There are many beautiful and interesting sights in Washington DC, among them are the White House which has been home to every president of the United States ever since 1800; the Tidal Basin Lake famous for its abundant Japanese cherry trees that blooms in Spring; the Lincoln Memorial and Jefferson Memorial, Washington Monument, etc. But regardless of the beautiful tourist attractions that one could go to in the State of DC, natural calamities in the form of flooding sometimes happen. And when it does, most household residents in DC do the physical cleanup by themselves without hiring water extraction professionals or experts to deal with the situation. Prior to actual removal of water and cleaning, the starting place of the water which caused the flood should be identified as soon as possible and fixed permanently to prevent it from arising all over again. Cleaning would usually require having to remove all visible waters first by making use of a wet vacuum pump or a bucket – depending on the volume and availability of equipment. The extraction process must be done immediately or as soon as possible to avoid a higher cost of damage inflicted by the dirty waters and also to thwart of any possibility that the area becomes a source of infectious diseases due to the presence of pathogens. When all the water has already been extracted, floor coverings should be removed immediately and disposed properly. This includes removing items which came in contact with the flood water that are very porous, because the high absorbency rate of such materials has already contaminated the item in question making it very dirty and highly infectious. No amount of cleaning or fixing could reinstate it in its previously clean state; hence replacements should be made eventually if still needed. Brushing all affected surfaces with a soapy water solution removes the presence of dirt. Pay particular attention to dirt which is inserted within cracks on walls and floors. Rinse the entire area by using a mop and bucket or a garden hose with a spray gadget. When the rinsing stage has already been done, disinfecting the entire place is a must to remove remaining germ and fungal spores. Remember that disinfecting does not entirely mean total sanitation but a means of making the area or place habitable again. Never mix chlorine bleach with other cleaning products that contain ammonia as this will produce poisonous gas. Before and during application of any disinfectant, make sure to open all air passage ways and vents to avoid inhaling the vapors of the disinfecting agent upon application. After having done the disinfection phase, the whole area must be thoroughly dried out, and drying usually takes a couple of days or weeks depending on how big the place is and the weather. The re-occupation of any living space which has been previously flooded must only be done once the area is declared by a professional water extraction expert to be absolutely dry. The dryness is tested by a moisture meter which shows the amount of moisture above and below a given area. Leo Nov is an editorial staff member of RestorationSOS.

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!! Pax Sanchez

Years ago my dad taught me the benefits of composting food waste. It had nothing to do with any type of “green” movement or being environmentally friendly, no, it had everything to do with reintroducing nutrients back into the soil. Here is what he taught me then and it still holds true today. By burying your food waste and kitchen scraps (no steak bones though), you are providing a quality food source for the creatures that live in your soil. From micro organisms and those creatures that the human eye can not see, up to worms, which of course we do see. See, what happens is these creatures eat the food (and of course each other) and then finally the worms eat basically everything and their castings (worm poop) create the best nutrients your soil could ever have. By continually supplying your garden soil with food waste you are feeding the earthly creatures and they reward you with healthy soil. Now where can you get a trade off like that! Ok so here is how you do it. Get yourself a fairly large Tupperware bowl. One large enough to hold at least a week’s worth of food scraps. Then after each meal dump everything and anything into that bowl. Just do not put steak bones in there, they wont biodegrade or be eaten by the worms. Banana peels, apple peels, coffee grinds, fish, vegetable scraps, egg shells and basically anything you don’t eat, all qualifies. When your Tupperware bowl gets full, take it out to your garden and dig a hole about a foot to two feet deep and then dump the food scraps into the hole. Fill in the hole with the dirt and mark the spot with a stick or something else so that you do not dig up that area again for another three months. You need to give those little rascals some time to eat it all. Now you simply repeat this process as the Tupperware bowl gets full. If you find that you live in colder climates where the ground may freeze for lengthy periods of time, then consider starting a warm box to recycle your food scraps. That goes beyond the scope of this article but I am sure if you Googled the search term “vermicompost” you will get all the information you will ever need. So what are the two things I was talking about earlier? Well obviously the first is you are adding nutrients to your soil through composting food waste. The second is by composting your food waste you are limiting the amount of garbage that ends up in a landfill. The average four person house hold creates about 8 pounds of food waste per week. If every family in America followed this process we would eliminate nearly one billion pounds of food waste garbage a year. Now that is a lot of trash! Do your part and compost your food waste. The worms in your garden will love you for it and so will everyone else in the environment. About the Author

Are Tsunami’s Caused by Global Warming?
