Errors in Efficiency - notes & discussion of the growth effect and other things
Like some of my other web pages this is a collection of current and older work, check the dates

Generally speaking, the hard clear data says is it's because:
-- Every business is competing to be more efficient to not fall behind the competition, all the time.
-- Improving the efficiency of something by, say, 50% could increase its power to do work 200%... 
-- on average the economy turns a 50% resource use reduction into a 75% increase, a 250% reversal
("Jeavons' effect" might reduce the effect of a 50% efficiency to 40%, not the same thing as the growth effect )

10/19/09 11/15 It's not a mistake to want to be efficient in using the earth.   It's only a mistake to think that being creatively efficient in growing the economy all along wasn't what got us to this impasse.   Our being more efficient still mainly makes the economy grow more efficiently, which multiplies our impacts on the earth.    Very unfortunately, continual impact growth is one of the unintended true effects of most of our sustainability strategies.   A sufficient reason why is as a consequence of convenient linear thinking, instead of really looking at the total effects of things.   The fact is making a growth system more efficient accelerates it.   It always did.  It also always will until we think things through and change how our surpluses, both physical and financial, are used to continually multiply our uses of the earth.   The essential change is actually fairly simple to define, for everyone to wisely use their investment returns for something other than multiplying investment returns, but there are lots of things to learn about that on the way to making it real.  

If our main solutions have become our main problems, the usual way of solving things is what needs to be rethought.  
The usual fix, more investment and willing hard work, won't heal our relationship with the earth.

To change may have to start with learning how we got so confused in the first place  Phil Henshaw   contact

Our amazing mistake…    misunderstanding efficiency        

11/18/09 We try hard to reduce the impacts of doing our tasks, And miss their added impact in improving the service. Our blind spot is how efficiency is used as a tool, used to facilitate other work & services.  It removes barriers and resistance in the economy, mainly profiting from enabling the growing parts.

1)    Everyone promotes reducing our impacts, but it only pays if it multiplies our services…,  It’s the leverage of creative problem solving, small smart costs with big effect, that so multiplies our impacts. 

2)    The sustainability and environmental movement leaders, along with the business, government, science, and education communities, wish  efficiency reduced our impacts on the earth in total, not seeing why it always did more of the opposite, accelerating the conflicts we’re trying to reverse.

3)     Efficiency & productivity always removed barriers to growth and increased our impacts.  it seemed to only have benefits until we started colliding with our natural limits, before about 1960.    . 

4)    What apparently happened is, without really thinking, popular culture chose reinforcing our work ethic as a solution, instead of looking at why our work ethic produce the problems we have to start with.

5)    The smooth curves indicate ‘liquidity’ as markets equalize price and supply changes.  New efficiencies one place set new standards and relieve demand in every other place, for example.

We need a new agenda. 
Could it be to switch from providing ever more service to taking ownership of the whole product?


The problem with our concept of I = P • A • T is that it's missing the hidden 'S' for growth Stimulus 

Impacts on the earth = Population • Affluence • Technology efficiency • Stimulus of increasing productivity

It's 150 year old established science, actually.   Why we use efficiencies is to simplify our tasks and become more affluent.   Our main purpose in improving organization and being more efficient with our tasks, often with improved technology, is to increase our productivity.   That's a growth stimulus.    That makes using it as a strategy for reducing impacts completely self-defeating.   Over a century ago Stanley Jevons noticed the effect in England when improving steam engines to use less coal accelerated the consumption of coal, not the reverse.   The added utility and growth stimulus of improved technology, and so the productivity of the people using it, increased the use of the resources it was intended to conserve.   

 

It was called "Jevons' paradox" because it is counter intuitive.   It's been widely discussed too.  People have simply not applied it to correcting our wishful thinking when it comes to saving the planet from our overconsumption...    Though long recognized by many scientists, even other scientist don't take it to heart, so it's been completely ignored in the public advocacy for sustainability by educators, activists, media and government in organizing, planning and research.    That's trouble!   It happened partly because people normally think by snap judgments, and "go with their intuition".   Here our intuition is dead wrong.    Somehow even modern economists have just never seemed to mention that as a strategy for impact reduction it fails entirely.   Someone needs to research the full story of the confusion.   It's both important intellectual history and critical for getting to the bottom of why we let our main solution for relieving our impacts on the earth be a direct multiplier of the very problem it was intended to address.

 
Sustainability does need efficiency, just not for stimulating even more growth.  It sadly does mean that the central tenet of sustainability that people around the world are now  relying on has the opposite of the intended effect on our environmental.   Look at the language of the proposals.   Even the strategies for climate change to reduce CO2 and other GHG emissions are entirely phrased as plans to improve the efficiency of growth.  Then look at the curve.   It only means money growing faster than impacts.  Ot assures that all our kinds of impacts will keep increasing ever faster too, even if marginally slower than the money someone is making off them.   The only way to stop adding to our impacts is to stop adding to the economy, really.   That means investors accepting their natural fiduciary responsibility for choosing what systems the economy will develop.  They'd need to actually use their profits from investments to no longer undermine the value of our common investment in the earth, and invest in long term sustainability instead.    That's possible, but means that a fundamental change in the design in the economic system is needed to make sustainability physically feasible.   

 


One Amazing Mistake!

10/01/09 There are several mortal errors in using efficiency to sustain growth... making it a grave but fascinating error made by virtually all the world's leaders promoting sustainability:

•  it multiplies resource uses
• 
eliminates diversity
•  increases dependency on temporary solutions
•  delays the turn toward sustainability

10/1/09 Despite fairly widely understood economic principles, many leaders around the world thought that improving efficiency would reduce our economic impacts on the earth.    Now the whole world is trying to reduce our impacts with it, though it has the opposite effect.   The true effect of investing in profitable efficiencies has always mostly been to multiply resource uses and other economic impacts.    The people who saw that it as a solution were thinking the effect would be linear and deterministic.  The economy is non-linear and opportunistic.  The bottom line is that, instead of being rigorous, thorough and truthful they went with ideas that were simple, appealing and profitable.  They put choosing a model that would be easy to sell ahead of getting it right.   The earth was "too important" not to have a solution that was easy to sell... is what many people told me over and over.   I'm a physicist and architect, and both teach you if you'll need to rely on it, it's always better to get it right.

Efficiency is economic stimulus, and using it to reduce our impacts seems to steer us straight into the calamity it was intended to steer us out of.   It makes our solution the main problem we have.   There's a hidden dimension that can snatch success from the jaws of defeat, though, that the solution that so many feel is intuitively right is only dead wrong and self-defeating when used for perpetuating growth, as we are now doing.      Our economic system is built and managed to be a perpetual growth system, so promoting efficiency now just speeds that up, promoting ever more rapid consumption of every affordable resource on earth.   That's the problem.   Efficiency reduces resistance for whatever it its applied to, though, so it could be applied to something else instead like maturing the system instead of growing it if its growth imperative were removed. 

I've been pointing out different sides of this, one after the other, for several years now.   Trying to point to the genuine greater profit in "doing it right" was a classic "hard sell" though, because would mean thinking it through with where it would lead not apparent to people who just glanced at the proofs and pushed them away.   

The analytical error was thinking that the economy would respond as a linear system, as represented in the commonly used expression:  I=P*A*T   What that promotes is selling technology, saying:   Impacts can be reduced if Technology is improved faster than Affluence and Population increase.   The error is forgetting that improving technology multiplies affluence and population. It was an easy sell, though, because it was profitable and fun.   It also just seemed 'intuitive' that doing more with less would mean using less, even though it never had before and for centuries business people used it to leverage doing and consuming ever more.   The trick is that doing more with less is about using less of one thing for the purpose of doing more of other things.    Our normal choice to use inventions to do that when the leverage is greater than 1.    What other things get stimulated tend to be ignored or come from what other things happen because of the money or energy being saved, or how the innovations involved spread.   Our economy is a self-investment growth system, using as much of it's products to multiply its process as it can, and so that is what any real surpluses tend to become picked up and used for. 

 Fig. 1 - World energy use and energy productivity trends

Figure 1 is (see note box above) the convincing authoritative data, the IEA global data for fuel use and the global economy's efficiency in turning it into wealth.     it shows that improving efficiency of energy use is the larger part of GDP growth, but driving continual rapid energy use growth as well.

Think of what the money saved gets spent on or invested in.   Think of the expansion of previously uneconomic things that can now be done with the saved energy or using less energy.   Think of how businesses target the key efficiencies that remove bottlenecks for expanding the use of *other* resources.  

