Saving Energy with Your PC
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.

Mobile Car Wash Rules City of Oxnard CA Slated
Mobile Car Wash Rules City of Oxnard CA 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.

Lets Revisit Some of the Debates For the Global Warming Theory
Lets Revisit Some of the Debates For the Global Warming Theory
We have all heard about Global Warming, where the planet’s atmosphere is supposedly heating up. Of course, we as common citizens have no real proof, only what our scientists tell us, along with the Think Tanks and mass media. But how can we trust this when Global Warming researchers have been paid 100s of millions of dollars, and they know if they disagree with global warming theory the money stops being funded and they are out of work?
One of the most fascinating debate points for Global Warming goes something like this; “The majority of scientists say global warming is real and we are already seeing its impact (the drought in the Western USA and the long term drought in Australia.”
This is seriously a flawed argument and let me tell you why. You see it is irrelevant and may not even be true. After all, 55% would be most of the scientists and thus the majority, still leaving a huge contingency of doubters, with plenty of data and research to back up the opposite point of view.
Likewise, during Copernicus’ day only one man believed the world was round, everyone else said it was flat; so the “majority of scientists” argument is irrelevant; majorities don’t mean anything. If you were one of a 100 people and they all jumped off a bridge because they agreed to, would you jump too? That is illogical.
Now then, the second part of the argument has to do with droughts in the world. And we all know that droughts come and go. Remember the Dust Bowl “Grapes of Wrath” in the US? And in the 1950s Australia had a drought just as bad during the same period, same as the one they are having now. This one we notice more because there are more people demanding the same amount of water.
In California, the snowpack this year is normal and anymore puts us above normal, thus, the drought theoretically is over? So, does that mean this so-called Global Warming is over? Of course, not the powers that be, behind global warming will continue to pursue this until it’s no longer in their interests. Think on this.

Environmental Statements – How to Address Contaminated Land Issues
Environmental Statements – 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.

Antarctic Peninsula Climate
Antarctic Peninsula Climate
Antarctic Peninsula has been experiencing warming trends for over 40 years with an increase of 2-3 C, thus correlating with lower sea ice conditions in the Amundsen Sea and Bellinghausen Sea. Warming temperatures around the Antarctic Peninsula is changing the dynamics of the ecosystem. The rise in atmospheric temperature is causing increasing in melting of freshwater glaciers and ice shelves. Fresh water emerging into the sea counteracts the salinity within a regional area. Changes identified are;
• Decrease in sea water salinity up to 60 miles offshore
• Lower sea ice
• Decreased krill population
• Increased salp (open ocean tunicate that is reminiscent of a jelly-fish) population
• Increase in cryptophytes (single cell phytoplankton algae)
• Decrease in diatom phytoplankton
• Increase in carbon sequestering in deep ocean sinks
• Decrease in carbon availability in the food chain
The Antarctic Krill (Euphausia superba), a small shrimp like crustacean is the most important zooplankton species associated with the sea ice and plays a crucial role in the Antarctic food web. On a regional basis the amount of krill appear to be declining in the southern ocean. There are definitely lower trends in krill population during lower sea ice years around Antarctica. Part of the rational for the population decline is that ice algae rely on the sea ice for protection and growth. The krill need the sea ice in order to feed on the algae and phytoplankton.
Krill occur in groups or large swarms. They are less than 3 inches in size and feed primarily on phytoplankton and sea ice algae. Krill filter diatom phytoplankton out of the water column and scrape algae from the sea ice. Apart from frequenting the sea ice to feed, krill in particular juveniles, seek protection from predators in the many nooks and crannies formed by the deformed sea ice floes. Krill is the staple food of many fish, birds and mammals in the Southern Ocean. The biomass of Antarctic krill is considered to be larger than that of the earth’s human population.
Sea- ice algae utilizes atmospheric carbon dioxide for its energy source, the same as plants do on land. Krill diet of the sea-ice algae and phytoplankton is essential for converting the carbon for use in higher animals such as fish, birds, and whales. This carbon conversion is a very critical role in predatory nutrition. Additionally krill do eliminate some of the silica from the diatom shells and carbon in sticky balls that sinks nearly two miles into the deep ocean. These cold, deep waters are able to contain carbon dioxide and prevent the gas from rising to the surface, thus immobilizing carbon that is not passed into the food chain.
In recent years there have been increases in algae phytoplankton called cryptophytes. Mark Moline, California Polytechnic State University, states that the cryptophyte population correlates with warmer temperatures and lower salinity waters that are produced by the melting of the freshwater glacier. Cryptophytes measure around 2 mm, while other plankton in the Antarctic waters are much larger and measure 15 to 270 mm. Along with the increase in cryptophyte population an increase in salp, a pelagic tunicate, population has also occurred. There are differences between salps and krill. Salps feeding efficiency is capable of grazing on smaller food sources less than 4mm, whereas, the Antarctic Krill efficiency declines on any food less than 20 mm. The salps compete with krill for the phytoplankton and thus decrease the krill population. Additionally the salps feed on krill larvae, which also cause a decline in krill numbers.
The warming trend in the Antarctic Peninsula is showing a pattern of increasing cryptophytes over other phytoplankton and the increase in the salp. This influence is due to the low sea ice and the lowering of the salinity in the seawater. Salps and cryptophytes do better in the lower salinity, while the krill and other plankton are unable to tolerate the increased freshwater regime from the glacier ice melts. This selectivity gives preference to the salps as the dominant species while decreasing krill abundance. During lower sea ice seasons the density of krill declines while the salp population increases.
Carbon sequestering into the deep ocean from the algae and phytoplankton occur by both the salp and krill. Both species eliminate the atmospheric carbon received from the primary producing algae by producing fecal pellets by the salps and sticky balls by the krill, thereby, reducing the amount of carbon dioxide in the atmosphere. The salps though sequester more carbon into the cold deep ocean than the krill. However, the krill provides the most efficient pathway for carbon transfer up into the food chain. The cryptophyte dominated waters are less efficient in the food chain due to increased feeding by salps and the difficulty of the krill to utilize the cryptophytes as a food source. Migration patterns by penguins are changing, in part due to the changing krill population. Krill is a mainstay diet for penguins, and if the krill population changes, many other ecological changes occur with it.

Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel
Homemade Biodiesel Kits Are Used by First Timers to Make Biodiesel Fuel
The cost of fuel has gone up again that people are thinking of alternative ways to save up on other things just so they can still continue to make use of their vehicles. Actually, there is a better way by which we can save up on fuel without having to let go of other necessities or luxuries that we have in our life. Sometimes we need all this to keep us going. When you take away one or two, you may take away your only source of happiness. So think twice before cutting off hobbies or things that you are already accustomed to.
One thing by which we can save gas is if we make it ourselves. It is possible since homemade biodiesel kits are available for consumers to buy them. There are instructions online and there are even step-by-step videos on how to make biodiesel fuel. These are especially useful for people who prefer to see it than reading about it. The great thing about seeing how it is made is you can actually see the equipments that are being used. So you can always pattern your equipment with what is being shown.
Since you will be doing it yourself, there are a couple of things you have to watch out for. You have to watch out for methanol and lye because it is dangerous. Aside from that, since you will be making use of heat and vegetable oils, fire is always a possibility. First time makers of biodiesel fuel should be extra careful when proceeding and like any other endeavor it takes practice to perfect it.

5 Steps to a Greener Life
5 Steps to a Greener Life
Lots of people talk about trying to live a greener life, with some even going so far as to completely change their lifestyle, but most people aren’t sure how to go green because they don’t know exactly what that means. Sure, most people know the basics that scratch the surface such as reusing, recycling and reducing the amount of waste output for their homes but there many other steps you can take to move towards a cleaner, greener environment.
If you’re wondering how you can make your life greener, here are five different tips that are simple and easy to implement and that don’t cost the you anything. All it takes is a little dedication and after a few months, these five little things will become second-nature to you.
1. The next time you go shopping use cloth bags at the grocery store instead of paper or plastic. These cloth bags can be purchased for as little as a few dollars each and they’re much stronger than paper or plastic bags and will last you through years of use.
These bags help reduce waste since most people throw away the plastic and paper bags. The hardest part of using cloth bags is remembering to take them to the store, but once you get in the habit of using them, it becomes unconscious habit.
2. Replace your standard light bulbs with compact fluorescent bulbs. These bulbs use less energy and last for four to five years, almost 15 times longer than traditional bulbs. While the cost of a compact fluorescent bulb is more than your standard bulb, they easily pay for themselves over time requiring less frequent replacement and reduced energy consumption. In fact, studies show that a CF bulb can actually pay for itself within one to two months. One CF bulb also saves about five pounds of greenhouse gas carbon dioxide a month. Replacing every bulb in your home can have a huge impact on the environment and on your wallet.
3. Use public transportation. By car pooling, taking the bus, or using the subway you can cut down on the amount of gas you use and the amount of exhaust your car emits. While it may be an inconvenience in some ways, it is one of the best ways of helping the environment. Even better, walk or ride your bike to work if possible. This not only saves you money and helps the environment but it also keeps you fit and healthy!
4. Adjust your thermostat by a few degrees. By turning your thermostat down by just two degrees in the winter, you can save over 50 pounds of greenhouse gas carbon dioxide per month while lowering your heating bill. Turning it up a few degrees in the summer can likewise save you money and save the environment.
5. Finally, only wash your clothes or run your dish washer when you have a full load. It wastes water and electricity to wash and dry only a few pieces of clothing. In fact, if you can, try to wash your clothes using the cold water cycle as it uses up to 50% less energy than a warm water one.
By just doing these basics not only you can save some serious money but you can rest assured that you’re doing your part for a cleaner, brighter future. To discover more ideas you can use around your home for living green visit http://www.greentipsforyou.com!

Cheap Flights and Climate Change
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.