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.

How to Keep the Environment Clean
How to Keep the Environment Clean
If you want to keep the environment clean then you need to recycle everything you can. You should set aside a few spaces so that you can keep your recyclables in a separate area. All of your water bottles should go into one container so that it will make it easier for you to take them to the recycling center. Also you need to make sure that you recycle all of your chance and glass bottles as well because this will also help the environment. Many people do not know that you can also recycle your old newspaper, you can call to have it picked up each month.
If we are going to prevent global warming than one way that you can take part is to recycle everything you use. the best thing you can do is educate yourself on the best way that you can recycle all of your throwaway items. Maybe some of your old clothes can be donated to Goodwill this way they can be recycled and used again. Make sure that you try to avoid using plastic bags from the grocery store because once they end up in a landfill they can cause a lot of problems. Once you have started a recycle program in your house you will find that it is easy to do.
Remember that if you want to improve the environment you need to recycle everything you can. It always works better if you have specific containers that you use for each of your recyclable items. Once you make a few small steps towards improving the environment you will feel better about yourself.

You may have seen something on the news about Spokane, Washington where there is now a ban on dishwasher detergent made with phosphates. While this may seem to be an isolated case, there are actually several states (including the rest of the state of Washington) that will make dishwashing soap made with phosphates above a very small level illegal in 2010. What is phosphate anyway and why is it used in dish washing soap? Phosphate is an inorganic chemical that is a combination of salt and phosphoric acid. Because it can clean things like hard water stains, and grease, phosphates are used in all kinds of things including dish washing soap. Why all the fuss? Phosphate is a problem when it finds its way to freshwater rivers and lakes. The phosphate encouraged the growth of algae which depletes the oxygen in these rivers and lakes, killing off fish and other wildlife. While there are green alternatives out there, deleting the phosphates from the dish washing soap can leave one unsatisfied with the resulting product-and a lot of dirty dishes. Plus some of these green alternatives are pricier than their cheaper phosphorous counterparts. This has caused people to travel outside their state to obtain contraband detergent from other states-which, of course, defeats the purpose of the bank in the first place. What should you look for in a green dish washing soap? Are there green products that work as well? While there is no direct substitute for phosphorous, but there are other substances that can be used. How well they will work depends on a number of factors, perhaps the most important being the hardness of the water used for cleaning. One ingredient that be used is a surfactants. Surfactants are usually biodegradable and are used to provide cleaning power and increase the ability of the water to separate the soil from the dish. Anionic surfactants work well as detergents, but can be less than effective in hard water. Amphoteric surfactants are used for their foaming power and can often be found with anionic surfactants. There are other substitutes for phosphates, but these can be even more dangerous than the phosphates. They include nitrilotriacatic acid (NTA) and caustic alkaline chemicals (which are particularly dangerous when ingested-as sometimes happens with children). It may take some trial and error to come up with the phosphate substitute that works best in your water. It is unlikely that the ban on phosphates is going away, so it is better to start exploring the options now. In the meantime, the soap manufacturers continue work on the perfect phosphate substitute, but there are some excellent alternatives out there. “Dr. Robin”, the well known MLM Radio personality is and has built his “honorary” doctorate in the Network Marketing world and has had experience in numerous other network marketing companies.

Is it Green? – to Buying Eco-Friendly Products: A Shopper’s Guide
Is it Green? – to Buying Eco-Friendly Products: A Shopper’s Guide
Even with the economy cooling, “Green” products remain — well — if not hot, still very warm.