An easy example is water saving appliances that lets you build larger housing  subdivisions within the regulations.  There ends up being no reduction of stress on the water supply because the number of users increases to meet the maximum water use anyway.   Plus you get all the other impacts of building and occupying more houses….   In addition, and maybe the worst one, is the false psychological effect, of making people think they are cutting impacts when increasing them and the profits of that that go to doing more.   

These kinds of complex feedbacks are just what are always found in growing complex systems.   Growth is actually an opportunistic rather than a deterministic process, so that's the real reason that the deterministic causes are untraceable.   They emerge and vanish repeatedly as the active agents of the system discover and take advantage of their opportunities.  What I discovered is that they're a little more traceable if you are working backward from already knowing the total.   It's easier to find the unknowns if you're task is to divide up a known quantity rather than add up unknown ones.   In accounting for complex systems if you only add up the effects you can trace you're nearly certain to miss most of them!  

The usual "rebound effect" that sustainability leaders consider is called "Jevon’s effect".  That's the effect caused by reducing demand for a resource being conserved which also somewhat reduces the price, and so reduces how much demand declines.   That local traceable effect is usually found to dissipate, i.e. to be a small factor that reduces the amount of direct resource savings.   It doesn't consider what uses of other resources are increased as a result, or what other things are done with the saved costs or whether and how the innovation spreads and multiplies in a viral manner as many do.   So, Jevons' effect  doesn’t show the multiplying rebound effects that are evident, as above, in the measures of the economy as a whole. 

 So…. don't use I=P*A*T , because P*A (= GDP) seems clearly dependent on T.     Sometimes I get the arithmetic wrong, and should review this further, and it bears confirmation by others too.    For the past 30 years in our growth economy, in any case, one should have assumed that any efficiency would have the average reverse effect.   There may or may not be good ways to estimate how far above or below average the effects of any particular efficiency improvement would really be.  At this point it appears that the average effect is that energy uses increase 1.7 times the improvement in energy productivity, d(E)/(E) = 1.7*d(P)/P.

It means that the sustainability thinkers were less careful in looking for what was truthful than what was profitable… unfortunately.   The strategy picked, multiplying technology, is good at making money certainly, but when applied to speeding growth is also good at multiplying impacts.   It's how we got here.    It's critical that there be no delay in finding a better plan!    

I guess you could say the popular solution has made us into our own worst enemy.    We were clearly “thinking locally and acting globally” using a "good feeling" strategy chosen to be appealing and profitable.   I only noticed it because I already knew the cure, to switch the system as a whole from growth to maturation, using how nature does it as a guide.     I'd been trying to figure out why no one would listen to what would actually work.   There's both near and lasting profit in it.     Switching the economy to mature within its limits would effectively mean declaring an end to our very expensive "war with nature".     The trick needed to shift the resources used now use for ever  shorter term profits to funding the long term efficiencies a non-growing system needs results in a big "peace dividend".    It would be surprisingly profitable, too for long term investments in particular.  It would also be somewhat of a culture shock have free markets in which "prudent" meant "lasting" investments and quality rather than quantity returns...    Various aspects of how we could copy the way natural systems do that are in much of my writing, like: Economies That Become Part of Nature.

Accelerating our use of shrinking resources
 without building a sustainable society.


As efficiency & productivity improvement drive economic  growth & impacts

9/17/09 In natural systems "doing more with less" has two faces, opening up ways to multiply things, opening ways to complete and perfect them.   We are using up our cheap non-resources on multiplying our systems, and so will run our of resources for completing, perfecting and making them sustainable.   All kinds of lasting systems begin with multiplying their parts, but then mature by perfecting them.   It's the pattern you see in both building designs as well as in building buildings themselves, starting like any project with successively bigger parts followed by successively smaller ones as you complete and perfect the project as a whole.   Efficiencies at every step facilitate whichever direction the whole system is taking...  Our economic problem is our failure to switch directions, from using surpluses to expand our systems on the earth to completing and perfecting them, and so as all our solutions are coming into conflict, technology improvement isn't the solution, but really serves to multiply the problems and intensify the conflicts instead.  

