Energy vs. Naturalist Wings of Environmentalist Movement--The Fight Begins

I told you so. The environmentalist boosters of biofuels and the nature conservationist wings of the environmentalist movement are now duking it out. A new report in Science (subscription required) magazine finds that conserving forests is a far more effective way to fight man-made global warming than biofuels. As The Guardian reports:

Increasing production of biofuels to combat climate change will release between two and nine times more carbon gases over the next 30 years than fossil fuels, according to the first comprehensive analysis of emissions from biofuels.

The environmentalist website Mongabay.com quotes one of the study's authors:

"For reducing carbon dioxide in the atmosphere, maintaining our forests and restoring them is much more effective than using land for biofuels," [Renton] Righelato told mongabay.com. "When forest is destroyed more CO2 is lost than can be saved in 50 years or more through producing biofuels on the cleared land."

Now Righelato may not be exactly dispassionate. He is, after all, the chairman of the board of trustees of the World Land Trust. However, he is right that current bioethanol technologies imply plowing up a lot of newly cleared land to produce fuel.

The New Scientist does note that cellulosic ethanol, that is, ethanol produced using non-food crops like trees and switch grass may be better than reforestation in reducing greenhouse gases in the atmosphere.

In any case, I did warn that current biofuels would chew up lots of land and that fact would provoke a fight between the naturalist and energy wings of the environmentalist movement.

The Science study concludes:

"For the longer term, carbon-free transport fuel technologies are needed to replace fossil hydrocarbons."

Maybe electricity produced by nuclear power plants and used by plug-in hybrid automobiles?

One thing about ethanol, cellulosic or otherwise, is that even cellulosic ethanol may be a bit of a strawman (hah!). There is no research on butanol and various other organic compounds, since they have higher energy densities than ethanol.

Fluffy | August 17, 2007, 10:55am | #

The biofuels debate lately has confused me.

I thought that the point of biofuels was to reduce dependence on fossil fuels, both for geopolitical reasons and because the biofuels are renewable while fossil fuels are finite.

There seems to be no environmental reason I can think of to move to biofuels. Burning ethanol produces CO2 too. You don't get a carbon gain by switching to biofuels. Or am I wrong about that?

Reinmoose | August 17, 2007, 11:00am | #

Predicting this kind of conflict is like predicting that at some point today, it will rain somewhere. It's far more present in more authoritarian circles where the perceived moral obligation to do something is always impeded by some ridiculously long battle about what exactly needs to be done.

thoreau | August 17, 2007, 11:01am | #

Burning ethanol produces CO2 too. You don't get a carbon gain by switching to biofuels.

The ethanol was made from CO2 taken out of the atmosphere and converted to plants, and the fuel you'll use next year will come from plants that take the current CO2 out of the atmosphere. It's a cycle, so you (ideally) add nothing and subtract nothing.

Cellulosic biofuels have the advantage that you can use more of the plant, not just the simple sugars.

Cesar | August 17, 2007, 11:07am | #

The only ethanol thats workable, cheap, and here today is sugar ethanol. Brazil already runs on it. But Brazil doesn't hold the first Presidential caucus!

"In any case, I did warn that current biofuels would chew up lots of land..."

I'm still rootin' for biofuels from algae.

"Maybe electricity produced by nuclear power plants and used by plug-in hybrid automobiles?"

And for nuclear energy and for EEstor...

"If the technology works as claimed, a five-minute charge costing $9 would give the battery enough energy to drive a small car 500 miles."

Wow, I could be misunderstanding this, but I don't think that statement could have been more wrong. You have to refine the ethanol some way, and that requires energy. Then you have to distribute the ethanol, which requires energy. You certainly don't get all the energy out of the plant when i'ts refined, so there's some loss there. Bio fuels are mixed with fosil fuels (15% for E85, 80% for B20). There's the gazillions of other factors also.
Am I correct in my having heard that engines don't get the life out of E85 that they get out of gasoline? If so, there's the extra production of cars to think about.

Horst Graben | August 17, 2007, 11:14am | #

Irrigated crop biofuel is only realistic for replacement of a low percentage of motor fuel due to limited water supply.

If the US were to convert to 100% corn ethanol as a motor fuel replacement, it would require about 100% of the total annual freshwater supply. As it stands now, the corn belt is overdrafting the Ogalalla Aquifer. Increasing irragation from this aquifer will only hasten it's depletion.

This is one of the reasons why I get so violently agitated by global warming environmentalist claptrap. Agricultural runnof is more of a concern than the potential for warming, fresh water depletion worldwide is a bigger problem and worldwide sewage treatment is a bigger problem still. Even in the US, we continue to spew billions and billions of sewage and fertilizer into our waterways. Any wonder why there are dead zones popping up in oceans?

