BIO-FUELS IN THE NORTHWEST by Greg Rock, co-owner of The Green Car Company and founder of Sustainability Watch, a consulting company specializing in peak oil preparation, energy production, transportation and green design.
Washington State is rich not only with hydroelectric energy, but also with a large resource base for wind, tidal and biomass energy. For the environment's sake, and because of the impending world oil production peak we must start taking a hard look at what energy resources will sustain the Northwest's culture, economy, and resources.
The world oil production peak will create a shortage of liquid fuels, and thus much of our initial focus should be on developing our renewable bio-fuel resources. Today bio-fuels are made from agricultural crops. Ethanol is made from corn and can be run in a Flex Fuel or converted gasoline vehicle. Biodiesel can run in any conventional diesel engine and is commonly made from soy beans. Both of these bio-fuels can be made from a number of different agricultural crops. In Brazil, the world's largest bio-fuel producer, they make ethanol from sugar cane which accounts for 40% of their fuel consumption. Here in Washington we can make biodiesel from Canola and Mustard seed crops.
Today many farmers are already growing these seed crops in eastern Washington as part of their regular crop rotation. Currently they are tilled under because there is no economic value in harvesting them. Both of these crops require seed crushers to separate the vegetable oil from the meal. The meal is full of the nutrients, and the oil contains the rich hydrocarbons used for fuel production. Seed meal is commonly used as a fertilizer or animal feed. Washington's mustard seed meal could actually be used as an organic pesticide pending EPA approval. This process, unfortunately, could take 5 years. It is essential to the economic success of biodiesel production that a market exists to sell the resulting meal from the oil production process.
Washington legislation just created funding for a few crushing facilities in our state. Once these facilities are completed and we streamline our agricultural practices we could compete with Iowa the largest producer of bio-fuel crops in the United States. Iowa currently ships raw soy oil, left over from animal feed production, all over the United States for biodiesel production. Almost all of the biodiesel available in the Seattle area comes from Iowa soy oil. What has been the result? Iowa currently has the fastest growing state economy and the second fastest growing average income. Washington State currently spends 9 billion dollars per year on petroleum fuel. Imagine if we could get that money to our local farmers and economy rather than Saudi princes and big oil companies.
There are many environmental benefits to burning renewable bio-fuels instead of fossil fuel resources. The biggest benefit comes from closing the carbon loop which significantly reduces our impact on global warming. When plants grow they absorb carbon dioxide from the atmosphere. Conventional fossil fuels are created through the accumulation of millions of years of carbon plant matter stored under high temperature and pressure in the earths crust. We have created a huge atmospheric imbalance because we have burned and released close to half of that million years of stored carbon matter into the atmosphere in a little over one hundred year
When we burn bio-fuels we are using our annual allotment of energy, and releasing only that carbon dioxide which was absorbed from the atmosphere earlier that year by the plant. Burning bio-fuels produce nearly a net zero impact on global warming. Some energy is burned, and carbon dioxide is released, during the production of these crops. The end result is that burning today's bio-fuels reduces your impact on global warming by 80-90%. For example, a Toyota hybrid Prius will produce 340% more carbon dioxide per mile than a VW Golf running on biodiesel.
Bio-fuels are not perfect, though, and there are many questions that need to be addressed particularly with our industrial agriculture system. What we have defined as efficient agriculture is producing high yields of food per acre. We have achieved this primarily through the introduction of fossil fuel derived pesticides and fertilizers. These chemicals are not only bad for the environment but they also require huge quantities of energy to produce. Now as we find ourselves running short of energy and in a situation where we will actually attempt to grow the energy we want, we will have to reanalyze how we define efficient agriculture.
Anytime we produce energy we need to think about how much net energy we produce. If one project produces 20 units of energy but requires 15 units of energy input to do so it is not as beneficial as a project that produces 10 units of energy but only requires 1 unit to do so. The first project produced 5 units of net energy while the second produced 9 units.
