The Saturday Morning Paper


I love Saturday mornings! I don't have to jump up to alarms going off, fight morning traffic, or rush to get kids to school by the bell.  My husband is home to (sometimes) cook breakfast, and Saturday mornings seem to bring a peaceful start to the weekends.


Let Me Read

One of my favorite Saturday morning activities is to quietly sip on tea and catch up with my favorite bloggers on my Google Reader.

I thought this Saturday would be a great chance to catch up on Upcyclers post you may have missed in the hustle of every day life.  Here are some great blog archives from our two favorite topics...

The Economy, Energy Consumption, and Upcycling: The Hydrocarbon Stranglehold on our Economy

Last month, we made connections.  We talked about the ways that hydrocarbon dominates our economy, but we just barely scratched the surface.  This month we are going to really examine how dependent our current system is on fossil fuels, and all of the damage this dependence is doing to our precious Earth.

The Fossil Fuel Dilemma

Last month's article focused on oil, but that isn't the only fossil fuel we are dependent on.  Coal and natural gas are also large parts of our economy, and sources of energy, and this is the dilema.  So let's take a look at those, and see how they are important.

Coal and natural gas are both important in the production of electricity.  According to the US Energy Information Administration (the EIA going forward), coal led the way in the production of electricity, with natural gas a close second, and nuclear in third place.

Graph taken from the EIA's website provided in the link above.


Coal is also important in the production of steel and iron.  Coking coal is used to heat steel and remove impurities.  The World Coal Association says that 70% of all steel is produced using coke.  The other 30% is produced using an electric oven to melt the steel, but that takes a lot of juice, and there is about a 40% chance that the juice is being supplied by a coal-fired power station.

You can see that very little oil is used to produce electricity.  Most oil is used for transportation, in the form of fuel.  The US Energy Information Administration says 4.6% of all petroleum was used to produce many everyday products.

Only 12.7% of all electricity produced came from renewables.  While those are better numbers than we have traditionally seen, that leaves a lot of room for improvement.  However, most of this renewable energy is from hydro.  Unfortunately, we really don't have room for another Hover Dam, and even attempting something similar to it would have devastating effects on the local ecology.  So with so little of our energy coming from renewables, how much damage is this doing to the environment?

Environmental Impacts

The environmental impacts of all fossil fuels are devastating.  It is common knowledge that they are all responsible for air and land pollution, water pollution, and destruction of ecosystems.  This is the nature of fossil fuels.  

Mining has always been a dirty business, but let's look at the methods used to extract coal, oil, and natural gas.  While they all pollute the land, air, water, and destroy ecosystems, they also all have their own unique atrocities associated with them.

Coal is mined using two methods.  One is the traditional method of boring into the mountain, and then removing the coal from the seams.  The other is mountain top removal mining.  This is exactly what it sounds like.  They blast up to 800 ft. off of the top of the mountain.  They then remove the pieces, called "overburden", and harvest the freshly exposed coal.  In places like Appalachia, where there were no glaciers, that top soil they are removing is over 10,000 years old.  The coal companies will put top soil back on the mountain, and attempt to regrow vegetation after they are done harvesting the coal, but it is never the same, and you can't replace 10,000 year old top soil, and it doesn't replace the 800 ft. taken off of the mountain that took millions of years to form.

Not only is there deforestation, and damage to the top soil, but they dump the overburden into valleys, which pollutes the water supply and destroys entire ecosystems.  This type of mining only accounts for 5% of coal in the US, but in Appalachia, it is closer to 30%.  The coal companies are tearing through these mountains at an alarming rate, and only for the sake of their profit margin.  It absolutely needs to be banned.  They do not need to use this method to harvest coal.  There is plenty of coal to be had without mining in such a disastrous way.  They do it because it is cheap.  And the result?  Well, it looks like this...