I know it's not sexy, but these big ticket environmental impacts THAT ARE HERE AND NOW are being neglected because the environmentalists prefer to demonize corporations and the culture of consumption rather than real problems, journalists trained in socialist theory regurgitate their press releases with minimal verification and polititians afraid of leadership fall into the lemming line.

How's that for an LGF troll?

Warren | August 17, 2007, 11:18am | #

Back of the envelope calculations, figuring how many BTU's per acre, show how completely unworkable bio fuel is. And the more closely you look at the worse it gets. Right from the get-go it's a bad idea, flawed in it's conception, and at odds with well understood science. Natch, it's the favorite panacea of the global warming bunch.

thoreau | August 17, 2007, 11:18am | #

Reinmoose-

You can reserve some of the fuel from last year's crop for the purpose of refining this year's crop, and thereby run on a cycle. Farmers have done this for thousands of years, reserving some of last year's crop to feed the people who pick and process next year's crop, and to feed the animals that plow the fields and bring some of the crop to market. Replacing people with machines and bread with liquid fuel doesn't change the ability to operate a cycle.

And ethanol, as I said above, is not necessarily the final word on biofuels. Other fuels have higher energy densities, and show some promise for production. I don't know about their effects on car engines.

And, for the record, I'm cool with nuclear energy.

Michael Pack | August 17, 2007, 11:19am | #

So,let's cut down forests to grow corn and give more taxpayer money to folks like ADM.Brilliant.Never mind the pressure of food supplies.

thoreau | August 17, 2007, 11:19am | #

Warren-

I admit, I haven't done the back of the envelope calculation myself, but do those BTU calculations assume fuels made from simple sugars and starches, or fuels made from cellulose as well? It changes the density of usable energy per acre.

My point to Reinmoose was about whether it could be run on a cycle, not whether the cycle could generate enough surplus to run the US automobile fleet.

Mike Laursen | August 17, 2007, 11:21am | #

Bringing up the carbon offsets topic again, I'll concede that there are many ways to game the system, but looking specifically at carbon offsets for preserving forests I think it could work well: a parcel of forest has tangible reality; its ownership is documented; it biological history can be read by looking at its current state; and its all right out there in the open, where its value can be assessed at any level of detail desired.

To the "credit" of the more extreme environmentalists, they probably think you and I shouldn't be buying from big agro in the first place. Of course they can't get to seem through their heads that going back to completely organic, small family farms would lead to starvation for quite a number of people.

I really hate how they hijacked what it means to care about the environment. I care about the environment, I want land used responsibly, and I don't want everything paved over and built up with McMansions. But that doesn't mean I want to bring about these goals by massive government programs or undoing the industrial revolution.

Michael Pack-

Yes, the Market (peace and blessings be upon its name) determines where products will go (Amen, brother!).

So here's how the Market (peace and blessings be upon its name) would do it. Biofuel production would probably be a seasonal thing, given that it's coming from plants and all. Those biofuels would be sold on an open Market (peace and blessings be upon its name) and bought by distributors, who buy during the peak season and sell throughout the year. Those distributors would then sell some of it back to biofuel producers at Market (peace and blessings be upon its name) prices, who would use the fuel to power tractors and refineries and whatnot.

It's a cycle. Get it?

Did you know that oil companies need energy to run their operations, so they either hold some fuel back or else buy it in a different form on an open Market (peace and blessings be upon its name)?

Reinmoose | August 17, 2007, 11:34am | #

Michael Pack | August 17, 2007, 11:35am | #

I would take the ethanol crowd seriously if they also backed cleaner coal and nuclear power production and didn't need goverment handouts to produce their fuel of choice.Ethanol takes a huge tranfer of wealth from the many to enrich the few.Also,think of all the fertilizer it wiil take to produce the crops.That's more oil use and ground water pollution as a result.

Reinmoose | August 17, 2007, 11:37am | #

Don't get me wrong. I'm with Cesar on this one. I'm all about reducing the use of fossil fuels and bettering the environment, and not seeing everything paved over with Bed Bath and Beyonds and McMansions. But I think supporting bad policies because their GOAL is to reduce all this is the dumbest thing I've ever heard.

thoreau,and if you take the massive goverment support wiil it stand on it's own.Thats the true test.

thoreau | August 17, 2007, 11:40am | #

Reinmoose-

OK, let's consider another situation. Let's imagine a high tech device called a "horse." And let's say that this horse pulls something called a "plow." Now, this "horse" requires energy. So the farmer grows something called "grain", using the "horse." Some of the energy from the annual harvest of "grain" is used to feed the horse for an entire year! Another portion of that energy is reserved to feed the farmer for an entire year! The remainder is called a "surplus" and is sold.

