Water Efficiency


Water Efficiency

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Their grand total: 408 billion gallons per day withdrawn for all uses.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.

Have You Got Earthday Business


Have You Got Earthday Business

The sun is shining across the hills of West Cork as I listen to the story of Earthday told by a team of evangelists with nothing but Earthday business on their minds. In 2008, visionary Simon Ford started a group to bring like-minded, positive people together in socially conscious activities. He called the group Social Traffic and right now that group has Earthday business on its mind.

The group’s first major campaign centers around Earth Day with an event named, Earthday Birthday a global birthday party for Mother Earth. Earthday 2009 and the celebrations that will go with it is all set to clamor its way across the social media landscape like some all embracing vine, covering the sometimes harsh elements of the online world with a softer, greener facade which many hope will last for more than a lifetime.

Earthday 2009 is a global celebration and a day to spread awareness of people’s destructive impact on the planet. But before you jump right in there and start changing the world on a massive scale here’s a few simple things you can do to make a difference right now, tomorrow and every single day after that.

Here’s my list of top five things to do to celebrate Earthday 2009 and reduce your impact on our planet;

1. Plant a tree or two. If you’re feeling energetic plant a whole field full.

A tree will absorb CO2 and other forms of pollution, provide a home to hundreds of creatures, help to create and retain soil and performs a whole host of other ecological functions. And, in case you needed a reminder, will leave a lasting legacy of your time on the planet.

2. Walk to work for a day, a week or a whole month. You’ll feel better and the earth will be a much healthier place to live too.

You might even want to think about joining a car sharing scheme and make it a permanent part of your work life balance to drive to work only one day a week and sleep the other four in the passenger seat while someone else does all the hard work!

3. Dry your dishes naturally. Turn off the dishwasher at the dryer stage of the cycle and leave your plates and cutlery to dry themselves for a change!

4. Turn off all your plug sockets before bed. Maybe spend the evening in the dark for one day a week and treat the kids to a few ghost stories before bedtime!

5. Don’t be a water importer.

Get rid of your supply of bottled water, keep a jug of fresh tap water in the fridge and reduce the damage we do to the environment by producing plastic bottles to hold gallons of mineral water that tastes no different to the clear, fresh water that is piped through your home.

So, if you’ve got business on your mind this Earthday, perhaps you should take a few minutes to look around you and realise how precious our planet is and how beautiful that small piece of turf is right outside your window.

If you want to know more about this subject and how you can make a difference take a look at this great squidoo lens all about Earth Day Birthday right now.

Neil Ashworth is a member of Simon Ford’s Social Traffic Team who are raising awareness of environmental issues using the power of social media marketing to support the Earth Day Birthday campaign.

Green Tip - Moms Use Clothe Diapers

Sure, this is a little messier than the easier, disposable version. However, do you even realize the amount of disposable diapers that are filling landfills?? Cloth diapers are a choice that every mother should seriously consider. Let’s look at some facts that are quite alarming…

Disposable Diapers Sobering Facts:

* from birth to about 2-1/2 the average child will go through about 7,300 diapers

* the cost for that is about $2600

* 18 billion diapers enter landfills each year

* disposable diapers make up about 3.4 million tons of trash

* health risks such as fertility issues in males, eyes, nose and throat issues and even asthma-like symptoms have been connected to disposable diapers!

* long term negative affects on animal and water life.

* the chemicals that make disposable diapers white increase the risk of cancer

* affect development

* they use more water. yep. you may need to wash cloth diapers, however, way more water is used making disposable diapers!

* a study, conducted by Anderson Laboratories in 1999 and published in the Archives of Environmental Health, found that disposable diapers release chemicals called volatile organic compounds (VOCs), including toluene, ethylbenzene, xylene and dipentene. They have been shown to have toxic health effects, such as cancer and brain damage, when used over time or high exposure.

* they use 1.3 million tons of wood pulp. that’s about 1/4 million trees every year.

