DISCLAIMER: I have never done a book review before. So if you have any suggestions please let me know. This might be a bit long so TL;DR: Read this book, very informative, you will not regret it.
I read with some enjoyment The Grid: The Fraying Wires between Americans and our Energy Future. An anthropologist by training, author Gretchen Bakke is currently a Senior Fellow at the Institute for Advanced Sustainability Studies (IASS) in Potsdam, Germany. This is Bakke’s fourth book – the first three focused on anthropology and the human-environment system, so this offering branches out from her comfort zone. Bakke is an exuberant writer, who presents unexpected interactions and different ways of looking at things. This book is directed at inquisitive readers who are interested in things such as sustainability, alternative energy, and the complexities behind things we take for granted. The purpose of this book is to bring her readers to the understanding that last century’s marvel of engineering does not meet our needs today, and that we need to reinvent the grid to meet the changes that a cleaner, more energy-diverse, future will bring.
The title of this book is very evocative. The short title, The Grid, simply tells readers to expect a discourse on the electric infrastructure. However, the subsequent subtitle hints at what the reader might expect to encounter in the book. The “fraying wires” tells readers up front that the author believes all is not well with the grid. The “energy future” hints at changes that need to be made. It is not clear from the subtitle alone whether those needed changes are to maintain the status quo, i.e., if we need to physically repair the infrastructure that has frayed, or whether it refers to adaptations we need to make as energy and electricity sources have been expanded and redefined in ways that do not fit well with the current way the grid exists and functions.
Bakke’s writing in this book is generally fun and engaging. Words are selected to help paint a visual picture of the issues and concerns that she raises. She uses a very broad vocabulary; some of the words seem to be self-generated, such as “ingigliated,” so readers might want to bone up on using context to define words, or keep a dictionary on hand. But this does not interfere with the story she is telling, and helps keep readers’ attention. Bakke presents the grid and how it works (or does not work) in a style that is interesting to read. However, she tends to skip around a lot, and this can lead to the perception of a lack of cohesion throughout the book.
The basic premise of the book is laid out in the introduction: Not only is the grid beginning to fail to reliably provide electricity safely and efficiently, it is in no way suitable in its current configuration for the green energy that is soon to come its way en masse. When people talk about going green, when it comes to energy what they very often fail to realize is that there is a massive obstacle to this desired, even needed, change to our power generation methodologies. The grid, the electrical delivery system for the energy we use -- whether coal, nuclear, hydroelectric, or solar -- is not only crumbling, but it is unsuited to "green" energy. For example, the grid does not like when, a cloud moves in front of a solar energy production array and causes a massive decline in energy output; the grid does not like when the wind suddenly stops blowing and the wind farm sits motionless. The grid is designed for a constant flow of energy, always the same voltage, always the same speed. Bakke argues that in order to effectively utilize "green" energy on a wide-scale basis, one first must look at the delivery system. If our energy delivery system is based on steady power from 20th century fossil fuel and nuclear power plants, how do we expect it to properly utilize new power generation methods from the 21st century?
The meat of the book begins with an excellent discussion about the author’s trip to something known as “Grid Week.” Thousands in the energy production business along with politicians, educated peoples, and many others attended this weeklong event. I think that the most important sentence of the book is found on page 7: "This is our grid in a nutshell: it is a complex just-in-time system for making an almost instantaneously delivering a standardized electrical current everywhere at once." After reading this book, I agree with this. If you take away nothing else from this book, it should be that the grid is a massive behemoth desperately in need of some money, love, and attention, and that if we want to “greenify” our energy production, we need to first work on the grid, for it is not meant for the “green energy” world that is coming. The background in Chapter 2 about the development of electricity and early grid systems, and the complexities that ultimately led the many grid companies to be consolidated into a single system, helps the reader of any background, to easily understand the science along with the people behind these early developments. It remains clear that the greatest advancement during the early stages of the grid was not on the technology side of things, but on the business side: It could be argued that one Samuel Insull single-handedly created the grid that we know today when he took the reins of Chicago Edison, one of Thomas Edison's many franchise cities, wherein the grid was in a pickle. The greatest problem Insull had to solve was to deal with the very nature of the business of energy production. In order to run a central power station efficiently enough to make money off the sale of the electricity that it generates, it must run consistently throughout the 24-hour day. But energy demand is not constant! Insull had to find a way to encourage people to use electricity throughout the day in a more or less consistent manner. Further, the power plants run more efficiently if they are running full bore all the time. Therefore it was his primary interest to engineer a scheme that would make this happen. By making electricity cheap, everyone would use it, keeping demand up, and ultimately, greating a monopoly for Chicago Edison! The scary thing that occurred to me as I read this chapter is that the grid that was built back in the Insull days is basically the same one we have today! It is a very old grid, and it is not getting very much attention, which is a disaster, given how much we rely on it.
At this point, Bakke introduces the reader to the growing environmental movement in the 1970s in the United States, and how the adoption of the Public Utitlities Regulatory Policies Act reduced the monopsony powers of the utilities. This allowed small energy companies, as well as individuals with solar or other alternatvie energy generation systems to generate their own power, selling any excess to the local utility. This chapter may be interesting to readers with a political bent, but failed to capture my interests, although for some reason I did not quite follow, it segued into a lengthy discussion about wind power. Whilst interesting in its own right, it detracted from the main message of the chapter. The next chapter includes a riveting tale of how a sagging wire, over grown foliage (this causes the most number of blackouts and is the single greatest threat to our grid), and a computer bug, blackedout the entire East Coast and parts of Canada for 2 days, affecting over 50 million people. So great was this blackout it appeared as a visible dip in that year’s GDP, about $6 Billion in lost revenue. This exemplifies how tied the nation now is to the grid and to a steady supply of electricity.
The author discusses the advantages and concerns with smart meters to normalize energy uses, as well as microgrids, and how advances in microgrids can help improve the reliability of the primary grid. But here, towards the end of the book, she introduces the importance of developing effective and efficient means of storing energy, especially as we bring more renewables online that do not allow continuous energy generation, such as solar and wind power. This second to last chapter is a very useful deep dive into some of the tech currently out there.
Overall, I recommend this book. Dr. Bakke did a good job explaining in a simple but effective manner the technology, physics, people, and history that went into the grid’s creation and use up to the modern day. She stays amazingly neutral on politics and clearly presents the facts. However, she sometimes seems to lose track of the purpose of writing this book, and it is unclear overall whether she feels green energy, and the storage of said energy, is the holy grail for meeting the nation’s electricity needs or the final nail in the coffin of the grid. Decide for yourself: The book is available from booksellers on-line. ISBN: 978-1-63286-568-7.