I don't know if the size of the surplus from biofuel production will actually be large enough to power the vehicle fleet (some argue that it will actually be zero), but that's a somewhat more nuanced issue than "OMG! You need fuel to make fuel! And it isn't completely efficient!" The same objection could be applied to farming for food, and it is clearly wrong in that context. Which means that it isn't a silver bullet argument, but rather an argument that depends on the size of the surplus (if there is a surplus). So it requires data, not just "OMG! You need energy to make energy!"

Fluffy | August 17, 2007, 11:41am | #

I personally don't want a die-off, but I would be delighted if rising affluence cut the birthrate so low that the population crashed of its own accord.

Most if not all environmental issues become more manageable at lower population figures.

thoreau | August 17, 2007, 11:42am | #

Michael Pack-

Yes, but the issue of whether it's profitable on its own requires a bit more thought than "Retain fuel? Nonsense! The market decides what to do with that fuel!"

Did an environmentalist beat you up or steal your girlfriend or something?

Warren | August 17, 2007, 11:42am | #

thoreau,
As Ron states, moving to cellulose helps. And, from the couple of articles I read and interviews I've listened to, can just maybe make it pay. Maybe. You can get the BTUs/acre up easy enough with say willow, but then you get only one harvest every five years. Still under the best scenarios the bottom line comes out ahead. But not with current technology. The whole scheme depends on the creation of new enzymes and yeasts to bring down the cost of production.

thoreau | August 17, 2007, 11:44am | #

Warren-

I agree. It depends on how much energy new technologies will make available, and at what cost.

Those issues require more thought and data to resolve, not just the rhetoric some other people in this thread are throwing around.

http://www.dailytech.com/Major%2BNew%2BTheory%2BProposed%2Bto%2BExplain
%2BGlobal%2BWarming/article8450.htm


A new theory of global warming-synchronized chaos! That sounds a lot more libertarian than CO2! And the article links to another article bashing carbon dioxide as well, but it is in German or Walloon or something.

Baily is just a shill for big carbon dioxide!

I know there is a study I can't point to now that was a labratory study that showed carbon dioxide increases can initially cause a warming trend, but then the more the gas is increased, the less warming occurs. Meaning, those computer models that assume a direct link to carbon dioxide increases and warming could be completely off...

At any rate, this new theory, like the solar sunspot/cosmic ray theory, theorizes that soon, within a decade or two, we will experience a cooling trend.

So, just keep these guys fighting and keep Congress divided and maybe we can ride this thing out without carbon trading or carbon taxes!

thoreau | August 17, 2007, 11:51am | #

FWIW, I'm skeptical about the viability of current biofuels technology. I plan to buy a hybrid in a few years. Obviously, this must mean that I hate technology and corporations, otherwise I wouldn't buy a new technology from a large company. And it must be entirely because I'm an enviro-loony who hates humanity, and not because I want to save on gasoline.

Reinmoose | August 17, 2007, 11:51am | #

thoreau -
so then you admit to making an argument that ends up being completely irrelevant? Proving a condition of a theory doesn't make it profound. You really state the obvious with the "It's a cycle!" argument that you've provided... but then again, so is everything else if you really want to work on it (which is what I said in my last response to you). The "it's a cycle" approach does not mean in any way, shape, or form that it will have a negative net carbon contribution. As is even stated in this article, it depends on what the crop to be harvested for biofuel production replaces. I brought up the possibility that more cars may need to be manufactured if biofuels decrease engine life. That's just a tiny example and one possibility for offsetting any surplus energy/carbon-abatement.

Warren | August 17, 2007, 11:52am | #

thoreau,

I never object to more thought and data. The problem is, we are committing to this ill concieved plan. Legislation and regulations on everything from the corn in the ground to the gas in the pump has already been passed based on this pipe dream. And the failure of current efforts is inciting demand for increased efforts.

thoreau | August 17, 2007, 12:05pm | #

On CO2 and cycles, it works like this: You grow a plant. In growing the plant, CO2 is taken out of the atmosphere. That plant is then turned into fuel (which may be used to run the equipment for harvesting and processing next year's crop) and burned. When it's burned, CO2 is released into the atmosphere.

Burning the fuels, and letting the unprocessed leftovers decompose in the ground, cannot possibly release more CO2 than the plant took out of the air, since air is the plant's source of carbon. Now, you can talk about the CO2 emitted by the tractor and whatnot, but as long as that tractor was powered by fuel from last year's harvest (assuming there's an energy surplus) it still balances out.

So a cycle that produces an energy surplus will be carbon-neutral.

As far as energy and cycles, as long as the fuel produced can provide more than enough energy to produce next year's crop and process it into fuel (with the aid of the sun, of course, adding energy that is captured via photosynthesis), then it will work. Whether it will be cost-effective or produce enough energy to fuel the entire US automobile fleet is another issue, but the cycle will not be limited by the laws of physics, just the laws of good sense.

Oh, screw it. Environmentalists are Nazis! There, is everybody happy?

