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.

Your Second Hand Clothes: Recycle

Landfill in the UK is becoming a huge problem. With the drop in the price of recycled products, the issue is what to do with all of the waste that we produce. The breakdown of waste in landfill sites creates huge amounts of the greenhouse gas methane. There are also many products that will not breakdown and will remain in the environment for ever with the potential to contaminate water supplies.

Traid, a charity specializing in the recycling of textiles reports that 900,000 tons of shoes and clothing are thrown away each year in the UK. Only 200,000 tons per year are recycled and the rest is dumped in landfill. The government estimates that similar amounts of between 550,000 and 900,000 tons of textiles are thrown away each year.

In addition to the problems of waste and landfill in the UK, there is also the consideration of the energy used and waste generated by the manufacture and distribution of clothing and textiles. Growth of cotton uses a huge amount of chemical pesticides and environmentally damaging cultivation methods. The manufacture of man made fabrics also has a huge environmental impact with. Demand for polyester the most widely used synthetic fabric has almost doubled in the last 15 years. The manufacture of polyester uses large amounts of crude oil and an energy-intensive process. It releases emissions including volatile organic compounds, particulate matter, and acid gases such as hydrogen chloride, all of which can cause health problems for workers by causing or aggravating respiratory disease.

Second hand clothing is becoming more popular as people begin to recognise the real costs of fast fashion. Consumers are becoming more aware of their buying choices and ways that they can help the environment.

Finally, there is one more great reason to recycle second hand clothing. Just because you are fed up with a piece of clothing or it does not fit you nay more, it does not mean that it has no worth. You can make sure that the worth of your second hand clothing is realized by swapping it at a swishing party on a clothes swapping website, selling it or donating it to your favorite charity.

This article was written by Ceri Heathcote for posh-swaps.com, a website for swapping, buying and selling second hand and vintage clothing.

Clothes swapping and buying and selling second hand clothes is a great way to reduce the impact of fashion on the environment and to save money.

The World Energy Crisis - How Can We Cope?

The world has some decisions about sources for future energy. The increase in population and increasing demand present a problem. The cost of conventional non-renewable energy sources is on the rise. Oil, gas, water, coal, and other natural resources have a limit to their supply.

Gas, Oil and petroleum products are more expensive than ever, and the supply is running thin. Many may think that the planet may never run out of these however it seems that drilling these supplies is becoming ever more difficult. There have been three major energy crises thus far.

Due to the shortage of resources and decreased output, the cost of these energy sources has increased rapidly over the years.

How long will it take before all of these resources are exhausted? The truth is that we really do not know. Experts say that 50% of the world’s supply of available oil has been exhausted. Every day the demand is increasing and it could take mere decades to exhaust the supply of crude petroleum.

What could possibly be done about this situation? How can we as a society cope with the energy crisis at hand? What can we consumers do about this? We can all start by understanding the importance and impact that energy has in our lives. These supplies of energy should not be taken for granted. Additionally we should avoid wasting energy.

There are simple things that we could do to conserve such as getting involved with a car pool, check our car tires for proper inflation, and using fuel efficient vehicles. If we can cut down on our use of fuel and oil in everyday activities we can be further prepared for the impending energy crisis.

Another way that we can cope with the energy situation is by utilizing renewable energy sources. Solar and wind power systems are becoming ever more available. These power solutions are feasible, cost effective and environmentally friendly. In addition, you save on your power bill and help contribute towards a better future for our world.

Helping Kids Care: Ideas For Earth Day and Beyond

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.

Tropical Rainforest Vs Development

I few weeks ago I came across an article about the deforestation situation of all the tropical rainforests. It talked about the main causes this beautiful places, origin to thousands of different life forms, are being damaged by people in so many different ways, among others: subsistence agriculture, colonization, tourism, and civilization development (savetherainforest). This latter caught my attention the most, because last week I went to my teak farm, and I got to see with my own eyes how a highway development affects our rainforest and trees so badly.