* they take up to 500 years to break down.

* more viruses than you want to know about…including polio, survive for two weeks or more after disposed of.

There are many many many more reasons to avoid disposable diapers. However, I think our readers are intelligent and the above information is enough to get you thinking! Research for yourself. You will be shocked!

Go for organic natural reusable cloth diapers. You will not only be helping the environment and saving money, you will also protect your sweet precious love bugs from harm!

Marvell’s digital PFC chips


Marvell’s digital PFC chips

So Needed in Our Thinking, Mindset, Attitudes, and Concern

Global Warming and Climate Change have been frequent phrases used over these past few years, and in various places there has almost been a panic. We hear of National Leaders using words like Saving the Planet, as if there was anything any man could do to save, rescue or prolong what Almighty God has created.

This is a time for not being afraid. Everything is being shaken - climate - moral - spirituality - the banks - investments - the Money Market. This is exceedingly serious.

Three times we read in the Word of God - in the Old Testament and in the New Testament too - that this present world will perish - that it will wear out like a garment - and that God will roll it up like a worn out jacket that is ready for discarding and dispense with it. Of course, we also read that there will be a new heaven and a new earth, and it will all be very much centred on Jerusalem.

Now, this is not a crank creed or extremist belief. This is mainstream Bible revelation.

Yes, there is a dilemma in as much as we wonder what we are to do just now, and that is where helping the poor and ministering to the poor is vitally important.

Invest in the poor. Invest in ministries that minister to the poor. Having been in Uganda and Kenya over these past years, and having recently returned from Kenya and from the poorest parts of Nairobi and Kisumu and Bungoma, there has been a slight degree of comfort in the knowledge that we have been able to give a little to alleviate the plight of those who are truly poor.

Normally, when we say we have nothing in our pockets, there might be a few Pounds or a few Dollars in our pockets, but when they say they have nothing the have NOTHING!

Jesus Christ was committed to all types of people and came to save sinners - those who were rich and those who were poor - but He gave us the task of caring for and looking after the poor, knowing that we will never be able to complete that task. That will not be completed until Jesus Christ returns.

Yes, we have to be concerned about our carbon footprint but we must not get all this out of proportion. We will not save and rescue the planet, and there is no point in praying against what the Word of God dictates will happen one day.

And yes, much of the suffering among the poor is caused by man’s sin.

There is plenty of food in the world, but man will not share it as he ought to - nor will he permit the relief agencies to do what they can.

There are millions who could be helped within two or three months with food, water, and medicine, if only those in Governments would permit people with a heart for the poor to work and serve and use their talents and energies in a positive productive manner.

Having done that, man can then start to work on the drainage and sewers, and mosquito nets for all who need one!

Injustice is one root cause of so much suffering, coupled with greed, corruption and rebellion.

And, we do not have to look at Africa to see this clearly. It has been on-going in the banks and insurance companies and the big commercial concerns over these past years and all this is coming to light just now. Jesus Christ taught that everything which was done in secret would one day be shouted from the house tops - and that is happening too.

The problem is not the icecaps but the cold calculating corruption in the hearts of men. Environmental abuse begins in the heads and minds of selfish self-centred man.

And yes again, we will do whatever we can to minister to the poor, which includes challenging those poor souls who have creamed of Millions and even Billions of Pounds and Dollars.

Do they not believe that one day they will have to stand before the Judgement Seat of Almighty God and answer for their words, their deed and decisions.

Yes - make a difference. Do what you can to challenge those who have made such a mess of things and get them to clean up their comfortable lives and their distorted thinking and demonstrate such repentance by serving the poor and ministering to their needs.