Michael Pack-

I haven't said a word in favor of biofuels subsidies. I would rather wait on adopting biofuels until the marketplace produces efficient technologies that are profitable without subsidies. What I was critiquing was some misunderstandings about using energy to produce a crop, and whether burning a plant can ever release more CO2 than it took out of the air.

If understanding energy and mass conservation makes me a socialist, well, I say "Scientists of the world unite!"

The environmentalist boosters of biofuels and the nature conservationist wings of the environmentalist movement are now duking it out.

Haahaa... I've been waiting for this to happen. Good post, Mr. Bailey.

Throeau:

fuel you'll use next year will come from plants that take the current CO2 out of the atmosphere. It's a cycle, so you (ideally) add nothing and subtract nothing.

Ideally is the watch word here. The thing that I have never seen is a comprehensive study on how much C02 is used in the entire process. Crops are sewn and planted-- x tons/pounds of co2 used to plant and sew them. x pounds/tons of Co2 is taken out of the atmosphere during the growth cycle. x pounds/tons of co2 is produced tending, caring and feeding crops. x pounds/tons of co2 are used to harvest, process and extract biofuels. x pounds/tons of co2 is used to move and transport biofuels to consumer stations.

Is it a break even, net gain, or net loss of co2?

Fluffy | August 17, 2007, 12:15pm | #

The discussion about the cycle has been very helpful.

I assumed there was no carbon benefit here because I was only thinking about the act of burning the fuel.

i didn't think about the fact that the plants are a carbon sink before you burn them.

Paul | August 17, 2007, 12:17pm | #

Now, you can talk about the CO2 emitted by the tractor and whatnot, but as long as that tractor was powered by fuel from last year's harvest (assuming there's an energy surplus) it still balances out.

I think we've had this discussion before, on another thread... but is anyone producing ethanol with ethanol? And can you? Or does your output shrink every season? Windfarms: Can wind turbines, their care, their feeding, their manufacturing, plus the power produced to electrify the homes be produced with...wind power? Wouldn't that be the ultimate test of the efficiency of an energy source?

Reinmoose | August 17, 2007, 12:18pm | #

Paul -
I think I get what thoreau is saying. If you use biofuels for every step of that process, then you are only spending your surpluss on tending to the crops/harvesting/processing/extracting/transporting.
The problem with that, that I see, is I think it requires the biofuel in question to be the cheapest source of energy, and assumes that you could spend all this money for whatever surpluss is left and sell it at a reasonable enough price that people would buy it and you'd break even.

Am I right?

Reinmoose | August 17, 2007, 12:18pm | #

I'm sorry, I'm still in viability mode

thoreau | August 17, 2007, 12:19pm | #

Paul-

As long as all of the carbon in fuels, fertilizers, and other inputs to the process is ultimately derived from plants (or animals that eat plants) then it should be carbon-neutral. If anything, it might be slightly carbon negative if there are waste products that sit in the ground rather than degrading.

Whether it will be cost-effective is a separate issue that depends on a lot of details. But the carbon neutrality just depends on whether the process (and all the inputs) can be done entirely from plants.

thoreau | August 17, 2007, 12:22pm | #

Correction:

Actually, you don't need to get all your energy from plants for the process to be carbon-neutral. You could also get it from wind, solar, nuclear or other zero-carbon sources.

The point is that if the only carbon you burn is stuff from plants, and you grow new plants to continue the process, it will be carbon neutral. Maybe even carbon negative, if there are waste products that sit in the ground and don't decompose. (Or decompose so slowly that the carbon contribution takes decades or centuries to take effect.)

thoreau | August 17, 2007, 12:23pm | #

Reinmoose-

Yes, economic viability is another issue. Carbon neutrality is necessary for it to achieve what the environmentalists want to achieve, and economic viability is necessary for it to make sense. If technological innovation can achieve both, that would be a great thing.

Of course, it might make some environmentalists happy, and we all hate environmentalists here. So that would be bad. Or something.

No, Michael Pack, you're useless as a commenter because when somebody explains that the issue of carbon neutrality depends on the inputs and outputs of the process you accuse him of being a socialist. And you're useless because when somebody discusses using the outputs of a process you rant about markets deciding.

Nothing wrong with markets deciding things, and nothing wrong with only adopting technologies that are profitable without subsidies. But if a discussion of the technical issues makes you wet your bed and see socialist phantoms everywhere, then you are useless as a commenter.

Nobody here has called for subsidies. Nobody here has even said that current biofuels (with or without subsidies) are the way to go.

Reinmoose | August 17, 2007, 12:52pm | #

On a slightly unrelated topic, though one that has been mentioned here, I really do enjoy the group mentality that is generated by these issues. Underlying motives come out all over the place and people get mad about policies not being implemented when they have no idea what those policies will actually do (see: Law of Unintended Consequences).

