Wind Power in View: Energy Landscapes in a Crowded World

Wind Turbines, Aesthetics, & Public Acceptance

Whether you love them or hate them, all agree that wind turbines elicit strong reactions, and the potential for conflict will only increase as wind energy’s importance grows.

Wind Power in View, a new book by Academic Press, tackles the thorny land-use questions raised by the booming wind turbine industry in Europe and North America.

Wind Power in View: Energy Landscapes in a Crowded World is an authoritative international collaboration examining the aesthetics of wind energy and the place of wind turbines on the landscape. Wind Power in View is the second title in Academic Press’ Sustainable World Series.

Edited by Martin J. Pasqualetti, Paul Gipe, and Robert W. Righter, Wind Power in View surveys where wind energy stands at the dawn of the new millennium, recounts some of the aesthetic objections leveled at the technology, presents case studies, and offers guidelines that could increase public acceptance of modern wind turbines.

Wind energy is one of the world’s fastest growing sources of energy, with the manufacture, installation, and operation of wind turbines now a multi-billion-dollar industry. Literally thousands of new wind turbines are sprouting from fields and backyards across Europe and North America every year. With such explosive growth, questions naturally arise about what they should look like and where they should and should not be installed. Wind Power in View offers a timely discourse by leaders in the fields of wind energy, planning, and aesthetics.

Wind Power in View is illustrated with color photographs of the good, bad, and ugly of wind power development on two continents. Illustrations include orderly arrays of wind turbines in Denmark as well as examples of industrial detritus abandoned on giant wind farms in California.

Wind Power in View contains both American and European Perspectives, incorporating chapters by four American and five European writers. The thought-provoking text includes full citations to encourage further research by academics, planners, and policy makers.

In Wind Power in View architect Christoph Schwan asks whether wind energy is merely a false solution to environmental guilt. German researcher Martin Hoppe-Kilpper recounts the inauguration of a locally-owned wind farm where villagers celebrate with “bier, wind, and würstchen”. Author Paul Gipe laments the toll wind development has taken on the California landscape while offering guidelines on how the industry can learn from its mistakes. English artist Lorry Short calls for a truly consultative process to incorporate the community in planning where wind energy is and is not acceptable. Award-winning architect Frode Birk Nielsen discusses the placement of wind turbines on the Danish landscape. Geographer Martin Pasqualetti examines the controversial development of wind energy near the resort town of Palm Springs, California. Historian Robert Righter reminds us that the thousands of farm windmills once dotting the American Great Plains in the 19th century were both reviled and praised. Only after their technological obsolescence, says Righter, have American farm windmills found near universal acceptance. Karin Hammarlund explores the degree of public acceptance of modern wind turbines in Sweden and what factors most influence the public’s reaction. Gordon (Corky) Brittan calls for creative approaches to wind turbine design and argues for more local control in wind development.

As the world increasingly turns toward renewable sources of energy to avert global warming, what will wind’s role become? Will it be welcomed as the “green savior” that some see, or will it be fought as vigorously as nuclear power? The outcome could well hinge on how the public views wind energy on the landscape. Wind Power in View takes a sober look at what people see when wind turbines appear in their midst.

“The ultimate account of how we can take the breeze that washes daily across our planet and use it to power our lives. There’s something quietly thrilling about this book!”

—Bill McKibben, author of Deep Economy: The Wealth of Communities and the Durable Future

“A massive expansion of wind power is necessary for the transition to 100% renewable energy if we want to mitigate climate change and avoid conflicts over resources. Paul Gipe’s book shows the path forward. It is a masterwork.”

Hans-Josef Fell; former German MP, co-author of Germany’s Renewable Energy Resources Act, and President of the Energy Watch Group

“No one knows more about the promise and pitfalls of wind power than Paul Gipe. With stunning photographs, accessible writing, and an eye for fakery and hypocrisy, he has produced one of the finest books on wind power available. Truly a masterwork. We owe him a great debt as we take the first steps toward a more sustainable energy future.”