THE 3 Rs - Reuse and Recycle, Lazy Ways to Reduce


THE 3 Rs - Reuse and Recycle, Lazy Ways to Reduce

The 3 Rs (Reduce, Reuse, and Recycle) is no longer simply a mantra for environmental activists, it’s a ticket to saving you money while you consider the planet. The 3Rs ask you to buy less, reuse more, and recycle products at the end of their useful life-wonderful guiding principles for reducing our environmental footprint and bringing our lifestyles into balance with nature. But in practice, how many of us are really willing to cut back on the stuff we want to own, to reuse what we’d like to throw out, and to recycle when doing so is often incredibly inconvenient? Fortunately for budget-conscious Lazy Environmentalists, the 3Rs are receiving a twenty-first-century facelift, making them easy to implement and even easier on the wallet.

Reduce, the first of the 3Rs, releases you from the hassle, expense, and waste of unwanted stuff while helping you use less energy and create less trash. And while most of us can’t imagine life without our most prized four-wheeled possession, the first place to embrace Reduce is with our cars. That’s because our automobiles generate about half of our personal greenhouse gas emissions-the other half comes from our homes.

Today, you can enjoy the freedom of being in the driver’s seat while eliminating all of the expense of owning-or leasing-and maintaining a car by joining a car-share service. Zipcar is leading the way. Available in more than 40 U.S. cities, Zipcar lets members locate cars conveniently parked at designated spots around the city and reserve them for an hourly fee (typically between $10.50 and $16.50). Members arrive at the parking spot, swipe their membership card over the windshield sensor to unlock the door, hop in, and go. There’s no need to pay for gasoline or insurance; Zipcar has got you covered. You won’t sacrifice your ride either; Zipcar lets you choose from models like the BMW 325, Mini Cooper, Honda Fit, Volkswagen Jetta, Toyota Prius, Honda Civic Hybrid, Volvo S40, Mazda 3, and Subaru Outback. According to the company’s surveys, over time Zipcar members reduce their car usage by as much as 50 percent. Zipcar estimates that each of its cars removes the equivalent of about 15 privately owned vehicles from the road. Other car-sharing services are popping up across the country and around the world. Visit Carsharing.net for a comprehensive list.

Reuse-the middle child of the 3Rs-has been a part of our lives before we were “eco” anything (eco-conscious, eco-savvy, even a tentative eco-curious). Think about it: Every day, we reuse items like T-shirts, cereal bowls, and underwear without a second thought. We don’t toss them after one use. We reuse. The secret to twenty-first century Reusing is to discover how to reuse other people’s really cool stuff as well as our own.

Reuse logic is in effect at Goozex.com, where gamers gather to swap their video game. Visit the website, create an account and list the games you own that you’d like to trade. Then Goozex quickly locates other gamers who want them and makes instantaneous matches for you. With each game you mail, you earn Goozex points, which you can then use to acquire the games you want from other members. Instead of spending lots of money on new games (and paying for all that packaging waste), you’ll pay Goozex $1 each time you receive a game. Whether you’re partial to Xbox, Wii, Nintendo, or many other gaming platforms, the Goozex trading community has got you covered. Get your reused copy of Call of Duty 2 or NCAA Football 09 today.

Swapping websites are emerging in all kinds of categories. Bookworms can browse more than two million titles available for trade at Paperbackswap.com. Movie collectors can visit Swapadvd.com to trade both new and classic DVD titles. CD fans (you know you’ve still got ‘em) can tap into more than 130,000 titles available at Swapacd.com. And new and expecting parents can trade for baby strollers, bibs, bedding, bumpers, and more at Zwaggle.com.

Recycle, the last of the 3R trio, is the most transformative of the Rs. When we recycle, we’re giving used products the chance to be reborn as something new. That’s especially the case thanks to companies like Preserve that has partnered with Stonyfield Farm to recycle its yogurt cups-from organic yogurt, of course-into ergonomic plastic toothbrushes, razors, and an assortment of colorful kitchenware (and now also does the same with Brita pitcher filters).