Pro-environment people are generally all about CAFE standards, which would inevitably lead toward more expensive or less safe cars, and result in people driving more miles, increasing our dependency on roads... something else they typically don't like. People tend to have conflicting beliefs, but they don't know it. This is something I find to be tragic in the group mentality movement.

On the flip side, many of the opposing people, who want their fossil fuels for all eternity forever and ever amen, also happen to support subsidy cuts. Meanwhile, if you cut subsidies to roads/air travel/fuel production, many of the fossil fuel related things they currently enjoy would have a really expensive sticker price and alternatives would be found.

It's really quite comical in a "the world is going down the crapper" sort of way.

Our best hope has always been and always will be new technology and the creative use of old ones...

...supercapacitors, algae bioreactors, nuclear energy, zero till--there's hope.

There's always hope. When the icebergs melt and Statute of Liberty is up to its neck in sea water, there will still be hope. People will just lean to adjust. ...and they'll come to love that old song:

When you walk through a storm
Keep your chin up high
And don't be afraid of the dark.
At he end of the storm
Is a golden sky
And the sweet silver song of a lark.

Walk on through the wind,
Walk on through the rain,
Tho' your dreams be tossed and blown.
Walk on, walk on
With hope in your heart
And you'll never walk alone.

I think you've mostly worked out your differences, but if you re-read the thread, you'll find thoreau is largely correct on the facts, and most people attempting to disagree appear to be inferring thoreau's beliefs through their anti-environmentalist filters. Try a narrow reading of his assertions without those filters.

Or, for another attempt at a explanation to Fluffy's question (2nd post), plant to biofuel to carbon dioxide to plant is a closed system, so no new carbon enters the planet's carbon cycle.

Fossil fuel to carbon dioxide to plant is an open system, with new carbon inputs to the planet's carbon cycle from sequestered sources of carbon (namely, fossil fuel reserves), which necessarily results in continuing carbon dioxide release to the atmosphere.

Other issues of course play a role, as in energy density and efficiency and economic efficiency.

Eric the .5b | August 17, 2007, 1:10pm | #

As long as all of the carbon in fuels, fertilizers, and other inputs to the process is ultimately derived from plants (or animals that eat plants) then it should be carbon-neutral. If anything, it might be slightly carbon negative if there are waste products that sit in the ground rather than degrading.

I see the fundamental logic there for expecting this to be possible, but details seem to be a problem. Even granting the sure-everything-can-come-from-biofuels premise, can any of the plants we're talking about be shown to absorb over their lifetime a net amount of CO2 at least equal to the amount of CO2 produced by the production and consumption of the fuel that can be made from them?

thoreau | August 17, 2007, 1:12pm | #

Thank you, innominate one. I was commenting on carbon neutrality, closed cycles, energy surpluses, energy densities, and things like that. I'm not interested in arguing for any of the unprofitable technologies out there currently. Rather, I'm talking about the basic scientific issues that will face anybody trying to innovate and design a new technology that is both profitable and environmentally friendly.

Somehow, that got interpreted as a call for subsidies.

thoreau | August 17, 2007, 1:18pm | #

can any of the plants we're talking about be shown to absorb over their lifetime a net amount of CO2 at least equal to the amount of CO2 produced by the production and consumption of the fuel that can be made from them?

Suppose that all of the energy used comes from burning biofuels. There's no way that burning a plant can generate more carbon than the plant took out of the atmosphere. Agriculture ran this way until the advent of fossil fuel use, with grain serving as fuel for farmers and animals.

Now, whether you can make economically viable fuels for vehicles from this process is another question. But there's no way to turn 1 carbon atom into 2, short of some fancy nuclear physics trick that does NOT happen in plants.

I have a question!
Do plants obtain carbon from the soil as well as the air?

the innominate one | August 17, 2007, 1:26pm | #

Eric-the-half-a-bee, I think a more burning (ha!) issue, as some here have pointed out, is whether the usable energy in the form of the biofuel extracted from the plant will exceed the energy used to extract it (including cultivation and all the rest).

the innominate one | August 17, 2007, 1:30pm | #

Reinmoose:

In general, no. A few plants are parasites on other plants or are otherwise heterotrophic (getting carbon compounds from organic sources), but the vast majority (all the photosynthesizers) are autotrophic, getting carbon by taking up carbon dioxide from the air (or water, for aquatic species) and "fixing" the carbon into organic compounds themselves.

Eric the .5b | August 17, 2007, 1:31pm | #

But there's no way to turn 1 carbon atom into 2, short of some fancy nuclear physics trick that does NOT happen in plants.

That's exactly the logic I understand you to be using, Thoreau, but at least one detail is a problem - plants don't pull all their carbon from the air, but get a portion from soil. That alone would make neutrality very questionable.