Another particularly damaging aspect of coal is the soot produced when burned.  It is by far the dirtiest form of electricity production.  It causes smog, air pollution and acid rain.  There were 594 operating coal plants in the US in 2009, according to the EIA.

We have all seen the images of oil spills.  Exxon, the BP spill in the gulf, the list goes on and on.  The damage to the wildlife is obvious, and it goes beyond just the initial contact, because there is no getting that oil out of the water.  Yes, they release Corexit, a chemical that makes the oil sink to the bottom of the ocean, but that isn't a good solution either, because it will take the oil longer to degrade on the bottom than it would on the surface.  It is too cold, and oil degrades faster in heat.  The Exxon Valdez tanker crashed about 23 years ago, and they are still finding oil on the shores of Prince William Sound, Alaska.  Proving that the damage done by a spill lasts for decades.  It doesn't stay in the ocean either.  That oil washes up on the shores and destroys plant life, and an entire food chain for the region's wildlife.

Natural gas is the new green, as far as energy goes.  It burns cleaner, and is supposed to be better for the environment, but is it really?  You hear a lot of noise about how it poisons aquifers and things like that.  I think that is because they use hot water, sand, and toxic chemicals to open the shale, but if it is done correctly, that will be sealed in, and unable to reach the aquifer.  The real danger here is the fluids that come back up during the hydrofracturing process.  In many states that lack a long history of oil production, an operator can dump that waste wherever they want, because there are no regulations on how they must dispose of it.  That is the biggest environmental danger to hydro fracking.

There is some evidence that hydro fraction will cause small earthquakes.  Although unsettling, these earthquakes have not been large enough to cause any serious damage.

Now before you go jumping on the natural gas bandwagon too, remember that this is not a solution.  Like any other fossil fuel, the supply is finite.  Think of this as more of a ten year band aid, because at best, that is what it would be.

Economic Factors

The bottom line is everything in our economy is dependent on one fossil fuel or another.  Production requires electricity of some sort, even if it is just to keep the lights on.  The raw materials used derive from a fossil fuel are found in thousands of household items, or in the case of steel and iron, vital to its production.  And the transportation of goods always requires oil.

Fossil fuels control the means of production, and as such, have a complete stranglehold on our economy.  If any one of the fossil fuels supply is threatened, you will see a change in production.  Production is not controlled by an agency, like we have been led to believe, but by the amount of resources available to us.  Until we realize that the world is finite, and as such, infinite growth in a finite world is a ridiculous idea, we are dancing with danger.  We need a new approach, and we need to be prepared for the damage we have already done.  Melting ice caps and steadily increasing temperatures are not things to be ignored.

But, in order to address these issues, we need to change our approach to money and the economy that is driven by it.  We need to move away from this consumeristic economy, where we just take and take and take, trying to keep up with the Joneses.  We are all trying to get the largest part of the pie.  We feel entitled to it, when really we are only entitled to what we need, because that is what everyone else needs too.  Only by living with only what we need, sacrificing unnecessary luxuries, like Escalades and Swiss bank accounts, and expanding the very simple luxuries, like indoor plumbing, water that likely won't infect you with a virus, and a food supply, will we really understand how to live in harmony with the Earth.

Next month, we will talk about what this means for future generations, and the problems they will face if we don't turn our thinking toward cleaner and sustainable energy sources.  We will also discuss how viable each are, and what fossil fuel it could help to replace.

Peace and Love,

Luci

The Economy, Energy Consumption, and Upcycling: Putting the Pieces Together

The Economy.  You can't open a newspaper or a news site on the internet without seeing something about the economy.  It is all anyone can talk about.  Being an election year, politics tends to bring these things to the front page, but we are going to leave politics out of this.  This will be a discussion of the core issues.    We will discuss how energy has a direct affect on our economy, how energy consumption factors into this equation, and raise the question of what effect upcycling could have.  In later articles, we will go into much greater detail in all of these areas, but for today we will focus on the basics to get the conversation started.

