New Book: ‘Water, Energy, and Environment – A Primer’

After a long hiatus from blogging while I worked on a new book, I am pleased to announce that the book ‘Water, Energy, and Environment – A Primer’ will be published by International Water Association Publishing (IWAP) on February 18th (2019). It will be available in both printed and digital form, and the digital version will be downloadable for free as an Open Access (OA) document.

To access the free digital version go to IWAP’s OA website on Twitter: https://twitter.com/IWAP_OA.

Attached below is front material from the book, its preface and table of contents. Designed to serve as a basic and easily read introduction to the linked topics of water, energy, and environment, it is just under 200 pages in length, a convenient size to throw into a folder, a briefcase, or a backpack. Its availability as an OA document means that people all over the world with access to the internet will have access to the book and its 10 chapters.

With the completion of the book I plan to return to a regular schedule of blogging.

Preface
This book springs from my strong conviction that clean water and clean energy are the critical elements of long-term global sustainable development. I also believe that we are experiencing the beginning of an energy revolution in these early years of the 21st century. Providing clean water requires energy, and providing clean energy is essential to reducing the environmental impacts of energy production and use. Thus, I see a nexus – a connection, a causal link – among water, energy, and environment. In recent years we have adopted the terminology of the water-energy nexus for the intimate relationship between water and energy, and similarly we can apply the term nexus to the close connections among water, energy, and environment. Thisuse of the term nexus can be, and has been, extended to include the related issues of food production and health. Dealing with, and writing about, a two-element nexus is difficult enough. In this book, I will limit my analysis and discussion to the three-element water -energy-environment nexus and leave the discussion of other possible nexus elements to those more qualified to comment.

This book also springs from my observation that while there are many existing books of a more-or-less technical nature on the three elements of this nexus, a book addressing each of them and their interdependencies in a college-level primer for a broad global and multidisciplinary audience would be valuable. Consideration of these and related issues, and options for addressing them, will be priorities for all levels of government. They will also be priorities for many levels of the
private sector in the decades ahead, both in developing and developed nations. A handbook-style primer that provides an easily read and informative introduction to, and overview of, these issues will contribute broadly to public education. It will assist governments and firms in carrying out their responsibilities to provide needed services and goods in a sustainable manner, and help to encourage young people to enter these fields. It will serve as an excellent mechanism for exposure of experts in other fields to the issues associated with the water-energy-environment nexus. Further, in addition to the audiences mentioned above, target audiences include economists and others in the finance communities who will analyze and provide the needed investment funds, and those in the development community responsible for planning and delivering services to underserved populations.
The book is organized as follows: the first chapter will be devoted to the concept of nexus and how the three elements, water, energy, and environment, are inextricably linked. This recognition leads to the conclusion that if society is to optimize their contributions to human and planetary welfare they must be addressed jointly. No longer must policy for each of these elements be considered in its own silo. Chapters 2 and 3 will be devoted to spelling out global contexts for water and energy issues, respectively. Chapter 4, on related environmental issues, will address the issues of water contamination, oil spills, fracking, radioactive waste storage, and global warming/
climate change. Chapter 5 will be a discussion of energy efficiency – i.e., the wise use of energy – and its role in limiting energy demand and its associated benefits. Chapter 6 will focus on the basics of fossil fuels – coal, oil, natural gas – which today dominate global energy demand. Chapter 7 will discuss nuclear-fission-powered electricity production, which today accounts for 10% of global electricity. It will also discuss the prospects for controlled nuclear fusion. Chapter 8 will discuss the broad range of renewable energy technologies – wind, solar,hydropower, biomass, geothermal, ocean energy – which are the basis of the now rapidly emerging energy revolution. Chapter 9 will discuss the closely related issue of energy storage. Finally, Chapter 10 will address
policy issues associated with water, energy, and environment, discuss policy history and options, and provide recommendations.

A New Book On Solar Energy In Africa and the Middle East

I have not posted on this blog web site for a while because my writing efforts were diverted to helping create a new book entitled ‘The Sun Is Rising In Africa and the Middle East: On the Road to a Solar Energy Future”. The book went to the printer earlier this week and should be available in printed form shortly. A digital version is also in the works. The book has three authors and three additional contributors, each bringing a rich perspective and set of experiences to the discussion. To whet your appetitites I include below the first few pages of the manuscript, including the Table of Contents. More information coming when the book is actually available for sale.