Is there a botanist in the house who can dish on percentages? I can only find references to carbon intake from soil, not numbers or percentages.

thoreau | August 17, 2007, 1:31pm | #

Reinmoose-

I don't know. Maybe some. But if so, that is also part of a cycle, ultimately. Otherwise plant life would not have been able to sustain itself on this planet, because it would have exhausted the carbon in the soil.

thoreau | August 17, 2007, 1:33pm | #

If they do get carbon from soil, the only way it can be replenished is from the decay of plant life. The bottom line is that if you grow plants, burn most of them, use the rest as mulch for the soil, you'll have a carbon-neutral process.

It's been working for a billion years, folks.

Michael Pack | August 17, 2007, 1:35pm | #

So this whole thread is based on carbon reduction?The cost doesn't matter.Most of the cure's are worse then the disease.Small reductions in carbon and large one's in living standards.Does anyone think Inda and China will sign on?That's 2 billion people.Any solution without involving them is pie in the sky.Will they burn oil and coal still?If we are going to transform our energy sector we must include them.Maybe we will move to more costly fuel and let others reap the benefit of fossil fuels.That's the problem with grand designs,they hit reality.

Eric the .5b | August 17, 2007, 1:36pm | #

I don't know. Maybe some. But if so, that is also part of a cycle, ultimately. Otherwise plant life would not have been able to sustain itself on this planet, because it would have exhausted the carbon in the soil.

Thoreau, the problem with this argument is that throughout the history of life on this planet, plants weren't all burned. Even now, most plants are decomposed or eaten and shat back out by animals without all or most of their constituent carbon converted to atmospheric C02.

That the biological carbon cycle has worked does not demonstrate that a grow-burn-grow cycle will be carbon neutral.

thoreau | August 17, 2007, 1:39pm | #

Most of the cure's are worse then the disease.Small reductions in carbon and large one's in living standards.

People in this thread have repeatedly talked about the need to come up with a cost-effective fuel that has a high energy density, and is renewable to boot. If it's cost effective and energy-dense, then it won't mean a change in lifestyle. If it's renewable and doesn't have to be imported from volatile Middle Eastern states then your quality of life will actually be protected against possible declines in supply or the effects of Middle Eastern politics.

Would you care to read this thread, or would you rather argue against people who aren't posting here?

Eric the .5b | August 17, 2007, 1:39pm | #

Thoreau, the problem with this argument is that throughout the history of life on this planet, plants weren't all burned. Even now, most plants are decomposed or eaten and shat back out by animals without all or most of their constituent carbon converted to atmospheric C02.

"Burning" an organic substance means that you react it with oxygen, releasing energy and CO2. In that sense, whether it's burned in the mitochondria of an animal, decomposed by a bacterium in the soil, or reacted with oxygen in the engine of a car, it all amounts to the same thing from the perspective of a carbon balance.

I don't know how much CO2 has to be replenished into the soil. But I have a hunch that farmers know. Whatever isn't converted to biodiesel, butanol (more energy-dense than ethanol) or whatever else can be used as mulch or some other type of fertilizer.

thoreau | August 17, 2007, 1:46pm | #

EDIT: I don't know how much carbon has to be returned to the soil.

Most carbon returned to the soil by animals isn't put there as CO2.

Michael Pack | August 17, 2007, 1:52pm | #

I'm sorry ,cost and how it's implemented doesn't matter.Nor does the fact if we use less oil it becomes cheaper to the rest of the world due to our huge demand being lost.If you don't sing with the choir you have no buisness here.Not all have talked about the need to reduce carbon.Some do not see a need at all.

Eric the .5b | August 17, 2007, 1:53pm | #

Correct...but if that carbon, say, gets incorporated into the structures of other living things (say, the bacteria decomposing it or the animals eating it), we're talking about the parts of the carbon cycle where that carbon never gets into the atmosphere or affects climate change.

You're talking about a mini-carbon-cycle where the plants in question aren't eaten or decomposed into soil (or otherwise have some portion of their carbon sinked), but burned. These are different things.

That the natural carbon cycle works doesn't prove the biofuels carbon cycle. I'm not saying the biofuels cycle can't be proved, but that it actually has to be proved independently.

thoreau | August 17, 2007, 1:54pm | #

Michael Pack, I know that some said I was being unfair to you, but I cannot figure out what your point is. You mostly just seem mad, and you want to treat anybody who discusses any technical aspect of biofuels as some sort of environmentalist loony, whether or not we actually area.

I'll leave you alone to argue with the strawmen in your head.

thoreau | August 17, 2007, 1:57pm | #

Eric-

If you raise the same number of plants every year, the only way to do it is to take the same amount of CO2 out of the atmosphere every year. And if you can power the tractors and refineries and whatever else without burning any fossil fuels, and if you can make fertilizer from plants or whatever else, then you aren't adding any more CO2 to the atmosphere.