—Martin J. Pasqualetti, Professor in the School of Geographical Sciences and Urban Planning, Arizona State University and author of The Renewable Energy Landscape

“This is the most comprehensive and best-informed book on wind power I know of, and its focus on developing wind energy outside the purview of the big utility companies is unique and subversive. Paul Gipe has done us all a great service.”

—Richard Heinberg, Senior Fellow, Post Carbon Institute and author of Our Renewable Future: Laying the Path for 100% Clean Energy

“Germany’s Energiewende–its energy revolution—is due to thousands of citizens working together in a grassroots movement. Paul Gipe shows how the energy and enthusiasm of the people created a technology that grew from the bottom-up–not the top down. An important book and an essential message.”

—Hermann Albers, President, German Wind Turbine Owners Association (BWE)

“Paul Gipe brings over three decades of wind energy experience to bear in this masterful one-stop compendium containing everything we want to know about wind energy.”

—Mark Jacobson, Professor of Civil and Environmental Engineering, Stanford University

“Over the last 40 years, I’ve learned more about wind power from Paul Gipe than from any other source. Now he has put it all into one splendid new book. Wind Energy for the Rest of Us expertly addresses every question about technology, policy, and economics that is worth answering.”

—Denis Hayes, Chair of Earth Day 2020 and former director of the National Renewable Energy Laboratory

“Gipe’s call for an ethical energy policy in Wind Energy for the Rest of Us is a message that North American politicians should heed. The people deserve nothing less.”

Glen Estill, Past President of the Canadian Wind Energy Association, and successful wind entrepreneur

“Gipe has been one of the leading voices for wind energy in North America . . . effectively straddling the line from technical to political while communicating wind’s promise to the general public.”

—Tim Weis, former Policy Director, Canadian Wind Energy Association (CanWEA)

“Paul Gipe has been involved with wind energy since its revival in the late 1970s. His extensive experience makes him uniquely qualified to be the author of this fascinating and informative book.”

—Tom Gray, former Executive Director, American Wind Energy Association (AWEA)

Wind Energy for the Rest of Us is the most definitive account of wind energy you are likely to find. Pure and simple. It doesn’t matter whether you are an engineer, lobbyist, manager, academic, wind developer, or just somebody who wants to know about wind power, this book is the best source for helping you understand the technology, how it developed, where it’s going, and how it fits in with the world. Paul Gipe is the master of wind energy, and this book is his masterpiece.”

David Toke, Reader in Energy Politics, University of Aberdeen, Scotland

“The wind is like the sun, a gift from the heavens. In all languages the wind is identified with the spirit–and it blows for everyone. This impressive work by Paul Gipe shows that the winds of change are unstoppable and that they are there for all of us. If we want a world free from conflict, we must build as many wind turbines as fast as possible–each turbine a sign of peace.”

Franz Alt, journalist, theologian, and author of Der ökologische Jesus and Krieg um Öl oder Frieden durch die Sonne

“Few are more qualified to write a book titled Wind Energy for the Rest of Us than Paul Gipe. He proves again that he is one of the world’s most knowledgeable authorities on wind energy. More importantly, he understands the politics behind energy policy. Following his recommendations would not only create a better environment, but also lead to a fairer and more just world.”

—Stefan Gsanger, Executive Director, World Wind Energy Association

“I have only skimmed the surface, but I can already understand what a masterpiece this is on so many counts.

It is an essential testimony to the sheer determination of a silent army of practical dreamers, to all those who mobilized and shared their ways and talents to make wind technology the spearhead of a renewable energy world and took it on an absolutely exemplary course.  

What a phenomenal historical account of all international efforts leading to a world class industry committed to building energy sustainability.

It is a fantastic tribute to the electricity rebels that succeeded in making this formidable endeavor possible over…what … say 50 years. 

What the world class wind industry as we know it today means for the world economy is that it can get out of its fossil fuel dependence in, certainly less than…, 50 years.

This book clearly demonstrates why those who think they can derail the Paris treaty are irresponsible fools. Now is the time for all citizens to raise the issue of sustainable energy in every town hall across North America.  

This is truly a colossal work.”