Recognizing the Water-Energy Nexus

The following article was published recently on Wiley’s online journal Global Challenges. It serves as the prologue to a special issue on water and energy issues that was edited by Gustaf Olsson and Perer Lund. It discusses, in a personal way, my professional involvement with these strongly related issues.

Water–Energy Nexus
Global Challenges Special Issue on Water and Energy

Prologue: Recognizing the Water-Energy Nexus: A Personal Recollection
By Allan Hoffman

My first professional contact with water issues came in August 1999 when I was invited to represent the U.S. Department of Energy (DOE), my employer, at a meeting in Amman, Jordan. The meeting was to plan a major Middle East water conference for later that year in Amman that would involve King Hussein of Jordan, President of the Palestinian Authority (PA) Yasser Arafat, and Prime Minister Ehud Barak of Israel. The motivation for the conference was clear—U.S. President Bill Clinton, assisted by King Hussein, was actively engaged in Middle East peace talks with the Israelis and the Palestinians and water was a principal issue in these negotiations. The planning meeting, to take place a few weeks later in mid-September, was to set the stage for a meaningful dialogue on water that would advance the peace process.

I remember well the moment I received the invitation because of my immediate reaction to Gene DeLaTorre, who delivered the invitation on behalf of DOE’s Assistant Secretary for Policy: “Why me? I don’t know a damn thing about water except what I read in the papers.” Gene, whom I had not known previously but subsequently became a good friend, gave me the three reasons I was targeted: I was a senior DOE official, an expert on renewable energy, which was recognized as part of the solution, and had considerable experience through my work on renewable energy dealing with senior officials in other governments. Not having a good reason to say no, and interested in doing what I could to help the peace process, I said yes and put myself on a fast learning curve.

That learning curve included lots of reading on global water fundamentals, the Middle East water situation, desalination, and meetings with former government and current think tank officials with experience in the Middle East. Less than a month after receiving and accepting the invitation I was on my way to Frankfurt, Germany to meet up with two scientists from Lawrence Livermore National Laboratory (LLNL) who would be joining me for the final leg to Amman. Unfortunately, one of the LLNL scientists missed the connecting flight to Frankfurt and had to take a later flight with a middle of the night stop in Syria. He also arrived in Amman without his luggage and attended our first meeting the next morning in his jeans and sneakers.

The majority of the participants in the planning meeting were water experts from Jordan, Israel and the Palestinian Authority, people who had been cooperating for many years and knew one another well. The PA delegation was led by Nabil al Sharif, the PA Water Minister and a civil engineering classmate of Arafat. The U.S. delegation was small, consisting of me and the two LLNL scientists, a Middle East water expert from the U.S. Department of State, and a former U.S. Congressman from Utah who was focused on U.S.-Middle East dialogue and was a moving force behind the planning meeting. In total, about fifty people participated in the two-day meeting.

My role was to bring an energy perspective to the meeting, in addition to the hydrologic expertise of the LLNL staffers and the political experience of the State Department representative. The meeting went well, reflecting the shared interests and perspectives of the water experts who had clearly worked together in the past, and I learned a great deal. In fact, my growing interest in water issues peaked when Nabil stood up at one point in the meeting to state that there would be no peace in the Middle East until the water issue was addressed.

Upon returning to the U.S. after the meeting, having concluded that water issues were much more important than I had realized, I resolved to learn as much as I could. Even though George W. Bush was elected U.S. President in November and Republicans took over the Executive Branch on January 20, 2001 (note: I had served as a political appointee in the Democratic Carter Administration in the 1970s), my senior status at DOE and control over most of my calendar allowed me the time to pursue my water education. Very quickly I realized that many of the things I had been saying in my public presentations on energy applied to water as well: there is no shortage of energy (water) in the world; what is in short supply is inexpensive energy (clean water) that people can afford to buy; energy (water) security depends on the wise use of the resource, whatever its source. This was my first realization of the close connection between water and energy, an understanding that I presumed other people shared. What surprised me, as I began to talk about this with people in both the water and energy communities, is that energy people rarely thought about water except as it was needed to cool thermal power plant exhausts and run through hydropower plants, and water people rarely thought about the energy needed to provide water services.