TerraCycle, another green innovator, is on pace to redefine much of America’s relationship with trash. The company that began with its signature Plant Food-made from worm poop, packaged in empty Pepsi bottles and sold at the likes of Home Depot and Wal-Mart-has evolved into an innovation powerhouse that continually introduces new products made entirely from waste. Take the E-Water Trash Cans and Recycling Bins available at OfficeMax for $10.99 each and made from crushed computers and fax machines (that would otherwise end up in a landfill). Or the rain barrels and composters made from Kendall-Jackson oak wine barrels that sell for $99 each at Sam’s Club. They’re both prime examples of a company that sees opportunity where others see garbage. In so doing, TerraCycle helps us make attractive choices that are mindful of the planet and our wallets.

The Queen of Re-Use


The Queen of Re-Use

If I gave my family questionable marks on its efforts to reduce, I admit that when it comes to re-using I am the Queen. When I was a teenager there was a song, ‘I was country, when country wasn’t cool.’ Well, I was re-using back when it was called hand-me-downs and everyone looked down on you for wearing them. Honestly though, I can remember being about five and having a distant second cousin visit. She had brought a bag of clothes that had been her daughter’s, who had died. That may sound morbid, but I think my smiles and thanks for the ‘new’ clothes may have helped to let go of not only the clothes, but a bit of her grief as well.

If you were to look in my three year old’s playroom, most of the toys you would see have been given to her second-hand from friends, purchased at charity shops or even salvaged from the bin…including her wonderful Little Tikes kitchen centre.

But my re-using does not stop there, if you open my kitchen cabinets you will see stacks of old containers that once held spread, cottage cheese or something else. With the exception of the air-tight sealing bowls that my husband uses to transport his food to work each day, we do not purchase or use Tupperware, Serv-rite or any other type of plastic wear. And those plastic containers that once housed my produce such as strawberries, blueberries and peaches are now being re-used as pots for my spring seedlings. I also have a cabinet full of sauce jars that I am looking for ideas on how best to re-use. I have already filled several with nuts, bolts, nails and the like. But even after getting organised myself, I just can’t bring myself to throw these into the recycle bag when I know that they are perfectly re-usable as they are. As I mentioned yesterday, I re-use the few plastic bags we get from quick trips to the corner store for bin liners in the bathrooms.

I have even taken to re-using my daughter’s Fruit Shoot bottles by refilling them with concentrate fruit and water. Of course, a tad of a warning on this one: do not freeze plastic bottles as it can cause a cancer causing chemical to leach into the drinks. So I always replace the bottles after a few uses just to be safe. But then they can go into the recycle bag (but that is tomorrow’s topic).

Even dinner last night was re-used food; better known as left-overs. Anyone that reads my blog knows I have dozens (hundreds?) of ideas for re-using food as soups, smoothies, casseroles, stir-fries or just re-heated and served. I call this creative cooking and make it a staple of not only our family’s diet, but of my blog as well: offering recipes to my readers.

I think one of the most beautiful examples of re-using is the folk-art form of quilting. Not only can worn-out old clothes be turned into colourful quilts, but they can tell a story: our history. I have also heard of people braiding old cloth to make rugs as well. Last year at the Green Show, I bought my daughter the cutest little purse made from old plastic juice boxes by a women’s cooperative in the developing world.

Thinking back to my own childhood and the used toys and clothes that I was blessed to enjoy, I am glad that it has become the ‘cool’ thing to re-use. Not only do these items still have good life left in them, but they remind us that we, ourselves, re-use life’s lessons to improve our world. So next time before you toss that item into the bin or even the recycle bag, stop and ask yourself could it be re-used instead: perhaps that wine bottle would look nice on a table with a candle or a few flowers or could that old t-shirt be cut into squares and used instead of paper towels or how about making puppets with old and mismatched socks. The ideas are limitless…I hope you will share your favourites with me as well.

Terri O’Neale is the mother of six; ranging in age from 3 to 22. She has been both a working and stay-at-home mother at various times in her life. She was also a single mother for almost five years, before re-marrying the love of her life at the age of forty. Obviously, she has a life-time of training in raising a family on a tight budget. In addition to these real life experiences, she possesses a bachelors degree in health education and a minored in environmental management in her masters programme.

