The Crux of the Climate Debate

Cross-posted from Climate Skeptic

I wanted to link to Richard Lindzen's Congressional testimony.  For slides, they are pretty easy to follow as they are mostly text.  I want to particularly point out slide 4, which I think on one page outlines the single most important point to understand about anthropogenic global warming theory.  When given just one minute to discuss climate, this slide embodies the message I give.

Here are two statements that are completely agreed on by the IPCC. It is crucial to be aware of their implications.

1. A doubling of CO2, by itself, contributes only about 1C to greenhouse warming. All models project more warming, because, within models, there are positive feedbacks from water vapor and clouds, and these feedbacks are considered by the IPCC to be uncertain.

2. If one assumes all warming over the past century is due to anthropogenic greenhouse forcing, then the derived sensitivity of the climate to a doubling of CO2is less than 1C. The higher sensitivity of existing models is made consistent with observed warming by invoking unknown additional negative forcings from aerosols and solar variability as arbitrary adjustments.

Given the above, the notion that alarming warming is "˜settled science' should be offensive to any sentient individual, though to be sure, the above is hardly emphasized by the IPCC. 4

My most recent climate video, which discusses this issue and more, is here.  I also have an older, shorter video focusing on just the issues in Lindzen's fourth slide here.

More Green Silliness

I couldn't care less what happens to my body after I die and I am done using it.  So the following, which I suppose is intended to freak me out, simply leaves me amazed yet again at green thinking

Undertakers in Belgium plan to eschew traditional burials and cremations and start dissolving corpses instead.

The move is intended to tackle a lack of burial space and environmental concerns as 573lbs of carbon dioxide are released by each cremated corpse.

Under the process, known as resomation, bodies are treated in a steel chamber with potassium hydroxide at high pressure and a temperature of 180c (350f).

The raised pressure and temperature means the body reaches a similar end point as in standard cremation "” just bones left to be crushed up "” in two to three hours.

My first thought on reading this was "Soylent Green is People!"

My second is to wonder how a torched body creates 573 pounds of CO2.  12 pounds of carbon combusts to 44 pounds (approx) of Co2.  This means that to combust to 573 pounds of Co2, the human body must have 156 pounds of carbon.  WTF?   But carbon in 18% of human body weight, which means that to produce 573 pounds of CO2, the human body would have to weigh 867 pounds.   One might be able to get this number by including the cremation fuel in the equation (though this is a generous interpretation since this is not how the article is written), but since it is usually gas used for cremation it would take a hell of a lot of gas given its low carbon content.

My third thought is what does any of this have to do with CO2 reduction

  • The process occurs at 350F.  You mean no fossil fuels are used to get the chamber up to 350F.  What, are they using solar mirrors?
  • The process occurs at high pressure.  This takes energy
  • The end product is a carb0n rich soup that they pour down the drain or pour on their garden.  I have a clue for you, all oxidation is not combustion.  That carbon dumped in your garden or in your compost heap will still become CO2 even without seeing aflame.

"Green Jobs" Are Starting To Sound a Lot Like Those Jobs At The Museum of Science and Trucking on the Sopranos

Via Christopher Horner:

Spain's Dr. Gabriel Calzada "” the author of a damning study concluding that Spain's "green jobs" energy program has been a catastrophic economic failure "” was mailed a dismantled bomb on Tuesday by solar energy company Thermotechnic.

Says Calzada:

Before opening it, I called [Thermotechnic] to know what was inside "¦ they answered, it was their answer to my energy pieces.

Dr. Calzada contacted a terrorism expert to handle the package. The expert first performed a scan of the package, then opened it in front of a journalist, Dr. Calzada, and a private security expert.

The terrorism consultant said he had seen this before:

This time you receive unconnected pieces. Next time it can explode in your hands.

Dr. Calzada added:

[The terrorism expert] told me that this was a warning.

The bomb threat is just the latest intimidation Dr. Calzada has faced since releasing his report and following up with articles in Expansion (a Spanish paper similar to the Financial Times). A minister from Spain's Socialist government called the rector of King Juan Carlos University "” Dr. Calzada's employer "” seeking Calzada's ouster. Calzada was not fired, but he was stripped of half of his classes at the university. The school then dropped its accreditation of a summer university program with which Calzada's think tank "” Instituto Juan de Mariana "” was associated.

Additionally, the head of Spain's renewable energy association and the head of its communist trade union wrote opinion pieces in top Spanish newspapers accusing Calzada of being "unpatriotic" "” they did not charge him with being incorrect, but of undermining Spain by daring to write the report.

Green Rent Seeking Update

More here on the failure of European green energy subsidies.

At a speech a while ago, I told this to an investing group a while back:  Do the math.  You can't build a growth company on public subsidies.  It may be possible to grow at first when the subsidized activity (e.g. solar) is a tiny percentage of the market.  But once it starts to grow, the projected subsidies are astronomical.  The German solar subsidy is something like 50 cents per KwH -- to give one a sense of scale, the typical electricity price from fossil fuels there or here is something like 8-10 cents per KwH.  Subsidizing just 20% of US electricity production at this kind of rate would cost $50 billion a year.  Subsidizing all production would cost a quarter of a trillion dollars a year.

Take a company dependent on subsidies, figure out what their implied size is in 10 years based on current stock multiples, and then calculate what the public subsidy at current rates would have to be to support that size and a reasonable market share (because competitors are following the same model).  Investors who do this will quickly figure out that the subsidies needed to support their favored company are unsustainable.  Phoenix-based FirstSolar, a sometimes-darling of Wall Street, has had  a rocky year.  Its stock price has had several steep falls, each one just after rumors that Germany would cut its solar subsidy rate (actually its feed-in tariff, but the same idea).

