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.

With Natural Finishes Go Green


With Natural Finishes Go Green

Finishes are coatings that are  applied to the external and inside surfaces of walls to protect them from the elements and from wear and tear.  They also improve the appearance of the structure and are used to enhance the design of rooms.

Petroleum, our main source of oil-based wood finishes and paint, is a non-renewable resource.  There are now paints and finishes on the market that are derived from a renewable resource, which  in a small way, helps to reduce dependence on oil, and  contributes to a more sustainable world.

The basis for these products is whey, which is a product of cheese making, and which has a high biochemical oxygen demand (BOD).  This increases the burden on waste treatment facilities, and can also pollute our natural water sources.  In the last ten years, this by-product has been used for many new purposes, one of which is natural wood finishes.

When choosing paints for your decorating, use the low or no VOC (volatile organic compound) paints. For hundreds, no, thousands of years, earth, clay and lime have been used, both in hot and cold areas of the world.  And now this knowledge is being readapted for contemporary use. If you do any redecorating or new building, it makes sense to contribute to having green, healthy surroundings.

Low and no VOC paints have less smell and less impact on air quality.  EPA studies have shown that indoor air quality is up to five times more toxic than outdoors, mainly because of toxic emissions from paint and finishes. This particularly affects anyone with allergies, asthma, or chemical sensitivities. With the new “green” paints, there will be lower contamination of landfills, groundwater, and the ozone.

Switching will not cost you more.  Cleanup is easily done with soap and water, instead of toxic chemicals, and brushes can easily be cleaned and reused.  The paint is still washable, and is far less harmful to you, your pets, and the environment.

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?

Do We Want Too Much?


Do We Want Too Much?

What can be done about this increasingly worrying contribution to global warming?

The most important options to reduce aircraft CO2 emissions are:

Changes in aircraft and engine technology; use of alternative fuels, such as (sustainably produced) biofuels; regulatory and operational measures such as improvements in air traffic management; economic measures such as inclusion of aircraft emissions in emission trading schemes.

But, as Giovanni Bisignani, manager of International Air Transport Association (IATA), stated: “Emissions trading schemes only make sense with efficient infrastructure. The IPCC estimates that there is 12% inefficiency in air traffic management globally: we produce up to 73 million tonnes of carbon emissions each year by aircraft flying inefficiently due to air traffic management limitations”. **

On a personal level we could ask ourselves especially in the developed world: “Do we really need to fly so frequently?” The use of telework, teleconference and video conference could be largely increased to plan work and meetings. Can’t the development of land and air transportation infrastructures be balanced better according to the real needs of people and businesses? Trains could connect cities better and more cheaply for example in Europe, where the prices are not competitive with those of many flights anymore (and night train services have been reduced if not cancelled).

Life styles do matter because if millions of people want to have cheap weekends in relatively close tourist locations, many flights are needed to satisfy their desires and consequently a lot of pollution is generated. Also, our per capita emissions could be cut also by reducing the “surplus” trips, by slowing down our life rhythms and enjoying more local attractions in our free time. Who knows? We could discover the “exotic” in our own neighborhoods without flying to the Caribbean Sea…

Furthermore the relationship between the costs and the environmental externalities (i.e. costs not included in the economy like health damages caused by pollution) needs to be considered as well: there are higher marginal impacts for short-distance flights that should be considered in prices paid by passengers.

All these political, technological and personal choices are some of the good examples needed by the developing countries to follow the 21st century’s Western society along a new sustainable path which looks like the only good alternative forward.

The World Energy Crisis – How Can We Cope?


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.

Make power at home with solar and wind energy to eliminate your power bill. Get our complete guide at EnergySolutionsDIY.com.

Grass Root Efforts: Promote Earth Day


Grass Root Efforts: Promote Earth Day

What is Earth Day?

While you have probably heard the words “Earth Day”, did you know there are two observations of Earth Day? The United Nations celebrates on the equinox; hundreds of countries celebrate Earth Day annually on April 22nd. Both events were birthed in 1969, with grassroots efforts, a focus on environmental awareness, and celebration of Earth.

Events to Leading to Earth Day

Prior to 1970, conservatism was an idea held by a minority of people. The notion that natural resources would become devastated to the point of extinction did not enter our collective thought. Pollution, from our buildings, cars, and behavior, was a normal industry by-product. The idea of being the world’s steward was lumped in a mindset of ‘a hippie thing’ and not understood by mainstream America. Two previous events tilted our environmental awareness: a book and a picture.

In 1962, marine biologist Rachel Carson published Silent Spring. The book talked about the commonly used, toxic pesticides used in agriculture and daily life. The title referred to the consequences of the devastating pesticides: a world without birds. Surprisingly, Silent Spring became a hit. Americans cared, and they wanted the facts.

In 1968, the world saw the entire Earth for the first time. Apollo astronauts photographed the planet on their flight home from the moon. The Earth looked beautiful with its swirls of blues and whites. The photo provided a startling awareness: people saw Earth as vulnerable and needing human care.