In a report released in February ’09, market research firm Mintel predicts 19% growth for eco-friendly products through 2013, even though the current economic downturn is expected to negatively impact sales through this year.
But “Green” can mean a lot of different things to different people. And that produces some understandable confusion for consumers as to what is truly “Green” and what is instead “Greenwashed”.
[Greenwashing is when companies over-hype the positive environmental impact of their products or policies. Tsk-tsk.]
Each and every day we review green deals and giveaways before posting them online to ensure the products being promoted are indeed eco-friendly. Some are easy to assess, like a sweepstakes for a Prius. But many times, the green aspect of a product is not as clear-cut as it is for a hybrid car.
To help us determine what’s green and what’s not, we looked to criteria established by trusted non-profits, such as Green America, the Natural Resources Defense Council and Consumer Reports, and compiled the following rules-of-thumb:
1) Above all, use common sense. Ask yourself …
- Is the product friendly to the planet?
- Does it help save energy on the road and at home; conserve water; support organic and sustainable farming?
- Is it nontoxic, recycled, cruelty-free and/or fair-trade?
2) Look for Certifications/Associations
Is the product certified or does the manufacturer have a membership association? Here is just a small sample of the many, many green certifications and associations out there. Consumer Reports “Greener Choices” website has a terrific Eco-label section which can help you sift through the meaning and relative significance of various labels.
- Household Products — Green Seal; Certified Biodegradable
- Cosmetics — Leaping Bunny; Campaign for Safe Cosmetics Signatory
- Food — Organic Certification; Marine Stewardship Council; Certified Humane Raised and Handled
- Wood — Forest Stewardship Council
- Green Business Practices — Green America Approved
3) Read the Ingredient List
If a company or product doesn’t have certification/membership affiliations, is there some way for consumers to evaluate their green claim? For example, products that claim to be natural should include a complete ingredient list.
4) Is the Product Fair Trade Certified?
Fair trade certification ensures not only that the producer of a good is paid a fair price but also that social and environmental standards are met during production of that good. Many companies may claim their products are fair trade, but you should double check to see whether the product has actual certification from a fair trade labeling organization. In the U.S., that organization is TransFair USA (though at this time, they only certify agricultural products, like coffee and tea.)
5) Is the Product Vegan or Vegetarian?
According to a report by U.N. climate experts, animal production is responsible for 18 per cent of all greenhouse emissions, most of it emitted in the form of methane from belching cattle. Yes, that’s right — gassy cows. So shifting your purchases to vegetarian or vegan products — not only food, but items such as shoes and beauty products — can mean fewer burping Bessies and less harm to the environment.
Shoppers looking to go green are welcome to use these rules of thumb as a starting point when trying to evaluate the “greenness” of product. But in order to become true green consumers, there is no substitute for first-hand knowledge. We highly encourage shoppers to become as educated as possible on what is and isn’t considered green these days, and how they can evaluate green claims. Be forewarned — trying to decipher what’s green is not a perfect science, but the non-profits mentioned above are excellent places to start your coursework. Good luck!

Water Used in Generating US Electricity
Water Used in Generating US Electricity
In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.
You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.
You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.
Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.
Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.
For a simple reason. It takes a lot of water to produce electricity.
How much? 5% of all US water? 10%? Can’t be as high as 25%?
Electricity and water?
I thought the issue was fossil fuels and greenhouse gases
The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.
Their grand total: 408 billion gallons per day withdrawn for all uses.
The number 1 spot, weighing in at 48%, was thermoelectric power.
Irrigation earned the runner-up prize at 34%.
The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.
How much water is used in generating electricity?
Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.
Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.
According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.
The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.
Nationally:
- Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
- Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
- Geothermal power plants add another 2 billion or so gallons a day.
- Most renewable energy technologies require little or no water for cooling.
These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.
Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.
How much is 3 billion gallons per day?
The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.
Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.
How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.
Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.
48% of all water use: We’re Number One!
How much is 195 billion gallons per day?
Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.
How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.
So, let’s get a higher-level view to help us.