My advice to the group was that if you were investing in green energy, either your company had a three year plan to reduce costs to be able to compete profitably in a subsidy-free environment, or else you are investing in pets.com.

Update: If you have Nancy Pelosi's husband on your board, you can probably extend your window to five years.

Duh

Of course this was going to happen.

An audit of solar-power generation from November 2009 to January 2010 found that some panel operators were paid for doing the "impossible" -- producing electricity from sunlight during the night, El Mundo reported today, citing a letter from Secretary of State for Energy Pedro Marin....

Preliminary evidence shows some solar stations may have run diesel-burning generators and sold the output as solar power, which earns several times more than electricity from fossil fuels, El Mundo said, citing unidentified people from the energy industry. The power grid received 4,500 megawatt-hours of power from midnight to 7 a.m. in the months audited, El Mundo said.

Electric current is electric current.  However, in a country like Germany, the price that utilities are required to pay for electric current varies based on its source.  While electricity from, say, a diesel generator gets 4-5 Euro cents per KwH, ground-based solar gets about 48 Euro cents per KwH.  This is a 10x greater price paid solely for absolutely identical power manufactured in a different way.  So of course there is going to be fraud as to the current's source.

I Need Some Help on Alternative Energy Subsidies

Next week I am on a panel talking about alternative energy.  These guys have already told me they don't want to re-fight the global warming science battle at this venue, and my guess is that there will be a lot of pragmatist corporate types who won't really care about individual liberty or role-of-government issues  -- they will only care if there is money to be made, even if it is by rent-seeking.  My best bet, I think, will be to discuss why alternative energy is a bad investment.  My sense is that it is a bubble investment, like goofy Internet stocks in the 1990's or housing in the 2000's.  Already, I think we see the crash in the corn ethanol business.

My two assumptions are

  • I can't think of any industries that were initially heavily subsidized that eventually found their way to competing successfully and growing without subsidies.
  • With the exception of agriculture, the public's tolerance for growing subsidies to a single industry eventually wanes.

I would love for commenters or emailers to send me contra-examples if they have them to either of these assumptions.  In particular, can you think of an industry that could not have grown initially without subsidies eventually prospering without subsidies.

To the second point, I looked at the numbers two ways.

  1. In Germany, which is often held up as the model, feed-in tariff subsidies are between $0.06 (wind) and $0.50 (solar) a Kwh.  If the US reached a goal of 20% of its production in wind and solar (total production today is about 4000 billion KWh) then the subsidy would be between $50 billion and $400 billion a year.  It is hard to imagine these remaining popular for any period of time.  (lots of German numbers here and in the linked PDF)
  2. Venture capitalists and investors are expecting the growth stocks they invest in to grow at, say, 30% a year.   Let's assume alternative energy companies grow at 30% a year and the number of companies, attracted to the growth and subsidies, doubles every two years.  In this scenario, assuming unrealistically that the supply curve for alternative energy is flat rather than upward sloping, the amount of subsidies to support this growth would have to nearly double every year.  They would increase 21-fold in five years and 440-fold in 10 years.   In fact, given the shape of real supply curves, new more expensive capacity at the margin is replacing cheaper and cheaper alternatives, resulting in the need to grow subsidies even faster to keep up.   Never has happened, never will.  Once the industry outgrows the government's willingness to grow subsidies, the whole thing crashes.

(PS - the subsidy could also be in the form of taxes that increase the cost of alternatives, or production and/or import restrictions on the alternatives).

Any help along these lines in the comments is appreciated.

Update: This seems relevant:

First Solar shares skidded 8% Friday to close at $116 after the company issued a murky business outlook beyond June. Until then, however, "orders look very strong," First Solar CEO Robert Gillette said in a post-earnings conference call.

This commentary, along with price pressure and expected subsidy cuts solar panel makers get from the German government is making investors a bit more wary of First Solar, whose shares have been on a bumpy ride the past 18 months....

First Solar, helped by government tax credits extended to businesses for using solar power, has rewarded its investors since going public in November 2006 at $20 a share. The stock peaked at $317 in May 2008. But the shares have been skittish ever since.

Germany, the world's biggest solar market, is weighing a 15% cut on so-called solar feed-in-tariffs. This could make solar installations less attractive.

First Solar projects 60% of its 2010 sales from German-related contracts, according to Wedbush Securities analyst Christine Hersey.

Remember from above, the German feed-in tariff for solar is around $0.58 per KwH, or fully $0.50 above the price paid for the fossil fuel base load.  At this subsidy level, the US would be paying $400 billion a year in subsidies and/or higher prices.

First Solar has grown at over 150% per year for the last 3 years so the 30% assumption above is conservative, as is the assumption about the number of competitors doubling every two years.

Another interesting note - First Solar makes a pre-tax margin around 33% of sales, which is over 6x larger than health insurance companies make (and are excoriated for).  Is it any wonder Germany no longer wants to keep subsidizing First Solar's bottom line to levels far above most equipment manufacturing companies.

Bring it On

Bloom Energy is introducing what looks like a 200kW fuel cell that runs on natural gas for about $700,000.  That compares pretty favorably with the current cost of at least $2,000 per KW to build a coal plant, especially when one factors in reduced distribution and pollution costs.  We have gobs of natural gas and are finding more all the time, and (unlike something like hydrogen) the distribution and storage infrastructure is already in place.  Hope it works.

I often critique new energy technologies here, and that critique is often confused with a hostility to new technologies.  This is far from the case.  Living here in Phoenix, I would love to have cheap solar cells to spread over my roof like carpet.  What I am opposed to is government subsidies for technologies that are not even close to economic compared to current alternatives.   I don't know the Bloom business model  (I am suspicious they have a large rent-seeking component if KP is funding them) but if they can make these work subsidy free, that's great.

