')In a declining energy environment, the last thing you need is a new energy consumer. Complex technology is just that--an energy consumer, with all of the by-products of energy transformation that we call pollution and waste. This takes even more energy in the long-run to deal with it than you gained from the short-term utliity. No free lunches. Cleaning up a mess creates an even bigger mess. Always will. 2nd law forces us to be always playing catch up.


So, the sun doenst give us buttloads of energy? We cant grow more biomass which stores the suns energy and consumes the carbon that burning the biomass produces? No matter how "green" the technology is we are Doomed Doomed Doomed Doomed Doomed all because of the dreaded Second Law of Thermodynamics?

Sounds the same as a cross cultist using some obscure passage from the bible to justify his view that the world ends next thursday afternnon at 5 PM.

Oh, I forget, since I dont understand "SCIENCE!!!" I am just not getting how VITAL this all is to our very SURVIVAL!

Got it, me moron, you genius. Me send you all me money to get you book on how me so screwed. Uggh.

The earth is an closed system receiving an energy flux from the sun.
Since Energy In > Energy Out, the earth is not in thermodynamic equilibrium, thereofre the order may increase on earth. There are limitations in the sense that if we had a way to appropriate ALL the energy received by the sun for "economic growth" there would be no energy left to run the climate, grow plants or even maintain the atmosphere (it is maintained by plant life).
Since you want to read on the thermodynamic limits of sustainability I would suggest the following article: http://engineering.dartmouth.edu/~cushm ... bility.pdf

Never said it didn't. That is not the issue. The issue is that right now, and for the forseebale future, the energy source that holds entropy at bay is ancient sunlight in the form of fossil fuels.

We have only harnessed 1000th of 1% of the solar flux so far. To create complex technologies that rely on cheap abundant energy to keep entropy at bay in a declining energy environment, is asking for chaos.

We need to use simpler, less energy intensive technologies that are sustainable and low-entropy. We need to use less energy, not more.

And no, we are not doomed, we just need to consider that our sense of order is the exact opposite of the way the world works and proceed acccordingly.

Our idea of using technology as a short-term utility to solve a problem actually increases the problem long-term. There are no free lunches. Water does not flow uphill.

We are always playing catch up as 2nd law prevents an even exchange.

the problem is that most of the laws of physics are flawed because in order to observe something it is necessary to assume some fixed point of reference which in reality does not exist.

the cat, mouse and bag of peants locked in a box for example does not take into account that fact that it is on the earth spinning at about 700mph. which itself is spinning around the sun, which itself is flying about inside the galaxay etc etc.

the problems become much more obvious when you look into cosmology and astrophysics. Scientists have had to come up with all kinds of unknown objects to account for the lack of sufficient gravitation forces to hold the universe / galaxy together. Even Einstein was concerned about the possible invalidty of the black hole implications of his theories.

physicists have over looked the plasma / electrostatic models that show much more accurately how galxaies interact with each other and how they function internally, without the need for a whole plathora of unknown dark entities that cannot be proven to exist.

The current argument in astrophysics is that it is assumed that dark entities must exist and no one can prove they don't, therefore they must exist is a completely non scientific theory, equivalent of me saying that garden gnomes exist unless you can prove they don't.

Where does all the energy to power the spinning solar system and galaxy come from ? How is it held together, there must be a hidden energy source, therefore I would say using the current daft science that hidden energy sources must exist unless you can prove they don't. It all gets silly. Science is stuck in a dogma because the old school refuse to move on past old theroies that are over simplified at best.

For a detailed dicussion of this see the following link.

http://www.electric-cosmos.org/introduction.htm

It is much more likely that the galaxies are held together with electorstatic / plamsa forces that are much more powerful over long distances than gravity. Therefore if you can tap that energy source you can enable a vast energy producing machine with a small amount of energy. I believe that some of the "loopy inventions" that can't be understood with standard physics are doing this.

And like I said on the other forum, just because a caveman had no idea of why firewood burned and the chemical and physical processes taking place, didn't stop him from heating his cave and cooking his food.

Infact the entire industrial revolution took place with very little understanding of the electro-molecular operations of burning things, but that doesn't mean they were useless or invalid.

