Sometimes, simple acts such as going to the grocery store can turn into a moral dilemma. Is it better to choose the piece of organic fruit produced on the other side of the country or the non-organic version grown locally, 50 miles away? Are the benefits of chemical-free shampoo worth an extra 5 bucks a bottle? Will I really be able to enjoy a cheap chocolate bar knowing that the growers of the cocoa beans were likely not fairly compensated? As much as I’d like to say that I always buy the product that is environmentally safe and sustainably produced, in reality, that’s not always the case. First, the sheer amount of information required to be able to distinguish between products is staggering. You need facts regarding environmental impact, transportation costs, and fair trade practices, to name just a few. And there are plenty of misinformation and greenwashing campaigns out there to steer you in the wrong direction. Second, of course, there are times when the high cost of an ethically made product turns me off from buying it. Even consumers with the best of intentions have their breaking points. The thing is, companies who go out of their way to implement sustainable practices endure a greater cost of production. Sure, they can sometimes capitalize on this by marketing to conscientious consumers who are willing to pay a bit more, but the fact remains that in today’s system, environmentally minded production is punished. On the other hand, companies who move their factories (and jobs) to developing countries with lax environmental standards and cheap labor are able to make products at a fraction of the cost and undercut their competitors (while shipping materials and finished goods all around the world and adding to our greenhouse gas problems). The way it’s set up, high environmental standards in one country drive companies to relocate in places where it’s permissible to pollute in order to compete in the marketplace. Chaco, the Colorado-based athletic sandal company, is a prime example of even a well-intentioned company being forced to follow suit to maintain competitive pricing on their products. In fact, 95% of all footwear in the world is produced in China, whose poor environmental regulation and sometimes dangerous environmental problems are well known. With current talk about cap and trade emissions programs, this phenomenon may only get worse. So how do we even the playing field and reward companies for good business practices? When I think about this problem, I keep coming back to an idea I encountered in a casual conversation with a stranger while traveling. I can’t remember his face or his name, but his idea has stuck with me and festered in my mind for the better part of a year. His take was that putting the financial burden of environmental responsibility on the companies just doesn’t make sense for the reasons I’ve given above. In a global marketplace, it renders companies less competitive than those that operate free of environmental and labor regulations. Wouldn’t it make more sense to put an “environmental impact” or “ecological footprint” tax on the product itself? Ugh, a tax? Initially, I didn’t warm to the idea either. But think about it: adding a tax proportionate to a product’s ecological and social footprint eliminates the cost advantage of irresponsible production. All those environmental costs that are currently not included in our economic system would be factored in and would increase the price of unsustainably made products. This, in turn, would make moral dilemmas at the grocery store much easier. Is it more sustainable to buy distant, organic produce or local, non-organic produce? The tax-adjusted pricing should inform my decision. Can I afford the chemical-free shampoo? Yes, because the price of its chemical-laden competitors would be raised through the environmental impact tax and eliminate the cost advantage of choosing that product. The money raised from the tax could fund its implementation and other sustainable programs such as public transportation (high speed rail, anyone?) and alternative energy. Perhaps it could even make a dent in our gaping budget deficit. Won’t this cost me money? You may be thinking, “Sure, that’s a good idea in concept, but that will raise my bills – grocery, clothes, everything.” Well, yes, that’s true. But maybe if we see the true cost of the products we casually consume, we can make a more informed decision about what is really necessary to our lives. Additionally, programs such as this often have the greatest impact on the poor. But this could be compensated for by using some of the tax revenue for need-based assistance programs. Regardless, running an economic system on the assumption of infinite resources is fundamentally flawed. Currently, environmental impacts such as air pollution, water pollution, and deforestation are not factored into the cost of a product: they are considered “externalities.” These costs need to be included in the system in a way that does not punish those who engage in sustainable business practices. By taxing a product’s environmental impact, it levels the playing field for the consumer. Disclaimer Of course, I am not an economist or policy guru. I don’t know how to implement such a tax or if it would even be possible (though compared to creating a carbon trading market, perhaps it’s not that difficult). This is only the musing of a concerned, intelligent citizen trying to brainstorm ways to make our economic system fit within the bounds of our ecological constraints. What do you think? Would such a tax have a beneficial effect on our production system? Join the conversation over at our website! Jill Mueller is a conservation biologist, avid cyclist, and freelance writer.

To Reveal a Product’s True Cost An Environmental Tax?
The Plastic Bag: Ban Or Save?