Like Me Choreographing a Ballet

I often respond to various articles that a group of politicians are going to create a strategic plan** for the local economy that this is similar to my trying to choreograph a ballet .  TJIC has similar words for this effort:

Governor Deval Patrick and Senate President Therese Murray plan to propose this week several ways to improve the Bay State's business climate, saying they need to be more aggressive in steering the region out of its economic malaise.

Both have lifelong careers in non-business sectors (government, academia, journalism, legal, non-profit).  TJIC responds:

Asking them to design programs to better the business climate is about like asking me to design menstrual pads "“ I don't understand the sector, I don't understand the features, I don't understand the problems, and there's no way that the effects of my work will ever come back to make an impact on me.

This is reminiscent of this great comment from Kevin Williamson  via Instapundit

The good news is that, when it comes to reshaping the U.S. mortgage market [any market for that matter "” ed.], the Obama administration's top guns are bringing to bear all of the brisk, rough-'n'-ready entrepreneurial know-how they picked up in their previous careers as university professors, nonprofit activists, and holders of political sinecures.

But we are spending more and more to get this "expertise", as documented in a depressing post at Carpe Diem on the growth of government employment and salaries.  One chart out of many:

fedemp

** Footnote:  About once a month we get some group lamenting that Phoenix has no master plan to create some kind of economic focus for itself.  One of the hilarious things about this is that if you go back and look, about half of the past proposals have Phoenix focusing on some super-hot industry (e.g. semiconductor manufacturing, e-commerce) that is just about to crash.  Lately, everyone has decided that Phoenix should be the center of the solar industry, because, uh, we have a lot of sun, without any particular explanation of why having a lot of sun should be an advantage in precision manufacturing and assembly of solar components.  But we are shelling out all kinds of tax breaks and subsidies for these companies to come here.  My prediction - solar will be the next ethanol.  In ethanol, increases in government subsidies caused a lot of manufacturing capacity to be built.  But subsidies could not grow as fast as capacity, and a glut resulted in a huge shakeout.  The solar boom will occur when a technology is perfected that makes solar economic without subsidies.  When that occurs, I will be the first in line to cover my roof in the new tech.

In Search of Skepticism

PHP4B5A1EED0E9E1Why can't our newspaper here in Arizona apply any skepticism to alternate energy technologies?  Sure, I think this technology is cool, where large solar dishes concentrate heat on what appears to be Stirling cycle engines  (the article, true to form, does not explain the technology, but a few hints plus the name of the company "Stirling Energy Systems" seems to point to that answer).  Other concentrator technologies focus on boiling water, so this a new approach to me.

However, why can't the article actually address real issues, like "how does this technology stack up, based on cost and efficiency, vs. other solar technologies."  It says it uses less water than other concentrator technologies, but is it more or less efficient?  No answer.

We can figure a few things out.  First, as with many "renewable" energy technologies, the company selling it engages in nameplate capacity abuse.  A 1MW coal plant produces 1MW all day long.  A 1MW wind plant produces 1MW when the wind is blowing hard, and less at other times.  And a solar plant produces 1MW when the sun is at its peak.   We can address this latter because folks have calculated sun equivalent hours, the number equivalent max sun-hours per day a site gets through the year.  For the best desert sites in the US, this number is around 6.  This means that the actual capacity of this plant is not 1.5MW, as stated in the article, but about a fourth of that, or  0.375MW.

This matters for a couple of reasons.  They state their build cost as $2.8 million per MW, which seems competitive to coal plants which cost $1.0-2.0 per MW, but in fact the reference number for this solar based on an apples to apples capacity comparison is actually  $11.2 million per MW.   The solar plant gets some credit for having no fuel costs, so it might be possible still for its power to be competitive, but it appears form the limited information in the article that it is not:

Singleton would not disclose what SRP will pay for the electricity, but said the utility will pay a premium for the environmental benefits of the power, and that the price is competitive with other sustainable-energy sources such as wind and geothermal power.

In other words, it is not competitive, so much so that they will not even reveal the price, and only subsidies and government mandates make it possible for a power company to buy the power.

Let's do a reality check.  At best, they get 8 dishes per acre, and 25Kw per dish at max sun.  So this is 8 x 25 x 6/24 = 50Kw per acre.   Lets say we want to get rid of coal.  The US generating capacity of coal plants is about 336,000 MW, or 336,000,000 KW.  To replace it with this solar technology would require 6,720,000 acres (10,500 sq miles or 10% of the state of Arizona) and cost $3.76 trillion dollars if located in the best possible solar areas.   This is not cheap but is not awful.

If I am doing the math right, I get something like $70,000 per dish   (1 dish = 25Kw, $2.8 million per MW).  I would think there are a lot of rich folks with some acreage that would pay $70,000 for one of these bad boys.  It would look much cooler than solar panels on the roof.

Wherein I Actually Agree with Dianne Feinstein

A lot of climate skeptic sites are jumping on the apparent irony of this story:

Senator Dianne Feinstein introduced legislation in Congress on Monday to protect a million acres of the Mojave Desert in California by scuttling some 13 big solar plants and wind farms planned for the region.

But before the bill to create two new Mojave national monuments has even had its first hearing, the California Democrat has largely achieved her aim. Regardless of the legislation's fate, her opposition means that few if any power plants are likely to be built in the monument area, a complication in California's effort to achieve its aggressive goals for renewable energy.

I think that there is an important lesson here that even "clean" energy sources have environmental downsides.  Its funny how things come full circle - thirty years ago I used to argue with people who had obsessive concerns about nuclear waste.  I would say that the volume of waste was really small, and in fact coal and oil were no different in that they generated a lot of waste but that they spewed their waste all over the atmosphere -- at least nuclear waste was compact and defined and easy to store.

