Move to a Mainframe, Earn Carbon Credits

BBCWatcher writes "As Slashdot reported previously, Congress is pushing the U.S. Environmental Protection Agency to develop energy efficiency measures for data centers, especially servers. But IBM is impatient: Computerworld notes IBM has signed up Neuwing Energy Ventures, a company trading in energy efficiency certificates, in a first for "green" computing. Now if your company consolidates, say, X86 servers onto an IBM mainframe on top of slashing about 85% off your electric bill each megawatt-hour saved earns one certificate. Then you can sell the certificates in emerging carbon trading markets. IBM's own consolidation project (collapsing 3,900 distributed servers onto 30 mainframes) will net certificates worth between $300K and $1M, depending on carbon's market price. Will ubiquitous carbon trading discourage energy-inefficient, distributed-style infrastructure in favor of highly virtualized and I/O-savvy environments, particularly mainframes?"

The whole concept of "carbon neutral" and off-setting your carbon emissions for whatever reason seams kind of lame to me. Instead of continuing to do things that cause global warming while doing other things to supposedly reduce your "carbon footprint", why not just try to eliminate or reduce the problems in the first place? It's not just individuals, it's the whole mindset of society. Instead of going for carbon-neutral server farms, why not develop cleaner alternative electricity options to power those server farms? Solar power could do a lot, but we'd rather earn carbon certificates. It just doesn't make sense.

Re:Carbon credits = lame

The point of carbon credits is to do just that. The credits are supposed to reward people putting in these more energy-saving machines.

Re:Carbon credits = lame

[Ost99 (101831)]

First of all, the idea that developing countries will get larger quotas than they currently use is wrong.

To get the credit market to work, you need to make sure there are higher demand than supply, that should not be hard.

Here (in Norway) the state will not issue any "free" credits to the industry.
The state will sell credits for up to 85% of our current emission levels, above that the industry will have to buy credits abroad or reduce their emissions.

Reduction abroad will in many cases be less expensive than domestic reductions (both because the implementation cost will be lower in a developing country, but also because the cheaper "early" improvements already has been done at home). As long as credits bought from abroad reduces emissions where they were bought, the system works.

There are also individuals and organizations positioning themselves to buy up credits without any intentions of using them.

The credit system will be make sure that existing emission-reduction technology will be implemented as soon as the credit price rise above a certain level. What it will not ensure is funding for long term research into new solutions.

Research into new energy sources and emission-reduction technology still needs heavy governmental support. A good start would be 1% of GDP for all industrialized countries.

The nonsense about the carbon credit system being a wealth redistribution system is just stupid.
Giving / implementing emission-reduction technology to the industry in the developing is in no shape or form redistribution of wealth, it's saving our bacon.

And remember, a large part of the industry in the developing countries is owned by multinationals, if the carbon credit system did not include those countries, all that would happen is that even more of the worlds production would "globalize".

Re:Carbon credits = lame

[Antity-H (535635)]

Actually it does according to market theory.

Currently the market does not integrate the cost of emitting carbon in the atmosphere. As a result the carbon emitting technologies seem to be less expensive for the same result and the market logically develops these. Introducing a feedback in the market that the carbon emissions actually has a cost sends a message saying that carbon emitting tech is not the most efficient choice. The market will find an alternative solution instead of a solution being forced on it which might not be the most efficient in the end.

You mention that you want to eliminate the problem in the first place then you mention solar power, but how do you know that solar power is the best, or that nuclear power is? Maybe it's wind based, or ethanol based, or hydrogen based power or even cattle based power that's the most efficient. Or maybe a company will start doing research because there is a market for it and someone will come up with a transimentional p0rn energy extractor or even an Anonymous Coward based power source, who knows ?

The thing is the market will integrate the feedback signal and propagate it. This avoids forcing decisions on the market about the solution, the certificates are only reminding it of the problem. Going for carbon-netural server-farm is simply passing along the signal back to energy producers.