As I delved further into the nexus I came to understand the following: Central to addressing issues of water security—defined as the ability to access sufficient quantities of clean water to maintain adequate standards of food and goods production, sanitation and health—is having the energy to extract water from underground aquifers, push water through pipes and canals, manage and treat impaired water for reuse, and desalinate brackish and sea water to provide new fresh water supplies. Many aspects of energy production depend on the availability of water including hydropower, cooling of thermal power plants, fossil fuel production and processing, biofuels, carbon capture and sequestration, and hydrogen production. The inextricable linkage between energy and water is clear, but hasn’t always been recognized.

Other, indirect, linkages exist as well. Energy production and use can lead to contamination of underground and surface water supplies. If competing water uses limit use of waterways for transport of goods, rail and truck will require more energy to move those goods. Another critical linkage is that energy production and use are major contributors to greenhouse gas emissions, which have the potential to disrupt the hydrological cycle and impact global water resources long before other impacts are felt. By altering the timing of winter snows, snowmelt, and spring rains, climate change could overload reservoirs early in the season, forcing releases of water and leaving areas like California and the Himalayas high and dry in late summer. Coastal areas and island nations also face a serious threat from rising ocean water levels that destroy property and flood low-lying areas, causing salt-water intrusion of fresh-water supplies and putting the drinking water of millions at risk.

In June 2000 I felt confident enough of my growing knowledge to give a talk on water–energy issues to the Organization of American States: “Water, Energy and Sustainable Development”. This was followed by presentations to the World Renewable Energy Council in July and to an electric utility industry conference in March 2001. I also began to write on the subject and remember asking one of my colleagues, who was an accomplished writer, if it would be acceptable to use the word ‘nexus’ to describe the relationship—i.e., would it be easily understood? He said yes and so the phrase water–energy nexus was born.

During those early days at the start of the new century I was trying to generate some interest in DOE to explore this interesting connection, which I believed had relevance for several of DOE’s programs, but with little success. When the issue reached my new Assistant Secretary he dismissed the effort as ‘mission creep’ that would divert funding from other programs. Thus, to the best of my knowledge, my efforts constituted DOE’s only focused attention to the water–energy nexus at that time. Following several public presentations in 2003 and early 2004 the first real breakthrough came in August 2004 when I was invited to write a paper on water and energy security for the Institute for the Analysis of Global Security, where I served as a technical advisor. This request came in on a Wednesday; the article was published the following week and quickly led to more speaking opportunities. One of the more interesting was a presentation in September to FERC, the U.S. Federal Energy Regulatory Commission, on the topic “Water and Energy Security”. Another opportunity was a plenary address to the 2005 Solar World Congress in August 2005 entitled “Water Security: A Growing Crisis”, which was also published as the lead article in the July/August 2005 issue of Solar Today magazine. There were many other speaking opportunities in the following years, including presentations to the National Science Foundation, Lockheed-Martin Corporation, the U.S. State Department, the National Association of State Universities and Land Grant Colleges, the Brookings Institution, the Environmental Protection Agency, the IEA Working Party on Renewable Energy, the U.S. National Academies of Sciences, the International Water Association, and others.

Another important step in recognizing the water–energy nexus was the realization, at a regular meeting of DOE and U.S. National Laboratory officials to discuss DOE’s research needs, that many of the Labs had an interest in the water–energy connection but were pursuing it quietly on their own using small amounts of discretionary funds. I did a brief overview of the topic at the meeting and an entire afternoon ended up being devoted to Laboratory discussions of their activities. What came out of that meeting was the organization of a coordinated National Laboratory effort on water–energy issues to be led by Sandia National Laboratory (SNL) and Lawrence Berkeley National Laboratory (LBNL). Both Laboratories had committed resources to exploring the linkage between water and energy, and LBNL, involved in State of California water efforts, even had a dedicated water–energy technology team called WET. Other important players were Oak Ridge National Laboratory, which years earlier had led studies on desalination, and the National Energy Technology Laboratory (NETL), supported by DOE’s Fossil Energy Program. The resultant coordinated National Laboratory team soon provided briefings on the nexus for senior DOE managers.

To illustrate how quietly these Lab efforts had been underway, I had close contacts with LBNL through my clean energy efforts, and was totally surprised to learn of WET. When I mentioned this to a close friend at LBNL he invited me to spend a day at the Berkeley Lab to get briefed on their water activities and to talk about mine. It was an illuminating day on both parts.

