What Might the 2014 Elections Mean for U.S. Energy and Environmental Policy?

The simple answer is that at this point we don’t know. Lots of different paths are possible, depending on how Republicans interpret their enhanced power in the U.S. Congress, how the President approaches his final two years in office, and how Congressional Democrats react to their minority party role. Nevertheless, I will offer my current thoughts and speculations, subject of course to significant change as we proceed in Congress’ 2014 lame duck session and the start of a new Congress in January with Republicans in charge of both Houses for the first time in eight years.

One major consideration that dominates my thinking is that Republicans, facing inevitable demographic realities in future elections (older white people as a declining percentage of the voting population, more non-white voters/mostly Latino and Asian, and a growing number of young voters generally more progressive than their parents and grandparents), must demonstrate that they can govern effectively if they are to win national elections in the future. Remembering the Gingrich era in the 1990’s, when Republicans took over the Congress, it proved much easier to be in the minority and sling arrows than to govern effectively when finally in power. The modern House of Representatives, under John Boehner as Speaker, has proved to be one of the least effective in American history, but with control of both Houses in Republican hands after January, Boehner and McConnell (the presumed Majority Leaders in the new Congress) have the opportunity to do more than just oppose Obama Administration initiatives. What Boehner and McConnell want to do and are able to do will determine their places in history.

The issues as I see them are as follows: policy for fossil fuel supply – coal, oil, natural gas, fossil fuel exports, Keystone XL pipeline, global warming and climate change, support for clean energy, water issues. Each will be discussed briefly below.

– Fossil fuel supply: with Kentucky’s senior Senator setting the agenda for the Senate it is likely that anti-coal activists will be unsuccessful in accelerating the pace of closure of coal-fired power plants in the near future. These decisions, made on economic grounds by power plant operators, will be self-interested decisions based on the legislative environment they are facing. With Republicans in charge I anticipate every effort will be made to slow down or repeal the EPA’s proposed rules on carbon emissions. While there are Republicans who understand the need to replace coal combustion with natural gas and eventually with renewable energy, the political reality that they may be challenged in reelection primaries by climate change minimalizers or deniers tends to keep them in line with status-quo positions. Coal’s role in power generation in the U.S. is clearly diminishing, faster than most people probably anticipated just a few years ago, but low-cost coal exports to other countries are picking up. As the UK experienced several decades ago, closing coal mines and losing the associated jobs is difficult politics, as this year’s Senate election in Kentucky demonstrated. Keeping one’s job is priority #1 for most if not all people, and the political system needs to keep this firmly in mind. Balancing this against the needs of environmental protection is what we pay our politicians to do.

The issues with oil and natural gas largely relate to fracking and its associated environmental threats, and with their export to other countries. Both are critical issues that can no longer be avoided and require careful policy prescriptions that Republicans are now in a better place to affect. Fracking of oil and natural gas from extensive shale deposits has expanded rapidly in the U.S. in recent years, and the U.S. Is rapidly becoming the world’s #1 oil producer (when shale oil adds to our declining but still large traditional domestic oil production) and a major souce of natural gas supplies. As discussed in two previous posts on this blog web site, I see no way to stop fracking in the U.S. because of the large associated economic returns, and therefore we must regulate it carefully to avoid the real possibility of water supply contamination and minimize accidental releases of methane, a powerful global climate change gas. Republicans can have their cake and eat it too if they support this needed regulation, gaining brownie points for their environmentalism and still allow the fracking industry to proceed on their profitable path. Substituting fracking gas for coal in power generation is in most people’s interest, and while I would prefer to replace coal with wind, solar and other renewable generation sources, we are not in a position to do that yet. Nevertheless, the U.S. public largely understands the need for this inevitable transition and Republicans would be politically wise to take a long-range view on facilitating this transition. We shall see.

A related issue is what to do about U.S. producers who want to export oil and natural gas. Large and remunerative potential markets await in Europe and Asia but since the 1970’s it has been illegal for companies to export crude oil in all but a few circumstances. The goal of the 1970’s legislation was to conserve domestic oil reserves and discourage foreign imports, but in reality, the export ban did not help accomplish either objective.