Anyway, I actually think Feinstein is correct here.   Here is the origin of the plot of land:

For Mrs. Feinstein, creation of the Mojave national monuments would make good on a promise by the government a decade ago to protect desert land donated by an environmental group that had acquired the property from the Catellus Development Corporation.

"The Catellus lands were purchased with nearly $45 million in private funds and $18 million in federal funds and donated to the federal government for the purpose of conservation, and that commitment must be upheld. Period," Mrs. Feinstein said in a statement.

I have some bias in this, because my personal charities of choice tend to be private land trusts, that use private funds to buy lands for conservation.   I have always argued from an individual liberty angle that people who want land conserved shouldn't be demanding that government take it, they should be putting their money where their mouth is and helping to buy the land.  This story actually gives me another argument, because you can see that the private conservation buyers made a mistake in giving it to the Feds.  The Bush Administration, looking to score a PR victory in the alternative energy front, reneged on the promised conservation and committed the land to solar projects.

Green Fraud

Via Anthony Watt, from the Oregonian

State officials deliberately underestimated the cost of Gov. Ted Kulongoski's plan to lure green energy companies to Oregon with big taxpayer subsidies, resulting in a program that cost 40 times more than unsuspecting lawmakers were told, an investigation by The Oregonian shows.

Records also show that the program, a favorite of Kulongoski's known as the Business Energy Tax Credit, has given millions of dollars to failed companies while voters are being asked to raise income taxes because the state budget doesn't have enough to pay for schools and other programs....

According to documents obtained under Oregon's public records law, agency officials estimated in a Nov. 16, 2006, spreadsheet that expanding the tax credits would cost taxpayers an additional $13 million in 2007-09. But after a series of scratch-outs and scribbled notes, a new spreadsheet pared the cost to $1.8 million. And when energy officials handed their final estimate to the Legislature in February 2007, they pegged the added cost at just $1.2 million for the first two years and $4.1 million for 2009-11.

The higher estimates were never shown to lawmakers. Current and former energy staffers acknowledged a clear attempt to minimize the cost of the subsidies.

"I remember that discussion. Everyone was saying, yes, this is going to be a huge (budget) hit," recalled Charles Stephens, a former analyst for the Energy Department who left in 2006. "The governor's office was saying, 'No, we need a smaller number.'"

Hmm, sounds eerily like what is going on with the health care bill in Congress.

Update: It turns out that all of the "green" companies so far have sold their tax credits for cash to companies like Wal-Mart and US Bank.  This is no enormous problem (though the optics are terrible for the state) but it is yet another reason why the Oregon budget gets busted by this program -- a startup solar company won't use tax credits for years as it will take some time to be profitable (if they ever are) but Wal-Mart can use them right now.

The Cost of Solar

I had wanted to dig into the costs of a Florida solar facility that Obama recently visited.  Fortunately Ronald Bailey does it for us:

Now let's do a rough calculation of the costs of DeSoto Solar versus conventional power sources. According to the Electric Power Research Insitute, a modern 1,000 megawatt coal plant without carbon capture technology would cost about $2.8 billion to build. Adding carbon capture would boost the cost to as much as $4.7 billion.

The 25 megawatt DeSoto facility cost $150 million. Scaling it up to 1,000 megawatts would cost $6 billion. But coal power plants operate 90 percent of the time snd solar only 30 percent, so in order to get the equivalent amount of electricity out of solar plant would mean tripling the capital cost for a total of about $18 billion. In other words, building a solar power plant costs between 4- and 6-times more than conventional, or even carbon capture, power. Even worse, a scaled up DeSoto-style plant costs 18-times more than a natural gas plant.

Window Repair Jobs

Tyler Cowen links to a good article that gets at the fallacy that suddenly obsoleting our energy infrastructure and having to rebuild it will be of net economic benefit.

Optimistically treating European Commission partially funded data, we find that for every renewable energy job that the State manages to finance, Spain's experience cited by President Obama as a model reveals with high confidence, by two different methods, that the U.S. should expect a loss of at least 2.2 jobs on average, or about 9 jobs lost for every 4 created, to which we have to add those jobs that non-subsidized investments with the same resources would have created

Includes 1 million euros in government subsidies per wind job created.

In my mind, the green jobs mantra is a result of the CO2 abatement case becoming fatally weak, with supporters of legislation casting about for other justificaitons.  From the very beginning, many of the most passionate folks are on the AGW bandwagon not because they really understand the science, but because the theory provided justification for a range of government actions (reduced growth, limited technology, reduced energy use, reduction in global trade -- even vegetarianism) that they supported long before AGW made the news.

Update: A quick note on a theme I harp on a lot - nameplate capacity for wind and solar is really, really misleading.  In Spain in the study cited, wind operates at 19% of nameplate over the course of a year and solar operates at 8% (figure 3).  The actual CO2 reduction is even worse, because, particularly for wind, fossil-fuel fired turbines have to be spinning on hot backup for when wind suddenly dies.  Germany, the largest wind user in the word, found only 1,000MW of reduced fossil fuel plant needs from every 24,000 MW of wind capacity.

Your Idea Sucks -- Here's Your Money

Having read this:

In his proposed budget for 2010, Chu wanted $480 million to start eight Energy Innovation Hubs, or "Bell Lablets," as he called them, to stimulate research in areas ranging from solar energy to new materials for the electric grid. Each would receive $35 million to get started, and $25 million more in each of the following 4 years.