Sometimes details matter. But sometimes it's enough to step back and look at the big picture. The big picture is that if you grow the same number of plants every year, then no matter what you do with them, in the end you'll have to take the same amount of CO2 out of the atmosphere every year. If you put that CO2 back, you aren't adding anything new.

Eric the .5b | August 17, 2007, 1:58pm | #

Gee, Michael, where did I first read discouraging words about ethanol in this thread...Oh, yeah.

The first comment in this thread, by Thoreau.

If you put that same or lesser amount of C02 back into the atmosphere, sure. I just get this uneasy feeling of something-for-nothing that makes me want numbers for the possible areas of wiggle-room, like carbon intake from soil.

I mean, for all I know, switching to biofuels could be a net carbon pull from the atmosphere. That or carbon-neutrality would be fine, excepting all other concerns. Even falling short of actual carbon neutrality would hardly be horrible (again, excepting all other concerns).

I'm just leery of calling biofuels carbon-neutral when that just hasn't been demonstrated.

Michael Pack | August 17, 2007, 2:10pm | #

I'm not mad.I just don't see a reliable source of bio fuel at this time.I would love to be wrong.Some time in the future I will be[hopefully].I just have this nasty habit of looking at cost and how some in goverment react.If the congress was as civil as this thread I might think otherwise.I also throw out the other side at times as a learning tool for myself.I leared much from thoreau.I never liked being in a group think situation .

Eric the .5b | August 17, 2007, 2:13pm | #

I just don't see a reliable source of bio fuel at this time.

There may not be one, and nobody here has claimed that one exists or is even known. The most hopeful person here has been Thoreau in suggesting that something other than corn-farmer-pushed ethanol might turn out to be practical.

thoreau | August 17, 2007, 2:15pm | #

Eric-

If there is significant carbon taken from the soil, that carbon has to be replaced. The only way to replace it would be with something like a mulch or fertilizer. This is what has happened with dead plants on land for a billion years, and I'm sure that the same could be done with a portion of the crop, or with some by-products left over after sugars, starches, and cellulose were converted to butanol or whatever.


Michael Pack-

I'm glad that you enjoyed this thread. But if nobody says that they want a biofuel subsidy, please don't assume that discussions of carbon neutrality are calls for such a subsidy. That might be a warranted assumption on some other forums, but not here on Hit and Run.

thoreau | August 17, 2007, 2:16pm | #

The most hopeful person here has been Thoreau in suggesting that something other than corn-farmer-pushed ethanol might turn out to be practical.

Ken Shultz did say something about algae, and he's expressed some interest in biofuels on other forums at other times. But nobody in his right mind could mistake Ken Shultz for a fan of subsidies.

Paul | August 17, 2007, 2:16pm | #

Personally, I don't know how any of you guys interpreted thoreau's comments as a call for subsidies.

The economic question however, should be taken into account-- to some degree. It's difficult because of regulatory layers, but in a more pure context, it does count. If you look at all the energy inputs for a system that sends energy out, costs can be used as a factor to figure out if you're efficient.

Ie, if I produce wind power, but I had to spend $90,000,000 dollars in fossil fuels to build, manufacture, distribute, care and feed my wind farms, that's what's called an "economic signal" that wind power isn't free. It's also an environmental signal, if you will, that tells us that wind power may not be carbon neutral, or even carbon negative. This goes for ethanol as well. When a manufacturer can't make his model work because he's spending too much in other energy inputs, and calls for subsidies, therin lies the problem.

thoreau | August 17, 2007, 2:18pm | #

If there is significant carbon taken from the soil, that carbon has to be replaced.

EDIT: That carbon has to be replaced if you want to grow crops every year.

Isaac Bartram | August 17, 2007, 2:27pm | #

I'm not mad.

There's a distinct tone of annoyance in your posts. I have found some of your posts more abrasive than necessary. And might I add, more abrasive than usual for you.

I just don't see a reliable source of bio fuel at this time.I would love to be wrong.Some time in the future I will be[hopefully].

thoreau has just engaged in a theoretical discussion of technical aspects. Technical musings are not advocacy in and of themselves.

Everything requires an analysis. After all, how are we to know if there's a "a reliable source of bio fuel" out there if we don't look at the merits once and awhile?

Reinmoose | August 17, 2007, 2:27pm | #

As I'm reading Eric the .5b's comments, I realize that he's expressing more-or-less the concerns that I wanted to express at the beginning, but was not nearly so eloquent in my attempt.

Adam | August 17, 2007, 2:28pm | #

This is one of the reasons why I get so violently agitated by global warming environmentalist claptrap. Agricultural runnof is more of a concern than the potential for warming, fresh water depletion worldwide is a bigger problem and worldwide sewage treatment is a bigger problem still. Even in the US, we continue to spew billions and billions of sewage and fertilizer into our waterways. Any wonder why there are dead zones popping up in oceans?