Terri feels strongly that this is one of the most challenging times in history for the family, but she also believes that families with the will and resolve to address the pressing issues of saving money, becoming greener, leading healthier lifestyles and spending more time with one another can endure these challenging times and come out victorious in the end.

Through Frugal Family articles, blogs, videos and social networking, she helps modern families rediscover some lost art forms such as cooking, sewing, and gardening. The goal is not to go back in time or become fanatical, but to help all families find simple and effective ways that fit into their lifestyle to make moderate changes with huge impacts.

Water Efficiency


Water Efficiency

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.

  • 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.

Water Extraction in DC


Water Extraction in DC

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.

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!

Is it our fault? Global Warming


Is it our fault? Global Warming

Global warming is one of those topics that I still find myself wondering what to truly believe. Is our CO2 production really the culprit in the warming of the planet? Or are there some other larger influences at play here. I have a hard time believing mankind’s activities are solely to blame for any kind of climate change.

After all, CO2 is only one of many greenhouse gases that can affect the warming trend. Water vapor is by far the most abundant and effective at influencing the greenhouse problem. But I don’t see any kind of public concern over evaporation of water in any way at all. Okay, I realize that there is little or even nothing that can be done about that but the point is CO2 is just a tiny fraction of the greenhouse gases affecting our climate. So if water vapor is by far the largest greenhouse gas then why are we so obsessed by manmade CO2? Mankind’s ego.

We see a small trend in the planets temperature rising and of course we assume it must be what we are doing. I am truly pleased to see that we are taking an interest in reducing pollution from cars and industry but I really have my doubts about the connection to global warming at least in the significant way the media would like us to believe.

The media is sounding the alarm bell which of course sells more newspapers than reporting the less extreme predictions surrounding the warming trend. The weather models produced by scientists predict a reduction in the temperature differences between the poles and the equatorial regions. This will in fact reduce the number of violent tropical storms, as there will be less of a temperature discrepancy to stimulate them. Also the warming of the regions closer to the poles will allow agricultural pursuits in areas where it was not possible before. Food production would be able to rise accordingly. The alarmist media isn’t interested in those types of stories it seems.

The change in the world’s temperature is just that, change. There is irrefutable evidence that the temperature of the planet has and most likely will always be changing regardless of what we are doing. What are we so afraid of? Do the alarmists doubt mankind’s ability to adapt and cope with a few degrees of temperature change or even sea levels rising a meter or so? There will doubtless be hardships and even some displaced people in some regions but man has the ability to adapt and change. We have demonstrated this through the ages. I am confident that we will not only survive these changes but also learn to use them to our advantage.

I live in Canada and if you ask anyone living north of the temperate zone about rising temperatures the resounding response would be “bring it on, we could use a little global warming around here”. Life will improve greatly for huge numbers of the world’s population with a couple of degrees increase in the planet’s temperature. Migration to areas that were before considered uninhabitable by most will have a more moderate climate allowing for farming and other activities. You can’t sell newspapers with stories like that.

The scientific data indicates that 1998 was the warmest year on record. The planet has been cooling ever since. A quote from Dr. Oleg Sorokhtin of the Russian Academy of Natural Sciences “The earth is at the peak of one of its passing warm spells, It’ll start getting cold by 2012, and really, really cold around 2041″. So who are we to believe? A respected scientist or Al Gore who has made millions from his crusade for the planet and his questionable agenda and phony pseudo science.

If the planet is warming I can honestly say I hope so. We will get by and probably do well in the process. What really concerns me is the muzzling of real science in the debate. An objective media would go a long way in helping us all deal with the facts as they truly are. Focusing on the alarmist perspective only causes undue fear where none is warranted.

Is driving our SUV’s and minivans really the problem here? Or is our planet just going through another climate cycle like it has done so many times before? The only thing I know for sure is I can’t count on the media to provide the answers.
