Obama Administration Is Not Helping The Gasoline User


The Obama administration current 5-year offshore drilling proposal will further block access to drilling on Federal lands.  Lets look available and blocked offshore drilling sites under Bush and under Obama.

OFFSHORE UNDER BUSH

OFFSHORE UNDER OBAMA

Maps and history of the Bush and Obama Administrations regarding offshore oil and gas can be read in more detail here.

Raising Onshore Oil Production Costs

In addition to restrictions, Bureau of Land Management Director Bob Abbey said last week at a Senate Appropriations Committee on Interior hearing that federal regulations applied to oil and gas development simply make it more expensive than producing on state or private land according to a posting on Institute for Energy Research website. Then he remarked that the Administration is currently considering raising onshore production royalty rates from 12.5% to the 18.75% that  is charged for offshore oil; in fact, he said that the Department of Interior’s upcoming budget depends on an assumed 50 percent increase in royalty rates.

More blocking of access and higher rates.  How is this helping the US consumer?

Pres. Obama Says US Only Has 2% Of World Oil. Can That Be Right?


Obama said:  “With only 2% of the world’s reserves, we can’t just drill our way to lower gas prices.  Not when we consume 20% of the world’s oil.”  Addressing the 2% part of his statement, if he meant we have only 2% of the “proven reserves” he is correct. But he uses this figure hoping that you will come to an incorrect conclusion. The US is, by every analysis one of the most energy rich nations in the world.   Others, including the Congressional Research Service, say that the US is the most energy rich nation in the world

The second part –consuming 20% of the world’s oil– is a non sequitur, meaning it does not follow logically from the previous part of his statement.  We will talk about that later.

The basis for the President’s statement came from the DOE’s Energy Information Administration.  The US’s “proven” reserves of 20.6 billion barrels of oil are equivalent to 2% of the worlds proven reserves.

DOE’s Energy Information Admin (EIA) Table of US Reserves (Billions of BBL’s) 10/19/2011

Region Proven Inferred Un-discovered Total TechnicallyRecoverable
Onshore 12.7 50.1 51.1 113.9
Offshore 4.3 10.3 42.7 57.4
Alaska 3.5 2.1 42.0 47.6
Total US 20.6 62.5 135.8 218.9

Interpreting the table, Proven reserves are where oil production is underway and the extent of the fields is well known.  Inferred is the volume by which the estimate of total recovery from a known crude reservoir or aggregation of such reservoirs is expected to increase during the time between discovery and permanent abandonment.  Undiscovered is oil that very likely exists, and can be recovered depending in part on technology and/or the price of oil.

This table understates the reserves.  EAI says of the above table: Resources in areas where drilling is officially prohibited are not included.  Estimates of the resources in the Northern Atlantic, Northern and Central Pacific and within a 50-mile buffer off the Mid and Southern Atlantic OCS are excluded from the technically recoverable volumes.  A case in point is that the reserves in ANWR which according to the USGS may contain 12 billion barrels is not included because the Feds have taken it off the table.   Most of our costal waters are off-limits as well.

This table also excludes the shale oil in the Green River Formation in Colorado, Utah and Wyoming. The Feds control roughly ¾ of the public lands on which fossil fuel resources exist. Wiki says that: “The Green River Formation contains the largest oil shale deposits in the world. The 213 billion tons of oil shale contain an estimated 2.38 × 10¹¹ m³ (1.5 trillion US barrels) of shale oil.

When the proven reserves are stated,  how should you interpret the number?  Here is an example from The Institute for Energy Research:

Proved Oil Reserves Are Not Static

Let’s take a look at history. In 1944, U.S. proven oil reserves were 20 billion barrels — about the same as they are today. Yet, between 1945 and 2010, the United States produced 167 billion barrels of oil. In other words, the United States produced over 8 times more oil than the amount of proven oil reserves it had in 1944.  How can that be? The answer is that proven oil reserves are not stagnant because people keep looking for oil. Proven oil reserves keep changing, are officially recorded every year, tallied country by country, and published in the Oil and Gas Journal, among other publications. And due to U.S. entrepreneurship and ingenuity, more reserves are found and proven each year.

What Does More Recent Data Look Like?

So, is this an historic anomaly? No. Let’s look at more recent data. In 1980, according to the Energy Information Administration, the United States had 31.3 billion barrels of proven oil reserves. However, between 1980 and 2010, the United States produced 77.8 billion barrels of oil and still had 20.7 billion barrels of oil reserves left. In other words, between 1980 and 2010, the United States produced 2.5 times the amount of oil as it has proven oil reserves in 1980.

The preceding illustrates that comparing the proven reserves to oil consumption is at least faulty and perhaps intended to misinform.

