Book Review: Private Empire – ExxonMobil and American Power by Steve Coll
If you were expecting Private Empire, the latest book by two-time Pulitzer Prize winning author Steve
Coll, to serve as a hit piece on ExxonMobil (and 'Big Oil' in general) you’ll be somewhat disappointed.
For anyone unfamiliar with his previous work, Steve Coll’s
earlier books include the highly recommended Ghost
Wars, arguably the definitive geopolitical account of the activities of
the CIA and other national intelligence agencies in Afghanistan and Pakistan
from the time of the Soviet invasion up to the eve of the 9-11. Ghost Wars won the Pulitzer Prize in 2004
for general non-fiction and was one of the books a newly elected President
Barrack Obama was reported to be reading upon entering office.
Steve Coll describes in an interview with Charlie
Rose what lead him to want to write Private Empire and how his original idea for the book was to tell a broader story about the oil industry in the style of Daniel Yergin’s The Prize. He soon realized, however,
that he needed a central character and Exxon was for him the only logical
choice.
Coll’s portrait of Exxon begins in March 1989 with the Exxon
Valdez oil spill in Prince William Sound, Alaska, an event which made the
company the most reviled in the United Sates. The book’s timeline spans the
subsequent transformation of the company, which was led by CEO Lee “Iron Ass” Raymond, up
through its present day stewardship by current CEO Rex Tillerson. Along the way
we learn a great deal about Exxon, including its somewhat peculiar cult-like corporate
culture, its blockbuster merger with Mobil, its controversial stance and
efforts on global warning, the access it enjoyed to political leaders such as
Vice President Dick Cheney, its somewhat misleading approach to reporting oil
reserves, and the company’s record setting financial success. The book in fact
makes for a compelling business case study and students of business history,
strategy and management will find much of interest.
The most interesting sections of the book are the ones detailing ExxonMobil’s operations in some of the world’s most politically
unstable regions. ExxonMobil’s bread and butter business is to invest billions
of dollars drilling holes in the ground in countries like Equatorial Guinea and
Chad and then spend the next 30-40 years working to make sure that nothing
interrupts the company's return on investment. Coll’s account of the 2004 attempted coup
in Equatorial Guinea by a group of British and South African mercenaries, who were supported from some elements within the Spanish government, is one of the most fascinating
stories in the book.

The Great Hope - An Update on the Holy Grail of Clean, Limitless Energy
Good story from the Guardian on the state of fusion research here.
While economically viable fusion may be decades off at the current low relative level of investment, it's good to see the world's great geopolitical powers working together:

Was putting a man-on-the-moon peculiarly un-American?

Here's the key excerpt:
He (Kennedy) set out to make America’s achievements in space an emblem of national greatness, and the project succeeded. Yet it did not escape the notice of critics even at the time that this entailed an irony. The Apollo programme, which was summoned into being in order to demonstrate the superiority of the free-market system, succeeded by mobilising vast public resources within a centralised bureaucracy under government direction. In other words, it mimicked aspects of the very command economy it was designed to repudiate.
That may be why subsequent efforts to transfer the same fixity of purpose to broader spheres of peacetime endeavour have fallen short. If we can send a man to the moon, people ask, why can’t we [fill in the blank]? Lyndon Johnson tried to build a “great society”, but America is better at aeronautical engineering than social engineering. Mr Obama, pointing to competition from China, invokes a new “Sputnik moment” to justify bigger public investment in technology and infrastructure. It should not be a surprise that his appeals have gone unheeded. Putting a man on the moon was a brilliant achievement. But in some ways it was peculiarly un-American—almost, you might say, an aberration born out of the unique circumstances of the cold war. It is a reason to look back with pride, but not a pointer to the future.Barring a crisis or existential threat, are the prospects for the U.S. undertaking an ambitious, focussed transition to a sustainable energy based system, or an affordable healthcare system, extremely remote?
In short, was the U.S.'s Race to the Moon success, as The Economist puts it, a 'glorious one-off'?

Refreshingly Candid U.S. Senator Graham On Clean Tech, 'Polar Bear Politics', and Why Cap & Trade is DOA
![]() |
U.S. Senator Lindsay Graham |
Regardless, I highly encourage you to listen to this talk and Q&A from U.S. Senator Lindsay Graham. He speaks plainly about the the politics of climate change, what a big kick in the pants $5/gallon gasoline is for pols, and how the U.S. can prevent being left behind by China in the race to develop next generation clean technologies.
For more about Graham here is a NY Times Magazine piece from last year, and below is his bio:
Lindsey O. Graham was elected to serve as United States Senator on November 5, 2002. He serves on five committees in the U.S. Senate: Appropriations, Armed Services, Aging, Budget and Judiciary. A native South Carolinian, Graham grew up in Central, graduated from D.W. Daniel High School, and earned his undergraduate and law degrees from the University of South Carolina in Columbia. Graham logged six-and-a-half years of service on active duty as an Air Force lawyer. From 1984-1988, he was assigned overseas and served at Rhein Mein Air Force Base in Germany. Upon leaving the active duty Air Force in 1989, Graham joined the South Carolina Air National Guard where he served until his election to the U.S. House of Representatives in 1994. During the first Gulf War, Graham was called to active duty and served state-side at McEntire Air National Guard Base as Staff Judge Advocate. He received a commendation medal for his service at McEntire. Since 1995, Graham has continued to serve his country in the U.S. Air Force Reserves and is one of only three U.S. Senators currently serving in the Guard or Reserves. He is a colonel and is assigned as a Senior Instructor at the Air Force JAG School.