As part of the conservation and environmental movement worldwide there are several campaigns aimed at banning the plastic bag. These fit in perfectly with going green at home and with our longer term life styles.
A quick search on the web will take you to the San Francisco Bay Area, “Bay vs Bag”, to the Daily Mail’s (UK) “Banish the Bags” as well as similar situations in Canada, Holland, China, elsewhere in the US and even Zanzibar.
A lot of the focus is based on the damage done to wild life, including sea mammals and birds; the effects on waste and the average number of bags used per person in different countries. In one of the lists I saw, Singapore was topping the list at 625 bags.
One of the targets is to reduce by 10% the yearly consumption of these bags.
On the other hand there are also “Save the Plastic Bag” campaigns, with the plastic industry behind it. Their main focus is highlighting what they call misinformation. Their points are based on “exaggerations” on the damage done to wild life; errors in how plastic bags are made (from ethane gas that would otherwise be burnt and not petroleum); effects of co2 vs methane; potential job losses and so on.
On the banning side of the argument, there can be exaggerations as well as questionable scientific data – questionable as in anybody can question it, after all to have an argument you must always have at least two points of view.
From the “saving” the industry point of view, there can be many counter arguments to the data that is presented. And this is quite understandable, after all their industry could be hit very badly. (This just reminds me that all businesses have a life time curve that goes from birth, to growth, to maturity and finally to demise. The time scale can be as short as a year to as long as a hundred years or more, but the end result is that it is replaced by something else).
Some of the arguments are saying that nets and not plastic bags are causing marine life casualties, that paper bags are a worse alternative (side stepping the plastic bag issue) and basically attacking the “plastic bag misinformation campaign”.
Very probably both sides are looking to make their points by reducing or ridiculing their opponents point of view. But the overall issue is still there – are plastic bags affecting our environment?
To get back to the plastic bag banning situation, where paper bags have the negative effect of more trees cut, the information that is being retrieved is very important. But it must also be as objective as possible. Having said that, we know that it takes literally centuries for plastic to degrade and this should be the foremost argument.
Just to expand a little on the paper bag argument, which is totally reasonable, the option is not to cut more trees. The options are to recycle and use bio-degradable alternatives.
In the old days, when plastic bags hadn’t been invented but grocery shops had, natural fiber bags were used and the customers were the ones who brought their own to the shop.
With just a little effort on the individual front, these campaigns wouldn’t be necessary.

Ideas For Earth Day and Beyond: Helping Kids Care For the Earth
Earth Day is April 22, and while it’s important to get involved on this day, there are things we can do as families that will make a huge impact throughout the year.
It starts with helping our kids to celebrate the world in which we live, and it continues with helping them to love it so much that they want to do everything they can to help protect it. Here are six ideas to help your kids celebrate and care for our earth:
1. Get out and enjoy it. Researchers are now saying that simply getting kids outside in nature may be the most effective way to raise their awareness of environmental issues. Suddenly, these problems that they hear about on the news and in the classroom have a real impact on their daily lives. They see firsthand how a forest or a beach or a tidepool or a meadow is teeming with life, with ecological relationships that are interdependent, delicate and complex.
To encourage your kids to get out there and enjoy the natural world, you may have to purposefully inject some extra excitement in the idea, but just at first. Take your dog (or a friend’s dog) for a walk in the woods. A dog’s love for nature, and subsequent enjoyment of it, is infectious. Create a list of things to find and make your adventure into the outdoors into a scavenger hunt.
If possible, and if your kids are old enough to be by themselves out there, find a safe place for them to play in a natural environment. Allow them to go there to get away, to sit and think or to talk with their friends. Make a point to get the kids out in nature every day. Better yet, go with them.
2. Watch “An Inconvenient Truth” as a family for inspiration. Invite some of your children’s friends over to watch it with their parents and talk about some initiatives that you can each commit to or some larger projects that you can work on as a neighborhood or community.
3. Help your kids learn about endangered animals. Together, look into organizations that help endangered animals and see how you can get involved.
4. Reduce and re-use, then recycle. Lots of kids get excited about recycling. Fewer are into reducing or re-using. Model to your children a healthy pattern of consumption. Talk frequently about the many benefits (which go way beyond environmental) of living a simple life and of being wary of a lifestyle of mass consumerism. As kids spend more time outside and less time at the mall or watching television advertisements, this shift may feel increasingly more natural to them.
5. Teach your kids about potentially harmful chemicals and how they can be everywhere in our world: in the foods we eat, in the supplies we use to clean the house, in our paint, in our cosmetics, in our lawn care products. Turn the search for these things into a game and allow your kids to be detectives, learning about and seeking out these harmful chemicals and then finding natural alternatives.
