Biofuels are increasingly lumped into a single category of environmentally apocalyptic dead-end solutions. As the food vs. fuel debate rages on, it’s no wonder that the general public believes this.
But not all biofuels are created equal, as the chart above illustrates (click the image to see full size). It’s one of the best depictions I’ve seen of how each biofuel feedstock has completely different impacts on overall greenhouse gas emissions, water and pesticide use, and the energy required to produce the fuel.

This 100% biodiesel-powered, 78 ft wave-piercing trimaran aims to set an around-the-world speed record while maintaining a net zero carbon footprint. The Earthrace left Sagunto, Spain, on April 27, and has already made excellent time across the Atlantic, landing in Panama just 8 days later.
Inspired by the desire to “connect with people about the need to get renewable fuels into our energy mix and to inspire them to do something,” the Earthrace has already generated a whirlwind of publicity. Much of this is due to the boat’s eco-technological appeal. It’s been described as “a rally car but for oceans”, with the ability to submerge up to 23 feet underwater while powering through the ocean. The “eco-” part doesn’t just include circling the globe on 100% biodiesel. Parts of the boat are made from a hemp-based composite, bedding foams are made from canola oil, and the operation’s total carbon footprint has been balanced by purchasing carbon credits.
I happened across this video on algae biofuel today: a company I’ve never heard of, Valcent Products, claims they can grow algae to produce oil yields of 100,000 gallons per acre. That’s the upper range of estimates I’ve seen for algae production—an absolutely phenomenal amount of oil—which Valcent attributes to their ‘high density vertical bioreactor’ system. Check it out (more video after the jump):

Alan Doering of AURI says agricultural residues and co-products aren’t waste, they’re potential new revenue streams to power the future.
AURI, or Agricultural Utilization Research Institute of Waseca, Minnesota, is a nonprofit organization that develops new uses for agricultural products and ag-processing co-products.
Alan Doering, an Associate Scientist with AURI, filled me in on steps being taken to utilize every bit of what used to be considered products of the waste stream.

It looks like Solazyme will be making algal biodiesel for the US military, after a test-drive demonstrated the fuel’s superior cold-weather properties when compared to commercially-available biodiesel.
Former Director of Central Intelligence and Under-Secretary of the Navy R. James Woolsey tested the fuel himself by driving to the Worldwide Energy Conference & Trade Show in an unmodified 2008 Ford F450 fueled by 100% algal biodiesel.
Despite intense debate surrounding the growing global food crises, the European Union today defended expanding the use of biofuels in all 27 member countries. Part of the EU’s climate change package, the current proposal sets a target of meeting 10% of transportation fuel with biofuels by 2020.
As I reported last week, Europe’s EPA advised suspending the EU’s biofuel targets until a comprehensive environmental analysis could be completed. Barbara Helfferich, spokeswoman for EU Environment Commissioner Stavros Dimas, said no way is that going to happen:
“You can’t change a political objective without risking a debate on all the other objectives,” meaning that changing biofuels targets could lead to questioning the entire climate change package.
Adding to the ongoing discussion about biofuels affecting worldwide food prices (see Biodiesel Is Raising Food Prices), NPR’s Morning Addition briefly interviewed World Bank President Robert Zoellick last Friday.
Zoellick called it a “perfect storm of things coming together…” and listed 7 different issues contributing to the increasing cost of food, which led to rioting in Haiti and Egypt last week, along with a general strike in Burkina Faso:
Increased world demand for grains and vegetable oils due to population growth (esp. in China and India), the weak dollar, agricultural production problems around the world, and $100/barrel oil are some of the driving factors accounting for increasing food prices.
After covering 22 of the most popular myths about biodiesel, I realized I’d only given lip service to a major issue: increasing food prices. In Myth #2, I mentioned that the goal of biodiesel production is to move away from food-based feedstocks.
But until that happens, the question remains: if I use biodiesel made from soybeans right now, am I contributing to the larger problem of increasing commodity prices and starving poor people?
Most of us are at least vaguely familiar with biodiesel, but how much do we really know?
While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.
It’s been exactly one year since I published the first Biodiesel Mythbuster on GreenOptions.com, and its popularity made a sequel inevitable. By way of a short introduction, here’s what I wrote last year:
