are way more energy efficient than your average desktop computer. In order to get a better idea of how much it would cost to run your computer, I crunched some numbers and determined how much it would cost to run.

I first want to preface the numbers I calculated with some basic definitions and assumptions I made. I found a great definition on Wikipedia that sums up how a kilowatt-hour is calculated:

If a 100 watt light bulb is turned on for one hour, the energy used is 100 watt-hours or 0.1 kilowatt-hour

Most energy companies charge customers on a kilowatt-hour basis, making it an important number in my calculations. There are several assumptions I will be making throughout the rest of this article used for my calculations:

  • The computer is in use for 2 hours a day for 7 days a week.
  • Each value displayed is in kilowatt-hours, unless specified with a dollar sign.
  • The cost of electricity is $0.12 per kilowatt-hour.

 

24/7 Computer Energy Usage

  Watts Used Day Week Month Year Year Cost
Desktop Computer 120 2.88 20.22 87.6 1051.2 $126.14
Laptop 45 1.13 7.9 34.22 410.63 $49.28
Old CRT Monitor 80 1.92 13.48 58.4 700.8 $84.10
LCD Monitor 35 0.84 5.9 25.55 306.6 $36.79

 

As you can see from the above table, a desktop computer with a LCD monitor running 24/7 can cost you over $160 per year. That’s a huge number considering most desktop computers can cost as little as double that amount. This not only has a major affect on your wallet, but also has a huge impact on the environment. There is no need to waste that much energy when the average person only uses their home computer a few hours a day.

Let’s see how much you can save by simply setting the sleep or standby functionality on your computer.

 

Energy Saving: Sleeping Computer

  Watts Used Day Week Month Year Year Cost Year Savings
Sleeping Computer 6 0.37 2.61 11.32 135.78 $16.29 $109.85
Sleeping Laptop 1 0.11 0.79 3.41 40.88 $4.91 $44.37
Sleeping CRT Monitor 5 0.27 1.9 8.21 98.55 $11.83 $72.27
Sleeping LCD Monitor 3 0.14 0.95 4.14 49.64 $5.96 $30.84

 

By simply turning the sleep functionality on your computer and monitor, that $160 above goes down to only $20 per year.

Setting the sleep functionality on your computer is a great idea, but should only be used if you forget to turn off your computer. The best way to really save money on computer energy use is to turn off and unplug your computer when not in use. Even if you turn your computer off or allow it to sleep, it still is using a slight amount of energy. Though the energy difference is small, it can really add up if you allow your computer to sleep instead of turning it off.

 

Energy Saving: Turning Off/Unplugging Computer

  Watts Used Day Week Month Year Year Cost Year Savings
Turned Off Computer 3 0.31 2.15 9.31 111.69 $13.40 $112.74
Unplugged Computer 0 0.24 1.68 7.3 87.6 $10.51 $115.63
Unplugged Laptop 0 0.09 0.63 2.74 32.85 $3.94 $45.33
Unplugged CRT Monitor 0 0.16 1.12 4.87 58.4 $7.01 $77.09
Unplugged LCD Monitor 0 0.07 0.49 2.13 25.55 $3.07 $33.73

 

You can save even more money by unplugging your computer whenever you are not using it. Not just that, you will be using less than 1/10th of the amount of energy that you would be using if you keep your computer running at all times.

Save Energy on Computer Accessories

You can save additional energy on top of what you can save on your computer. Think about all the accessories you can have for you computer. Most people have common accessories like printers, modems, routers, speakers and many others. The table below shows the cost to run various computer accessories.

 

24/7 Computer Accessory Energy Usage

  Watts Used Day Week Month Year Year Cost
Home Inkjet Printer 50 0.15 1.02 4.44 53.29 $6.39
Home Multi-function Printer 30 0.32 2.23 9.64 115.71 $13.89
Cable Modem 9 0.22 1.52 6.57 78.84 $9.46
Router 5 0.12 0.84 3.65 43.8 $5.26

 

The printer is one of the larger energy users of of all computer accessories. All-in-one printers in particular use much more energy than traditional printers because they have much more functionality. Many accessories including your router and modem are not able to go into standby and therefore are running at all times. Even though they use far less energy that a computer, it still makes a difference to turn them off or unplug them when you are not using them.

 

Energy Saving: Computer Accessories

  Day Week Month Year Year Cost Year Savings
Home Inkjet Printer 0.05 0.35 1.52 18.25 $2.19 $4.20
Home Multi-function Printer 0.08 0.54 2.34 28.11 $3.37 $10.51
Cable Modem 0.02 0.13 0.55 6.57 $0.79 $3.77
Router 0.01 0.07 0.3 3.65 $0.44 $9.02
             

 

Easy Ways to Save

One very easy way to save money is to ensure that you set the sleep functionality on your computer. This can be easily done on a Windows machine by:

  1. Under the Start Menu go to your Control Panel.
  2. Under the Control Panel, click on Power Options.
  3. Click on the Power Schemes tab to be able to set all of your power settings.

Under the tab I described above, you can set the amount of time your computer is inactive before it will go into standby ( or sleep ). You monitor can also automatically be turned off through this menu as well. Sorry to Mac and Linux users, but it should be pretty simple to find out how to set these settings on your machine.

One extremely easy way to make sure you computer and its accessories are all turned off is to use a power cord. I have my computer, monitor and any accessories plugged into one power cord. When I am completely finished using my computer, I simply switch off the entire strip. It’s really that simple and it makes it extremely easy to ensure that computer and its accessories are using absolutely no power.

If you are in need have to use a computer all the time, you could try using a laptop instead of a traditional desktop and monitor combination. Not only does the laptop use 1/3 of the energy, but they are much more portable and takes up less room. It can be hard to use a laptop all the time, so you could also look into buying a more energy efficient computer. Many of these computers use the same amount of energy as a laptop, but are as powerful as a traditional desktop computer.

Energy Saving Tips For Educational Institutes

Energy Saving Tips

Students, faculty and staff can help the energy conservation effort by following these tips:

Computers:
Screen savers do not save energy but giving your computer a nap does. Enable power management features so your computer monitor and hard drive will go into a low power (blank screen) “sleep mode” when not actively 8in use.

Keep all computer equipment off unless in use – especially at night and on weekends.

Copiers & Printers:
Enable power management features on laser printers and/or turn off laser printers when not actively printing.

Think before you print! Print and copy as little as possible.
When you must print, do it double-sided.
Edit on screen, not on paper.
Save to disk instead of printing on paper.
Use e-mail to minimize paper use and don’t routinely print e-mails.
Send and store documents electronically instead of on paper.
Designate a box for scrap paper and use it for printing all drafts or unofficial documents.
Circulate documents instead of making an individual copy for everyone.
Reuse envelopes by placing a new label over the old address.

Lights:

Turn off unused or unneeded lights.
Use natural lighting instead of electric lighting whenever possible.
Try task lighting and reduce overhead lighting.
If you have a desk lamp, make sure it uses a fluorescent bulb.
Don’t use table lamps unless illumination from the lamps is actually needed.
“10 Minute Rule” Please use the 10 min. rule: If you do not plan to be in your room, or office for more then ten mins. Turn off your lights
Windows and Doors:

Keep windows and doors closed in heated and air conditioned areas
Close vestibule doors when propped open.