For the first article of this series, I thought we should spend our time making connections.  The mainstream media is terrible at making these connections.  It does more to confuse people than it does to help them understand how hydrocarbon energy and our economy go hand in hand, probably because all of our media outlets are owned by only 6 corporations, but that is a different conversation.  That's okay though.  We don't need them.  We can make these connections ourselves.

The Connection between Hydrocarbon Energy and the Economy:

Our economy is built on consumerism, which means that, at its peak, 70% of our economy was built on people purchasing goods.  So what does hydrocarbon energy, or oil, have to do with this?  Everything.  The US Energy Information Administration tells us that out of one 42 gallon barrel of oil, only 19 gallons of it is used to produce gasoline.  So what are the other 23 gallons used for?  You can find some wonderful graphs and explanations here on this post on the Oil Drum, done by Chris Skrewbowski.  Only a small percentage of oil or natural gas produced is currently used to manufacture everyday items.  So why is this small percentage important?

First, let's look at the goods we are purchasing.  Thousands of goods are petroleum based.  Literally thousands.  You can download a good list here.  I don't have the room to list them, but I guarantee you are using one of them right now.  A substantial portion of the goods we purchase are petroleum based because it is a cheap material source, and allows for more people to afford to purchase the various goods made with it.  With an economy that is fed by consumerism, the ability for more people to be able to purchase is vital to our financial "health".  This also creates other problems, like cyclical consumerism, which means that products are designed to have a short life span so the consumer needs to go purchase a new one sooner, but that is a lengthy discussion that will have its own article later.

Second, transportation.  This is where the vast majority of oil is used and it is transportation where it is truly difficult to substitute for oil.  We live in a global economy.  Most goods are not produced locally, which means that large amounts of oil are required to transport those goods from the manufacturing plant to the stores that will sell it.  Now, that may only be a state away or it could be an ocean away.  Most likely, it is an ocean away.  Transportation of goods is vital to our economy and our food supply.  If these goods do not make it to stores, consumers are not able to purchase them and contribute to spending the 70% of our GDP our economy once boasted.  In a worst case scenario of transportation failure, food wouldn't make it to the grocery store, and people would soon be cut off from food sources.  Starvation would become a serious concern.



As you can see, hydrocarbon energy is so entrenched in our current system that there are no easy answers.  This is a complicated conversation we are having, but that doesn't make it impossible or even difficult to understand.  Once you know the basics, the rest is really easy to follow.  Once you know that all of the items you purchase are either made from hydrocarbon sources or transported to you using oil, you can see how fossil fuels shape everything you have and need, including access to food.  This is why, although we have a consumeristic economic system (meaning simply that our economy is driven by people spending money), this system absolutely depends on hydrocarbon energy and cannot survive without it in its current structure.

What About Energy Conservation?

This is an important question.  We can certainly be conserving more energy than we are now.  It is obvious that there are some people/corporations that would oppose a large movement to conserve fossil fuels because it would hurt their bottom line.  It doesn't matter that their combined bottom line is trillions of dollars and they could lose a few billion and still be able to feed their families and live in a nice home and take fabulous vacations and do whatever else is important to them, but that isn't how our system works right now.  But that doesn't mean it needs to remain that way.  

It should be remembered that sustainable energy is a finite resource.  We can only collect so much energy from the sun and wind and tides, and we may not be able to harvest enough of it to replace fossil fuels at our current rate of consumption.  To make sustainable energy a realistic goal, energy conservation is essential, and even then it likely won't be enough right away.  This is important to realize.  We can drastically reduce our dependency on fossil fuels, but we lack the necessary infrastructure to immediately eliminate them. It will take time to build this infrastructure out--and time is something we are running short on.  





