Making biofuel, it sounds like a complicated process taking place in a laboratory somewhere, but in reality it’s quite simple and happening in small, rural Vermont farms. Vermont farmers like John Williamson of State Line Farm and others are electing to create their own fuel and meal. These farmers are enjoying the benefits of the distance to source resiliency and cost reliability that comes with the local production for local use biofuel model they have adopted.
As John Williamson, a Vermont Bioenergy grant recipient says, “100 years ago everyone produced their own fuel; we are just doing that now in a different way.” This is a novel way to look at what he is doing on his North Bennington farm. Vermont farmers in the past would plan to allocate their acreage to feed their livestock, some of which aided in energy-intensive farm activities like plowing, planting, and the eventual harvesting of their field. With the local production for local use model, John is now thinking about how to feed his tractor so he can do the same activities. So what is the feed of choice for John’s John Deer tractor? Sunflowers!
John loads dry and clean sunflower seeds into hoppers on a TabyPressen Oilpress, where screw augers push the seed through a narrow dye. Extracted oil oozes from the side of the barrel and is collected in settling tanks while pelletized meal is pushed through the dye at the front and is stored in one-ton agricultural sacks. The first of the two byproducts, the seed meal, can fuel pellet stoves, serve as fertilizer for crops, or find its way to local Vermont farms to supplement animal nutrition as livestock feed. The second byproduct, the fuel, could at this point be used as culinary oil for cooking, but instead will experience further refinement and become biofuel.
The processing of the oil takes place in Johns self-designed Biobarn. In the below video, John Williamson and Chris Callahan of University of Vermont Extension show us how they can grow oil crops, make biodiesel, feed animals, and save money!
Vermont’s solar industry is lauding Governor Peter Shumlin’s proclamation of the third Saturday in June as “Celebrate Solar Day” in Vermont.
The solar proclamation, announced at the Whitcomb Farm in Essex, coincides with this June 20th, when solar projects in communities throughout Vermont will be open for public tours. June 20 is the weekend of the Summer Solstice.
Like open sugarhouse weekend in the spring and open art studio weekend in the fall, the inaugural summertime tours will give Vermonters the opportunity to get an up-close view of solar systems to learn about the technology, solar economics, and the benefits of solar to our community. Solar customers, host farmers, and owners will be on-hand to speak with the public.
More than 50 systems across all regions of the state will be participating in Celebrate Solar Tours and a map of open tours can be found here. Many participating sites will host refreshments, music, or other entertainment. Other planned solar events include community walking tours of residential solar installations, miniature golf, a self-guided bike tour, and on-site yoga.
The Governor’s proclamation notes that “solar energy represented 99% of new electrical capacity in the state in 2014 and more than 5,000 Vermont customers have installed solar” through Vermont’s net metering program.
Further, it cites that the Vermont clean energy industries employ over 15,000 Vermonters, with solar providing “a broad spectrum of employment opportunities, helping retain and attract Vermonters working in manufacturing, installation, and sales, among other careers.”
The Whitcomb family is host to a 2.2 Megawatt solar farm that provides energy for Vermont’s SPEED program.
Among the solar sites open to tour June 20: iconic and sweet Vermont attractions like Cold Hollow Cider and Morse Farm Maple Sugarworks, high-tech attractions like Draker and Small Dog Electronics, agricultural farms like Champlain Orchards, shared community solar arrays, and some of Vermont’s highest producing solar farms.
At the announcement of the solar tours, Paul Brown, owner of Cold Hollow Cider in Waterbury Center, which has a 150kW system powering its operations, said of the event, “Folks know us and visit us for our cider and donuts. But we are thrilled to open up the field behind our cidery to share the benefits of solar technology to our business and our community. We’ll of course also be serving up some sweet treats for those who come by.”
The first annual Celebrate Solar Tours on June 20 will feature public tours of more than 50 solar systems of varying size throughout the state. The public will have the opportunity to get an up-close understanding of the technology, economics and benefits to the community. Open systems will be designated with roadway signage and many will feature music, refreshments or other entertainment.

In 2008, the Vermont Bioenergy Initiative began to explore the potential for grasses energy grown in Vermont to meet a portion of the state’s heating demand and reduce the consumption of non-renewable fossil fuels. The Grass Energy in Vermont and the Northeast report was initiated by the Vermont Sustainable Jobs Fund, and carried out by its program the Vermont Bioenergy Initiative, to aid in strategic planning for future grass energy program directives.