$this->bbcode_second_pass_quote('Raphael', 'I') also believe the process of moving from a state of minimum entropy (the past) to a state of maximum entropy (the future) is the template used in the many different stories contained within myth.


Since it is such an ubiquitous law, it is no surprise you will find it in many myths.

One problem with looking at peak oil from an entropy point of view is that producing entropy is so much fun:

Eating chocolate,: oh all that lovely entropy.
Downhill skiing: glorious entropy.
Sex: hot and sweaty entropy!

You don't need to bring thermodynamics into a discussion of peak oil. Calling oil a "finite resource" is perfectly adequate. Talking about entropy adds nothing, and probably puts off many people.

I think the entropy discussion is important. In practical terms, I agree that the idea of depletable resources and EROEI is more to the point. The only issue I raise with the entropy discussion is that, once it has been addressed, it tells us nothing about the response of industrial society to energy depletion. But entropy and more generally the thermodynamic perspective does help people understand that there are limits.

Just like I think the exponential growth and overshoot concepts are very important. The might turn people off, but I think they are a foundation for any consideration of ecological economics and human ecology.

Where I get tweaked is when entropy and die-off are used to motivate any detailed understanding of how energy depletion will play out. The response of industrial civilization is unknown. The timing is unknown. History provides clues but cannot be used to prove much of anything, both in terms of human behaviors or other matters.

Hence I get tweaked when Katrina is used as an example for the response of industrial society to peak oil Katrina indicate the response of industrial society to the loss of a coastline due to category 4/5 hurricanes. Beyond that, it proves nothing. Neither does entropy. Nor overshoot.

I used the example the other day on a different board of not ever seeing SUVs in a test tube. If you look at many discussions of peak oil, e.g. Savinar's book, the idea of bacteria and other animals are used. What these comparisons do not take into account is that most animals are highly optimized to the energy in their environment. Once the energy source runs out for those bacteria, they don't have a lot of options. Humans have more options. And humans are not bacteria.

Hence my other rant. The "humans are shit" rant in another thread was primarily motivated by the gross analogies that are often made, comparing humans to bacteria. Now I sometimes have a rather negative--and perhaps realistic--view of what humans are capable of--but they are not bacteria. Animals yes, but that does not provide me with predictive power.

Humans waste enormous quantities of energy. Because it has been dirt cheap. Bacteria don't. That doesn't mean we don't have problems. But the waste must be taken into account. The reduction of waste means loss of jobs, society slowing down, or many things. It's not necessarily hopelessly hopeless, nor hopelessly optimistic. Perhaps there is a path through the bottleneck. Entropy tells me nothing about the existence or non-existnce of that path. In the interim term. In the next five years. Or ten. Or twenty. Or thirty.

It is the response of industrial society to energy depletion that is the primary issue. And entropy, overshoot, and the derision of human nature only provide a very coarse understanding of what will happen. In the long term, entropy does indicate that--well, that everything sort of runs down. Planets, stars, universes--perhaps the latter, still not completely understood.

The key question is the response. And this is also why I still question efforts to create depletion curves. The world has never depleted energy on a global scale. The depletions we've seen to date have been local. Those global depletions are geoligical-economic-political. There is enough slop and noise that I think trying to fine tune depletion curves to mean anything in the future will prove futil. In addition, the response of the consumer--industrial society--must be taken into account. And we don't know that response.

Hence I bring up the issue of emergent systems. Cities, industrial society, etc is a complex system and the study of previous collapses is interesting but not predictive.

Therefore, I think the issues of overshoot, entropy, limits, are all important but, once understood, can be set aside. Because the reality is industrial society and political systems and the behavior of humans, both collectively and individually, are key.

More broadly--since I'm obviously pontificating now--one has to wonder whether this is the natural outcome of any evolutionary process in which a creature rises out of the muck and, at some point, discovers the means to tap into low entropy sources. Everyone discusses how great the Native Americans were, how they had a sustainable lifestyle. In some ways. But there are a lot of large land mammals that may--and it still seems to be may--have been driven to extinction when they crossed the land bridge.