It looks like it's working for other problems.IIRC sulfur dioxid emission certificates led companies who claimed that installing an emission cleaner for it cost too muuch to actually install them even though buying the certificates seemed to cost less. the real price (vs company reported) of installing the cleaner was less than trading certificates in the long term thus they ended up investing.

Let's hope it will work for carbon too.

Re:Carbon credits = lame

[IamTheRealMike (537420)]

the IS NO COST to emitting carbon that anyone can quantify as yet

Sure there is. Just make an organization liable for the costs of climate-change related damage relative to the amount of CO2 it directly emits. You already have to buy carbon credits if you emit CO2 so we have a registry of who emits and how much. This way, the cost is amortized over the whole economy, increasing our ability to manage it (via general price increases).

For instance, let's say that mosquitos start moving up into Europe and spreading various nasty diseases. The health insurance claims for these events can be claimed back from the economy as a whole by suing the CO2 emitters in a class action suit. The details of whether a particular problem was caused or the risk increased by climate change can be thrashed out by the courts. I sense some scepticism in your remarks over whether climate change is real - that's OK, you can believe what you want, but I suspect when put in a court any such defence would have a hard time in the face of a nearly unlimited supply of expert witnesses. The CO2 emitters would be forced to try and calculate the risk to the environment from what they do based on what they believe and the advice their experts give them, and would then pass that on to their customers, thus the "true cost" of climate change would ripple through the economy.

This has benefit over the rather artificial carbon credits market, in that the "cost" of emitting a ton of CO2 is - as you rightly point out - basically pulled out of somebodies arse right now. What's more, they were deliberately set low enough to not have any impact on existing businesses, so instead of bringing about real change they just brought extra democracy. The idea of using markets to take action is the right one, but the "risk premium" needs to be priced into everyday goods.

I just made this scheme up off the top of my head. There are several key objections I can anticipate. The first is that climate change seems likely to kill a lot of people via disease/drought/etc, if indeed it's not doing so already, and how can you price a human life? Well, it is possible, but only in various untasteful ways. I don't think this one is solvable, nor should it detract from the scheme - the market is a tool and we need it to serve us now, to reach our end goals.

The second is that it would be inflationary if enacted globally, at once, because it would lead to a round of general price increases which would then in turn cause more borrowing by those without the spare cashflow to absorb it (ie, most people these days), thus inflating the money supply. This is especially true of essentials like oil (let's ignore peak oil for now). Inflation in the presence of a general price increase is not inevitable assuming you define inflation as an increase in the size of the money supply - that's an artifact of the fractional reserve. Replacing the fractional reserve with something less prone to inflation is certainly a good idea. But, if you suppress inflation (eg, by going to a Robertson/Huber type money supply), a general price increase makes us all poorer. That's more or less inevitable though - we would simply be paying what other people less able to pay (because they just lost their food supply/health/whatever) would be paying anyway, but everyone pays a small amount now instead of watching and saying "I hope that never happens to me". It's not a different concept to insurance in fact, but it's not optional, because climate change affects everyone.

The third is that it requires everybody to act more or less in concert. Unfortunately the "race to the bottom" is a general problem with regulating business and should not discourage us from working together to do so.

There are probably more problems with this scheme, but it does have the advantage that carbon emission is priced "naturally" and integrated into the sticker price of things like a unit of electricity - if you can get yourself out of the CO2 emitters game by replacing your electricity usage with solar or wind (or even nuclear!) then you are no longer liable for potentially huge disaster-relief costs, thus you can lower your prices, gaining an advantage over your competitors.

[Alchemist253 (992849)]

Part of the problem is that we see a perpetuation of the myth that everyone's opinion is equally valid on this issue (or any issue, for that matter).

There is of course the old phrase, "you are entitled to your own opinion, not to your own facts." But let's suppose that everyone agrees on the basic facts. The facts in question are not things like global average surface temperature; the global warming opponents are correct that we do not have actual temperature data for most of the planet's history. Instead, the facts are more obscure: oxygen isotope ratios, nitrogen exchange rates, geological strata, etc.