My teak farm is located about 1 hour drive from Panama City, it is located in the Colon province, home of Colon City (second biggest city in our country, Panama). Last year the government decided to build a long overdue highway connecting both cities (of course I am all for improving the quality of life of my countrymen) but I can not agree with the amount of deforestation that took place in order to build this highway.

Hundred of acres deforested in order to make way for four lanes that will bring better days to a lot of people, no doubt; but also brought a lot of disorder and chaos to a well established eco system that has being here long before us, and will continue to be here for (hopefully) thousands or millions of years after every single one of us has left this world.

Since development of cities is inevitable, specially today where commerce since to grow exponentially, cities expand rapidly, and the whole world seems to be at everybody s fingertips, we need better way of transport and communication, but could we also be more interested in both preserving and saving tropical rainforests and trees? The answer is a big OF COURSE! I would have loved to see our government promoting the planting of trees in different areas of our country in order to make up for the ones lost during the development of this highway, or during the construction of so many other infrastructures around the country. Also having more people come forward and speak up as energetic and belligerent they are about so many other problems we have on this planet. Maybe all we need are more ways to let people know about this, get them involved.

Since so much rainforest is lost every year, roughly about twice the size of the state of FLORIDA, this has become a problem for every single one of us earthlings, I think we need to get the word out, raise awareness and get people involved! Tropical Rainforest account for only 2% of land surface but through photosynthesis of trees they take massive amounts of CO2 emissions and make air clean and breathable again for every one of us. SO WE ALL NEED OUR RAINFOREST AND MORE TREES!!

How to Address Contaminated Land Issues

Under the relevant European Directives, an Environmental Statement is the formal product of an Environmental Impact Assessment. Environmental Statements are often organised in a way that describes the environmental baseline, mitigation and effects for each type of environmental receptors: ecology, water resources, archaeological resources, human beings etcetera. Contaminated land is often managed in the same ways as the various environmental receptor groups, although it is principally a cause of impacts rather than a receptor. It also often refers to a pre-existing condition and its damaging effect is on a variety of different receptors such as human health, structures and buildings, surface water features, groundwater features and ecology. This often means that land contamination specialists struggle with integrating the issue in a logical manner in an Environmental Statement. Sticking to the structured approach of an environmental statement is essential to ensure a clear description of the existing environmental condition, the potential impacts and the actions taken to avoid, minimise, offset or manage the impacts. This article is based on UK practice and legislation, although fundamentally the issues should be similar within other contexts.

Contaminated land is in many countries considered on a source-pathway-receptor basis. This is important to understand the impact land development can have on the issue of contaminated land. Development can interfere with any of these three elements. It can introduce sensitive receptors by changing the use of land, for instance by building new residential units on a site that was previously used for heavy industry. New pathways linking pre-existing contamination with an existing receptor can be formed, for instance when piling through a non-permeable layer connecting a layer of contaminated soils with a deep aquifer. Finally by introducing pollutants on the site a development project can introduce a potential source of contamination.

The second element to consider is the structured approach of an environmental statement. Apart from the introductory and procedural elements described in the environmental statement, a good environmental statement comprised the following sections:

• environmental baseline conditions
• potential environmental impacts
• mitigating measures
• residual environmental impacts

There should be a logical relation between the different sections. Any receptor that is affected and described in the section about the potential impacts and effects should have been introduced in the section describing the baseline. Any material impact should be assigned a mitigation or management action etc. Implementing this structure allows a clear description and understanding of the environmental impacts and the way it will be managed.

Applying these principles to contaminated land will result in a baseline condition section that describes the current sensitive receptors that are present within the potential sphere of influence of the development, the sensitivity and importance of these receptors, the presence of any pre-existing contamination and the presence of actual and potential pathways. The next section, potential environmental impacts or effects, first considers the impacts that the development will have in terms of the introduction (or removal) of sensitive receptors and the creation of new pathways between existing and potential pollution sources and receptors. In addition this section will describe the potential environmental impacts that are associated with the introduction of new sources of contamination. In the third section, mitigating measures, a description of the actions to mitigate each of the impacts that may occur should be provided. Finally a statement of the residual impact of the development is provided in the last section: residual environmental impacts.