The Natural Gas Act of 1938, as amended, requires that anyone who wants to import or export natural gas, including liquefied natural gas (LNG), from or to a foreign country must first obtain an authorization from the Department of Energy. This is less of a barrier than the ban on oil exports, but until recently the U.S. was anticipating importing LNG, not exporting it. The fracking revolution has changed all this, and LNG import terminals are now being constructed as export terminals.

An argument against such exports is less fossil fuel and potentially higher energy costs for U.S. consumers. Foreign policy as well as economic considerations come into this discussion as we try to loosen other country’s dependence on Russian and Middle East producers. I anticipate that export controls will be loosened on a bipartisan basis and the U.S. will emerge as a major energy exporter in the decades to come.

Approval of the Keystone XL Pipeline by the President will be a key issue in the upcoming lame duck session of Congress and may carry over to the new Congress in January. My own view, expressed in an earlier blog post, is that stopping construction of the pipeline will not slow Canadian development of its tar sands oil resources and that I’d rather have the oil coming to the U.S. rather than going elsewhere. I also believe that transport of oil by pipeline is safer than transport by rail car, the obvious and unstoppable alternative. With regard to this issue, which many environmentalists have identified as a litmus test for President Obama’s environmental bona fides, I see the pipeline, which has strong Republican support as well as some Democratic support, as a done deal, perhaps as part of a tradeoff with other Democratic priorities such as immigration reform.

The issue of global warming and climate change is a difficult partisan issue but shouldn’t be. The science of understanding global warming is advancing steadily, its risks are clear to most people, and the largely negative impacts of climate change are increasingly being documented. The problem in the U.S. Is the political clout of industries dependent on sales of fossil fuels. In addition, Republican control of the Senate means that chairmanship of the Environment and Public Works Committee will fall to Sen. James Inhofe (R-OK), a climate change denier. This is clearly bad news for environmentalists and others who are concerned about climate change, but also for Republicans and Democrats who will eventually have to deal with this global crisis. Inhofe can slow things down and probably will, at least for the next two years before another Senate election is scheduled. It will be up to members and leaders of both parties to limit the damage that Inhofe can do.

Support for clean energy (efficiency, renewables) should also not be a partisan issue, but unfortunately is. Vested interests in the traditional energy industries still have too much power with a Congress highly dependent on campaign funds. My views on the need to accelerate the transition to a clean energy economy are clearly stated in quite a few of my blog posts, reflecting my view that such a transition is inevitable and clearly in the national interest. Unfortunately, I expect the next few years, under Republican control of Congress, to be a repeat of the years under President George W. Bush (‘Bush 43’) when lip service was paid to clean energy but budget support didn’t follow. As I was taught on my first days in Washington, DC in 1974, budget is policy. I hope President Obama will take a strong stand on these issues, despite Republican electoral gains, since he no longer has to protect vulnerable Democratic candidates.

I bring water into this discussion because water and energy issues are ‘inextricably linked’. Energy production requires water and provision of clean water supplies requires energy. Republicans as well as Democrats must recognize the need to consider these two issues together, and I think they will. This issue needs visibility and increased understanding on the part of politicians and the public, and is a natural for bipartisan cooperation. I hope I am right.

Obviously, I have only touched lightly on the many energy and environmental issues facing the U.S., and encourage others to join me in this discussion. These next few years should be interesting indeed!

Shale Gas and Hydraulic Fracturing – Framing the Water Issue

A detailed report on fracking (‘Shale Gas and Hydraulic Fracturing – Framing the Water Issue’), co-authored with two Swedish colleagues Gustaf Olsson and Andreas Lindstrom, was released today by SIWI, the Swedish International Water Institute. The report’s Executive Summary is included below; the full report can be found at http://www.siwi.org.

SIWI Report no. 24/Executive Summary
“Shale Gas and Hydraulic Fracturing – Framing the Water Issue” by Andreas Lindström, SIWI, Dr. Allan Hoffman, US Department of Energy/retired, and Prof. Gustaf Olsson, Lund University.

The emergence of shale gas and shale oil has quickly changed the landscape of opportunities for energy provision and security in different regions of the world. Difficulties in assessing the actual quantity of existing global shale hydrocarbon reserves produce opposing views on whether the world is on the verge of a “shale gas revolution” and, if it is, how long it could last. Some argue that shale gas may constitute a backbone of energy supply for specific countries for decades to come, while others say the peak may have passed already.