6. The next time you take the kids to the grocery store, see how you can minimize the amount of packaging that you purchase. We have been known to purposefully not purchase an item because of the manufacturer’s use of wasteful packaging. It won’t take long for the kids to realize that the best item in the store for minimal packaging: raw fruits and vegetables.
In our family, the more we can make these life changes into a game, the more apt the kids are to follow suit. Help your kids to understand how one person really can make a difference (especially when that person is part of a committed family or group) and review often the personal impact that you all have made.

City of Oxnard CA – Mobile Car Wash Rules Slated
The City of Oxnard, California is concerned with the quality of its storm water and rightfully so, as it has made great strides over the years. Oxnard CA is also home to the gateway to the channel islands with some incredible beaches and nice resort style living, and all that storm water leads to the ocean and those beautiful beaches. Thus, the city has chosen to start cracking down on mobile car washes.
This should not come as any surprise to anyone, as the city had previously implemented many programs to help clean the storm water runoff. They had developed a nearly bullet proof NPDES plan to insure clean water. The beaches never looked so good and this recent ruling to finish that job nearly a decade and a half later has come all the way down to washing of cars.
Our company had dealt with this issue in the late 80s and early 90s and helped write all the NPDES BMPs for several counties near there. The devices used are fairly easy to buy, and it really doesn’t take much, further it is my contention that all mobile car washes ought to follow the rules to protect the environment and there ought to be no excuses on that.
Indeed, over the years, we’ve worked with many cities on this, in fact, one thing we did was join the committees to help write the original BMPs for surface cleaners in Ventura County, CA where the City of Oxnard is located. A mobile car wash operator should not only follow the rules but be part of the solution. Think on that.

Saving Money and the Environment, One Bag at a Time
With the current economic problems, hopefully more people are interested in saving money and recycling. Businesses are always interested in keeping the customers they have and getting new ones.
The cost of fuel has been big in the news for years but, when compared to plastics, it’s a small percentage of petrochemical use. Saving on the use of petrochemicals for making plastics can extend the timeframe before peak oil and lower the price of fuels.
Most grocery stores offer a five cent per bag discount if you bring in your bags. You can do that in a variety of ways. One is by taking the old plastic bags back and another is using cloth bags, which can often be purchased at the store. Usually, grocers will sell cloth bags with their advertising on them at their cost, which is cheaper than an equivalent type bag can be purchased elsewhere. By doing that, the grocer gets their investment back and advertisement as well. If your grocer doesn’t have a program of that type, tell them about the advertising value and mention that you take your bags everywhere, including their competitor’s store.
If you don’t want to spend the money on cloth bags, reuse your old plastic ones. Plastic bags aren’t as durable as cloth and it’s a good practice to double bag when using a plastic bag more than once or twice.
We’ve found cloth bags to be a good investment. Most of our bags are almost twenty years old. If we save two cents a bag and buy ten bags of groceries, and do that five times a month, we’ve saved a dollar a month. That doesn’t sound like much but our cloth bags paid for themselves the first year, with the last eighteen plus years being pure savings.
Tying the bags off keeps the goods inside from spilling all over the trunk on the way home. But, tying them off presents another problem. Getting them untied, especially the plastic bags, can be difficult if not impossible. Most people consider it not worth the effort and rip them apart. There’s a simple answer to that problem. Since a picture is worth a thousand words, I have a brief slide show that explains the process. Once the bags are tied in the manner I show in the pictures, they untie easily and can be used over and over.
Since a picture is worth a thousand words, I have put together a slide show tutorial. You can access the slide show by going to the URL in the resource box.

No Bailouts Necessary – Green Transportation
Unless you have been trapped in a cave for the last seven months you are well aware of the disaster overtaking the American automobile industry. Our government is using billions of taxpayer’s dollars to prop up an industry that has been one of the leading facilitators of numerous ills in our society, which will also take billions of dollars to repair, if it is even possible to do so.
Air pollution which contributes to increased medical costs, urban sprawl, a negative balance of payments from importing oil and global warming can all be traced at least in part to our addiction to the automobile. Now that I’ve ranted about the autos effect upon our society I also greatly acknowledge that we all, myself included, greatly enjoy the mobility and freedom provided by the pernicious machine. We can’t live with ‘em and we can’t live without ‘em. What are we to do?