Earth Day is Born

In 1969, John McConnell promoted Earth Day as a global celebration of Earth’s gifts. The equinox seemed fitting time, as it was the mid-point of spring and autumn across the hemispheres. A peace activist, McConnell first presented his Earth Day idea to an audience at the UNESCO Conference on the Environment. He wanted Earth Day to be a global holiday, where the world celebrates Earth’s wonders and gifts.

On March 21, 1970, cities across the globe celebrated Earth Day. McConnell created an Earth Day proclamation that called upon people to take action against crises of the world, such as famine, war, and poverty. The proclamation also stated that participants would celebrate an international Earth Day to create a single community and embrace Earth’s gifts. The proclamation was endorsed by well-known people and leaders around the world: astronaut Buzz Aldrin, anthropologist Margaret Mead, inventor-scientist Buckminister Fuller, Japanese environmental scientist, Y. Fukushima, American senators, U.N. President S.O. Adebo, and UN Secretary-General Thant.

In April of 1970, the world celebrated another Earth Day event. The April 22nd event also began as a way to spread awareness of environmental issues. American Senator and conservationist, Gaylord Nelson, had actively toured the U.S. in the mid 1960’s with an environmental awareness agenda. Wanting the U.S. government to take an active role in environmental concerns, Nelson presented the idea for a national conservationist tour to President Kennedy, who supported the idea. While President Kennedy’s tour did not turn environmental issues into mainstream conversations, it was a beginning in changing America’s role in environmental issues. Nelson was inspired by college campuses’ widespread Vietnam protests, or teach-ins. He thought a nationwide conservationist teach-in would get more Americans involved in environmental issues.

Nelson presented his Earth Day idea to other government officials and news organizations. He promoted Earth Day to senators, governors, mayors, and college campuses’ newspaper editors. In November 1969, he formally announced a nationwide, environmental teach-in, called Earth Day, would be held in the spring of 1970. As the event became headline news, the public reacted enthusiastically. Nelson first handled Earth Day public relations from his senate office, but with the public’s overwhelming interest, the office moved into its own organization. Founder of Common Cause John Gardner helped with a temporary office, and college students helped field the office. Nelson appointed Dennis Hayes as coordinator of activities.

Approximately 20 million people celebrated the first Earth Day. In America, participation was high in schools, which ten thousand grade schools and high schools, two thousand colleges participating. Amazing numbers, considering the event started as a grassroots movement.

Government Actions

The strength of the Earth Day movement was clear to legislatures. Following Earth Day’s success, the U.S. government passed laws that targeted cleaner living. In 1970, The U.S. Environmental Protection Agency was established. The Clean Air Act followed with a focus on reducing air pollution, with the Clean Water Act doing likewise for water clean-up in 1972. The U.S. also passed the Endangered Species Act to protect animals from extinction.

Mainstream Americans talked about recycling and conservation. In the 1980’s, many people recycled within their neighborhood recycling programs. People’s awareness of their ecological responsibility became part of their lives and actions. Children learned the importance of taking care of their environment; they were taught to care for the earth and its animals. The iconic Smokey Bear (originated in the mid 1940’s) featured poster slogans, like “If not you, who?” and “Only you can prevent forest fires. We can’t.” Americans seemed to step-up to their roles as Earth trustees.

In the 1990’s, recycling programs reduced overall waste by twenty percent. With people and government taking responsibility, companies followed suit. Manufacturers looked at ways to reduce toxic by-products and appear environmentally responsible to their customers. Their marketing campaigns highlighted eco-friendly actions, like reducing environmental waste.

Resurgence

Even with progressive responsibility, people did not celebrate Earth Day as they had in the beginning year. Celebrations were still held, but they weren’t as widely attended or announced. In 1990, the original Earth Day coordinator, Dennis Hayes, organized a worldwide Earth Day. For the thirtieth anniversary of Earth Day, Hayes planned for a global celebration, with participation from countries around the world. The event was observed by 200,000 people across the globe. The movement continued with recognition that environmental issues impacted the world and spurred the international community to work as a unit and combat its shared problems. In 1992, leaders at the United Nations Conference on Environment and Development (UNCED) recognized their joint responsibility and planned for future projects on sustainable living.

Earth Day Birthday

In 2009, visionary Simon Ford led a grassroots effort on the internet. This global community focused on a renewed urgency about environmental issues. Their first major campaign focused on worldwide environmental crises, the responsibility of mankind to solve them, and a project to unite participants across the world. The event, Earth Day Birthday, formed, as a global event to celebrate Mother Nature’s gifts.

Successful Earth Day events in the past came from grassroots efforts in spreading environmental awareness. Earth Day Birthday joins online social networks with real world actions. Earth Day event organizers and participants find each other on the web. Supporters are spreading the word on environmental issues and taking action in their own communities. Earth Day Birthday provides the 20th century, grassroots effort in reaching eco-friendly people and making an impact on the planet.