Lake Erie holds 116 cubic miles of water.
Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.
We drain Lake Erie every 22 months.
But the water used is returned to its source.
So what’s the issue about water use?
Power generation returns 98% of the water back to its source (bay, lake, river, ocean).
It’s the environmental consequences.
The Pace Energy and Climate Center explains it neatly:
Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.
Examples include:
- The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
- At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
- The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)
The diversion of water out of the river removes water for healthy in-stream ecosystems:
- Stretches below dams are often completely de-watered.
- Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
- A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
- By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
- The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
- This often eliminates native populations of fish and other wildlife.
- Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
- As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.
The cleanest kilowatt is the one never used:
Back to those compact fluorescent lamps and LEDs
PowerScorecard.org explains the solution:
By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.
They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.
In short, reduce your use of electricity.

Last week, we introduced you to the Resource Matrix, which is everywhere, it is all around us. It is the world that has been pulled over your eyes to blind you from the truth. We showed you how economics leads to people maximizing their benefits in “win-lose” propositions: you want diamonds and gold for nothing and they want to give you useless junk for a king’s ransom. And how we’ve been hypnotized in believing what they want is also what we want. But the scales have been falling from our eyes, we’re beginning to see the truth, and the power has been shifting away from the “I want your goodies for nothing” crowd: We now realize we’re all in this together: we have greater awareness of our actions and the desire to change, and have ways to change. Hallelujah and Praise the Collective! Today, we introduce the resource called water, its parallels with fossil fuels, and its role in global warming. None of this is to dismiss or diminish the contribution of fossil fuels in global warming. Hey, just like the Special Olympics, if you participate, you get a medal. We just think that gold-medal winner Fossil Fuels has stolen the spotlight, letting silver-medalist Water Use keep us hypnotized in believing that water is a free lunch, and that nature will clear up polluted waters while getting away with breaking the rules. Water, water, everywhere, According to our friends at How Stuff Works, who I wrote about sarcastically for their oxymoronic clean coal article in discussing how true public relations stuff really works, gives us this data: Okay, so 20% of the usable water (only 0.4% of all water on Earth) is accessible, right? Well . . . no. Many of the aquifers, wells, lakes, and rivers have been sucked dry like a once-juicy fly carcass in a spider’s web. (The 18% and 1.8% you see above is like the money in the Social Security Fund: there actually is nothing there.) And many of those water sources that do still have a drop to drink are worse than the ocean’s salt water. Drink salt water and you’ll need to yawn into a bucket. Drink this water and you’ll kick the bucket. And I know you aren’t asking this burning question:
“So . . . global warming to release fresh water from ice caps and glaciers is a good thing, no?”
Percentage this, percentage that. I know I’m pulling the disgusting old government trick: drowning you in an ocean of water statistics. So let’s make it plain and simple: You bring in $10,000 a month. You’re also living high on the hog and doing your personal best to outshine every bling-bling Hip Hopster Musical Artist in materially conspicuous consumption: Aquifers and wells and lakes and rivers: Fred Pearce, author of When the Rivers Run Dry, helps us quickly understand it:
We can all save water in the home. But as laudable as it is to take a shower rather than a bath and turn off the faucet while brushing our teeth, we shouldn’t get hold of the idea that regular domestic water use is what is really emptying the world’s rivers. Manufacturing goods … consumes a certain amount, but that’s not the real story either. It is only when we add in the water needed to grow what we eat and drink that the numbers really begin to soar. (emphasis mine.) (Fred Pearce, When the Rivers Run Dry, Boston: Beacon Press, 2006. p 3)