A lot has been written about the currently nonexistent plug-in electric car. This machine when it finally hits the market could help solve some of our problems but current pricing estimates place the car in the forty thousand dollar range. I’m sure of one thing, it won’t solve many problems if you don’t sell them and at that price I’d hedge my bets.
However, there is one personal transportation option on the market that fits into all of President Obama’s initiatives for energy self sufficiency, global warming (reduction of green house gases), health care (exercise and weight loss), environmental protection (reduction of air and water pollution), and infrastructure renewal. That option is the Electric Bicycle.
The electric bike using lithium batteries (traditional lead-acid is very environmentally harmful) can go, depending on load factors and riding habits, roughly twenty miles at twenty miles an hour on one charge. It is almost completely silent, gives off no emissions, does not use foreign oil, does not require much room to operate or park, never needs a tune up and provides exercise. It eliminates many of the drawbacks of riding a traditional bicycle for basic transportation while having few of its own. I recognize that not many of us are hardy enough to ride a bike in the rain, snow or freezing cold but that applies as well to motorcycles, motor scooters and traditional bicycles. The electric bike can get you farther, faster without arriving at your destination soaked in sweat. It can operate in many places where other motorized vehicles cannot and makes taking hills a cinch. Riding five or ten miles to work is no big deal and you can simply pedal around bottled up traffic. Usually the lightweight batteries easily detach from the bike and can be carried into your place of work or school for recharging.
Some electric bicycles offer high tech extras such as LiFePO4 batteries that are good for a thousand recharges, regenerative braking that helps recharge the battery much as a Prius does, and internal gearing to generate more torque for uphill climbs. Most electric bikes use what is referred to as a hub motor. This is not a traditional gear or belt-drive motor but is built directly into the hub of one of the wheels. This motor contains two internal rings of opposing magnets that when power is applied causes the wheel to spin. Such motors need little service and never require oil changes, spark plugs or new belts.
Electric bikes come in several of styles. There are the traditional “beach cruiser” and mountain bike styles as well as electric folding bikes, tricycles and “road bikes”. The electric folding bikes are particularly interesting. Smaller and lighter than a traditional bicycle, they easily fold up and fit into a car trunk and can be carried on a commuter or subway train with little effort. You can take the train to your stop, unfold the bike and pedal on your way. They are also useful for those who live in tight quarters and have no external place to store their ride.
For those of you that are moderately handy with tools, there are a number of electric bike kits on the market that allow you to adapt an ordinary bicycle into an electric bike. One company, Worldwide Electric Bikes, has a particularly well-designed kit that has many of the features I previously mentioned. These electric bike kits do not require a high level of mechanical ability to install. A few common hand tools, a basic understanding of how things go together and the ability to read directions is all that is required. However, if you don’t know the difference between a crescent and a hex wrench, you may wish to buy a pre-made bike or have someone install the kit for you. If you do choose to go the kit route, you can end up with a much more powerful and sophisticated bike for substantially less money than a factory built electric bike.
Electric Bicycles in all forms have long been a staple of personal transportation in Europe and Asia where there are hundreds of thousands in operation. In the United States bicycles have traditionally been dominated by the toy or recreation market or for the dedicated enthusiast. In both Europe and Asia, cycling has been a traditional means of basic transportation. I believe that this is going to be more and more the case in this country. People are avidly seeking relief from the high financial and societal cost of automobiles. The electric bicycle, while not a panacea, is definitely poised to help provide a portion of that relief.
Electric Bicycles are inexpensive to purchase, require no license or insurance, have a negligible cost of operation and are totally “green”. So, what’s not to like?

Goes to the Animals: Vibration and Noise Control
Noise and vibration control is an issue that is much more common than one might originally think. In fact, it can creep up in the most unlikely of places. A good case in point is animal lab environments. Indeed, ALN Magazine recently ran an article titled “Noise & Vibration Considerations for the Animal Lab Environment.” Therein, the publication pointed out, “In the lab animal facility setting, noise, sound, and vibration affect the life cycle, interaction, and behavior of animals.” However, because “the impact of noise, sound, and vibration is a largely undocumented factor in the research,” it’s an often overlooked issue.
“If the sound pressure levels get too high,” the article continues, “there is a negative impact on animals and structures.” Vibration control, however, is just as important to these animals as noise control in that it “is a driving force behind radiated sound.”
Obviously, exposure to noise and vibration can be detrimental to an animal’s hearing, but the risks don’t stop there. “Sound and vibration can [also] have a physical impact on animals.” Even more startling, “Smaller animals are more susceptible to the affects of sound and vibration over time and will adapt or adjust accordingly. In some cases, mutations may result from exposure to undesirable conditions.”