Last week Congress poured semi-cold water on the idea....Its skepticism was no surprise, having been included this summer in reports accompanying the spending bills in the House of Representatives and Senate (House, Senate versions). In August, Science reporter Jeffrey Mervis described how Chu admitted to a mediocre job of selling the idea and overcoming congressional concerns that the concept was poorly thought out and not well-coordinated with other energy research at the Department of Energy. House appropriators were particularly unkind to the idea, noting:

A new set of centers with overlapping research goals risks adding confusion and redundancy to the existing fleet of research and development initiatives

So since everyone agreed it was a bad idea, they killed it right? Ha ha, cute idea, actually voting and spending money based on efficacy. In fact, they gave Chu quite a bit

Conferees to the Energy and Water spending bill approved funding for three of the centers, two in energy efficiency and renewable energy and one in nuclear energy.

If they really make no sense, how about "zero"

This Looks Very Good

We Phoenicians, who live in one of the best solar sites in the world, have been anxiously awaiting a solar electric technology that makes economic sense.    I have a couple thousand square feet of nice, flat room that is just begging to get be off the grid.  Already, solar is economic for individuals in Phoenix, but only if you are willing to soak American taxpayers and your neighbors for 85% of the costs.  It would be nice if it were, you know, actually economic and not just subsidy bait for tens of thousands of dollars.  I have dug into many analyses that claim that solar has a 5-7 year payback, but never seen one that achieved these returns without substantial subsidies and rebates (beware the term "energy payback" which is not the same thing as investment payback (pdf))

For a while I have said that I thought traditional silicon/germanium IC-like wafer processes for making solar cells was just never going to get there, and that some other technology was necessary.   This might be one such example:

JA Solar, one of the big players in the solar industry, is working with Innovalight to commercialize the latter's method for making silicon-ink-based, high-efficiency solar cells, the companies said this week.

... The solar cells are created by pouring an ink solution incorporated with silicon nanoparticles and then decanting the excess liquid to leave behind a crystalline silicon structure.

At the time of the 2007 announcement, Sunnyvale, Calif.-based Innovalight claimed its method not only resulted in solar cells that were cheaper to produce by as much as half, but that the crystalline structure resulting from the process made its cells more efficient at converting electricity.

Those claims now appear to be validated.

On Tuesday, Innovalight announced that an independent study of its method by the U.S. Department of Energy's National Renewable Energy Laboratory and the Fraunhofer Institute for Solar Energy Systems in Germany confirmed that its silicon ink-based cells "demonstrated a record 18 percent conversion of efficiency."

The 18% conversion efficiency is close to a record for thin films, but must be the "record" for production models, since higher conversions have been achieved in the lab.  18% is very good for a production device, particularly if it is cheaper to manufacture than current cells.

Solar Economics: Would You Pull A Lever to Get $12,000 if Somewhere in Massachusetts a Person Lost $58,000?

With articles about solar prices coming down, and living in Phoenix (one of the best solar sites in America), I yet again have priced out solar for our home.  The short answer is that it makes sense, IF you don't mind reaching into the pockets of all your neighbors.

For this analysis, I will use the prices here.  The $72,167 cost for a 11.76kW system is pretty competitive at $6.13 per watt installed  (this is rated watts, not actual -- see footnote).  The panels themselves can be bought for about $3 per watt, with about $1 a watt for other equipment like inverters and $2 per watt for installation.  Do-it-yourself packages for a similar size system are here and go for around $4-$4.50 per watt.

The solar company estimates that this system in Phoenix will save me$2,779 a year on my electric bill.  I have not checked their math, but I assume they are not under-estimating this number in their marketing literature.  Taking this savings, we get a payback on the installation of about 26 years.   This ignores future electricity price increases, but also ignores the time value of money.  At 8% over 20 years, it has a net present value of  NEGATIVE $41,558.   At the end of the day, this is a terrible return -- in fact a huge value destruction.

But I began this post saying a solar investment might make sense.  How?  Well, that is where your willingness to reach into your neighbor's pocket comes in.  Our solar company estimates the following tax breaks and rebates on the system described above:

  • Utility rebate:  $35,280
  • State income tax credit: $1,000
  • Federal income tax credit:  $21,650

So, in building this $72,167 improvement on my house, I get to use $57,930 of other peoples' money**.  As Steve Martin says in the Jerk:  "That takes the pressure off!"

Like in many other cases, other peoples' money suddenly makes solar a good investment.  Now we are looking at $2,779 a year in savings from a net investment of $14,237, or about a five year payback.    Over 20 years even assuming no inflation and an 8% cost of money that has an NPV of $12,081.

So -- I officially reverse my past conclusions that home solar does not pay.  It can in fact be a good investment -- for you.  For the country, it is a terrible investment.   Your neighbors are contributing $57,930 in subsidies while you receive just $12,081 in benefits.  The remainder, just over $45,000, is a dead-weight loss to the economy.  It is money destroyed by the government.

This is surprisingly like the ethics problem of pulling a lever to get a million dollars but someone you don't know in China dies.  The only difference is that you get $12,000 and someone you don't know loses $58,000.

** Footnote: Yeah, I know, theoretically the utility rebate is a substitute for the capital spending and not a wealth transfer.  But trust me, it's a wealth transfer.  To understand this, we have to shift from rated solar watts to actual capacity in watts.  In Phoenix, one of the best solar sites in the world, panels produce only about 25% of their rated capacity in a day (6 equivalent sun hours per day divided by 24 total hours in a day).  So, on average, a 100 watt panel is producing 25 watts.

This means that by APS paying about $3 per rated watt in rebates, they are paying about $12 per actual watt.  And there is no way this is what they are paying for other capacity.  A typical brand new power plant might be $2-$3.50 per watt.  So at $12, this is clearly a transfer mandated by the PUC, and not a smart substitute for capital expenditure.   Besides, if this payment made economic sense for the utility, there would not be an annual cap on the amount paid out.

As wealth transfers go, this is a particularly egregious one, as it tends to add costs to the electric bills of the poor and middle class so rich folks can build hobby solar systems so they can tell their friends at cocktail parties that they are "green."