—Bernard Saulnier, ingénieur, l’Institut de recherche d’Hydro Quebec (retired)

“Wind Energy for the Rest of Us is more about sociology than technology; an environmentalist’s ‘sat nav’ for living more lightly on a confused planet. Gipe uses wind as a metaphor for society’s efforts to harness the unlimited renewable resources that surround us. Huge technology leaps, cutting the cost of wind power, become portals through which whole energy systems are set to become more accountable, democratic, and sustainable. Gipe’s is a book for those who grasp that it’s never too late to be all the things we ever wanted to be. Read it. Ride its currents. Then use it to change everything. This is our moment.”

Alan Simpson, former British MP, climate campaigner and energy policy advisor

Gipe is “One of the doyens of the wind engineering profession. He’s in a class by himself!”

—K R Rao, author of Energy and Power Generation Handbook: Established and Emerging Technologies and the forthcoming Wind Energy for Power Generation: Meeting the Challenge of Practical Implementation.

“The Gold Standard for wind power. . . The pix are fabulous. . . An absolute tour de force!”

—Ron DiPippo, emeritus professor of mechanical engineering, University of Massachusetts Dartmouth, and author of Geothermal Power Plants, 4th Edition, 2016

“They say that a good book should always tell a story. And this is true for this book by Paul Gipe. . . And it is a book of excellent graphic and textual quality. Something that’s becoming rare in a time when publishers provide less and less editorial services. . . This is one of the best books on renewable energy that I happened to read in recent times.”

Ugo Bardi, professor of physical chemistry at the University of Florence and author of Extracted: How the Quest for Mineral Wealth is Plundering the Planet and Cassandra’s Legacy

“I am very impressed with your book. I started reading the Friedrich-Wilhelm-Lübke-Koog chapter and I must tell you that you captured our spirit perfectly–it was fun reading it. I am in awe of your ability to gather all these facts and get them right!”

 —Hans-Detlef Fedderson, director, ee-nord and founding member of Bürger Windpark Lübke-Koog

“This is a brilliant book on wind energy, by far the best I have ever seen. It’s considerable depth and breadth ranges across the broad spectrum of wind energy. The writer’s comments and insights on siting concerns will provide those who may resist the development of wind energy with realistic perspectives on any issues that may be of concern, such as shadow flicker or noise.

The design of the book makes it a delight to browse through, the balance of pictures, drawings, charts, and writing is both easy on the eye and delightful. Don’t be put off by the 500+ pages, this book is a pleasure to read in its various sections – each standing on its own yet part of a whole. For example, the fine chapter on community wind. The author brings a lifetime of experience in energy and wind energy in particular to his book. It is a book that he can be justifiably proud of.”

—Dermot McGuigan, author of Harnessing the Wind for Home Energy (1978) and a longtime renewable energy advocate

Buy the Book

“During our recent board meeting at the Danish Wind-Historical Museum, our chairman, Birger Madsen, said that he had just received a copy of your latest book, and was very impressed. I immediately ordered a copy, which arrived yesterday. I have copies of your previous book – however this latest is indeed a masterpiece-handbook. Many thanks.

—John Furze, active in Danish wind energy since 1965

Paul Gipe‘s new book is quite remarkable. At first glance, it looks as if it’s a huge technical manual that tells you everything you ever wanted to know about wind power, but when you dig in you find that it’s certainly that – but it’s also far more, and as well, it’s written in a very easy, conversational style.

So if you are entertaining any ideas about investing in, building, or promoting wind energy, Paul Gipe’s book is an absolute must. Got questions about the best blades? Best towers? Price? Vertical axis? Rooftop turbines? Community ownership? Cooperatives? Setbacks? Micro-turbines? Energy production? Performance? Feed-in tariffs? It’s all here – every single thing you might want to know about wind energy, in meticulously researched detail.

Paul is not some journalistic observer of the wind scene – he has lived it, done it, campaigned for it and worked extensively on it for decades, and he really knows his stuff. Highly recommended.”

—Guy Dauncey, author of Journey to the Future and many other titles

“I just received your monumental book. It’s a sort of Britannica on wind energy!”

