 Those who visit my blog regularly know that I love charts and graphs. Below is a Sankey diagram produced by Lawrence Livermore Labs for the Department of Energy.  Sankey diagrams are named after Irish Captain Matthew Henry Phineas Riall Sankey, who used this type of diagram in 1898 in a publication on the energy efficiency of a steam engine.  The diagram below may also be viewed here.   

In the diagram, sources of energy are on the left, uses of energy are on the right. The first remarkable thing that struck me is how much energy is “rejected.” Most of the petroleum used in transportation, and most of the fuel used to generate electricity, is rejected. A huge loss by inefficiency. Avoiding even a small amount of this inefficiency would in effect create a new source of energy.

Note also the small contributions of renewable energy sources — biomass, solar, hydro and wind — to the total. And the as-yet very small contribution of natural gas to the consumption of energy for transportation.

A study written by J. David Hughes and published in February by the Post Carbon Institute claims that shale gas reserves are vastly overstated. “Drill Baby Drill – Can Unconventional Fuels Usher In a New Era of Energy Abundance?”  A companion article by Deborah Rogers claims that the shale “frenzy” is a Wall-Street-created bubble, that “U.S. shale gas and shale oil reserves have been overestimated by a minimum of 100% and by as much as 400-500% by operators according to actual well production data filed in various states,” and that “shale oil wells are following the same steep decline rates and poor recovery efficiency observed in shale gas wells.” “Shale and Wall Street: Was the Decline in Natural Gas Prices Orchestrated?” Both are published on a website called shalebubble.org.  These nay-sayers are continuing a tradition that has followed the oil and gas industry for decades – the debate between the peak-oil advocates and those who believe we will never run out of fossil fuels.

David Hughes’ study is worth reading. He studied more than 60,000 shale wells in the US and their rates of decline, costs and reserves. Hughes concludes that more than 1,542 wells will have to be drilled each year in the Bakken and Eagle Ford plays just to maintain current production, at a cost of $14 billion per year. He estimates that it will take $42 billion and more than 7,000 wells per year to maintain current levels of production of shale gas, whereas the value of the gas produced in 2012 was only $32.5 billion. Some examples from Hughes’ study:

Here are two good websites that provide interesting and balanced views about energy production and consumption:  The Rational Middle, and Think Progress. The Rational Middle is a series of films by the people that produced the movie Haynesville – A Nation’s Hunt for an Energy Future. Its goal is to encourage rational thinking about our energy future and establishing achievable goals toward sustainable energy. The films about unconventional resources and the risks of hydraulic fracturing are worth looking at.

 

Think Progress’s climate page introduces thought-provoking statistics about our nation’s energy sources and uses. For example:

56.2% of the nation’s energy is wasted each year – from the Lawrence Livermore National Laboratory:

I recently had the opportunity to view a documentary, “Switch,” produced by Dr. Scott Tinker, Director of the Bureau of Economic Geology at the University of Texas and the State Geologist of Texas, and Harry Lynch, documentary filmmaker. Dr. Tinker uses as the premise for his film the question – When will the world ultimately switch from fossil fuels to cleaner, alternative energy sources? In the process, he examines the sources and uses of energy worldwide, their costs and benefits, in an engaging film that takes him from the huge open-pit coal mines in Wyoming to offshore oil rigs to a hydraulic energy plant in the Netherlands, from the top of a wind turban to solar energy farms, and from driving Tesla to installing more efficient heating and lighting systems in the home. In the process, he does what no film I have seen does — provide a balanced, informed view of the role of energy in our modern world and where we are heading.

In addition to the film, Dr. Tinker has created a website, http://www.switchenergyproject.com/ , that provides additional short videos and other resources to further explore questions surrounding energy, including carbon capture, global warming, hydraulic fracturing, and alternative energy technologies. He interviews many world experts on global energy issues. The five energy issues you need to know, according to Dr. Tinker:

1. Energy drives the modern world and underpins every other issue.

We’re in the crazy election season once again, and once again all candidates have promised “energy independence.” Newt Gingrich promised to lower gasoline prices. President Obama takes credit for low natural gas prices. Governor Romney says we can eliminate imports of crude oil. Presidential candidates have promised energy independence ever since the oil embargo in Jimmy Carter’s administration. The candidates know that, in fact, government policies have little to do with energy prices, and there is little they can do to influence those prices. It might be good to look at a little history.

First, natural gas prices are still essentially a domestic phenomenon. Although transportation of liquefied natural gas is beginning, it is still very expensive in comparison to domestic prices. And natural gas prices are still essentially a matter of domestic supply and demand. Consider these graphs:

Prices for natural gas spiked in the last decade; production increased; and prices declined. Supply and demand.

