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.

‘The Sun Is Rising in Africa and the Middle East: On the Path to a Solar Energy’ Future’ Is now available

ON March 26, 2018 Pan Stanford Publishing released the 9th book in its renewable energy series: ‘The Sun Is Rising in Africa and the Middle East: On the Path to a Solar Energy Future’. It was authored by Peter Varadi, Frank Wouters, and me, and includes important chapters by contributors Anil Cabraal, Richenda Van Leeuwen, and Wolfgang Palz. It is available in a paperback, Kindle, and digital format and can be found on several bookseller websites.

Summary (from back cover of book)
Both Africa and the Middle East are blessed with enormous solar energy resources. Electrification is an urgent need in Africa, where many of its 54 countries are among the world’s fastest-growing economies, but where half the population still has no access to electricity. Solar energy is seen as the fastest and cheapest path to addressing this need. Oil-rich countries in the Middle East are turning to solar energy to meet the growing domestic demand for electricity, freeing up hydrocarbons for export. This book describes the energy transition in Africa and the Middle East, from dependence on fossil fuels to increasing reliance on solar energy. The authors were assisted by the contributions of top experts Wolfgang Palz, Anil Cabraal, and Richenda Van Leeuwen in their efforts to provide a sound basis for understanding where solar energy is heading in these two important global regions.

I also include here the book’s more expansive Epilogue:

Epilogue

An energy transition that took its first tentative steps in the latter part of the 20th century is now unfolding rapidly in the 21st century. It will have a major impact on Africa and the Middle East along with every other part of the world. It is a transition from dependence on carbon-based fuels such as coal, oil, and natural gas to the utilization of renewable energy technologies such as solar, wind, biomass, geothermal, hydropower, and ocean technologies. All, but geothermal, which is derived from the radioactive decay heat in the core of the earth, and tidal energy caused by the moon, are direct or indirect forms of solar energy. Just as we have experienced a fossil fuel era for the past few hundred years—today the world is still more than 80% dependent on such fuels—we are now embarking on a solar energy era that taps into the enormous amounts of energy received by the earth from its sun 150 million kilometers away. To put this in context, while the earth intercepts approximately 6 million exajoules of solar radiation each year (1 exajoule = 1018 joules), and the total global energy consumption is about 600 exajoules, the fraction of the sun’s radiated energy intercepted by the earth’s disk is only 4 parts in 10 billion. The issue before us is how to utilize this diffuse energy source cost-effectively and meet, in an environmentally friendly way, the needs of an expanding global population

We are transitioning from relying on ever-scarcer sources of fossil energy to an era of unlimited, clean, and cheap energy, brought about by modern technology. This transition, which can also be seen as an energy revolution, has major implications for bringing energy services not only to urban and peri-urban areas of Africa and the ‘Middle East but also to those rural, off-grid areas currently without access to electricity. Both Africa and the Middle East are blessed with enormous solar resources, which are just beginning to be tapped, providing an opportunity to improve the lives of hundreds of millions of people. Efficient and cost-effective solar solutions and novel business models enable previously unserved people to leapfrog straight into the future of energy. This book explores some of these opportunities that will transform Africa and the Middle East in the decades ahead. It is an exciting time in the energy history of the world, and Africa and the Middle East will be important playing fields in creating that new history.

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.

Trump On the Wrong Side of Energy History

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.

Editor’s Note

Allan Hoffman is author of the blog Thoughts of a Lapsed Physicist. He is a former Senior Analyst in the Office of Energy Efficiency and Renewable Energy at the U.S. Department of Energy (DOE) and physicist by training.

Hoffman is a contributor to a new comprehensive handbook, Sun Towards High Noon, edited by solar pioneer Peter F. Varadi, which details the meteoric expansion of the solar (PV) industry and describes how solar power will change our energy future.

An Interesting Interview with President Obama’s Science Advisor

Dr. John Holdren has served as President Obama’s Science Advisor and Director of the White House Office of Science and Technology Policy throughout the eight years of the Obama presidency.  I found the following interview of Dr. Holdren of great interest and reproduce it here for the benefit of this blog’s readers. It was conducted by Kiley Kroh, Senior Editor of the e-journal ThinkProgress and first published in that journal on December 21, 2016.

Can the world fight climate change in the era of Trump? Obama’s science adviser thinks so: Dr. Holdren weighs in on climate science, denial, and why every president needs a science advisor.