Here are a few numbers he gives: He kindly puts water use into perspective in annual terms: —————————————– sidebar: US Beef industry’s Cattlemen’s Association: 441 gallons In an industrial beef production system, it takes an average three years before the animal is slaughtered to produce about 200 kg of boneless beef. The animal consumes nearly 1300 kg of grains (wheat, oats, barley, corn, dry peas, soybean meal and other small grains), 7200 kg of roughages (pasture, dry hay, silage and other roughages), 24 cubic meter of water for drinking and 7 cubic meter of water for servicing. This means that to produce one kilogram of boneless beef, we use about 6.5 kg of grain, 36 kg of roughages, and 155 litres of water (only for drinking and servicing). Producing the volume of feed requires about 15300 litres of water on average. —————————————– Where does all that water come from? If it comes from imported goods (Thai rice or Egyptian cotton), the water comes from those countries. When the water is collected from rivers or pumped from underground, as it is in much of the world, it’s: And when the rivers are running low, as they are more frequently, there is less water to grow anything at all. The water used in growing and producing goods around the world is known as “virtual water” and the trade of these goods is known as “virtual water transfers.” And who’s the biggest water exporting Mouseketeer of them all? The United States. When you drink coffee from Central America, you are influencing the hydrology of the region, virtually taking a share of the Costa Rican rains. The same is true within a national and regional boundaries. The Colorado River is drained so Californians can eat their Big Macs and have friends over for a Sunday afternoon barbecue. In the same way that your use of fossil fuel is measured as a “carbon footprint,” your water use, actual and through virtual water transfer, is measured as a “water footprint.” How big is my water footprint? Arjen Y. Hoekstra, professor at the University of Twente, the Netherlands, introduced the water-footprint concept in 2002. It “shows water use related to consumption within a nation, while the traditional indicator shows water use in relation to production within a nation.” (Hoekstra and Chapagain, Globalization of Water, Malden: Blackwell Publishing, 2008, p. 3) With Hoekstra and Chapagain’s water footprint calculator (waterfootprint.org), you select your country, input food, domestic water use, and industrial goods consumption, press a button, and you get your: For example, you’re in the US, eat only 1 pound of cereal a week (.4545 kg) and have a low-fat, low-sugar diet, use a low-flow showerhead, use a no-flush eco-toilet, and never run the tap while brushing your teeth. Two extremes: Three notes on the calculations, because Professor Hoekstra is European and lives in the social welfare country that started birthing hippies in Amsterdam decades before they showed up in the US at Woodstock: So how is Cinnamon’s capitalist water footprint? Answer: 650 cubic meters (172,900 gallons) I showed you mine. Now you show me yours: Get the naked truth: Calculate your waterfootprint now: Water’s running out: We return to Fred Pearce’s book to find an example, of which he has oceans: China’s Yellow River: The fifth longest in the world, it begins high in the mountains of eastern Tibet and journeys more than 3000 miles. Almost half a billion people depend on it for drinking and crop irrigation, and it’s made China the world’s largest wheat producer and second largest corn producer. Yet more than half of the lakes it feeds have disappeared over the last 20 years, and a third of pastures have turned to desert. This desertification generates huge dust storms that choke lungs in Beijing, close schools in Koreas, dust cars in Japan, and rain dust on mountains across the Pacific and Western Canada. State irrigation projects along the Yellow River soak up the majority of its water – the total official allocations are greater than the actual flow. The resulting drought could be an early warning sign of global warming. Much of the declines in moisture reaching rivers is in line with prediction of climate researchers. So how does this global warming happen? Higher air temperatures from desertification increase evaporation from oceans and intensify the water cycle. This increases atmospheric water vapor – 8 to 10% more than today. This increases global rainfall, but the rain is being redistributed: middle latitudes (read: the US) are becoming drier. Higher temperatures increase evaporation on land, meaning soil dries out faster, meaning less rainfall is reaching rivers. The higher temperatures melt glaciers and snowpacks. At first, this leads to unpredecented floods. After the glaciers disappear, meltwaters that feed rivers disappear. The combined decreasing rainfall and increasing evaporation will lower moisture by 40% in the southern and western states. The Sierra Nevada snowpack could diminish by 70 to 80 percent over the next 50 years. And some of the world’s most productive agricultural regions could dry up. Global climate is becoming more extreme: the dry areas become drier, and the wet areas become wetter. And more areas are becoming dry deserts. Loss of habitat and agricultural lands. It’s a vicious cycle. So what can you do? As Fred Pearce points out, your drinking and bathing account for 0.05% of your total water consumption. Your food and clothing weigh in at 95.00%, although I find his 12,000 gallons needed to produce a pound of burger rather wild. As Professor Arjen Y. Joekstra shows with his Water Footprint Calculator, your consumption of meats accounts for a lot, as does your guilt by association of being in an industrialized country. The obvious solution: eat fewer e-coli burgers from your neighborhood Salt and Fat Slop Bucket restaurant. The wiser solution: like your choices in energy use, become more aware of the resources needed to produce anything and the consequences. Such as luxurious cotton grown in the Egyptian desert.