Grass Energy in Vermont and the Northeast summarizes current research on the agronomy and usage potential of grass as a biofuel, and points to next steps for the region to fully commercialize this opportunity. The keys to commercializing grass for energy are improving fuel supply with high-yielding crops, establishing best practices for production and use, developing appropriate, high-efficiency combustion technology, and building markets for grass fuel.
Perennial grasses, while serving as a biomass feedstock for heating fuel, also have numerous other benefits to farmers. The grass energy benefits reviewed in the report include retaining energy dollars in the local community, reducing greenhouse gas emissions from heating systems, improving energy security, providing a use for marginal farmland, and reducing pollution in soil and run-off from farms.
Regional and closed loop processing were two models recommended by the report, both involving farmers growing and harvesting grass, but differing in where the grass is processed into fuel and where it is used. The regional processing model calls for aggregating grass from a 50-mile radius at a central processing facility, where the grass is made into and used as fuel, or sold to local users. The closed loop model suggests farmers growing and processing grass on-site for on-farm or community use. Other models, like mobile on-farm processing and processing fuel for the consumer pellet market have significant hurdles to overcome if they are to be successful in Vermont.
In the below video a Vermont agronomist explains switchgrass production followed by entrepreneurs turning bales of grass into briquette fuel. This grass biofuel feedstock can be grown alongside food production on marginal agricultural lands and abandoned pastures, and in conserved open spaces. The harvested grass can be baled and used as-is in straw bale combustion systems, or it can be compressed into several useable forms for pellet fuel combustion systems.
For more information on grass biofuel feedstocks and to read the full Grass Energy in Vermont and the Northeast report visit the grass energy section of the Vermont Bioenergy website.
In order to meet the goals set by Vermont’s comprehensive energy plan for Vermont to produce 90 percent of the state’s energy needs from renewables by 2050 and reduce Vermont’s greenhouse gas emissions by 50 percent from a 1990 baseline, Vermont farmers will have an important role to play. As Vermont experiences growth in food-related businesses and jobs, decisions about energy become more important prompting statewide energy and agriculture collaborations. In the following episodes of Across the Fence, UVM Extension agricultural engineer and Vermont Bioenergy Initiative biofuels consultant, Chris Callahan, shares two stories about Vermont farmers who are rethinking their on-farm energy. In both examples UVM extension is able to work with the farmers to help make cleaner, renewable on-farm energy sources a practical solution that saves money and results in greenhouse gas reductions.

The Vermont Bioenergy Initiative aims to connect diversified agriculture and local renewable energy production for on-farm and community use by supporting research, technical assistance, and infrastructure development in emerging areas of bioenergy including biodiesel production and distribution. As we move into the growing season, there are a variety of pests that can potentially affect sunflower, canola, and soybean biomass feedstock production. In this video a University of Vermont agronomist explains how to control theses potential biomass feedstock pests and increase crop, and eventually biofuel, yields without heavy reliance on pesticides and herbicides.
Coming this fall the University of Vermont will be offering a bioenergy course taught by Anju Dahiya, cofounder of General Systems Research, LLC, lead biofuels instructor at the University of Vermont’s Rubenstein School of Environment and Natural Resources, and Vermont Bioenergy algae for biofuel grant recipient. This course is open to both degree and non-degree students from any background or department, as well as farmers, entrepreneurs, and teachers interested in developing curriculum, or projects at school or college levels. This course is also approved for graduate credit.
Potential participants are offered the option of variable credits, ranging from 0 to 6 credit hours. This allows prospective students to only attend lectures and have access to online course materials for 2 credits; further their experience with the addition of hands-on labs and field trips for 3 credits; or participate in all aspects of the class while additionally applying lessons to a service learning project with a community partner, earning 4 credits. Participants have the ability to add up to 2 more credits, totaling no more than 6, for additional work with the community partner pending special permission from the course instructor.
Lectures will be held twice a week between September 18th and December 9th of 2015. Friday lectures will be on campus from 4:05 pm to 7:05 pm, followed by Saturday morning field trips between 10:00 am and 1:00 pm for those students who elected for 3 credits or more. The course required textbook, Bioenergy: Biomass to Biofuels, was edited by Anju Dahiya less than a year ago and represents a compilation of work from an extensive list of well-respected university extension programs, such as The University of Vermont Research Extension, as well as numerous national organizations including the US Department of Energy’s National Renewable Energy Laboratories.