Update: All of this is not to say that I am so good a person as to not take the money that is being put at my doorstep.  I'm still thinking about it.

What "Progressives" Are Really After, Part 2

Climate activist Adam Sacks at Grist:

We must leave behind 10,000 years of civilization; this may be the hardest collective task we've ever faced.  It has given us the intoxicating power to create planetary changes in 200 years that under natural cycles require hundreds of thousands or millions of years"”but none of the wisdom necessary to keep this Pandora's Box tightly shut.  We have to discover and re-discover other ways of living on earth.

We love our cars, our electricity, our iPods, our theme parks, our bananas, our Nikes, and our nukes, but we behave as if we understand nothing of the land and water and air that gives us life.  It is past time to think and act differently.

If we live at all, we will have to figure out how to live locally and sustainably.  Living locally means we are able get everything we need within walking (or animal riding) distance. We may eventually figure out sustainable ways of moving beyond those small circles to bring things home, but our track record isn't good and we'd better think it through very carefully.

Likewise, any technology has to be locally based, using local resources and accessible tools, renewable and non-toxic.  We have much re-thinking to do, and re-learning from our hunter-gatherer forebears who managed to survive for a couple of hundred thousand years in ways that we with our civilized blinders we can barely imagine or understand.

Yep, let's all return to that sustainable world of 8000BC, scrap the worldwide division of labor and all our technology, and go back to subsistance farming and travelling by horse.  Gee, what a happy time that was...

Interestingly, this guy is making an incredibly common failure among physical scientists -- the attempt to apply conservation of mass/energy physical models or bacteriological growth models to economic growth:

Endless growth is an impossibility in the physical world, always"”but always"”ending in overshot and collapse.  Collapse: with a bang or a whimper, most likely both.  We are already witnessing it, whether we choose to acknowledge it or not.Because of this civilization's obsession with growth, its demise is 100 percent predictable.  We simply cannot go on living this way. Our version of life on earth has come to an end.

Here is what I wrote, in a post titled "Physics, Wealth Creation, and Zero Sum Economics"

My guess is that this zero-sum thinking comes from our training and intuition about the physical world.  As we all learned back in high school, nature generally works in zero sums.  For example, in any bounded environment, no matter what goes on inside (short of nuclear fission) mass and energy are both conserved, as outlined by the first law of thermodynamics.  Energy may change form, like the potential energy from chemical bonds in gasoline being converted to heat and work via combustion, but its all still there somewhere.

In fact, given the second law of thermodynamics, the only change that will occur is that elements will end in a more disorganized, less useful form than when they started.  This notion of entropic decay also has a strong effect on economic thinking, as you will hear many of the same zero sum economics folks using the language of decay on human society.  Take folks like Paul Ehrlich (please).  All of there work is about decay:  Pollution getting worse, raw materials getting scarce, prices going up, economies crashing.  They see human society driven by entropic decline....

[But] the world, as a whole and in most of its individual parts, is wealthier than in was in 1900.  Vastly more wealthy.  Which I recognize can be disturbing to our intuition honed on the physical world.  I mean, where did the wealth come from?  Out of thin air?  How can that be?

Interestingly, in the 19th century, scientists faced a similar problem in the physical world in dating the age of the Earth.  There was evidence all around them (from fossils, rocks, etc) that the earth had to be hundreds of millions, perhaps billions of years old.  The processes of evolution Darwin described had to occur over untold millions of years.  Yet no one could accept an age over a few million for the solar system, because they couldn't figure out what could fuel the Sun for longer than that.  Every calculation they made showed that by any form of combustion they understood, the sun would burn out in, at most, a few tens of millions of years.  If the sun and earth was so old, where was all that energy coming from?  Out of thin air?

It was Einstein that solved the problem.  E=mc2 meant that there were new processes (e.g. fusion) where very tiny amounts of mass were converted to unreasonably large amounts of energy.  Amounts of energy so large that it tends to defy human intuition.  Here was an enormous, really huge source of potential energy that no one before even suspected.

Which gets me back to wealth.  To balance the wealth equation, there must be a huge reservoir out there of potential energy, or I guess you would call it potential wealth.  This source is the human mind.  All wealth flows from the human mind, and that source of energy is also unreasonably large, much larger than most people imagine.

Global Warming Alarmists Have Your Best Interests At Heart

Sent to me by a bunch of readers, from the Atlantic interview with Thomas Schelling:

I sometimes wish that we could have, over the next five or ten years, a lot of horrid things happening -- you know, like tornadoes in the Midwest and so forth -- that would get people very concerned about climate change. But I don't think that's going to happen.

This reminds me of a post from way back, when Kevin Drum wrote:

Seeking to shape legislation before Congress, three major energy trade
associations have shifted their stances and decided to back mandatory
federal curbs on carbon dioxide and other man-made emissions that could
accelerate climate change.

I responded:

Having some Washington lobbying organizations switch which side of this incredibly difficult trade off they support is not "good news."  Good news is finding out that this trade off may not be as stark as we think it is.  Good news is finding some new technology that reduces emissions and which private citizens are willing to adopt without government coercion (e.g. sheets of solar cells that can be run out of factories like carpet from Dalton, Georgia).  Or, good news is finding out that man's CO2 production has less of an effect on world climate than once thought.  Oddly enough, this latter category of good news, surely the best possible news we could get on the topic, is seldom treated as good news by global warming activists.  In fact, scientists with this message are called Holocaust deniers.

Postscript: It is particularly telling of a certain mindset that Schelling specifically wishes bad things to occur in the Midwest.   By most leftish standards, people in flyover country (except maybe Ohio since it is a key swing state) don't really count.