—Giuseppe Onufrio, Direttore Esecutivo, Greenpeace Italia

“Thank you, Paul Gipe, for pulling together the many faceted world of wind power. Anyone can read this thoroughly compiled description of how man has for many, many years utilized a resource. The author gets into the details explaining exactly the physics of transforming a stiff breeze into an electric current, the most basic component of our modern life. The comparison of different windmill designs should help interested participants in this alternative power source to choose wisely, avoiding undue monetary loss. Challenges to implementing wind farms such as noise, wildlife impacts and visual aesthetics are discussed, even an unexpected chapter about real hazards one should be aware of when working on a windmill. For the skeptics who have known only a life energized by huge utility companies, the author shows how Danes and Germans are plugging into a more independent power grid system. Furthermore, the potential of how small communities or cooperatives in the United States could possibly profit by utilizing this energy is put forward for those desiring to reduce reliance on large polluting carbon-based power plants. Our modern society, for it to function as it has become accustomed, demands electricity. This book is a wonderful window into how our presumed lifestyles can less harmfully coexist with our environment. “

—John Ewing, Fort Wayne, Indiana

“This is a wonderful book! I am glad–and a bit proud too–that our locally-owned wind company, Windkraft Diemarden, is so well presented. The pictures may convince those who can’t believe, or will not believe, that dismantling (of old wind turbines) is really possible. Thus, your book will clear up some confused minds. For “the rest of us” the book gives valuable information supported by high-quality photographs. And the fine layout invites people to read it. It is the first book about renewable energy I’ve seen with a world view.”

—Gottfried Wehr, member, board of directors, Windkraft Diemarden a 365 member community-owned wind farm that generated nearly 22 million kWh in 2016

Wind Power for the Rest of Us” is an outstanding piece of work. There is a great deal of detail in the book I was not even aware of. Wind Power for the Rest of Us is now my go-to resource on wind power.”

—Bill Powers, Powers Engineering and an authority on renewable energy in California

“I can’t thank you enough for writing such an inclusive book. As I approach retirement, I try to “pass-down” some of my lessons learned, but you did the ultimate and put it into a book.

—Neal Emmerton, Regional Operations Manager, Everpower and longtime wind plant operator

“Gipe has succeeded in presenting a complete, one stop resource for anyone interested in learning about wind energy from an objective and comprehensive point of view. His new book is comprehensive, yet the conversational tone allows for easy reading in spite of the detailed formulae and calculations. The use of the spreadsheets contained in the appendices and on the website are very powerful and serve to enhance learning and understanding. This book serves not only as a primer for the layperson, but has the depth to provide most of the answers needed by a professional in the wind industry. He has covered all the bases and then some.”

—Cris Folk, Renewable Energy Program Director, Madison College

“Paul Gipe’s monumental new book covers a lot of ground. Big turbines, small turbines, water-pumpers, early developments to the latest advances—whatever your interest—it’s all here in this comprehensive—and carefully researched book.”

—Greg Pahl, author of Power from the People: How to Organize, Finance, and Launch Local Energy Projects

“This is the most comprehensive book on wind energy you can find. Period. No one has more experience writing about the subject than Paul Gipe. This book is packed with everything you need to know, whether you are thinking about building your own small turbine or investing in the industry. Wonderful photos, illustrations, and charts help the information come alive, as does Gipe’s lively writing and a healthy dose of case studies—from wind energy pioneers to a group of nuns who wanted to generate power more in keeping with the Bible. This book is at once a powerful resource and an engaging read. It will help the reader get a solid foundation in this fast-growing, exciting source of clean energy.”

—Brian Howard Clark, journalist and author of Build Your Own Small Wind Power System

“Paul Gipe has done it again–straight talk on wind electricity from a wind journalist without peer. Gipe covers the important ground with clarity and detail, in a no-nonsense style that clears away the clouds of misinformation and hype too common in the popular and social media. Based on science and experience, grounded in a sensible environmental ethic, his newest book will stand the test of time.”