The Energy Action Network (EAN) is a community of a community of Green Mountain State stakeholders working to change the Vermont energy landscape “to end Vermont’s reliance on fossil fuels and to create clean, affordable energy and secure electric, heating, and transportation systems for the 21st century.” Their goals are consistent with the State of Vermont 2011 Comprehensive Energy Plan, which aims to meet 90% of Vermont’s energy needs through efficiency and renewable sources by 2050.
EAN has identified a series of pathways for Vermont for Vermont to accomplish the paradigm shift of 90% renewables by 2050. Membership is structured into working groups focused on four “leverage points” capital mobilization, public engagement, technology innovation, and regulatory reform. Current projects include alterations to Act 250, changes in zoning laws, programs to promote bringing rental properties into efficiency standards, and assessing current land use for its potential for bioenergy and solar projects.
One notable awareness vehicle, Brighter Vermont, encourages Vermonters to change the way common energy use and think more about where energy comes from. Read more about how Brighter Vermont helps change energy behavior. EAN also works with municipalities and recently helped Montpelier plan for a 15 year track to become the first state capital to accomplish all of its energy needs with renewable energy. On February 12, 2015 the Montpelier City council accepted and endorsed the plan to make Montpelier a “net zero” city.
Currently, EAN is working with the Vermont Sustainable Jobs Fund to expand the Vermont Energy Atlas website into the Community Energy Dashboard. The Dashboard will enable communities to understand their energy use and make clean energy choices and investments across all energy sectors—heating, transportation, and electricity. The Dashboard will make energy use visible and understandable to consumers and communities by showing town-level progress toward Vermont’s 90% renewables by 2050 goal. The Dashboard will also shows existing and potential renewable energy sites (solar, wind, hydro, biomass). We will provide updates as they develop. Stay tuned into the Vermont Bioenergy Field Notes blog and visit the Energy Action Network website to learn more.

The State of Vermont 2011 Comprehensive Energy Plan calls for 90% of Vermont energy needs to be met through efficiency and renewable sources by 2050. As Vermont residents witness continued high numbers in clean energy jobs, and advanced renewable energy legislation they will also need to take responsibility for Vermont to meet these goals, as every Vermonter will need to contribute in some way for Vermont to meet this ambitious goal. Enter Brighter Vermont, an action oriented program of the Energy Action Network, to help everyday Vermonters rethink where their energy comes from, how they use it in their daily lives, and what they can do to help the state reach its 90% by 2050 goal.
The Brighter Vermont website is packed with testimonials and videos shared by individuals who describe the financial decisions they are making to positively affect the environment, Vermont’s economy, and their wallets. A family in Rutland reports on small home improvement they have made to keep out the Northeast cold out and share a video about lowering energy costs, with the help of Green Mountain Power, by properly weatherizing their home, changing to energy efficient LED bulbs, electing for a heat pump, and adding solar panels. The overall transition has made them a more energy conscious family and was achievable with a ten year loan the family is pleased to see being offset by reduction in energy costs.
A family in Burlington’s journey towards reducing their carbon footprint is documented in a fun testimonial video where the family picks out their first electric vehicle. They were able to replace one of their family vehicles with a zero emission Nissan Leaf (hyperlink to video) that was available with an affordable two year lease. The switch from a classic Vermont staple vehicle, a Subaru, to the Leaf, has helped the family not only save money at the gas pump, but the, as the family reports, electricity used to charge the vehicle comes from renewable energy. They enjoy educating their friends and neighbors about this carbon footprint transition.
Brighter Vermont also hosts ways for businesses, schools, and towns to become more efficient and promote renewables in their community. Methods for how schools and businesses have become more efficient by transitioning to modern wood heating. A featured video produced by VEIC (hyperlink) features 54 schools from across Vermont currently heating with wood chips and pellets which provides heat for nearly one third of k-12 students across Vermont. Our own Vermont Bioenergy Initiative Vermont on-farm energy videos are also featured for farmers to learn more about the emerging areas of oilseed, grass, and algae biofuel.
There is much that needs to be done in the fight against climate change and moving Vermont away from its reliance on fossil fuels. While this road can be daunting, it is important to remember that we can all make small changes that will benefit us, our community, and our state. And the Brighter Vermont website provides a fun and interactive platform for individuals, families, businesses, and institutions to learn how to contribute and share these efforts with others so Vermont can take steps towards meeting our renewable energy goals for our future.
Vermont Technical College is committed to educating students as the workforce to support renewable energy systems and infrastructure development in Vermont.
