Product Description
For anyone who is trying to keep up with the extremely rapid developments in the biodiesel industry, the second edition of Biodiesel: Growing a New Energy Economy is an invaluable aid. The breathtaking speed with which biodiesel has gained acceptance in the marketplace in the past few years has been exceeded only by the proliferation of biodiesel production facilities around the United States–and the world–only to confront new social and environmental challenges and criticisms.
The international survey of the biodiesel industry has been expanded from 40 to more than 80 countries, reflecting the spectacular growth of the industry around the world. This section also tracks the dramatic shifts in the fortunes of the industry that have taken place in some of these nations. The detailed chapters that cover the industry in the United States have also been substantially rewritten to keep abreast of its many new developments and explosive domestic growth. An expanded section on small-scale, local biodiesel production has been added to better represent this small but growing part of the industry. Another new section has been added to more fully explore the increasingly controversial issues of deforestation and food versus fuel, as well as GMO crops. The second edition concludes with updated views on where the industry is headed in the years to come from some of its key players.

Below is my favourable take on Greg Pahl’s “Biodiesel”:
Diesel-powered vehicles and equipment are everywhere, and are likely to continue to exist for years, if not for generations to come. Buses, trains, trucks, generators, and a growing number of automobiles use diesel fuel. Diesel engines tend to be more fuel-efficient, and last longer, than their gasoline-powered counterparts. Diesel engines get better torque than do gasoline engines, and devote more of their energy to propulsion (what we want), and less to wasted heat (what we don’t want). In summary, diesel engines have a lot going for them.
However, the challenge is that diesel, along with its cousin, gasoline, are fossil fuels, whose supplies are, by most reasonable estimates, finite and declining at rates greater than many of us feel comfortable to acknowledge. Diesel fuel, when burned by an inefficient engine, generates a lot of pollution, both real (e.g. particulate matter) and perceived (i.e. billowing clouds of smoke). Diesel has a bad reputation in some circles, and often this is deserved.
Enter biodiesel, a renewable alternative to traditional “petrodiesel”. Developed over the past several decades from various plant and animal “feedstocks”, biodiesel is a relatively clean-burning fuel that can either supplement or, in some cases, replace the non-renewable petrodiesel. For example, B20 biodiesel, which I use in my 2004 VW Golf, consists of 20% biodiesel and 80% traditional petrodiesel. Overall engine performance is as good as, if not better than, what would be experienced using pure petrodiesel. The greater lubricity of biodiesel prolongs the life of engines that use it; this attribute will grow in importance as diesel suppliers are encouraged or forced to reduce the sulphur content of the fuel… the lower the sulphur, the lower the lubricity.
Other big motivations for using biodiesel are that, as a locally-sourced form of energy, it reduces our reliance on oil from other countries; additionally, there is its tendency to emit fewer toxic substances than an equal volume of petrodiesel. Local farmers, supplying the soybeans or switchgrass that constitute the biodiesel feedstock to nearby refiners, stand to benefit financially. Even used vegetable frying oil from restaurants can be salvaged and, with minimal processing, converted to cleanly burning biodiesel.
Greg Pahl makes the technology of biodiesel production accessible to the layperson; those of us who struggled through high school chemistry can grasp the concepts that Pahl presents so clearly. In a nutshell, many plants that are the beneficiaries of photosynthesis, such as soybeans and canola, hold in their cells energy from the sun, in a similar way that oil in the tar sands holds energy from the sun in the form of plant and animal matter that lived millions of years ago, and has been compressed and preserved.
The future of biodiesel depends on a few factors: education of customers, and governments that offer subsidies to suppliers of “green” energy sources; a steady supply of biodiesel feedstocks, such as soybean oil, canola oil, used vegetable fryer oil, and even animal fat from meat renders; a corresponding steady price for such feedstocks, so that biodiesel production capacity planning can be done with lower risk; a relatively attractive price for biodiesel vis-à-vis petrodiesel prices; cooperation between the large and small biodiesel suppliers; and collaboration between biodiesel suppliers of all shapes and sizes with the traditional petrodiesel vertical infrastructure (from the extraction of raw crude oil, all the way to the retail pumps in your neighbourhood).
Unlike hydrogen technology, biodiesel is a relatively clean, renewable energy source that is in successful, widespread use today: entire school bus fleets in the US run on pure biodiesel, with positive performance results and, happily, lower engine maintenance costs. Politically, it is often a no-brainer for state and local governments to embrace biodiesel use, as it puts money in the pockets of local farmers, and the fuel can be used with no need to convert existing diesel-consuming equipment. However, the traditional petrodiesel industry may well balk at moves to support biodiesel proliferation, since this would dilute, figuratively and literally, the concentration of petrodiesel that its customers necessarily need to buy.
I highly recommend Pahl’s book. It provides a balanced view of the benefits and challenges that face biodiesel producers and users. Having said this, Pahl is a cheerleader for biodiesel, and justifiably so. It’s hard not to share his enthusiasm.