—Ian Woofenden, Home Power magazine senior editor, and author of Wind Power for Dummies

“Paul Gipe has been involved in the wind industry since the 1970’s, wrenching, writing, observing, critiquing, offering kudos and criticism where warranted. His book represents a lifetime of experience that is unmatched by others simply because few have the breadth of involvement that four decades brings. From small wind to megawatt turbines to the latest “thinking out of the box” breakthrough fantasy technologies, Gipe includes them all. Wind indeed is part of the solution.”

—Mick Sagrillo, Sagrillo Power & Light

“Gipe gives us the thrilling story of the social movement that created wind energy and enabled it to grow so rapidly—the movement that took power from the utilities and put into the hands of citizens and local communities. Read it, and become part of the movement!”

—Tore Wizelius, author of Windpower Ownership in Sweden: Business models and motives

“He must be powered by the wind himself this Paul Gipe. He endlessly shares the stories of those who have made wind energy work. He makes you believe in a sustainable future and feel the wind of change!”

—Søren Hermansen, Danish community power advocate on Samsø—the 100% Renewable Energy Island

“Paul Gipe’s written and spoken words have brought many into the world of wind power, both in North America and abroad. He’s much more than a journalist, he writes from first-hand knowledge of the wind industry where he’s helped define best practices and drive policy initiatives. The North American experience is very different from that of Europe. Paul has seen them both and can share their triumphs as well as their failures.”

—Lisa Daniels, Founder & Executive Director, Windustry

“Wind energy has a rich history and a wide array of technology and applications; Gipe covers it all. Anyone interested in wind will have this book on the shelf and refer to it often.”

—Brent Summerville, Technical Director, Small Wind Certification Council

“Wind energy is more important now than ever and Paul Gipe rises to the occasion with yet another comprehensive but highly readable briefing for all of us.”

—Hugh Piggott, Scoraig Wind Electric, Scotland

Since the mid-1970s I’ve followed the development of wind energy around the globe. During this time I’ve been a proponent, participant, observer, and critic of the wind industry. As an observer, I’ve traveled extensively reporting on the technology and how it’s being used. As a participant, I’ve installed anemometers in Pennsylvania, hunted windchargers in Montana, and measured the performance of small wind turbines in Cali­fornia. As a proponent, I’ve lectured about the promise of wind energy to groups from Vancouver to New Delhi, from Punta Arenas, Chile, to Husum, Germany. And as a critic, I’ve called some wind companies to task when their environmental practices were no better than the technol­ogies they intended to supplant.

In the early 1980s, I prepared a daylong seminar on the prospects and pitfalls of wind energy. An early version of this book, published in 1983 under the title Wind Energy: How to Use It, grew out of the course notes for these seminars.

At that time there was a chasm between the books written for back­yard tinkerers who wanted to build their own wind turbines and those books surveying the entire field of wind energy. There was no book that answered the questions people raised in my seminars about how they could obtain a working wind system and not an experimenter’s toy. Wind Energy was written to meet that need. The book was unique because it didn’t simply look at the technology. It gathered tips and advice from leaders in the field and offered practical guidance on how to select, buy, and install wind turbines—and how to do so safely.

Wind Energy was reissued in 1993 by Chelsea Green Publishing as Wind Power for Home & Business. The book became a staple of both homeown­ers and professionals interested in the subject. In 2004, Chelsea Green again published an extensive revision titled Wind Power: Renewable Ener­gy for Home, Farm, and Business.

Today wind energy is a booming worldwide industry, and with the heightened concern about climate change and energy security, this resur­gence of interest is here to stay.

Despite wind energy’s success—and the plethora of books on the topic—there remains a need for a frank discourse on how to wisely use the technology. For this reason, I have continued to edit and update the book. After a decade on the market, it was time for another extensive revision.

Each new edition has reflected changes in both my view of how best to use wind energy and in the technology available. This version incorpo­rates the lessons I’ve learned from more than three decades working with wind energy. It also introduces the concept of “community wind” where groups of people invest in large wind turbines that produce commercial quantities of electricity for sale to the utility company. While a seemingly novel concept in North America, it is quite common in Denmark and Germany. In community wind, farmers, small businesses, and groups of community-minded citizens band together to develop—for profit —“their” wind resources. As Germany’s electricity rebels say, “Renew­able energy is far too important to be left to the electric utilities alone. We have a responsibility for our own future. We can and will develop our own wind resources for our own benefit and for the benefit of our communities.” By proving that it can be done, Germans and Danes have served as models for us in North America as well as for others around the world.