The President said that we can’t drill our way to lower prices when we  are the largest consumer.   Now I know that OPEC is the major force in setting the price of crude.   Even so, they are not immune to the laws of supply and demand.  They know that  a substantial excess of supply over demand will cause them to either curtail production within the Cartel  to rebalance supply and demand or the price will drop.  They also know that if they see widespread drilling being undertaken,  lowering the price of crude can cause some marginal production capacity to shutdown.

Every country that has shale oil, will be out there trying to achieve some piece of national security brought about by having their own oil.  So the over supply is likely to happen.  Ask the natural gas suppliers how well their prices have held up in recent years now that the shale natural gas is becoming oversupplied.   It will happen to OPEC too.  And the sooner the better.

Volt and Leaf February sales


The February sales numbers for Volt and Leaf are in.   Volt numbers were 1023 which bettered January sales of 603.    Leaf numbers were 478 which trailed January sales of 679.   Y-T-D  sales for Volt are 1,626 and Leaf 1,157.  Chevy’s 4 cylinder ICE sales were up 46 percent.  The Cruze, one of the GM 4cylinder line,  put up big numbers at 18,556 units in February.   The public is obviously moving to more fuel-efficient vehicles with gasoline prices skyrocketing.   But their choice continues to be the more affordable ICEs than the all-electrics or hybrids.

Germany Surrenders on Solar Power


The title of this blog is a direct lift from an American Thinker posting of the same name.   Bjorn Lomborg, the Skeptical Environmentalist reports that Germany once was proud to call themselves “photovoltaic world champion”.  But nation has found the solar-power subsidies are expensive and inefficient.  Accordingly Lomborg:’ Using solar, Germany is paying about $1,000 per ton of CO2 reduced. The current CO2price in Europe is $8. Germany could have cut 131 times as much CO2 for the same price. Instead, the Germans are wasting more than 99 cents of every euro that they plow into solar panels.”

The Germans are phasing out these subsidies over a 5 year period.

In the US, we need to get serious about stopping the handouts to the Friends of Obama too.

Ethanol Subsidies: Not Gone, Just Hidden a Little Better


Mother Jones, an organization with a very liberal viewpoint posted that the subsidies for ethanol fuel have expired but that this doesn’t trouble the ethanol fuel producers.  Kevin Drum authored the posting and I will let him tell you why.

A few years ago I called subsidies for corn ethanol “catastrophically idiotic.” And why not? Corn ethanol, it turns out, is actively worse for the environment than even gasoline. Farmers responded to the subsidies by reducing the amount of farmland used for food production, and this drove up the price of staple food worldwide.  At the end of last year, ethanol subsidies quietly expired and no one tried to extend them.

So why did the powerful corn ethanol lobby let it expire without an apparent fight? The answer lies in legislation known as the Renewable Fuel Standard (RFS), which creates government-guaranteed demand that keeps corn prices high and generates massive farm profits. Removing the tax credit but keeping the RFS is like scraping a little frosting from the ethanol-boondoggle cake.

The RFS mandates that at least 37 percent of the 2011-12 corn crop be converted to ethanol and blended with the gasoline that powers our cars…[As a result] the current price of corn on the Chicago Mercantile Exchange is about $6.50 per bushel—almost triple the pre-mandate level.

 You might not be aware that when the EPA does mpg ratings for new cars, they use gasoline that does not contain any ethanol.  Adding ethanol at 10% of the fuel mix, the energy in a gallon of fuel is about 96.7% of a fuel not containing ethanol.  Ethanol has less energy per gallon than normal unleaded gasoline.  So the MPG rating is probably just a bit high.    See

EV January Sales—Volt and Leaf Sales go South


GM is blaming the drop in Volt sales from 1529 units in December 2011 to 603 in January 2012 on a bad publicity regarding the battery fires that occurred when crash testing the vehicles.  Probably is a factor.   But the realization that the weak performance of the batteries during winter conditions may also have had a negative effect.  More so on the Leaf than the Volt as the Leaf has no IC engine to take over when the battery runs out of juice.  Leaf sales in December were 954 dropping to 676 in January.

Geothermal Energy–What’s Its Source?


What is the source of geothermal energy? According to Terrestial Energy, written by William Tucker, if you drill a 1000 feet (305 meters) deep hole, the temperature at the bottom of the hole is 16F (10C) higher than at the top.  Tucker says that the average temperature of the ground is 54F (11C) so the bottom of that hole would be 70F.

The Homestake Gold mine in Lead SD, discovered in 1876, produced 40 million ounces of gold and 9 million ounces of silver. At the time of its closure in 2002, the mine was more than 8000 feet below the surface   Based on Tucker’s formula, the temperature at the 8000 foot level would be around 180F unless cooling air was introduced. .  At one time, one of my relatives (by marriage) was the engineer responsible for keeping the temperature in the mine at a level that would allow people to work.  And his description of what was needed to do that was pretty impressive.