So then I get to wondering: what should be the individual response to peak oil? Is it to go to whatever extremes are necessary to save my sorry ass? Isn't that part of the problem? That we're all so concerned about ourselves? Remember the entropy argument. Everything runs down. So whether it happens slowly, or quickly, it will happen. To a degree, that completely negates the argument of those who use entropy to argue that humans should slow down. Why? If it's going to run down--and it will, someday, since the sun will run down--is it so bad to go out in a big bang. Why wait?

Now I don't seriously believe that. I'm all for society slowing down. But the entropy argument is a double edge sword.

So then I start wondering: ok, all those concerned about saving themselves, they're actually part of the problem. Because they're only interest in this whole topic is to save their ass? Yes, a straw man. Not true. But a perspective to consider.

See, from one perspective, I wonder whether the real response to peak oil, for the committed environmentalists, should be to "off" themselves, i.e. suicide. And please please note I'm not proposing this. This is a philosophical speculative rant. But if they are that concerned, shouldn't they set the best example one can of saving entropy. "News flash: Members of industrial society "off" themselves in order to reduce increase of entropy."

Here's the deal. We don't know the following. When the peak will occur. What the depletion curve will be like. What the response of industrial society will be like. How long it will play out. What effiencies will be found. What restructing will be performed. All uncertainties.

Entropy is a cool concept. But it won't answer any of the above questions. At least not enough to tell me about the following 30 years. The only thing I am certain of is that there will be energy shocks.

All things have their time. Someday the universe will end and civilization with it, the latter most likely sooner than the former. Oil may be a finite resource, it is nevertheless a resource. It would be as much a waste not to exploit and consume it for the purpose of civilization as it would be to consume it too rapidly. Should we have left the oil in the ground such that it can witness the end of the Earth having never been disturbed? Then it will have missed its role in the great project of civilization for which it was destined.

A middle ground must be found. Oil will come out and it will be depleted. All that we must resolve is what will be done with the oil, and where civilization will proceed after it is no longer oil-based.

“Destined”, to me, implies something religious which causes my gag reflexes to go bonkers, but nonetheless, we are special, or if you prefer, gifted. The problem is we aren't so special as to toss aside all other life forms on this planet as being not special. There needs to be a better balance or else ultimately our special little asses will pay for it. “With great power comes great responsibility”.

We could have done a much better job of properly utilizing oil from the get-go. But when we discovered oil our main concern wasn’t, “gee we better make sure we use this properly so that in 100-200 years for now we don’t regret it”. “It was how do we use this stuff to make our lives better?” Hindsight is 20-20… the energy problems in our future will make that pretty evident to all. Hopefully we’ll have the opportunity to learn from it.

I agree. And the middle ground, whatever it means in practice, will only be found when energy becomes much more dear and expensive. I've been reading Douglas Reynolds lately, an energy economist who has been writing and warning about depletion for years. [link]. He's got a few writings I've been looking at in particular: "The mineral economy: how prices and costs can falsely signal decreasing scarcity";' "Energy grades and historic economic growth;" and I just ordered a copy of his book "Scarcity and Growth Considering Oil and Energy: An Alternative Neo-Classical View."

I would suggest that the vast majority of the world's population survives for weeks on end without ever actually "thinking".

Repeating the same schedule as the previous week, week in, week out, going to work, coming home, eating, sleeping following the routine, all of this can be done without ever actually "thinking".

Here I am not classing gut-reaction, intuition and following a routine as "thinking".

In my opinion, energy is built up in the universe from zero point energy. The uncertainty principle reveals that the ground state of energy in a quantum system is never exactly zero. It is constantly changing. The universe is filled with constantly fluctuating low levels of energy.

Remembering that matter is only a form of energy, it could be created by zero point energy stacking itself together over time. Take it only as a hypothesis, so don't accuse me of saying that we can turn zero point energy into power and save the demise of the hydrocarbon age.

Not really. Your article seems to be an mistinterpretation/simplification of how entropy works. Isn't is probable for sub-systems within a closed system to decrease in entropy if sufficient energy is available (like that we get from the sun, the earth's core etc)? How much are humans increasing entropy? Faster than if we weren't here? What's the main focus of this site?

Seems unlikely. As far as I understand it, you must also concider that quantum fluctuations also produce negative energy. So there's kind of an evening out over the universe. I believe the first law of thermodynamics remains unchallenged.