So... thinking that sustainable design should be used for completing and perfecting our use of the earth doesn't result in that.  Creative efficiencies either create the opportunity for one or the other whole system response.   It's the whole system response that determines the accumulative effect, which now is to use efficiencies intended for sustainability as a sneaky new resource for sustaining the multiplying impacts of the old endless growth plan instead.    Understanding how and why that happens requires a little 'free thinking' about how the lasting effects of any one thing come from the uncontrolled opportunities they create for others things in the future.  

Our whole culture largely thinks what determines events in the future as being chains of deterministic causes.  It leaves us rather blind to the main pathway nature uses for creating self-animating whole systems,  chains of opportunity.  Wastes become resources, what's "given away" and abandoned becomes the key to what connects you with other things.   Nature thrives on "free stuff" too!!   What, for example, happens if you invent a car that uses half the gas?   It  very profitable and you get a bonus.    The company sells a lot more cars for one thing, and a lot more miles are driven, and if any money or fuel is saved it supplies the expansion of other things, and the saved profits go to the bank to multiply more businesses making other very profitable innovations.   The accumulative effect is that it doesn't reduce impacts on the earth but multiplies them.    That is the accumulative opportunistic effect of liberating resources in an economy using all its surpluses to expand its systems.    For the whole economy to switch from that way of using efficiencies to the other requires discovering why trusted way of using solutions to multiply solutions has become our main problem.     Why did it?   The environment changed when getting bigger and bigger resulted in our getting "big", changing all our relationships, and reversing a great many of the rules of profit...  So to discover how to use efficiencies to perfect our relationship with the earth, and lighten our burden, requires rethinking the whole relationship...!  Start with thinking through the ways we already know so well, of completing and perfecting things as the key to going on to do others.


04/15/09 05/20 Efficiency and productivity enhancements are the main strategies promoted for advancing sustainability, but because they stimulate expanding uses more than reduced inputs, they generally have the effect of stimulating growth and of multiplying strains on the environment.    It did once seem to work the other way, but that was before we started to run into natural limits, but now it creates scarcity rather than plenty, and so multiplies conflicts instead of solutions... 

The main reason is that efficiency and productivity (two words for the same thing) are the primary means used by businesses and individuals for price/value competition to gain advantage over each other in the marketplace and stimulate their own growth.    "Delivering more for less" gives you increasing leverage.   It serves to *lower the burdens on the user*, so they can *increased their their burdens elsewhere*.   Because this is the primary means the sustainability movement has adopted for reducing our impacts on the earth, we have lost very precious time in finding the right approach to saving the planet from multiplying human impacts.   It appears that we have all been mistaking the effect efficiency has on us for the effect it has on our world, and they're completely opposite.   That's a clear enough error to create a "learning moment" though.

We have lost very precious time in finding the right approach to saving the planet from multiplying human impacts.

Take the simple example, a person learning to prepare their own food more efficiently, and so needing to buy less.   It means you get the same benefit from less expense... and have suddenly created wealth out of thin air and have more money to spend on other things instead.    It also reduces your demand on the food supplies so other people can buy more for lower prices.   If you don't spend it and put it in the bank instead, then that money "goes to work for you" creating more efficient technology so other businesses can grow.   

The complicated question is what determines whether these circles of effects either multiply, stabilize or contract.    Throughout economic history they have multiplied, but steady state economies are both possible and necessary to discover how to create.   Ideally economies would grow and stabilize like the cells of your body do, at the peak of their vitality and the beginning of the prime of your life.   Our growth system accidentally emulates natural systems for which the cells grow to peak and collapse in exhaustion instead, pushing the limits till there's no were to go.

You can classify the "rebounds" of efficiency and productivity improvements as "micro" effects and "macro" effects, and discover them by tracing through what happens with the resources "saved".    An economy works as a whole and everything that changes use one place changes value elsewhere, and so acts as a whole in response to any change whether you see it or ask for it or not.   That's the tricky part.     So, resources saved get used for something else!    If you save time in the kitchen, you have time to more of something else, simple as that, and that changes your relationships with everyone else.    