Tucker goes on to say: “At 80 miles down we hit the Mohorovicic Discontinuity, discovered by Yugoslav seismologist Andrija Mohorovicic in 1909. At this point the temperature reaches 900o C and rock turns to liquid “magma.” At 1500 miles deep the temperature rises to 3700o C and another discontinuity – the Gutenberg – marks the place where molten rock becomes pure iron and nickel. Below that tremendous pressures turn the iron core solid once again and temperatures reaching 7,000o C – hotter than the surface of the sun.”

He explains that the source of this heat energy as follows: “Some of it is due to gravitational forces. As the earth is pulled inward, some of this force is translated into heat. Another portion is residual heat from the earth’s formation. According to the commonly accepted theory, originally proposed by Immanuel Kant, the solar system precipitated out of a huge swirling dust cloud, where particles kept colliding with each other until they agglomerated into the sun and the planets.

In the later stages, this involved huge collisions among very large objects. These impacts generate large amounts of heat, some of which still remains in the earth’s core. Together gravitational forces and residual heat probably account for about 40 percent of the earth’s temperature – the exact figure has still not been determined.

The other half of the earth’s heat, however, comes from a remarkable diminutive source – the slow breakdown of two of the 90 elements, uranium and thorium. With 92 protons, uranium is the largest natural atom, while thorium (90) is the third largest. Because of their size, they are unstable, meaning they are “radioactive.”

The internal “binding energy” that overrides the mutual repulsion among positively charged protons is occasionally overcome itself. This releases large quantities of energy, which sets subatomic particles in motion, creating large amounts of heat. Incredibly, the slow breakdown of these two radioactive elements, uranium and thorium, is enough to raise the earth’s internal temperature beyond the level of the surface of the sun.”

Tucker draws some conclusions from this when he says: “Why don’t we just take the source of that heat – the uranium or thorium – bring it to the surface, and reproduce or even accelerate the process that produces this heat in a controlled environment?

This is what we do in a “nuclear reactor.”  “A nuclear reactor is nothing more than terrestrial energy brought to the surface. There is nothing sinful or diabolical about it. We are not defying the laws of nature. Rather, we are working with a process that already takes place in nature.”

Battery Charge Anxiety Worse Than Gas Gauge Anxiety-Leaf Stops 4X For Charging!!


My dear wife and I have travelled many miles by car. She is content having me do the driving.  However, I am, in her mind, careless about going by any gasoline station without filling up the tank. That is a bit of hyperbole but running out of gasoline is high on her list of things to never do.  Imagine if you will, how she would feel if we owned a Nissan Leaf and used it to drive from Knoxville Tennessee to Antioch, Tennessee, a distance of 182miles (293km).  The Nashville Tennessean reported on such a trip taken by Stephen Smith, Executive Director of the Southern Alliance for Clean Energy, along with his wife and son.  The trip took place on a cool day, about 35F (2C), primarily on Interstate 40.  Fast (30minutes) electric vehicle chargers have been installed at the Cracker Barrel Restaurant chain and they planned to use them as needed.  The 182-mile trip took 6 hours to complete.  It included 4 stops for recharging.

Quoting from the newspaper story:

Only problem was, the Leaf’s charge dropped more rapidly than promised. In what has to be a public relations disaster for Nissan, Smith’s EV was unable to travel no farther than 55 miles on any leg of the trip – and for the most part, much less. The company, and its government backers, proclaimed [5] the Leaf was “built to go 100 miles on a charge” (large print), with a footnoted disclaimer (small print) that it travels shorter distances (like, 70 miles) if the air conditioning or the heater is used. Turns out even that was an exaggeration.   A trip that should take – according to map Web sites – less than three hours, ended up lasting six hours for the Smiths because of all the stops they had to make. The approximate intervals where they paused for recharging were as follows:

  • Knoxville to Harriman: 45 miles
  • Harriman to Crossville: 31 miles
  • Crossville to Cookeville: 31 miles
  • Cookeville to Lebanon: 50 miles

Lebanon to destination in Antioch, just south of Nashville: 22 miles

“It was a little nerve wracking,” Stephen Smith told the Nashville-based newspaper. “I’m finding the range is not 100 percent accurate.”

A further quote from the article:

The Smiths’ experience echoed that of a Consumer Reports reviewer [2] and Los Angeles columnist Rob Eshman [3], who called his Leaf his “2011 Nissan Solyndra.” Eshman, editor-in-chief of The Jewish Journal, experienced the same gauge inaccuracies and range anxiety that came from traversing hills and mountains and the use of his air conditioning in hot, smoggy L.A. 