Our current agricultural system is geared towards high yields through large energy investments. This is not the best way to grow energy. A larger quantity of net energy production could be achieved by eliminating the use of fossil fuel derived fertilizers and pesticides and replacing them with low energy alternatives. The exciting thing about bio-fuel production is that it will point out just how much energy we are wasting on our agricultural process. This will hopefully lead the way towards the development of new low-energy farming techniques for both energy and agricultural production.
Please do your part to help develop the bio-fuel industry and encourage low energy farming techniques. The best way to make a difference in our culture is to vote with your dollar. Every day you make hundreds of consumer choices which shape the economy and world around you. Stop buying fossil fuels and start buying bio-fuels. Take money out of a system that you do not support and put that money into the development of one that you do support. The easiest way to do this in the northwest is by burning biodiesel. Biodiesel is available in over 30 retail locations in King County and it is a non hazardous material so it can be delivered and stored in your garage. Biodiesel is a direct substitute for diesel fuel so you do not need to worry about not finding a fueling station. You can freely mix biodiesel and conventional diesel inside your fuel tank with no consequences.
Just like when you buy organic food you will pay more when you purchase bio-fuel -- normally a 5-30 cents more per gallon. You will also need to own a car with a diesel engine. While the fuel costs more, most people will actually end up saving money when they switch to biodiesel. This is because the diesel engine is about 30% more efficient than a gasoline engine. A normal 20 mpg sedan running on gasoline costs 13 cents per mile for fuel. Compare that to a VW Jetta TDI running on biodiesel. The Jetta gets 42 mpg and only cost 8 cents per mile. By switching cars you end up burning half as much fuel, and saving 5 cents per mile in fuel cost. You also get to say that you run your car on a renewable energy source and have reduced your impact on global warming by 80-90%.

Some Washblog questions Low energy farming How do we move toward what Greg Rock calls for: "eliminating the use of fossil fuel derived fertilizers and pesticides and replacing them with low energy alternatives."? Where does WSU's TripleBio program fit in with this goal?
What crops or products will Bioethanol and biodiesel come from?Are wheat straw and other woody sources the future for ethanol? How about biodiesel? From Harvesting Clean Energy: "Today's starch-based ethanol industry (corn, primarily: N.M.) is a transition phase to a much larger industry based on cellulose, the stuff of which most of the plant world is made. The future industry will be fed by cellulosic materials including agricultural, forest and mill residue, urban wood and yard waste and fast-growing energy crops..."
How about (algea)
How much biofuel can we produce?William Kemp, in his 2006 book, Biodiesel Basics and Beyond, states: "Attempting to meet the rising demand for fossil fuel by replacing it with biofuel is impossible... The key is to combine lower and more efficient energy consumption with biofuel production that has long-term sustainability as the central focus."
The Harvesting Clean Energy site states: "The Northwest has significant potential for bioethanol production. A study by the WSU Energy Extension Program found Washington feedstocks could provide up to 1.2 billion gallons per year (BGY) of ethanol. When economic and environmental constraints are considered, the figure is more like 200 MGY."
The 25 by '25 Work Group, a national alliance of organizations representing farmers, ranchers, and forest owners (co-chaired by a WA farmer, J. Read Smith), envisions: 'By 2025, America's working lands will provide 25% of the total energy consumed in the United States while continuing to produce abundant, safe and affordable food, feed, fiber and fuel.' Where is fuel in this equation?
A new public power movement? What are the prospects for a new public power movement, such as that led by farmers and urban allies in the late 1800s to establish Public Utility Districts? To what extent can something like this happen with alternative fuels?
Patrick Mazza of Climate Solutions comments on the unifying potential of the public demand for sustainable fuels: "For constituencies often at odds, rural communities with economies based on natural resources, and environmentalists centered in metropolitan areas, ethanol development represents a common interest and the prospect for a powerful political coalition capable of moving legislatures."
Democratic energy Democratic energy is defined by The Institute for Local Self Reliance as: "technologies and ownership forms and systems that decentralize power and energy production and energy policy decisionmaking."
Local crops, local economy What are our next steps to grow our alternative fuel crops here in Washington - at least to supply the amount needed under the minimum alternative fuel standard?