How it Will Benefit Us All: Gasification
How it Will Benefit Us All: Gasification
If you search for gasification and terms like “wood stove†on video sharing sites these days you will see demonstrations of wood being burnt in little stoves which seem to something almost miraculous and quite different from our idea of wood as a fuel. These little boilers light rapidly, produce no detectable smoke after the initial lighting and firing, and burn very hot.
So what is the technique which is being used, and how might it help us all in weaning society off fossil fuels?
What you have seen is a method of gasification. It differs from combustion in that it uses just 20% to 30% of the air or oxygen necessary for complete fuel combustion. During gasification, the amount of air supplied to the gasifier is carefully controlled with the effect that only a small part of the fuel burns completely. Trials of this process have illustrated that up to 70% of the energy value of the fue used can be recovered as what is known as synthesis gas, or syngas. This producer gas can also be used for various applications similar to natural gas.
This is a part of the magic, and not one really shown in the YouTube type videos, but it makes this method even more useful. This is due to the fact that syngas can be put to useful work, in both drying the feed fuel prior to gasification and after collection and storage it can be used as a fossil fuel replacement, and renewable energy source. When a gasification plant also includes Combined Heat and Power (CHP) and/or electricity export from the site, the gains are even more impressive.
Gasification in addition promises to be the most efficient long-term solution for capturing carbon while utilizing these valuable feedstocks, and storing the CO2 for very long priods, to reduce or halt global warming.
Gasification of wood and wood-type residues and waste in fixed bed or fluidised bed gasifiers with subsequent burning of the gas for heat production is has become state of the art with designers of thes systems working hard to gain the absolute maximum efficiency out of these systems.
These wood gasifiers which are located primarily in the Scandinavian countries are used almost entirely for space heating heat generation. Gasification of biomass is the renewable fuel system preferred by many, and can be defined as the thermal conversion of solid biomass to gaseous fuel.
Gasification has been around for over a hundred years, but the benefits of biochar are only now being discovered. Furthermore, it is still a wide-open field.
Before electric lighting was available in cities there were street lamps fuelled by gasified coal. It is easy to forget that the process has been reliably used on a commercial scale worldwide for more than 50 years in the refining, fertilizer, and chemical industries, and for more than 35 years in the electric power industry. More than 75 companies involved in the development, licensing, and use of these technologies as well as engineering, construction, equipment manufacturing and production of synthesis gas by gasification from coal, petroleum coke, heavy oils and other hydrocarbons.
Gasification has been proven to be a viable technology for CO2 capture and reducing SOx, NOx, particulate matter, and mercury emissions from coal and petcoke-fired power plants, synthetic fuels production, and chemical facilities.
Plants in this category have been capturing carbon dioxide for several decades in chemical plants in China and the United States. It also has potential contributions to make to both transportation and electrical power energy markets. With ongoing concerns about the price and availability of oil, populous countries like the U.S. gasification has proven to be in high demand and quite successful. However, it can also be used in conjunction with gas engines and gas turbines to obtain a higher conversion efficiency than conventional fossil-fuel electric power generation. Gasification can help meet renewable energy targets, address concerns about global warming, and contribute to meeting global environmental targets.
Steve has built a great web site where there is a lot more information about gasification. This is a hot subject indeed for this technology which has become an essential read for all those in alternative energy and interested in taking action to reduce the impact of climate change.