Dr. John Holdren and President Obama

When asked what has kept him in his job for so long, the longest serving presidential science adviser in history answered without hesitation.
“What kept me in the job is working for the most science savvy president since Thomas Jefferson,” Dr. John Holdren said. “And in a situation where there’s a lot more science to be savvy about today than there was when Thomas Jefferson was president.”
Holdren was clear that the man in the Oval Office, that man’s respect for science and innovation, and his desire to elevate those fields across government all made the past eight years a once in a lifetime opportunity.
“I would not have jumped off this ship for anything,” said Holdren.
But the winds of change are blowing hard. President Barack Obama will vacate the White House in a month and the tenor of the group assembled to replace his administration, particularly with regard to science policy, could not be more different. President-elect Donald Trump has repeatedly called climate change a “hoax” and recently said “nobody really knows” whether climate change is real. (In reality, scientists are quite certain it is both happening and largely the result of human activity.)
Trump has already amassed an alarming number of people who reject the scientific consensus regarding climate change, have deep ties to the fossil fuel industry, and are quite clear regarding their intent to undo or weaken the Obama climate legacy. His transition team has asked the Department of Energy to name staff who worked on Obama administration climate policy, and pressed the State Department about its international environmental spending.
In the face of this dramatic shift, the scientific community is bracing itself for an administration that could be dismissive, or outright antagonistic, towards science — some are even going as far as to copy government climate science data on independent servers to ensure its preservation.
Holdren is nevertheless optimistic that the forces moving the world toward progress on climate change are stronger than the pull of denial, and that the advancements made in the past eight years will serve as building blocks rather than targets. While as a political appointee he’s prohibited from discussing the policies of the president-elect, he had a lot to say about climate denial, the importance of his position, and where we go from here. Read on for the highlights from our recent interview.
So much of what you were able to accomplish seems driven by a president who really prioritized science and gave it the funding and attention it deserves, so what happens to all of these initiatives moving forward?
I can’t speculate about the next administration but I will say this: First of all, the issue of addressing the climate challenge should not be a partisan issue. It’s about the economy, public health and well-being, national security — these are not fundamentally partisan issues, so one has to hope that that will increasingly be recognized.
The second thing I’ll say is that a lot of the progress is being driven by forces that are not fundamentally policies of the federal government. I think the two biggest drivers of progress on climate change around the world today are that the symptoms of climate change, the damages from climate change, are becoming ever more apparent. And the opportunities to do something are also growing — in substantial part because clean energy is getting cheaper. That’s going to be extremely important moving forward, regardless of what government policies do or don’t materialize in the United States.
If the U.S. is no longer at the forefront pushing climate commitments at the international level, is it your sense that China is going to step up? Are there other countries you’re looking to?
Let me be clear, I very much hope the United States will continue to carry out these forward-leaning actions to reduce emissions and build preparedness and resilience, because I think it makes great sense environmentally and economically. But if we don’t, I do believe most other countries will continue with their efforts in this domain because, again, they understand it’s in their interest to do so. China’s already stepping up.
But I don’t think for a minute that if, for one reason or another, the U.S. reduced its level of activity in this space, that China would reduce its [activity]. I expect that the European countries, who are themselves experiencing the impacts of climate change, will stay the course; I think Canada will stay the course; I think many of our friends in Latin America will stay the course; I think India will stay the course.
Everybody is suffering from climate change, and no matter how much hand-waving a few folks may want to continue to do about how it’s not all proven, the fact is everybody around the world now understands that it’s real, that human activities are causing it, and that aggressive action is required to fix it.