Valid interpretation of these data (and their significance vis a vis human involvement) is HARD! I am an organic chemist by training, which probably makes me better suited to analyze the facts than most, but even I readily admit that I have difficulty deciphering the maze of evidence out there. Fortunately, there are others (climatologists) who have spent decades or longer learning all there is to know about climate science, and scrutinizing the data. The OVERWHELMING CONSENSUS among PhD-level climatologists (and I know a few personally) is the global warming is REAL, and is HUMAN CAUSED.

Now, the problem arises when politicians, businessmen, and even scientists stepping outside their discipline start second-guessing the climatologists' work. I submit that unless you have equivalent training, education, and experience as those with whom you disagree on a fundamentally scientific issue, your opinion COUNTS LESS. I completely ignore the ramblings of the people talking about sunspots, et cetera, because I trust that the majority of climate scientists knows what it is doing. My only alternative is to go for a PhD in that field, and start slowly bringing myself to the majority's level.

It strikes me as interesting that most people (not necessarily most on Slashdot, though) tend to willingly accept the pronouncements of auto mechanics, physicians, and electricians, for example, all of whom are similarly professionals but working in fields much more comprehensible and accessible than climate science.

At the bottom it says "But overall, US adults have the biggest annual travel carbon footprint in the world at 7.8 tonnes, more than double France's 3.7 tonnes, which comes in at number two. Third on the list, at 3.1 tonnes, is Britain." -- the USA is a big jump ahead of France there!

For instance, "If one in 10 Americans used public transportation regularly, U.S. reliance on foreign oil could be cut by more than 40 percent--the amount we import from Saudi Arabia each year." (source). This notes that public transport use in America has now got back to the level it was at 50 years ago -- I don't know how much settlement density has changed in that time, maybe people have left cities a lot (?), but if it used to be possible, why isn't it possible any more?

I'd be surprised if 1 in ten Americans (30 million people) weren't using public transportation regularly. In NYC, it's a much larger hassle to have a car (fees, tolls, paying for parking, etc) than it is to take the subway. The same is true of nearly every city I've been to in the eastern half of the US (Seattle being the only city I've been to on the west coast and that was either walking or driving around with my girlfriend so I didn't check out their public transportation).

Outside of the cities (ie the vast majority of the US), public transportation just isn't possible. I live in a town of 7000 people with about 100 miles of road. We have a grocery store in town but I need to go 15 miles (one way) to get a decent selection of food at a reasonable price (a large national chain and another regional chain), to buy clothes, etc. I need to go 25 miles in another direction to get to specialty stores. It's not economically feasible to build a million little stores to service a couple dozen people each. It's also not feasible to expect people to walk up to 5 miles just to get to a public transportation station that will zip them off to those locations once an hour (damn, you missed it by 5 minutes and now have to wait almost an hour). Oh, double the buses, trains or whatever? Ok, you just doubled the carbon output (and costs) and halved the ridership of each transport. You certaintly can't solve the problem of distance to the station by running more transports around to pick people up (they'll be empty most of the time and will end up creating more carbon emissions than cars. For reference, it costs about $400k a year (not counting acquisition of new buses) to bus our kids to/from school on predetermined routes twice a day). The vast majority of the country (excluding dense, urban areas) is even far less dense than my town (190 people/mi^2 or 73.5/km2). I've been places where the distance to the nearest neighbor is measured in miles.

Finally, only half of the oil used by the United States goes to create gasoline. A quarter of it alone goes to home heating and most of the rest is used for farming and industrial purposes. If gasoline makes up 50% of our oil useage and 10% of Americans using public transportation means cutting oil consumption by 40%, that means that we'll see a 80% reduction in gasoline useage from a 10% increase in transportation. Why, at that rate, if we get 50% of people to use mass transportation, we'll not only stop using gasoline entirely, why we'll be creating 4 times more gasoline out of thin air than we consumed beforehand. Without looking at it, I'd say their numbers are flawed (or highly skewed to consider the 10% only those who use the most gasoline).