How can animal laboratories mitigate these problems? The magazine notes, “The designers can control items that are constant disturbances that may greatly impact the animal community. Items within the designer’s control include ventilation system design, machinery vibration isolation, wall construction, lighting selection, and computer terminal placement.”
During the design process, animal labs may want to consult with a producer of custom-molded rubber and rubber-to-metal bonded parts for noise and vibration control. A world leader in the creation of rubber molding and rubber-to-metal bonded parts can help to create an environment that is not only safe for the animals being kept there but is also conducive to a healthy work environment for the people who are employed there.
The Vibro-Insulator line of isolators and mounts, in particular, aid in the control of noise, vibration, and shock. Selecting the right type of mount for an individual animal lab’s specific applications can prove tricky, however. That’s why consultation with an expert with reputable qualifications in rubber molding and rubber-to-metal bonding can be very beneficial.
Of course, once professional advice has been obtained, browsing the Vibro-Insulator catalog allows animal labs easy navigation so they can select the correct mount for their application. Rubber Vibro-Insulators come in a variety of styles and sizes to handle most vibration isolation problems. Most of the mount styles are designed to be used in either the compression or shear direction.
Selection of the proper Vibro-Insulator for a specific application boils down to a multi-step mathematical function that an expert can calculate for the lab or into which the lab’s design team can plug the following information:
1. The maximum load that must be supported.
2. The number of mounts supporting the load.
3. The frequency of the disturbing vibration.
4. Any restrictions on the size or style of the mount based on space limitations or assembly considerations.

USA – China – A G2 For Climate and Economy?
China appears to view global warming as an economic issue, Obama’s administration is primarily focused on the current economic crisis as well, but climate change is also a serious crisis and a threat to the world’s economic system itself with all its present and predicted impacts. Don’t these global problems require an integrated economic and environmental strategy? The hypothesized summit between Barack Obama and the Chinese president, Hu Jintao, could be an important step to accelerate urgent actions needed both to face the global economic downturn and to build a solid climate pact.
China, in its last 5-year plan, sets targets to reduce national energy intensity (energy used per unit of GDP) by 20% between 2006 and the end of 2010. According to Deborah Seligsohn, China Program Director on Climate, Energy and Pollution of the World Resources Institute, this target seems to be realizable given their latest remarkable record (-1.8% in 2006, -3.7% in 2007, and -4.2% in 2008.) Last month Hillary Clinton met experts from the Asia Society and the Pew Centre for Climate Change that together wrote a report that could help the creation of this US-Chinese partnership on climate change. But the good examples from China, although not directly referred to CO2 emissions, and Obama’s ambitious plan on energy and climate will need decisions from other 13 countries (or federations such as the EU), including Russia, India, Japan to get 80% of world’s emissions “under control”. Nowadays the other 173 countries account for about 20% of total CO2 emissions, but population increase and old development patterns could dangerously increase their “pollution share” in the future: every nation will be then required to cut the CO2, but large amount of money are needed to do so. Where will our leaders take Dollars, Yuan or Euros these days?
Next steps: -264 days to COP15:
Two events along the path to Copenhagen will take place in Bonn from March 29th to April 8th: the 7th session of the AWG-KP (Ad Hoc Working Group on Further Commitments for Annex 1Parties under the Kyoto Protocol) and 5th session of the AWG-LCA (Ad Hoc Working Group on Long-term Cooperative Action under the Convention). As we can read on the UNFCCC website “this is the first of three planned negotiating sessions before COP 15 in December” and can hopefully prepare a good ground for delegations and political leaders to decide upon.

Are Tsunami’s Caused by Global Warming ?
Throughout the history of our planet it has endured a constantly changing climate. It endured an ice age and has also experienced long periods of heat. But over the last two hundred years, give or take, the temperature of our planet has been steadily increasing. This change in the climate on earth is known as global warming, and global warming is the direct result of the industrial revolution.
Because of the industrial revolution, people are constantly burning fossil fuels such as oil and coal. But by burning these fuels dangerous greenhouse gases like carbon dioxide (CO2) are then released into the earth’s atmosphere. These gases block heat rising from the earth from being able to escape into space. The same basic function that glass panels on greenhouses have, hence the name. Our burning of fossil fuels causes more than three quarters of all carbon dioxide emissions. Power plants and other stationary sources contribute more than half of that amount.