Over-Stating Our Ability to Adopt Renewables

All those confident in our ability to ramp up things like wind and solar quickly should take a long look at T. Boone Pickens decision to virtually abandon billions of investment in wind.

One of the ways I think our potential to increase renewables is over-stated is that the government has begun lumping hydro power into wind, as in these charts.  They show "renewables" as about 9% of electricity production.   Increasing this to, say, 20% seems daunting but doable - after all, we are just doubling it.

But in fact, almost all of the 9% is hydro power, and that is not going to increase (in fact environmental presure is actually to destroy several hyrdo facilities to allow the rivers to run free).  This means that to get total renewables to 20%, other renewables like wind and solar will have to increase from about 1% to 12%, or a twelve fold increase.  This is much more daunting, especially since a raft of subsidies and incentives and programs have gotten us to just 1%.

Postscript: Owning a home in Phoenix with a big flat roof, there is no one in the world rooting for solar to be economic more than I am.  I have run the numbers recently, and taking advantage of all government subsidies, the investment has about an 8-10 year payback.  It's just not there yet.  Further, I worry that the current silicon/germanium IC technologies are dated and dead end.  I fear that buying solar now is like buying the last IBM mainframe before PCs came out.  I have a ton of confidence in the innovativeness of man, and believe that a real solar breakthrough will occur in the next 10 years.  Wind, on the other hand, is never going to work.  It is the ethanol of electricity production.

Interest Grows for Receiving Government Handouts

The AZ Republic has an article today entitled, "Interest grows for solar plant at city landfill."  It is telling who is interested:

It's a sign of the growing interest in Arizona's renewable-energy market, as solar manufacturers, civil engineers, investors and attorneys showed enthusiasm for the $1 billion project

I am quite sure that a number of solar engineering firms and parts manufacturers are interested feeding off a billion dollar project.  Now, the article tries to anticipate my concern about this being a government pork-fest by saying the project "would be financed and built by the private sector."  This is an odd statement given this note a couple of paragraphs later:

That would help the solar company meet a strict deadline to apply for hundreds of millions of dollars in federal stimulus funds....

the economic-stimulus package provides grants of up to 30 percent of construction costs if companies can break ground by December 2010, said Brian Rasmussen of California-based BrightSource Energy Inc., a potential bidder.

So the billion dollars is privately financed, except for the real estate provided by the city and the $300 million in federal government funds and a gauranteed above-market subsidized purchase price for the power from the public utility plus any number of other government subsidies and incentives to be named later (such as government municipal bond financing).

Absolutely Inevitable

If you move solar panels out of the Arizona desert, they are going to produce less electricity.  You almost don't have to tell me where they are going -- if they are currently close to the optimal spot for maximum solar energy production, then moving them is bound to reduce their output.

Seems obvious, huh?  So why is it so difficult to understand that when the government moves capital and other resources away from the industries where the forces of market optimization have put it, output is going to go down.

Subsidizing renewable energy in the U.S. may destroy two jobs for every one created if Spain's experience with windmills and solar farms is any guide.

For every new position that depends on energy price supports, at least 2.2 jobs in other industries will disappear, according to a study from King Juan Carlos University in Madrid.

U.S. President Barack Obama's 2010 budget proposal contains about $20 billion in tax incentives for clean-energy programs. In Spain, where wind turbines provided 11 percent of power demand last year, generators earn rates as much as 11 times more for renewable energy compared with burning fossil fuels.

The premiums paid for solar, biomass, wave and wind power - - which are charged to consumers in their bills -- translated into a $774,000 cost for each Spanish "green job" created since 2000, said Gabriel Calzada, an economics professor at the university and author of the report.

"The loss of jobs could be greater if you account for the amount of lost industry that moves out of the country due to higher energy prices," he said in an interview.

We all know from reading the media that the Obama administration is 1) full of brilliant people way smarter than the rest of us and 2) driven by science.  So this insightful exchange between a reporter and White House spokesman Robert GIbbs vis a vis this Spanish study should come as no surprise:

Q: Back on the President's speech today, a Spanish professor, Gabriel [Calzada] Álvarez, says after conducting a study, that in his country, creating green jobs has actually cost more jobs than it has led to: 2.2 jobs lost, he says, for every job created. And he has issued a report that specifically warns the President not to try and follow Spain's example.

MR. GIBBS: It seems weird that we're importing wind turbine parts from Spain in order to build "” to meet renewable energy demand here if that were even remotely the case.

Q Is that a suggestion that his study is simply flat wrong?

MR. GIBBS: I haven't read the study, but I think, yes.

Q Well, then. (Laughter.)

In two sentences, Mr. Gibbs demonstrates that 1) He is an idiot and 2) He has no respect for science.  The correct, intelligent response would be "I can't comment, I have not read the study yet."  Mr. Gibbs does deserve credit for being an apparent master of the non-sequitur.  I have been trying to think of an eqivilent formulation.  The best I can come up with is to suppose someone said that "publicly funded sports stadiums generate no new economic activity and are just a taxpayer subsidy of sports owners, players, and ticket holders" and getting the response that  "how can this be when people still go to the games?"

I was afraid that all this braininess in the White House was going to eliminate the humor from Administration pronouncements but I see that won't be the case.

Q: What's The Fastest Way to Get 5 Million Green Jobs?

A:  Start with 10 million current jobs.

Kenneth Green argues that Obama's claim that obsoleting current infrastructure and requiring its replacement with new, greener infrastucture creates jobs is just the broken windows fallacy  (where have you heard anyone else say that?)

If Obama's energy promises rely on questionable science, they rely on even more questionable economics. We are to believe that replacing conventional energy sources (especially coal) with renewables (especially wind) will create 5 million new "green jobs." The hope is that armies of workers will be enlisted to build
tens of thousands of windmills; to manufacture and deploy solar-power installations; to harvest, transport, and process huge amounts of biofuel feedstock; and to string the power lines that will allow the U.S. power grid to incorporate a major expansion of intermittent energy.