Soon, I hope, we’ll see communities across the continent clamoring for the right to connect their wind turbines to the grid—and their solar panels and biogas plants as well—and be paid a fair price for their electricity.

This book is not by any means exhaustive, nor is it intended to be. In the more than three decades I’ve worked with wind energy, the field has grown so vast that it’s no longer possible to confine the technology within the covers of one book.

In 1983, I sought to help newcomers to wind energy avoid the mistakes that I and others had made and to spur development of this renewable resource. Wind Energy for the Rest of Us seeks the same end.

Bon vent! (Good wind!)

Paul Gipe

Bakersfield, California

No one can write a book on a subject that crosses so many disciplines as wind energy without the help of numerous contributors. Moreover, after a three-decade career in wind energy, I’ve had the good fortune to meet many of the visionaries in the field, and their advice and commentary are peppered throughout the text.

My work has been influenced by so many people that in writing these acknowledgements I am certain to forget someone that should be included. Rather than throw up my hands in despair and simply issue a heartfelt thanks to all those who have helped in one way or another, I want to thank as many of those as I can remember. For those I’ve overlooked, please accept my apologies.

I am especially indebted to Vaughn Nelson at West Texas A&M University’s Alternative Energy Institute (AEI). Vaughn first taught me the importance of swept area and how to quickly cut through the hype that often surrounds new wind turbines. AEI’s Ken Starcher has been invaluable for his technical expertise as well as his old-fashioned common sense.

My thanks to Mick Sagrillo, Sagrillo Power & Light, and Hugh Piggott, Scoraig Wind Electric, for answering my many questions on battery-charging wind systems. Both Mick and Hugh are fonts of prac­tical, hands-on knowledge of small wind turbine design. I’ve used their astute observations liberally throughout this book.

Jim Salmon, Zephyr North, and Jack Kline, RAM Associates, were instrumental in the chapter on wind resources, as were Dave Blittersdorf, AllEarth Renewables, and Ken Cohn, Second Wind.

Small wind turbine manufacturers worldwide deserve a note of appre­ciation for responding to my frequent queries about their products. Over the years, Mike and Karl Bergey, founders of Bergey Windpower, have been notably forthcoming. David Sharman, Ampair, and Brent Summer­ville, Small Wind Certification Council, have both been a great help in understanding the arcana of certifying small wind turbines.

I again extend my gratitude to Preben Maegaard and Jane Kruse of the Folkecenter for Renewable Energy and to the people of Denmark for a fellowship that allowed me to study the distributed use of wind energy in northwest Jutland. It was at the Folkecenter where I first learned how to use a griphoist to install small turbines.

Page 57. Figure 4-7. MAN WKA 60. Würst is mispelled. It should be Wurst in the singular. Apparently my German isn’t up to the task here and again on page 412.

Page 78, South of the Border (Enercon) sidebar. Herr Wobben’s first name is misspelled. It is correct, Aloys, elsewhere.

Page 148. FloWind description top-right column. 17-meter rating reversed with 19-meter rating. 17-meter is 44 mph, 19-meter is 38 mph. Table 6-1 is correct.

Page 169. Figure 6-31. Tip Speed Ratio, not Ration.

Page 193. Figure 8-3. The colors in the legend are reversed. This is correct in the digital version.

Page 256. Corrected text. First para. following Figure 11-3.

Compare the annual specific yield in Table 11-2 with that in Table 11-1 for an average annual wind speed of 6 m/s: 400 kWh/m²/yr to 570 kWh/m²/yr. The new, high-performance household-size turbines are nearly 50% more efficient at capturing the energy in the wind than those wind turbines available in the 1990s represented in Table 11-1.

Page 476. Table 19-11. Turbine on table title is misspelled as Turbone. This is correct in the digital version.