Despite this, some nations – such as the USA – have already started an ambitious exploitation of this comparatively cheap energy resource, providing new and favourable conditions for domestic energy supplies and costs, and creating new jobs in the booming shale industry. For various reasons other countries have not taken the plunge, despite assessed quantities of shale resources. These reasons include fear of possible severe environmental impacts. These are often associated with shale gas extraction accomplished through the technology known as hydraulic fracturing, or “fracking”; evidence of the impacts is emerging in places where intense, unregulated fracking takes place.

Many of these impacts make themselves felt in water resources. Fracking is a water-intensive activity, and as the reserves are often found in dry areas extraction poses additional challenges in what are often already water-stressed environments. The vast water quantities needed over the life span of a shale gas well, where water is used to fracture rock under high pressure, pile further stress on local fresh water sources which are already needed for many different purposes. At times when water supplies are running short in a specific area it has to be transported to the fracking site from afar.

Water quality is also under threat from fracking as well as the quantity available. Many chemicals used in the fracking fluid (the composition of which is often protected for commercial confidentiality reasons) have increasingly been found to be harmful both to the environment and to human health, yet poor regulations and legislation governing fracking often allow accidents which contaminate surrounding water sources. There is a need for greater responsibility, through developing codes of conduct and regulatory systems governing fracking so as to protect water resources and the environment. It should be adopted by all nations currently exploiting or liable to exploit shale resources as part of their energy supply.

Looking Ahead 30-40 Years – A Risky Business

History has always been my favorite subject, starting in high school, and still constitutes a major part of my personal reading. Needless to say I have a strong interest in other topics as well, as attested to by my long career in science and engineering and education/mentoring activities with young people. What often fascinates me is looking back at how things have changed in the past, often in unexpected ways, and how people looking back in the decades ahead will put their perspectives on what we are doing today. This blog post is my attempt to flesh out these thoughts, while acknowledging the difficulty of looking into the future. If I look far enough into that future I will not be around to suffer the slings and arrows of projecting incorrectly, or collecting the kudos for projecting accurately. Nevertheless, it feels like a stimulating and challenging activity to undertake, and so here goes.

image

Let me start by going back seven decades to the 1940s when I was a young kid growing up in the Bronx and just beginning to form my likes and dislikes and develop opinions. My love for science fiction developed at that time and was probably a dead give-away of my future career interests. An important shaping event was the dropping of the first atomic bomb on Japan on August 6, 1945, an event that I still clearly remember learning about on the radio while sitting in the back seat of my parents’ car. Without a deep or much of any understanding at that time, I somehow sensed that the world had changed in that August moment. I still feel that way after many subsequent years of reading and studying.

The following decades saw several other unexpected and defining events: the addition of fusion weapons (hydrogen bombs) to our nuclear arsenals, commercial applications of controlled nuclear fission (nuclear submarines and nuclear-powered surface ships, and the first commercial nuclear power plant which was actually a land-based nuclear submarine power plant), development and emergence of the transistor as a replacement for vacuum tubes (first using germanium and then silicon), the development of the first solar cell at Bell Labs, the development and application of laser technology, the emergence of the information technology industry based on the heretofore abstract concepts of Boolean algebra (0s and 1s), and the increasing attention to a wide range of clean energy technologies that had previously been considered impractical for wide scale application – wind, solar, geothermal, ocean energy, fuel cells, advanced battery technologies, and a broad range of alternative liquid and gaseous fuels. Each in its own way has already changed and will further change the world in future decades, as will other technologies that we now only speculate about or cannot imagine. This is the lesson of history – it is difficult for most of us to look ahead and successfully imagine the future, and one of my earlier blog posts (‘Anticipating the Future: It Can Be Difficult’) discusses this topic. In the following paragraphs I speculate about the future with humility but also great anticipation. My only regret is that I will not live long enough to see most of this future unfold.

I will divide this discussion into two parts on which I have focused some attention and feel that I have some knowledge – medicine/health care, and energy. That leaves all too many aspects of the future that I don’t feel qualified to comment upon – e.g., what more will we learn about Amelia Earhart’s disappearance, Cuba’s possible participation in John Kennedy’s assassination, and the future of the tumultuous Middle East and the countries of the former Soviet Union. My primary focus in this post will be on the latter of the two parts, energy.