A new documentary by Scott Tinker and Harry Lynch is now being rolled out at select screenings. http://www.switchenergyproject.com/aboutfilm.php#about Dr. Tinker was Director of the Bureau of Economic Geology, a joint organization of the University of Texas and the State of Texas, and a professor at UT’s Jackson School of Geology, as well as the State Geologist of Texas. Their film has won the award as best film at the Colorado Environmental Film Festival, and other film recognition. It is now being screened at selected cities across the country, and in Canada and Australia. I have heard Dr. Tinker speak, and he has a wide knowledge of energy issues. The film took three years to make. There are other good films at the Switch Energy Project website: http://www.switchenergyproject.com/topics/alltopics

Be sure to see the film if you get a chance.

Rolling Stone magazine’s Jeff Goodell has weighed in on the debate over natural gas reserves, the safety of hydraulic fracturing, global warming, methane groundwater contamination, and Chesapeake Energy’s controversial finances, in an article titled “The Big Fracking Bubble: The Scam Behind the Gas Boom.” Goodell pulled no punches. He calls Aubrey McClendon, Chesapeake’s CEO, “an influential right-wing power broker.” He says that “Fracking, it turns out, is about producing cheap energy the same way the mortgage crisis was about helping realize the dreams of middle-class homeowners.” He claims that “for Chesapeake, the primary profit in fracking comes not from selling the gas itself, but from buying and flipping the land that contains the gas,” and that Chesapeake “has more in common with Enron than ExxonMobil.”

Goodell’s article covers ground that is not new in the debate over the safety, ecology and economics of hydraulic fracturing. He touches on the study by Anthony Engraffea at Cornell University on whether natural gas has less global-warming effect than coal. He discusses the Duke University study of methane in water wells in Pennsylvania. He quotes Arthur Berman (Berman says miss-quoted), a long-time critic of the industry’s estimates of shale gas reserves.

McClendon says he agreed to talk to Goodell after he was told that the magazine would publish an article on Chesapeake whether it cooperated or not. Chesapeake has issued a rebuttal to the article (“Although our expectations for honesty and fairness were quite low, the writer failed to reach even that low bar.”), and Goodell has responded to Chesapeake’s rebuttal (“The company entirely dodges the article’s central point: that Chesapeake is a highly-leveraged firm operated by a corporate gambler who engaged in complex scheme to profit off the illusion that America has a virtually unlimited supply of cheap natural gas.”). (Isn’t the internet amazing?)

A study group sponsored by the Massachusetts Institute of Technology has issued a report, The Future of Natural Gas, the fourth in a series of MIT multidisciplinary reports examinging the role of various energy sources and the effects of carbon dioxide emissions restraints.  The full 170-page report can be found here. The report analyzes the relative carbon footprint of natural gas compared to other fuels and the environmental impact of the development of shale gas reserves, among other topics. Here are some excerpts:

Major conclusions of the report:

  • “There are abundant supplies of natural gas in the world, and many
    of these supplies can be developed and produced at relatively low cost.”
  • “The role of natural gas in the world is likely to continue to
    expand under almost all circumstances, as a result of its availability,
    its utility and its comparatively low cost.”
  • Natural gas is “one of the most cost-effective means by which to maintain energy supplies while reducing CO2 emissions.”

Regarding gas’s carbon footprint, the report concludes that “Among
the fossil fuels, it has the lowest carbon intensity, emitting less CO2
per unit of energy generated than other fossil fuels. It burns cleanly
and efficiently, with very few non-carbon emissions. Unlike oil, natural gas generally requires limited processing to prepare it for end use.”

Regarding potential natural gas supply:

  • “The mean projection of [worldwide] remaining recoverable resource
    [of natural gas] in this report is 16,200 Tcf, 150 times current annual
    global natural gas consumption …. Of the mean projection,
    approximately 9,000 Tcf could be developed economically with a natural
    gas price at or below $4/Million British Thermal units (MMBtu) at the
    export point.”
  • “The mean projection of recoverable shale gas resource in this
    report is approximately 640 Tcf, with low and high projections of 420
    Tcf and 870 Tcf, respectively. Of the mean projection, approximately 400 Tcf could be economically developed with a natural gas price at or
    below $6/MMBtu at the wellhead.”

Darell T. Brownlow, Ph.D, has published an article giving his analysis and opinion of the ability of the Carrizo Aquifer to supply water demands caused by fracing of wells in the Eagle Ford play.  The article was published in the newsletter of the Texas Ground Water Association, Fountainhead, and can be found here: Brownlow Article.pdf

Dr. Brownlow, a hydrologist, concludes that there is plenty of water in the Carrizo, in most places, to meet the demands for frac water. His estimates:

  • There are about 6 million acres in the Eagle Ford play, and a possible 20,000 oil and gas wells (one well per 300 acres).