Why does the US use so much gas to get around? Again, it's a big place with a low density so mass transportation just can't work. People like having the freedom of getting in their car and going somewhere on their schedule rather than when some department of transportation decides they can move from point A to point B (and you're screwed if you miss the last ride of the night because you had to work late... it's not a matter of walking a mile pissing and moaning about your luck, you might be walking 50 miles or paying out the ass for a

"poverty creates plenty of carbon output. burning dirty sources of heating and collected wood in inefficient fireplaces etc. and in other countries, its slash and burn"

That "inefficient" wood is not contributing at all to global warming. When you cut down and burn a tree, you're releasing the stored carbon of that tree. As other trees grow, that carbon is re-absorbed, and released when that tree is cut down in turn. It's all part of the current carbon cycle.

The problem with stuff like coal and oil is that they represent carbon which has been out of the cycle for millions of years. When you burn them, you're adding more carbon to the cycle than the world's forests can cope with. Deforestation (which is primarily caused by wealthier civilizations, rather than poor ones with no means to cut down forests on a large scale) only accentuates this.

Slash-and-burn agriculture is ecologically destructive, but it doesn't contribute to the carbon problem. Like burning trees, it's all part of the current carbon cycle. As the land lies fallow and the forest regenerates (prior to the next round of slash-and-burn) the carbon released is reabsorbed. As I said, it causes other ecological problems, like soil erosion and habitat destruction, but it's no more a contributing factor to global warming than any other method of turning woodland into farmland.

In the end we'll end up with just 5 huge mainframes in the world as foretold by the IBM executive in the 50's? (can't remember where he was quoted).

A carbon credit is a permission to pollute

[Colin Smith (2679)]

At the moment there is no permission required to pollute, you could pump as much CO2 into the air as you like. Well, instead of that the government says:

1: You need permission to pollute.
2: You get those permissions from the carbon credit markets.
3: You have to buy them at whatever they cost in that market every year.
4: You can sell permissions if you have more than you need.

Then the government auctions enough credits to represent a slight reduction in the overall production in CO2. Each credit might represent one tonne of CO2. Then each year the government reduces the numbers of credits available in the market. The cost of a credit then increases simply due to the reduction in supply or the increase in demand.

As the cost of emitting the CO2 increases, companies will switch to alternative solutions, choosing whichever they like best.

Of course, this only works if politicians aren't completely corrupt or utter morons, as seems largely to be the case. In that case they might give companies credits and allow them to sell them on the markets, it's basically free money to those companies which receive the credits.

Here's a thought, focus on the worst pollution areas of the world like China and reduce air travel by half - why do people fly so much if it's such a hassle to fly, especially to/from/within the USA?

Why? A 747 gets 100 miles per gallon per passenger.

http://www.howstuffworks.com/question192.htm [howstuffworks.com]

This sounds like a tremendously poor miles-per-gallon rating! But consider that a 747 can carry as many as 568 people. Let's call it 500 people to take into account the fact that not all seats on most flights are occupied. A 747 is transporting 500 people 1 mile using 5 gallons of fuel. That means the plane is burning 0.01 gallons per person per mile. In other words, the plane is getting 100 miles per gallon per person! The typical car gets about 25 miles per gallon, so the 747 is much better than a car carrying one person, and compares favorably even if there are four people in the car. Not bad when you consider that the 747 is flying at 550 miles per hour (900 km/h)!

Better than one person in Prius.

http://www.toyota.com/prius/ [toyota.com]

The Prius boasts an EPA-estimated combined city/highway rating of 46 miles per gallon

Two or more in people in Prius will beat a 747. Or maybe not, loading up a car will cause the total miles per gallon to drop as the weight increases. Maybe you need three people in a Prius to be safe. But most cars have one person and lower mpg, so it's not like 747s are worse on average than cars.