If you make cars that use half the gas, the available fuel would then let you have twice the cars, and the same dependency on foreign oil!    The problem is with the plan to push the limits, using any efficiency to maximize your increasing use of the earth rather than reduce your uses.    Were we've taken that is to where our resource uses, and other interests are all coming into conflict!    Increasing productivity saves some resource locally, but in our culture that is used to multiply what we do globally.  That's the problem.  Conserving locally ends up multiplying waste and conflicting needs globally.   It's an even bigger problem that we're relying on it as our primary sustainability strategy, and won't be solved without thinking it all the way through.

In a growth environment having everyone become more productive and efficient is what promotes growth, as it always did.  "Green design" is just improved technology with a new name.    With the global plan to always push the limits no global relief of the limits results.   Locally as you relieve pressure on one thing you remove constraints on using it.   For a business, reducing unit costs is done in order to multiply the units produced, though, increasing rather than decreasing its total impact on the earth.   That's what the curves all show, steadily improving technique with steadily multiplying impacts.  One of those is improving our techniques for protecting human lives and welfare, that increase population and the growing spiraling cost of resources for supporting people in the style they would like. 

We're not confronting the real moral questions with that, and have not been adding up the totals.    Our desire to be ever more 'productive', defining "good" as "more", is exactly how we got in our present crisis of dependency on high consumption and multiplying impacts.   What we need is a complete switch from being "takers" to becoming "healers", but it's tricky to understand how, so we need to think it through.   It's NOT so much a question of reducing your 'waste'.   It's finding a way to relieve the urge for growth rather than satisfy it.   We need a change of purpose in how we spend the savings that efficiencies and productivity create, understanding true effects, to find choices with our intended effect.

Using efficiency for growth is likely a more urgent and larger hidden threat than global warming, actually, driving our overhead costs up and our remaining resource quality down, threatening a lasting collapse of our lifestyle, the opposite of our purpose.   As our efficiency and productivity have improved it has been increasing our energy use nearly twice as fast.   It's a profound error to think efficiencies in a growth system will reduce impacts, but it's nearly everyone's central sustainability plan.

How to tell if a particular efficiency has this rebound effect is partly whether it's profitable.  The "macro rebound effect" occurs by saving one thing to remove bottlenecks to profitability in using other things, having the net effect of causing those other things to multiply.   Efficiencies that save you money leave you more to spend on other things, so without cutting back you get to use more.    The solution is to make sure the impacts of your uses have your intended effect, figuring out how to use your taking for healing.    How to do it is a learning process we have yet to attend to, though, and starts with studying the problem and remembering details of the world we've been skipping over...  Your effect on the system is your ripple effect on others, so your way to change the loops is by changing the opportunity and signals offered to others, not by controlling their choices.   It's a different approach.

There are certainly positive aspects of simplicity too, and enjoying simple things is a natural part of healing, but to see how "pushing the limit" ends up multiplying conflict means going back to "book zero", and learning how the simplest growing things in nature manage the same problem with so little difficulty.   It's the growth oriented things that are also responsive to their neighbors that pass around the very simple wisdom that responsiveness creates independence, showing you what is free to take and stay out of trouble. 

For us the ripple effects of our money choices are global, not just on our neighbors, so it also means learning what happens to our money, where it comes from and goes to, so we can see what's free and avoid sending messages to take what will get us in trouble.   Efficiencies also have the negative effects of 1) replacing our own ways of working that are like ecologies with ones like machines,  2) replacing nature's ecosystems with our mono-cultures and so sacrificing her own diversity, resilience, capacity to learn, adapt and innovate, while  4) increasing our dependence on using up things that are running out and so sacrificing our own resilience and adaptability to change too.

The main unwanted reverse effects of efficiency & productivity 

04/15/09 05/20 Efficiency and productivity enhancements are the popular strategies for promoting sustainability, but generally have the opposite accumulative effect in fact because of how we use them.   It's both a "micro" and "macro" effect, of what we do with the resources "saved".  We spend them on something else!   If you make cars that use half the gas, "pushing to the limits" then gives you twice the cars, and the same dependency on foreign oil!   The problem is with the plan to push the limits, rather than hold back from them, because it actually ends up pushing all our interests into conflict!   That's why so many of our interests are coming into conflict.   Increasing the effectiveness of talents and techniques saves resources locally, but in our culture that is used to multiply what we do globally.  That's the problem.  Saving waste locally and ends up multiplying waste and complications globally.   It's an even bigger problem that we're relying on it as our primary sustainability strategy, and won't be solved without thinking it all the way through.