“My life now revolves around a near-constant calculation of how far I can drive before I’ll have to walk,” Eshman wrote. “The Nissan Leaf, I can report, is perfect if you don’t have enough anxiety in your life.”

Bonus geography question—- How many State of Tennessee towns are named ANTIOCH?    See below.

Makes you wonder how that ever happened.

DRIVING A VOLT IN WINTER


The Chevy Volt’s driving range is reduced by cold or hot weather. The EPA estimates the Chevy Volt can travel 35 miles on a fully charged battery according to an article written by Doug Wernert, Chevrolet VoltAge Community Manager.   This will vary due to the weather conditions he adds.   If it is cold, using the car heater and front window defrost will have a “high/maximum Impact” on the Volt’s range.  And of course, in hot weather the A/C unit has “high/maximum impact” on range.  (Do you have the feeling that the range estimates are often at odds with the last news release you read?)  Does the EPA account for the weather in their estimated fully charged battery range?  If not, then it would seem that 35 miles might only be good on optimal days, says 68F or something like that (no A/C, no heat) and would result in a lower figure for the rest of the time.   A chart that accompanied Wernert’s article listed some other activities that resulted in “high/maximum impact” on the range.  These are

High speeds (70+mph)

Aggressive Accelerations

Steep incline

So, no driving in the mountains with the pedal to the metal in cold weather.

Rare Earth Elements Background.


If you follow the alternative energy issues (windmills, solar cells, ethanol for fuel, etc) you have very likely encountered discussions about rare earth elements. This posting is designed to provide the reader a little background.    Rare earths are used in lights, batteries, motors, lasers, and many other electronic applications.  In addition some of them are used as oil refinery catalysts, in metal alloys and glass polishing and coloring applications just to mention a few non-electronic uses.  There are 17 rare earth elements on the periodic table.  What makes these metals rare is that they are not often found in concentrations that can be profitably mined.  According to Wikipedia, one of them “Cerium” is the 25th most abundant element in the Earth’s crust,  however they are widely dispersed.  China has the best mines in the world it would seem.  China sold these elements at prices low enough to shut down most of the other mines in the world.

The magnets that can be made from several of the elements are vastly more powerful that those made from cobalt, the previous best permanent magnet making metal. Two of the rare earths commonly used are Neodymium and Samarium.  They are alloyed with other metals to form permanent magnets.  These magnets are replacing non-rare earth alloy magnets in electric motor assemblies because of their magnetic field strength.  These rare earth alloy magnets can be made smaller to reduce weight and still create high magnetic flux for electric motors.  It is said that the magnetic attraction is so powerful that if your finger is between two of these magnets you will likely experience a fractured finger.

Pure Neodymium has a low Curie temperature so it is only magnetic at low temperatures. Above the Curie point it’s parallel alignment of the magnetic field lines become disordered and it loses its magnetism.  To overcome this problem, Neodymium is alloyed with boron and iron to make a permanent magnet that can operate up to approximately 300 C.  The rare earths are also vulnerable to corrosion.  This problem is resolved by plating.

Although Samarium has a higher Curie temperature, it plays a smaller role than Neodymium because it is more expensive and creates a weaker magnetic field.  It is commonly alloyed with Cobalt.

The price and geopolitics are playing a role in the use of rare earths.  According to a November 16, 2011 NYTimes article, the prices of rare earths are dropping:

International prices for some light rare earths, like cerium and lanthanum, used in the polishing of flat-screen televisions and the refining of oil, respectively, have fallen as much as two-thirds since August and are still dropping. Prices have declined by roughly one-third since then for highly magnetic rare earths, like neodymium, needed for products like smartphones, computers and large wind turbines.

A chart of the price versus time for Neodymium is shown below:

The price for Neodymium appears to be at about $350 per kilogram.

There are some geopolitical ramifications surrounding rare earths:  Again from the Times posting:

China mines 94 percent of the rare earth metals in the world. Through 2008, it supplied almost all of the global annual demand outside of China of 50,000 to 55,000 tons. But it cut export quotas to a little more than 30,000 tons last year and again this year and imposed steep export taxes, producing a shortage in the rest of the world.

Together with a two-month Chinese embargo on shipments to Japan during a territorial dispute a year ago, the trade restrictions and shortage resulted in prices outside China reaching as much as 15 times the level within China last winter. That created a big incentive for companies that use rare earths in their products to move factories to China or find alternatives.

The US had some working rare earth working mines before the advent of the Chinese.  I have read that one in California is planning to resume production now that the prices have reached a point where working the mine is economical.

Stay tuned.