Power Consumption Predictions

[BBCWatcher (900486)]

As a general rule, if you're building a business computer and want to save as much as electricity as possible, the most highly virtualized (and virtualizable) platform wins. So attributes like massive caches and screaming I/O help enormously. (I think there was a Stanford study recently that figured this out.) Thus it's no surprise a modern mainframe is more energy efficient than anything else.

But in the Computerworld article referenced in the original story, IBM says the carbon program will also be available for its System p servers at some point in the future. My prediction is that you'll typically get fewer certificates if you move to System p versus System z, but it's likely businesses will do some of both depending on what sort of applications they're rehosting. There are some types of applications that will do better on System p, and there is some software that runs on AIX that doesn't run on z/OS or Linux.

Regarding SPARC it's impossible to say since Sun hasn't entered into any carbon credit auditing system yet. The IBM-Neuwing program is a first. However, my prediction is that you'll get even fewer certificates if you consolidate to SPARC. I say that simply because I assume IBM is acting in its own self-interest, and I'm sure they think the energy efficiency fight is one they can win against other vendors. In this case self-interest and environmentalism coincide. For any of these platforms, though, businesses will figure out whether the certificates favor certain platforms over others, and they'll do that application by application (or application function by application function). And many other factors will go into the decision as well, although most of those factors pull in the same direction as energy efficiency, such as software charges. One could even imagine that before long server vendors lagging in the energy efficiency department will start bundling carbon certificates with their servers in order to compete. Thus IBM adopting this program is a smart way to respond to an untapped market need and to raise the effective price of competing servers compared to IBM's. Very smart move.

By the way, the world has totally flipped on its head, and it would be extremely misleading to say an IBM mainframe is "proprietary" and X86 (for example) isn't. What does proprietary mean? You can run pure 100% GPL Linux on an IBM mainframe -- Debian, Slackware, CentOS, etc. -- and you don't even need a closed source driver as you usually need for X86 servers. IBM publishes extreme instruction-level detail in a free book called Principles of Operation [ibm.com], and it's so detailed and thorough that the open source community created an implementation of the instruction set called Hercules that actually works compared to still imperfect efforts like Bochs and QEMU. (Although IBM may assert patent claims on its processor architecture.) One company is porting OpenSolaris to System z, and they didn't even have to ring up IBM. In comparison, Intel and AMD also may assert patent claims, and AMD is suing Intel for alleged monopolistic behavior. Neither Intel nor AMD publish PoO-type documents (to that level of detail). Then there's Microsoft Windows, and it's hard to think of any more proprietary OS than that.

Also, IBM changed the way it charges for z/OS software about 7 years ago. Now almost everything is charged by the amount you actually use, something IBM calls Variable Workload License Charge (VWLC). If you run a little bit of DB2 in one LPAR (partition) but a lot of IMS in another, then you pay a little for DB2 and more for IMS. You also control exactly what you consume using something called softcaps, and you can set those either per-LPAR or for a group of LPARs. One interesting little twist to mainframe subcapacity licensing is that, if you need a little bit of WebSphere (and a lot of other IBM products), the lowest entry price (smallest license you can order) is for z/OS. You can order as little as 1 "Value Uni

[Nerdfest (867930)]

It all sounds like a very workable idea until you have to move from pretty much any other operating system to z/OS. The fact that JCL is still used anywhere astounds me. Once you're actually in a linux partition things are OK, but the rest of the environment is in need of serious usability improvements. There also seems to be a tendency to develop huge amounts of restrictive process around mainframes (a la 'The Difference Engine' almost) ...

To quote their first "argument": "Scientist are doubtful that CO2 harms the climate."

[jgiltner (861452)]

Not sure what type of data center you are in, but we still need 3-phase power for some of our non-zSeries boxes. Most blade servers require it. Our non-zSeries boxes generate more heat and draw more power than our 2 zSeries servers combined and we only have about 70 small Intel/AMD based system. True you can't run x86 binaries on a zSeries, but you can't run zSeries binaries on a x86 and didn't seem to be a problem when everybody started to migrate away from the mainframe. Why should it be a problem to mi