Another important step was a meeting in 2008 with Professor Gustaf Olsson of Lund University in Sweden. He had read some of my papers, was on a visit to the U.S., and, expressing interest in learning more, asked to meet. We had a lengthy conversation in which I offered to share more of my work and a collaboration was born that lasts till this day. The rest is history—Gustaf undertook to master this field and in 2012 published his important book entitled “Water and Energy: Threats and Opportunities”, which is now in its second edition.

While there was no specific support for U.S. water–energy nexus studies during the Bush–Cheney Administration (2001-2008), there was a growing understanding that energy generation was the major contributor to the growing threat of global warming and climate change that would have major implications for precipitation patterns, water supply, and frequency of extreme weather events. As a result the phrase water–energy nexus was beginning to be heard more often and conferences began to be organized around that theme. Fracking of oil and gas shales, to increase fossil fuel supplies, also emerged as a contentious issue, given its large water demands and its potential for contaminating water supplies. To address that topic I organized a session on fracking for the Ground Water Protection Council Annual Forum in September 2010.

Throughout this period I continued to speak and write, and was encouraged by the election of Barack Obama as President of the U.S. in November 2008. Unlike the Bush Administration, which effectively denied the reality of global warming, President Obama talked openly about the need for global cooperation in addressing climate change. This was reflected in an Executive Order issued shortly after his inauguration that called on the federal departments and agencies to work together in identifying the potential impacts of global warming on U.S. government programs. This was an exciting time in which staff from all over the government worked together on multi-agency teams to carry out the mandated study. As the principal DOE official with a background in water–energy issues I was assigned to three of these teams, and on one was joined by a staff member from DOE’s policy office. Within a few months a comprehensive study was delivered to President Obama’s office.

With a Democratic Administration in place, I assumed water–energy issues would get increased attention and even some financial support. This proved to be naïve on my part as the new Democratic appointees to head the Office of Energy Efficiency and Renewable Energy (EERE) transferred me from my position in the EERE Policy and Budget Office to the Wind Power Program, where I was told that if I joined them I could no longer pursue my water–energy nexus activities. Rather than retire at that time, which I certainly could have done, I talked with people in the Wind Program and decided to serve as a graybeard in the newly established Office of Offshore Wind and help the program get started. I was and am enthusiastic about offshore wind as the most important emerging renewable energy technology.

This phase of my career ended with my retirement from DOE in 2012 and my decision to share my perspectives on renewable energy and water–energy issues via my writing, of which this invited article is one part. DOE has also taken steps to formally recognize the nexus as part of its program activities via a study released in 2015. The issue is finally getting more of the attention it deserves.

Jobs? Investing in renewables beats fossil fuels
May 19, 2017 by Allan Hoffman

For policymakers who are interested in job creation, investing in renewable energy is considerably more effective than investing in fossil fuels, writes Allan Hoffman, author of the blog Thoughts of a Lapsed Physicist and formerly with the U.S. Department of Energy. Solar and wind are powerful engines of job creation and economic growth.

Job creation is always a safe issue for politicians to address and it played a crucial role in our recent presidential election. Donald Trump achieved his unexpected upset victory over Hillary Clinton by appealing to disaffected workers in normally Democrat-leaning states such as Pennsylvania and Wisconsin. A primary focus of the Trump campaign was jobs in the manufacturing and coal-mining industries, where many workers had been laid off in recent years. Some people have blamed these job losses on Obama Administration policies, including support for solar and wind energy. What are the facts?

The fact that renewable energy, mostly in the form of solar and wind energy, is entering the energy mainstream, both in the U.S. and in other countries, is a reality. This is often attributed to their reduced costs and role in reducing carbon emissions. What is often overlooked or given minimal attention is that investment in the manufacture and deployment of these clean energy technologies creates many ‘green jobs’. What data supports this statement?

Already the largest source of renewable energy jobs in the U.S., solar energy will be a major factor in shaping our future energy system and creating new jobs

Data for the U.S. was available from the Green Jobs Initiative of the Bureau of Labor Statistics in annual reports for fiscal years 2009, 2010, and 2011. Unfortunately, budget sequestration brought an end to this program in 2013. Today other organizations are filling the gap, e.g. The Solar Foundation’s annual ‘National Solar Jobs Census’, monthly reports from the U.S. Energy Information Administration (EIA), and occasional reports from other non-governmental organizations.