Unfortunately, the idea of government "job creation" is a classic example of the broken window fallacy, which was explained by French economist Frédéric Bastiat way back in 1850. It is discouraging to think that nearly 160 years later, politicians still do not understand Bastiat's basic economic insight...

Now consider Obama's "green jobs" plan, which includes regulations, subsidies, and renewable-power mandates. The "broken windows" in this case would be lost jobs and lost capital in the coal, oil, gas, nuclear, and automobile industries. Currently, these industries directly employ more than 1 million people.
Conventional power plants would be closed, and massive amounts of energy infrastructure would be dismantled. After breaking these windows, the Obama plan would then create new jobs in the renewable
energy sector. The costs of replacing those windows would ultimately be passed on to taxpayers and energy consumers.

A Thought on Global Warming Action

Here is the hard truth for those of us who believe that, since CO2 has had little effect on global temperatures to date, expensive abatement plans will similarly have little if any measurable effect:  They are coming anyway.  It is actually probable that the Republicans could combine with heavy industrial states like Michigan in the Senate to block dramatic new legislation.  But President Obama already has the legal and legislative authority to enact sweeping and expensive CO2 mandates without going back to Congress. 

So with that depressing thought, here is a bit of good news:  The media may well come over to the skeptics' side soon, at least partially.  Here is why:  The media is extraordinarily loath to really challenge policy proposals in advance that are popular with the center-left.  They are even less likely to challenge said proposals when they touch on a story of doom.  There is nothing the media enjoys more than piling on a good public scare. 

But history has shown that the media will turn on these proposals once they are implemented, and sometimes quite soon after.  Remember ethanol subsidies?  The press were behind this crap all the way, until Congress passed enhanced subsidies a while back, and then the press suddenly starting "discovering" the effect on rising food prices, the environmental problems with land use, the ugliness of some of the subsidy politics, the fact that few scientists think corn ethanol will actually reduce CO2, etc.  Yeah, I know, all of this was entirely predictable (and predicted by many of us) in advance.  But this just seems to be how the media works.

Because the only thing the media loves more than fear-mongering a crisis that is 20-years away is fear-mongering one that is visibly upon us.  The press freaked at the California energy crisis a few years ago, peppering the public with stories of rising prices and rolling blackouts.  And what has happened since then?   Electricity demand has risen, no one can build electrical capacity, wind and solar are a joke, and Obama is only going to make it harder and more expensive to produce enough power (I think Obama's exact words were "bankrupt the coal industry.") 

Explaining Temperature History

I post most of my more detailed climate work over at my other blog.  But I wanted to repost here something I wrote in response to a number of request for a brief version of what is driving global temperatures.

My sense is that medium to long scale 20th century temperature trends can be explained mostly through three drivers:

1.  A cyclical variation driven by multi-decade oceanic cycles like the Pacific Decadal Oscillation (PDO):

pdo

2.  Changes in solar output, either directly as increased heating or indirectly via a variety of theories on things like cosmic rays and cloud formation:

sunspot

3.  A long term trend of up to +0.05C per decade that may include a CO2-warming component.

I am willing to posit a CO2 impact net of feedbacks of perhaps 0.5-1.0C over the next century.  This may appear low, but is the only scale of number reasonably supported by history.  Any higher number would result in temperatures way too high historically.  And even assuming a number this high runs into the following problem:  There was probably a trend of about this magnitude emerging from the little ice age 200+ years ago and extending into the 20th century.  You can see it in the glacier numbers below:  (source)

glacier

Those that want to assign the temperature trend, once the sun and the PDO are removed, post-1950 to CO2, need to explain what effect was causing the nearly exact same trend from 1800-1950, and why that trend conveniently switched off at the exact moment man's CO2 takes over.  In the context of the glacier chart, what was causing the glaciers to retreat in 1880, and why is that effect not the one at work today?

With evidence that the PDO has reversed to its cool phase and that the sun may be shifting into low gear, I think it is reasonable to posit warming no more than 0.5-1.0C over the next century.  For those who have not seen it, Roy Spencer has a new paper on the PDO, clouds and temperature history.   My video on why climate models overstate future warming through absurd assumptions of high positive feedbacks is here.

And a Pony

Jack Tapper of ABC list all of the goodies promised by Obama in just one stump speech.  The list is really staggering, even more so than the usual political BS.  It is way to long to excerpt here.  There are so many outrageous ones, its hard for me to even pick a favorite.  But here are a few good ones:

"eliminate the oil we import from the Middle East in 10 years"

Uh, right.  We are going to completely eliminate half the fuel coming into the economy in 10 years.

"lower premiums" for those who already have health insurance;... "end discrimination by insurance companies to the sick and those who need care the most";

Perfect.  We are going to prevent insurance companies from dong any risk management, we are going to pile on even more "must cover" rules for all kinds of crap from acupuncture to mental health, and by doing so we are going to lower premiums.

This may be my favorite, though:

"reopen old factories, old plants, to build solar panels, and wind turbines"

LOL.  Barack is going to open some of those old GM plants in Flint, Michigan and build solar panels.  Seriously, is this a rhetorical flourish or does he really believe that factories are generic production facilities that can make anything, kind of like those little buildings you make in an RTS?

Update: And if you think that voters just discount all this stuff, don't miss this video of Obama supporters talking about the free gas and house she is going to get.

By the way, none of this will push me to vote for McCain.  McCain promises all kinds of crazy stuff too, its just less compelling stuff to voters.   He is not losing because he is promising less -- I think he is losing because Obama has a better grasp of what expensive shit people want to be promised than does McCain.