The author has done a masterful job of building the case for a serious exploration of a bio-based energy economy. The book has a friendly not-too-technical style and it’s incredibly well researched, carefully documented and very well organized. As an added bonus, Biodiesel starts off with an insightful forward by celebrated author and environmentalist, Bill McKibben.
After setting the tone for the book by bringing to light the potential crisis of Peak Oil, Pahl begins to delve into part of the solution as he leads the reader on a great story ride through the life (and death!) of Rudolf Diesel, to the early pioneers of biodiesel across the European eco-industrial landscape and back to the present day biodiesel industry currently emerging in the U.S.. The book is full of personal interviews with key players that brings this rapidly evolving world of agriculture, science and alternative energy to life. And Greg Pahl does an excellent job of providing a balanced look at both the possibilities and the social and environmental challenges of drawing increasing amounts of energy from the soil.
I’ve been pretty involved in sustainable development for years (and biofuels in particular) and I can only say that this latest book by the author is a real gift and a “must read” for anyone interested in or working towards a renewable energy future.

I’ve learned more about the history of the diesel engine and biodiesel after reading the first chapter of this book than I have in the two years since I started reading about biodiesel. Anyone wanting to know about the complete history of biodiesel should read this book! It’s obvious that the author has done his homework.

Greg does a great job of explaining what biodiesel is, how/where it came about, and why it is a good additive to our current petrodiesel. He also writes about what other countries are doing with and how they are (currently) ahead of the US in utilizing it. He also discusses other forms of alternative/renewable sources of energy. I would recommend this book as good reading, but I would probably recommend ‘Biodiesel America’ first….as it has a bit more current info than Biodiesel: Growing A New Energy Economy. But good reading nontheless.

I found this to be a very interesting book to read. I have known for sometime that diesel fuel could be made from hemp seed oil but this book breaks down the walls to ignorance and fills the void with useful examples of what could be happening and what is happening around the world. I strongly recommend this book as part of well balanced diet of alternative energy readings. My only real critisicm of this work is that there is nothing said about the potential of Hemp. The author writes an entire section about the oil to weight ratios of various seed stocks that could be used for fuel. Most noticably missing is the Hemp seed which grows in every client and produces a more abundent amount of oil by weight than all the others! Maybe the author did not know that the first diesel fuel was made from vegatable oils. Henry Ford found that Hemp seed oil was the best for making diesel fuel. I wonder, could this be a hang up caused by the current “Drug War”? It is a shame that a useful plant such as Hemp would be omitted from a work on Bio-Diesel.
Otherwise, this is a must read. As most of us are begining to realize, crude oil is going to run out. So the question of what to use for fuel next is not a matter of “IF” but “When” and we as a society need to find alternatives. Bio-Deisel has great potential.
The book is a smooth read. It is engaging and full of detail which is carefully sourced but not dry or boring. I enjoyed it very much.