Largest employer

On a global basis the International Energy Agency (IEA) has become a source of jobs information, as has the International Renewable Energy Agency (IRENA) through its Renewable Energy and Jobs Annual Reviews. Two highlights of IRENA’s 2016 Review were that (a) global direct and indirect employment in the renewable energy industry had reached 8.1 million in 2015, a 5% increase over 2014, and (b) solar photovoltaics (PV) was the largest renewable energy employer at 2.8 million jobs, an 11% increase over 2014.

Solar Foundation data indicated that in 2016 the U.S. solar industry (8,600 companies) employed 260,00 workers. This was an increase of more than 20% for the fourth straight year and more than 178% since 2010. This outpaced the overall 2016 national jobs growth rate of 1.5%. California led U.S. states in solar employment with 100,050 jobs.

How do these numbers compare with numbers in the fossil fuel industries? In 2015 workers employed directly in oil and natural gas extraction numbered about 187,000, a decrease of 14,000 from 2014. Indirect related jobs number about 2 million, of which about 40% are at gas stations. Another fossil fuel industry that received considerable attention during the 2016 election was coal mining. It accounted for 68,000 jobs in 2015, continuing its decrease of recent years.

A different story

Looking ahead, what can we expect? As oil and natural gas prices increase from their recent lows, and fracking is therefore reinvigorated, the number of related extraction jobs should stay approximately level. This should continue as long as no cost penalty is imposed on carbon emissions, and Trump Administration support for maintaining and expanding fossil fuel extraction is strong.

Coal is a different story. Long the basis of more than half of U.S. electricity generation, coal’s share of that market is now down to about a third and heading lower. When combusted it is the dirtiest of the fossil fuels, and automation of the coal digging process and competition from fracked and low cost natural gas has signaled the beginning of the end of the coal era and related jobs in the U.S. In addition, utilities are not adding new coal powered systems because their capital and operating costs are higher than for new natural gas, wind and solar power plants (data provided by EIA).

Solar and wind are no longer niche businesses

What are the prospects for renewable energy and related jobs in the U.S. in the future? As reported by the American Wind Energy Association (AWEA), at the start of 2016 jobs in the U.S. wind industry totaled 88,000, an increase of 20% over 2014. This was made possible by the installation of nearly 9,000 megawatts of new electrical generating capacity across 20 states, an increase of 77% over 2014. Wind accounted for 41% of all newly installed U.S. electrical capacity in 2015, ahead of solar (28.5%) and natural gas (28.1%). This growth will continue both onshore, where essentially all U.S. wind turbines have been installed to date, and offshore as this large resource begins to be tapped.

Impressive prospects

Two recent reports have documented the equally impressive prospects for solar energy’s growth. IRENA’s ‘Letting In the Light: How Solar Photovoltaics Will Revolutionize the Electricity System’ states that “The age of solar energy has arrived. It came faster than anyone predicted and is ushering in a shift in energy ownership.”

Bloomberg New Energy Finance reported in a June 2016 report that “..solar and wind technologies will be the cheapest way to produce electricity in most parts of the world in the 2030s..” Already the largest source of renewable energy jobs in the U.S., solar energy will be a major factor in shaping our future energy system and creating new jobs. A recently published book Sun Towards High Noon: Solar Power Transforming Our Energy Future (Pan Stanford Publishing; Peter Varadi editor and contributor) discusses the jobs issue in detail along with other issues, including solar financing, markets, and quality control.

We must not be left behind as this energy transition unfolds in the next several decades

What conclusions can be drawn? If a primary national goal is to create jobs in the energy sector, investing in renewable energy is considerably more effective than investing in fossil fuels. Solar and wind are no longer niche businesses, their widespread use addresses global warming and climate change, and their manufacture and deployment are powerful engines of economic growth and job creation.

The U.S. Congress must recognize this and put policies in place that accelerate their growth. Other countries recognize this potential and are moving rapidly onto this path, some even faster than the U.S. We must not be left behind as this energy transition unfolds in the next several decades, but we must also not forget the people who will be displaced from their jobs in traditional energy industries.