To help you understand my interest in medicine and health care I confess that at one point in my career, before committing to pursuing a PhD in physics, I gave serious consideration to attending medical school. During this period in the early 1960s I was a research scientist at Texas Instruments (TI) and was excited about the possibilities of miniature electronics which TI was pioneering in. I even suggested to my TI bosses that we undertake the application of transistors and sensors to artificial vision, but it was much too early for the company to make such a commitment. Today, 50 years later, that vision is being realized.

I also see great promise in the application of miniature electronics to continuous in-vivo diagnosis of human health via capsules that float throughout a human’s blood network, monitor various chemical components, and broadcast the results to external receivers. This will depend on low-powered miniature sensors and analysis/broadcast capability powered by long-lasting miniature batteries or an electrical system powered by the human body itself. Early versions are now being developed and I see no long-term barriers to developing such a system.

A third area in which I see great promise is the non-invasive monitoring of brain activity. This is a research area that I see opening up in the 21st century as we are beginning to have the sensitive tools necessary to explore the brain in detail. Given that the brain is responsible for so many aspects of our mental and physical health I expect great strides in the coming decades in using brain monitoring to address these issues.

The energy area is where I have devoted the bulk of my professional career and where my credibility may be highest – at least I’d like to think so. Previous blog posts address my thoughts on a wide range of current energy, water-energy, and related policy issues. Recognizing that changes in our energy systems come slowly over decades and sometimes unexpectedly, as history tells us, I will share my current thoughts on where I anticipate we will be in 30-40 years.

Let me start with renewable energy – i.e., solar, wind, hydropower, geothermal, biomass, and ocean energy. I have commented on each of these previously, but not from a 30-40 year perspective. Renewables are not new but, except for hydropower, their entering or beginning to enter the energy mainstream is a relatively recent phenomenon. Solar in the form of photovoltaics (PV) is a truly transformative technology and today is the fastest growing energy source in the world, even more so than wind. This is due to significant cost reductions for solar panels in recent years, PV’s suitability for distributed generation, its ease and quickness of installation, and its easy scalability. As soon as PV balance-of-system costs (labor, support structures, permitting, wiring) come down from current levels and approach PV cell costs of about $0.5-0.7 per peak watt I expect this technology to be widespread on all continents and in all developed and developing countries. Germany, not a very sunny country but the country with the most PV installed to date, has even had occasional summer days when half its electricity was supplied by solar. In combination with energy storage to address its variability, I see PV powering a major revolution in the electric utility sector as utilities recognize that their current business models are becoming outdated. This is already happening in Germany where electric utilities are now moving rapidly into the solar business. In terms of the future, I would not be surprised if solar PV is built into all new residential and commercial buildings within a few decades, backed up by battery or flywheel storage (or even hydrogen for use in fuel cells as the ultimate storage medium). Most buildings will still be connected to the grid as a backup, but a significant fraction of domestic electricity (30-40%) could be solar-derived by 2050. The viability of this projection is supported by the NREL June 2012 study entitled ‘Renewable Electricity Futures Study’.

Hydropower already contributes about 10% of U.S. electricity and I anticipate will grow somewhat in future decades as more low-head hydro sites are developed.

For many years onshore wind was the fastest growing renewable electricity source until overtaken recently by PV. It is still growing rapidly and will be enhanced by offshore wind which currently is growing slowly. However, I expect offshore wind to grow rapidly as we approach mid-century as costs are reduced for two primary reasons: it taps into an incredibly large energy resource off the coasts of many countries, and it is in close proximity to coastal cities where much of the world’s population is increasingly concentrated. In my opinion, wind, together with solar and hydro, will contribute 50-60% of U.S. electricity in 2050.

Other renewable electric technologies will contribute as well, but in smaller amounts. Hot dry rock geothermal wells (now called enhanced geothermal systems) will compete with and perhaps come to dominate traditional geothermal generation, but this will take time. Wave and tidal energy will be developed and become more cost effective in specific geographical locations, with the potential to contribute more in the latter part of the century. This is especially true of wave energy which taps into a large and nearly continuous energy source.