You mentioned your belief that several major countries will continue to stay the course on climate action. Can you talk about the course we’re on globally? Obviously, the Paris agreement was a significant achievement, but how do you view that in terms of what we need to be doing to stave off the worst impacts of climate change?
First of all, as you know, it’s not enough. Everybody who looks at this problem realizes Paris is a down payment on a longer term strategy to reduce emissions much more drastically. By the end of this century, we have to be at zero emissions; in fact, we should be at zero emissions, net, before the end of this century if we want to avoid the most catastrophic consequences of climate change. The key point about Paris, really, is that it is the biggest step in the right direction the world has ever taken, and it was taken much later than those of us who watch this problem closely would have wished. After 2030, when the most far-reaching of the Paris targets occur, we’re going to need a very powerful encore; we’re going to need much deeper reductions going forward, we’re going to need better technologies to do it.
One of the things I’ve found a little irritating about the climate science discussion over the years is the discussion about when will we reach dangerous human interference in the climate system. I think it’s very difficult to argue climate change isn’t already dangerous. We’re not really in the business any longer of trying to avoid dangerous climate change — we’re already in dangerous climate change. We’re trying to avoid catastrophic climate change and I think it would be better to be clear about that.
“We’re not really in the business any longer of trying to avoid dangerous climate change… We’re trying to avoid catastrophic climate change.”
I know you can’t speculate on the incoming administration, but it’s my sense the tide was turning over the past few years to make it less acceptable for a public figure to deny climate change. What is it about climate denial that makes it so difficult to overcome?
I think it’s a misconception that’s driven a lot of the expressions of doubt about the science — that folks don’t want to accept the science because they think accepting it is tantamount to accepting a draconian regulatory regime on our energy choices. The reality is that there are many ways to skin this cat. As economists from all parts of the political spectrum tell us the most efficient ways to reduce greenhouse gas emissions would be a market-based approach, putting a tax on carbon emissions that could be offset by reductions in other taxes.
If you accept the science, you might prefer to accept a carbon tax or a cap-and-trade approach, which does more or less the same thing under different administrative arrangements. Either can be adjusted over time to get the emissions result that you want. And that’s basically a market-based approach rather than a regulation-based approach; it should make Republicans happy.
I’m sure you’ve seen the various efforts to sell Republicans and conservatives on the solutions — clean energy, even a carbon tax — without emphasizing or asking them to accept the climate science component. Do you think that can work?
I think ultimately we will not do enough without accepting the reality of climate change and the need to address it in a more serious way going forward than we have in the past. We will do a lot of things that go in the right direction based on market forces alone — as I noted before, basically, clean energy in many of its manifestations is getting cheaper. But I don’t think the market alone, without a price on carbon or its less efficient equivalent in a regulatory approach, will get us as far as we need to go.
In light of the reports regarding the fear in the scientific community about a potentially hostile environment ahead, what is your advice for scientists trying to preserve their ability to do their jobs?
Climate scientists should keep doing their science and they should keep publishing the results, and keep talking about the implications of the results. And they should keep making their data available so others can check their results. But coming back to a question you asked earlier about what continues to drive so much of the rejection of scientific consensus, the phrase has been around for some quite time: “do you believe in climate change?”
The notion that this is a matter of belief rather than respect for the conclusions of an expert community — this is not a matter of belief. Climate change doesn’t care whether you believe in it or not. It’s going to keep going.
In terms of big signs of climate disruption, what’s happening in the Arctic is one of the most alarming stories of the year. Can you talk about that, and any other major signs you’re following?
The Arctic is not only experiencing climate change much more rapidly than the rest of the world, but the consequences don’t stay in the Arctic. As we thaw permafrost, we are increasing the release of carbon dioxide and methane from the decomposition of organic matter. Wildfires in the Arctic are burning unprecedented areas; even the tundra is burning now. Sea level rise, combined with loss of sea ice protection from waves, is causing drastic coastal erosion around the Arctic, and the mainly indigenous peoples who live in villages on the vulnerable coastlines are in many cases having to relocate. I will tell you now from rather extensive experience meeting with the people who live in the Arctic, there are no climate deniers up there.
“This is not a matter of belief.”
There are some other things that are starting to get the attention they deserve. One is wildfires; there’s really an extraordinary story, and a very dangerous one going forward. A second is the danger from extreme heat, and the circumstance that there are parts of the world where, already in the hottest months, in the hottest parts of the year, it’s not possible to work outside without dying because of the heat stress. You’re seeing larger and larger areas of the world, as we’re moving further into this century, where it’s going to be impossible to do outdoor labor for much of the year. This is really a stunning result.
The other one that I think is helpful in explaining to people that, despite the complexity of this system, there are certain things that can be understood in pretty intuitive terms, is the relationship between warming and torrential downpours. That was long predicted, but we’re now seeing these increases in torrential downpours and associated flooding across much of the world. People who have experienced flooding of a sort that never previously occurred in their lifetime are generally not among the deniers.
As you’re reflecting on your legacy and work, can you tell me why, from your perspective, it’s important for a president to have a science adviser and receive objective scientific advice?
First of all, the president needs a source of science and technology advice that’s independent of the agendas of individual departments and agencies. It’s very important that there be somebody close enough to the president to tell him or her scientific and technological insights that may not agree with the prior preferences of the president.
Being able to work for this president on these issues has been the highlight of my career, and I expect that a lot of what we have done will survive as building blocks of progress going forward.