Trump on the wrong side of energy history
May 10, 2017 by Allan Hoffman

His most recent energy appointments show that president Trump insists on moving the U.S. away from clean energy. This goes against the global trend and will put this Administration on the wrong side of energy history, writes Allan Hoffman, a former official at the U.S. Department of Energy and contributor to a new handbook on the history and future of solar power.

Watching the Trump Administration evolve (I write this a few days after its 100 day anniversary) is a painful and scary activity.

As I wrote in a commentary for Energy Post on the Administration’s first week: “.. we do already know a few things: the next few years, with a Republican House, Senate and White House, will be a real test of the Republican Party, where party loyalty in a number of cases will come into conflict with national values and interests. Checks and balances among the three branches of the U.S. government, a pillar of our form of democracy, will be tested as never before in my lifetime. Not only was the recent election a test of the American people but the next few years will be a test of our democratic institutions as well.”

What are my views now that the first 100 days have passed?
On the 102nd day Yale University historian Timothy Snyder warned that “..it’s inevitable Trump will look to expand his power and take full control of the government by declaring a state of emergency sometime next year. The reason I think that is that the conventional ways of being popular are not working out for them.”

This is not the first time I have seen or heard such speculation, sometimes in the media and most immediately from an older friend who grew up in Europe during his most formative years. I take these comments seriously as I recognize that democracy is vulnerable to demagogues, as De Toqueville pointed out almost two hundred years ago, but cannot yet bring myself to believe that that is where we are today.

Unusually outspoken

My hesitation is bolstered by the behavior of our courts and our media in these past 100 days, two pillars of our democratic system. The courts have resisted what they have perceived as Trump’s unconstitutional initiatives on immigration and sanctuary cities, and the media have been unusually outspoken on Trump’s inconsistent statements and lies. Where I have been extremely disappointed is in the behavior of our legislative branch, controlled by a Republican Party leadership that has often put party and political advantage over national interest.

I also stated in the earlier commentary my belief that we would learn a lot from President Trump’s appointments to his cabinet, White House staff and to the 4,000 positions in the federal agencies and departments he controls. These have been, for the most part, highly discouraging.

While he has appointed a few experienced people to his cabinet and personal staff, his agency and departmental appointments have often gone to individuals who have expressed limited to no support for, and even hostility to, the missions entrusted to them. The case of Scott Pruitt at the Environmental Protection Agency has been well documented.

Lobbyist

Trump’s recent appointment of Daniel Simmons as the acting head of the Department of Energy’s Office of Energy Efficiency and Renewable Energy is another case in point. It puts this important office in the hands of someone who has, according to the Washington Post, “… questioned the value of promoting renewable energy sources and curbing greenhouse gas emissions… ”

The Washington Post writes that “Before Trump was elected, Simmons served as vice president for policy at the Institute for Energy Research, a conservative think tank that espouses fossil fuel use and opposes the international climate agreement that nearly 200 countries struck in Paris in late 2015.”

There is little doubt anymore that the world is moving inexorably to an energy system that relies less and less on traditional energy sources

The week before, Trump nominated David Bernhardt, a lobbyist who served at the Interior Department under George W. Bush, as Interior’s deputy secretary. Bernhardt was a partner at Brownstein, Hyatt, Farber and Schreck, a consultancy representing oil and gas firms, mining companies and agricultural interests.

This is in sharp contrast to the policies of the Obama Administration which sought to move the country onto a clean energy path and places Trump and his administration on the wrong side of history. There is little doubt anymore that the world is moving inexorably to an energy system that relies less and less on traditional energy sources such as fossil fuels and nuclear, and toward a clean energy system that relies increasingly on energy efficiency and renewable energy.

Many benefits

This is not an ideological position but one that recognizes the climate change and other environmental impacts of fossil fuel use, the costs and other difficulties associated with nuclear fission power, and the increasingly attractive economics and job creation potential of renewable energy technologies.

President Trump’s actions and appointments may affect the pace of U.S. movement onto this path, but he cannot stop it. Other countries are moving rapidly in this direction, recognizing the many benefits to be derived, and individual U.S. states will continue their encouragement of clean energy technologies. The U.S. Congress can enact policies that reverse this potential slowdown, or support it and take a chance that it will not be punished by American voters in future elections. Public opinion polls clearly indicate that this would be a foolish bet.