Biomass in the form of wood is an old renewable energy source, but in modern times biomass gasification and conversion to alternative liquid fuels is opening up new vistas for widescale use of biomass as costs come down. By mid-century I expect electrification and biomass-based fuels to replace our current heavy dependence on petroleum-based fuels for transportation. This trend is already underway and may be nearly complete in the U.S. by 2050. Biomass-based chemical feedstocks will also be widely used, signifying the beginning of the end of the petroleum era.

I expect that other fossil fuels, coal and natural gas, will still be used widely in the next few decades, given large global resources. Natural gas, as a cleaner burning fossil fuel, and with the availability of large amounts via fracking, will gradually replace coal in power plants and could represent 30-40% of U.S. power generation by mid-century with coal generation disappearing.

To this point I have not discussed nuclear power, which today provides close to 20% of U.S. electricity. While I believe that safe nuclear power plants can be built today –i.e., no meltdowns – cost, permanent waste storage, and weapons proliferation concerns are all slowing nuclear’s progress in the U.S. Given the availability of relatively low-cost natural gas for at least several decades (I believe fracking will be with us for a while), the anticipated rapid growth of renewable electricity, and the risks of nuclear power, I see limited enthusiasm for its growth in the decades ahead. In fact I would not be surprised to see nuclear power supplying only about 10% of U.S. electricity by 2050, and less in the future.

To summarize, my picture today of an increased amount of U.S. electricity generation in 2050 is as follows:

Generating Technology : Percent of U.S. Generation in 2050
nuclear: 5-10
coal: 0-5
Oil: 0
natural gas: 30-40
solar + wind + hydro: 50-60
other renewables: 5-10

I am sure that some readers of this post will take strong issue with my projections and have very different thoughts about the future. I welcome their thoughts and invite them to join me in looking ahead. As the title of this post acknowledges, looking ahead is risky business, but it is something I’ve wanted to do for a while. This seems as good a time as any to do so.

Peak Oil: A Valid or Invalid Concept?

One topic that has come up consistently in my 40+ years of reading and thinking about energy is the notion that the world is running out of fossil fuels. The reality, as best I can tell, is that this is not true on any near-term timescale. Fossil fuels are finite and we are using them faster than nature can replace them, but much remains to be found and utilized if people wish. The concerns stimulated by H. King Hubbert in 1956, when he proposed his theory on oil well production and depletion and published the ‘Hubbert Curve’ (see below) are valid for some assumptions but ignore other realities that make his conclusions, and those of others who have accepted his theory, invalid for long-term planning. I will explain why I believe this in the discussion that follows, recognizing that part of the discussion turns on a definition of what is meant by Peak Oil.

image
A 1956 world oil production distribution, showing historical data and future production, proposed by M. King Hubbert; it has a peak of 12.5 billion barrels per year about the year 2000

Hubbert’s Peak Theory is based on the obvious fact that the utilization of a finite resource must go through an initial start-up, reach a peak level of production, and eventually tail off as the resource is depleted. This is common sense, applicable to all non-renewable resources, and not disputable. What is disputable is the shape of the production/depletion curve and the assumptions that went into identifying the resource to be utilized and eventually depleted. Much of the public discussion that has ensued about Peak Oil, the application of Hubbert’s theory to oil (petroleum) extraction, since publication of Hubbert’s 1956 paper has revolved about these two facets of his theory.

It is important to clarify up front that Peak Oil is the point in time when oil extraction reaches its maximum rate and is not synonymous with oil depletion. Following a peak in extraction rate about half of the resource is still available for extraction, and production rate decreases steadily thereafter. Much discussion has focused on the shape of the declining curve after Peak Oil is reached – plateau? sharp decline? slow decline? – and the implications for the U.S. and world economies that are so dependent on oil supplies.

Hubbert’s theory received great visibility when he correctly predicted, in his 1956 paper, that U.S. domestic oil production would peak between 1965 and 1971. He used the terms ‘peak production rate’ and ‘peak in the rate of discoveries’; the term Peak Oil was introduced in 2002 by Colin Campbell and Kjelll Aleklett when they formed ASPO, the Association for the study of Peak Oil & Gas.

Where the application of Hubbert’s theory has failed (I don’t blame him) is in the boundary conditions (assumptions) on which his theory is based. He did not anticipate, nor did others, the rapid emergence of unconventional oil and the substitutions for oil (alternative fuels, electrification of transportation) that have been or are being developed. He did mention these possibilities and did his best with the information available at the time; I cannot say that about modern Peak Oil theorists who still put out stories intended to scare.