We all know that we need to conserve energy.  So what do we do about it?  We could all use mass transit, or make a donation to our favorite non profit environmental group, volunteer to help clean up an environmental disaster, or live in passive houses.  All are great ideas, but are they enough?  Shouldn't we be demanding large scale sustainable energy efforts?  Of course we should (and many of us are), but there is an idea that has been planted in the minds of millions that this infrastructure would take too much money to build out.  Some people only look at the price tag and can't see the return on the investment.  The question of what obstacles need to be overcome to achieve large scale sustainable energy, and what we can do ourselves without government assistance, should be explored.  This is also something we will delve into greater detail in a future article, which will also include more conversation regarding the alternative energy sources available to us and how viable they are.

What About Upcycling?

We all know that upcycling on a small scale, like the way us hard-working artisans go about it, requires very little energy.  There are very little in the way of manufacturing processes in our work.  We lovingly create from the item as it is, with most alterations to it completed with our own two hands, or in some cases a sewing machine or machinery to cut or shape wood and metal.  All of these require very little energy compared to mass manufacturing.  We may cut or reshape the item we are working with, but there is not an energy sucking recycling process that takes place.  Large scale upcycling would take on a recycling process and that requires a lot of energy.  Remember that no where in the definition of upcycling does it say that a manufacturing process does not take place.  It only says that the item is not inferior in quality afterward, as it is in recycling, or downcycling, as it is now often being referred to.  

We need to make a distinction between Industrial Upcycling and Artisanal Upcycling because they do not and can not operate in the same way.  Industrial Upcycing would likely be too large scale to be successfully accomplished employing the small scale methods that Artisanal Upcycling uses.  The question becomes what kind of energy is being used to accomplish Industrial Upcycling.  This really goes back to energy conservation and alternative energy resources.  It is easy to have an immediate impulse to reject Industrial Upcycling because of the manufacturing process.  I myself had a difficult time coming to peace with the idea, but the bottom line is that it is the best option we have.  Especially when it comes to things like e-waste and metals.  The recycling process is always dirty because it requires so much energy, but compared to mining practices and the toxic nature of e-waste it is a preferable alternative to traditional methods.


The energy could easily be cut in Industrial Upcycling if companies incorporated upcycling successfully into their business models.  It is happening right now.  Companies like Terracycle and Hipcycle.com have built their entire business models around upcycling.  I have never hid my fondness for these companies, and their success can mean big things for upcycling.  These businesses are proving that upcycling can be a profitable business model.  Once something proves profitable, every company becomes more eager to incorporate the same methods into their business models.  I say the more the merrier!  Why they are doing it should matter.  They should want to do it because it is the environmentally responsible thing to do.  But at this point I can be quite content if they are doing it for profit, as long as they are doing it.

What Comes Next?


Obviously, we have only just scraped the surface of these issues.  As this series develops, we examine each of these issues and more.  We will get into the guts of all of it.  We will look at how we can incorporate sustainable energy sources into our current infrastructure, we will examine a resource based economy designed by Jacque Fresco (call me a "Utopianist"), we will look at what kind of infrastructure is needed for Industrial Upcycling, how Artisanal Upcycling methods can be employed by companies to maximize profits and reduce waste, we will talk about cyclical consumerism and what we can do to decrease it, and we will further examine how fossil fuels and hydrocarbon products drive our economy.  In my next article, we will really examine all the ways our economy is dependent on hydrocarbons.  This will be a detailed journey right into the belly of the beast, so to speak.  

I encourage comments and would love to see a productive conversation begin.  I only caution you to try to leave your politics out of it, as I have tried to spare you from mine.  It is difficult to leave politics out of it, as we depend on politicians to act on these kinds of things, but I implore you to leave your politics at the door when leaving comments.  Politics just clouds the core issues and we want to see the facts with perfectly clear vision.  There are no democrats, republicans, socialists, fascists, communists, independents, or any other political faction on this board.  There are only passionate humans with a common goal, leaving the Earth in better shape than we inherited it.

Love and Peace (with a special thank you to my wonderful boyfriend Dr. Loren Ballanti for helping me edit this article.),