I suspect the real reason you get "violently agitated" is that you are filled with the same strange resentment towards strawman environmentalism that animates much knee-jerk anti-environmentalism. More simply, I suspect you're just an asshole.

I say this because none of the actual substance of what you're saying is even remotely controversial in environmental circles. You could have cut and pasted it from Grist. But you go, girl! Get violently agitated!

I know it's not sexy, but these big ticket environmental impacts THAT ARE HERE AND NOW are being neglected because the environmentalists prefer to demonize corporations and the culture of consumption rather than real problems, journalists trained in socialist theory regurgitate their press releases with minimal verification and polititians afraid of leadership fall into the lemming line.

Again, photosynthetic crop plants get almost all of their CO2 from the air, as I understand. Whatever they get from soil has to be replenished with fertilizers if you want to grow more crops next year. If the fertilizers are also derived from plants then it is carbon neutral.

It's how these cycles operated for a billion years.

And the majority of fertilizer used in this country is made from...? :)

This is what has happened with dead plants on land for a billion years

Thoreau, seriously - you can't make huge assumptions about a cycle of agriculture, industrial processes, and pollution based on the billion years without agriculture and industrial processes.

The claim of carbon neutrality can only be shown by comparing atmospheric CO2 taken in by a given biomass of plants used to the CO2 produced by burning the fuel produced from that biomass. Anything else is questionable.

I don't know what more I can add, so I won't belabor the point.

the innominate one | August 17, 2007, 2:38pm | #

I agree with thoreau in that I don't understand the point that Michael Pack is trying to make, but it's not worth worrying about. He doesn't seem to read other people's posts (especially thoreau's) without his red filters on.

I don't understand Eric's point either, and I'm trying to. Where are you getting the idea that plants get carbon from the soil?

Most fertilizers are N-P-K fertilizers: nitrogen, phosphorus, potassium. Not carbon.

Eric the .5b | August 17, 2007, 2:38pm | #

I have no idea how you talk about carbon neutality without the cost

Because he's talking about the question of carbon neutrality. Not whether biofuels are practical or cost-efficient or otherwise desirable, or whether biofuel research will result in carnivorous Triffids stalking the land.

That said, I'm out.

The other day my wife took the car to the mechanic. First she asked which parts would be needed to make it work, i.e. she addressed the technical issue. Then she asked the price tag. See how that works?

I'm not sure who you are to say what should be on hit and run

I didn't say what should be on Hit and Run. I said that most people here are NOT fans of subsidies, so don't read a Hit and Run thread and assume that any discussion of biofuels is an implicit call for subsidies.

As to the article's point about carbon neutrality, my brief perusal indicates that they worry about the effects of clearing land to make room for agriculture. The annual cycle of growing and then burning would still be carbon neutral, but the initial clearing would not be. I was talking about the annual cycle.

The initial clearing could be minimized if people develop ways to get the most energy per acre.

Eric-

For most of human history, agricultural fertilizers were made from plant and animal products, not fossil fuels. Note that I'm now making a comparison with thousands of years of agriculture, not with a billion years before agriculture.

And, as I understand it, the vast majority of carbon used by photosynthetic crop plants comes from the air, not the soil. Whatever small amount they get from the soil could undoubtedly be replenished with waste products from the biofuels process.

"Soil DIC contributed ~0.8% to whole- plant C gain..."

OK, I see the red herring. DIC = dissolved inorganic carbon = carbon dioxide or bicarbonate ion or carbonate ion.

It doesn't matter whether plants get carbon dioxide from soil or atmosphere, since carbon dioxide can move between these two sources. Plants get carbon by removing carbon dioxide as a whole. They aren't taking up organic carbon from the soil, which is what I thought you were implying, Eric.

I apologize for being away from the discussion so far today. I was finishing another article. This may be too late, but I have seen a number of reports that estimate the corn based ethanol nets only 15 to 20 percent of energy after fuel production costs are taken into account. Basically, a huge energy cost is distilling the alcohol from the water. Anyway, the only thing I could lay hands on with quick google search is this Oregon State U release describing such a study here.
There are bunch more such studies. Note that the OSU study says that net energy balance for cellulosic ethanol is 84%. However, another new study finds that the capital costs of cellulosic ethanol means that there is no price advantage for it over corn-based.

No simple solutions anywhere; vested interests everywhere.

This is another major carbon pollution source that needs to be eliminated to save the world.

"There is no research on butanol and various other organic compounds, since they have higher energy densities than ethanol."

Dr. T, of late there has been a fair bit of research into dimethylfuran as a gasoline substitute. The cal/mole looks to be a bit better than gasoline(!). A new industrial production technique looks feasable. Toxicity is being studied.

And Micheal, this process is carbon neutral because the aforementioned moles use the excess carbon to line their nests, thus sequestering it in the ground.

Will these moles be subsidized?

Well, I heard that Avogadro supported Big Mole.

Cool! Do you happen to have his number?