Along with increasing CO2 emissions, deforestation is on the increase as well. This is disastrous, because trees recycle CO2 and release oxygen back into the atmosphere. Because of the rise in deforestation levels the fossil fuels we burn are seriously jeopardizing our planet. We know that global warming is the cause of glaciers getting smaller and for the rise in sea levels. Plants and animals show clear and undeniable signs that they are affected in many different ways. Earth is experiencing longer seasons which results in rivers and lakes freezing later than usual and melting sooner. Without a doubt, global warming causes many changes and affects our planet in many ways but can it also cause a tsunami?
Nobody will ever forget the utter destruction, grief and loss left behind after the huge tsunami that hit parts of Asia on December 26th, 2004. Hundreds of thousands of people were killed, injured and traumatized. The areas it hit were left completely destroyed.
Generally speaking a tsunami is made up of a series of waves. More often than not the first one is the mildest. Prior to the arrival of the first wave, the shoreline recedes dramatically and often leaves the ocean floor exposed. They mostly occur where the water is shallow but they can also occur around coastal areas. In deep water a tsunami appears as a big wave and nothing more. In shallow water this is not the case. The wave can reach as high as one hundred metres, although, in all honesty, this is not at all common.
We know that tsunami’s can be caused by an earthquake, but this is not the only cause. They can also be caused through volcanic eruptions and landslides. Another cause is if a large amount of water is somehow displaced, such as when meteors happen to fall into large bodies of water. Tsunami’s are caused by events that can be, and are, affected by global warming, however global warming itself does not directly trigger the formation of a tsunami. Basically, it is an indirect cause.
One thing is certain, global warming is not a myth as some suggest. The planet is displaying clear signs that we dare not ignore.

Clean Green Computing
Green and Clean Computing
Little thought may be given to the energy consumption of computers, but as more and more computers are purchased each year, it is not just the number of computers that forces increased energy consumption but the way in which computers are being used that adds to the building energy burden. Research has shown that most computer desktops are not being used a great deal of the time they are running and are left on for long periods of time. As with other forms of energy consumption, electricity is wasted when it is not being used and this burns fossil fuels that emit carbon dioxide into the air and cause smog, acid rain and other detrimental environmental side effects.
The typical desktop computer consists of a system unit which houses the central processing unit (CPU), a monitor and a printer. The CPU may require 100 watts of electrical power; the monitor, which may be 15 to 17 inches, may require another 50-100 watts; a laser printer can use as much as 100 watts or more while ink printers use as little as 12 watts while printing. The cost for operating a 200 watt system all day and night, everyday, would be $125 annually, while the cost of operation for normal business hours of 40 hours per week would range around $30 annually. Considering the tremendous benefits derived from using computers, this figure may not appear extensive, but when multiplied by the many computers used on a daily basis in this country, the total grows phenomenally.
There are many ways to reduce personal computer energy consumption. Computers, printers and monitors can be turned off when not in use. Many years ago, it was considered harmful to the computer if it were turned on and off periodically during the course of a day. However, the internal circuitry of personal computers is designed to be protected from power damages that might result from on and off switching. Doing so will not substantially affect the computer’s useful life.
The use of screen savers wastes energy and should not be used. They go back to the days when, if not used, images would be ingrained on screens if they remained on too long, but updates in technology have long made the use of screen savers unnecessary.
The United States Environmental Protection Agency has also developed technology for computers and monitors that can be programmed to automatically power down to a lower power state when not in use. This “sleep mode” can reduce energy consumption by 60% to 70% and these “Energy Star” computers serve to gain efficiency without any loss in computing performance.
Green computing extends beyond the personal computer to the use of related devices and materials. For example, paper waste can be reduced by printing as little as possible and only when necessary, recycling waster paper, using electronic mail instead of faxing to eliminate the need to produce a hard copy, and trying to print on both sides of the page when possible. In addition, printer and toner cartridges can be recycled. Although this is a practice that has been discouraged in the past by printer and toner cartridge manufacturers, such recycled cartridges save resources and reduce pollution and solid waste. Disposing of electronics as well can be done through recycling agencies to reduce waste and provide for recycling of functional equipment.
Finally, green computing also means not buying new equipment unless there is a real need for it. Close investigations can be made regarding upgrading hardware or software before purchasing a new computer. However, if the determination is made that a new computer system should be purchased, there are “Energy Star” computers, monitors and printers on the market. In addition, ink jet printers use 80% to 90% less energy than laser printers and soon, even “Green Computers” will reach the marketplace for sale.