What has changed is that oil production no longer depends only on ‘conventional’ oil supplies but increasingly on ‘unconventional’ resources that are an increasing part of total oil supply. A few definitions, courtesy of Wikipedia, will help:

“Conventional oil is oil that is generally easy to recover, in contrast to oil sands, oil shale, heavy crude oil, deep-water oil, polar oil and gas condensate. Conventional oil reserves are extracted using their inherent pressure, pumps, flooding or injection of water or gas. Approximately 95% of all oil production comes from conventional oil reserves.

Unconventional oil is oil that is technically more difficult to extract and more expensive to recover. The term unconventional refers not only to the geological formation and characteristics of the deposits but also to the technical realisation of ecologically acceptable and economical usage.”

Given these definitions, we can probably all agree that the age of cheap oil is over, as reflected in the following graph of historical oil prices:

As reported by former BP geologist Dr. Richard Miller in a speech at University College of London in 2013: “..official data from the International Energy Agency, the US Energy Information Administration, the International Monetary Fund, and other sources, showed that conventional oil had most likely peaked around 2008.” He further pointed out that “peaking is the result of declining production rates, not declining reserves”, that many oil producing countries are already post-peak, and that conventional oil production has been flat since about the middle of the past decade. There has been growth in liquid supply since then, largely due to natural gas liquids and oil derived from oil sands. Reserves have also been growing due to new discoveries, improved oil field extraction technology, and increasing reliance on unconventional resources.

The debate about Peak Oil has been underway for quite a few decades, many words have been spoken and much ink has been used to illuminate and document that debate, and Peak Oil still has its adherents. One of my purposes in exploring this subject for my blog was to review the latest literature and form an updated opinion. I have – Peak Oil is not real if you take into account the full liquid fuels situation. In fact, in the course of my research I have come across several opinions that I fully agree with and share them with you as my summation of this post.

(Wikipedia)”In 2009, Dr. Christoph Rühl, chief economist of BP, argued against the peak oil hypothesis:

Physical peak oil, which I have no reason to accept as a valid statement either on theoretical, scientific or ideological grounds, would be insensitive to prices. (…) In fact the whole hypothesis of peak oil – which is that there is a certain amount of oil in the ground, consumed at a certain rate, and then it’s finished – does not react to anything…. Therefore there will never be a moment when the world runs out of oil because there will always be a price at which the last drop of oil can clear the market. And you can turn anything into oil into if you are willing to pay the financial and environmental price… Global Warming is likely to be more of a natural limit than all these peak oil theories combined. (…) Peak oil has been predicted for 150 years. It has never happened, and it will stay this way.

According to Rühl, the main limitations for oil availability are “above ground” and are to be found in the availability of staff, expertise, technology, investment security, money and last but not least in global warming. The oil question is about price and not the basic availability. Rühl’s views are shared by Daniel Yergin of CERA, who added that the recent high price phase might add to a future demise of the oil industry, not of complete exhaustion of resources or an apocalyptic shock but the timely and smooth setup of alternatives.”

One other opinion I agree with, by George Monbiot, writing in the guardian on 2 July 2012 (‘We were wrong on peak oil. There’s enough to fry us all’): “Some of us made vague predictions, others were more specific. In all cases we were wrong. In 1975 MK Hubbert, a geoscientist working for Shell who had correctly predicted the decline in US oil production, suggested that global supplies could peak in 1995. In 1997 the petroleum geologist Colin Campbell estimated that it would happen before 2010. In 2003 the geophysicist Kenneth Deffeyes said he was “99% confident” that peak oil would occur in 2004. In 2004, the Texas tycoon T Boone Pickens predicted that “never again will we pump more than 82m barrels” per day of liquid fuels. (Average daily supply in May 2012 was 91m.) In 2005 the investment banker Matthew Simmons maintained that “Saudi Arabia … cannot materially grow its oil production”. (Since then its output has risen from 9m barrels a day to 10m, and it has another 1.5m in spare capacity.)

Peak oil hasn’t happened, and it’s unlikely to happen for a very long time.”

Enough said!