Video: On Why Becoming More Energy Efficient is Simply Not Good Enough
"Like salt, we need to strip oil of its strategic importance."
-Gal Luft, Executive Director of the Institute for the Analysis of Global Security and a founder of the Set America Free Coalition
As Luft points out in this brief video the buzzterm 'energy independence' cannot simply be achieved in the U.S. by more domestic drilling for oil in areas such as the ANWR.
The word 'independence' implies choice, and when it comes to an energy source for automobiles the vast majority effectively have zero choice.
For a long time now oil has had a monopoly as THE energy source used in vehicle transportation, and we must find a way to put an end to oil's stranglehold.
Luft's and coauthor Anne Korin's book, titled Turning Oil into Salt: Energy Independence Through Fuel Choice, argues for the importance of making oil as un-strategic a commodity as salt has become.
Many have forgotten or never learned that wars used to be fought over salt. The 'primordial condiment' as some have called it was one of the most effective ways to preserve food, making it perhaps the world's most strategic commodity.

The Key Reason Electric Vehicles Matter
While most of a recent Seeking Alpha article titled 'Plug-in Vehicles and Their Dirty Little Secret' with 444 comments and counting is correct, there's a lot more to the electric vehicle story than the author's focus on emissions would lead the reader to believe.
EV Emissions and the Present and Future Grid
From an emissions perspective, running your car on electricity is about 25% cleaner than a standard car that gets about 25 mpg. But compared to a hybrid that gets more like 45-50 mpg, electric cars produce more emissions (e.g., carbon).
It's also true that more charging will likely occur at night, when the power produced is more heavily coal-weighted. However, while charging at night is worse from an emissions perspective it is much better from a grid stability and grid transmission perspective.
It's also worth noting that the mix of generation sources that provide power to the grid is changing - it is getting cleaner. Coal's share of the gird (in the U.S.) has gone from ~55% in the late 1980s to ~45% today. This trend will continue, especially as the U.S. continues to retire many of its older coal plants and replaces them with natural gas power plants, and more wind/solar.
The Environmental Protection Agency continues to tighten emissions regulations on power plants, so even newer coal plants (the few that will get built) are much cleaner and more efficient than the current ones. So using today's grid mix in assessing EVs ignores the improvement in emissions we'll be seeing in the future as the grid becomes cleaner.
How Much Do Electric Cars Really Cost?
There is one misleading remark the author makes on cost: in many cases running your car on electricity is actually cheaper than gasoline. $3.00/gal gasoline for a car that gets 30 mpg = $0.10/mile. If that car ran on electricity, it would get about 3 miles / kWh, and so for an electricity cost of $0.12/kWh (the US average), that works out to only $0.04/mile, or 60% less.
But this is only one example. Californians pay a lot for electricity, so it could be more expensive to run the car on electricity. Note: PG&E is working on rate structures that make it cheaper to charge at night, thus helping improve the economics for electric cars.
However, the cost of battery packs is expensive, so if you amortize the cost of the battery pack over the lifetime mileage of the pack, then that cost/mile obviously goes up for EVs. But is it really fair to do that? Do we similarly amortize the cost of a gasoline engine, fuel system, tank, etc? No. But without question, these battery packs are expensive, so the costs of the cars will be higher.
Why Electric Vehicles Truly Matter
So what's really behind all this fuss about rechargeable cars? If it's not about saving money, and not about reducing emissions, then what's left?
Energy security.
The biggest challenge our worldwide energy system faces is the near complete monopoly that oil has on the transportation sector. We heat our homes using a variety of energy sources. We make electricity using a variety of energy sources. But when it comes to the 3rd category of energy consumption (transportation) it is essentially all oil.
And making things worse is the fact that the U.S. imports about 2/3 of its oil, and 40% of those imports come from OPEC. This is not a very encouraging situation for whole host of reasons and warrants a separate article.
Hybrids help reduce oil consumption, which is obviously good for reducing emissions, fuel costs, and it helps reduce dependence on oil imports. But it does little to break oil's monopoly on the auto and overall transportation sector.
We need to find alternatives to oil, and the longer we wait the more painful it will become.

Video: Better Place CEO Shai Agassi on Charlie Rose
Perhaps one of the more interesting and ambitious startups of recent years is Better Place, which is working to the build global infrastructure necessary to support the widespread use of electric vehicles. The San Francisco Bay Area, Japan, and Israel among some of the locations which have already begun to employ Better Place's electric vehicle infrastructure.
Many of the world's fundamental environmental, economic and geopolitical challenges are due to the heavy reliance on oil as source of energy. There is very little hope of ending the U.S.'s dependence on foreign oil imports until alternative transportation infrastructure, like Better Place and Nissan's new Leaf electric car, are widely available. The effort to create this infrastructure is one of the most important and ambitious undertakings underway today.
For more information about Better Place check out CEO Shai Agassi's recent interview on Charlie Rose.
