biodiesel

Biodiesel is one of the most intriguing of those new possibilities...crops of soybeans and rapeseed and maybe even algae, grown by present day farmers, processed into a diesel fuel substitute that works just fine in modern Volkswagons and Mack trucks and school buses--even in the oil-burning furnace down in the basement. It is potentially a truely sweet solution, offering a new market for hard-pressed local farmers even as it begins to help solve some of our most pressing environmental problems. Greg Pahl's book...manages to raise the right questions (and raise them early enough) so that we can perhaps build a structure for this developing industry that serves local farmers and processors instead of simply corporate agribusiness giants.

Biodiesel has been getting a bad name because of the potential for competition with food production. It has always struck me that some of the loudest voices criticizing biodiesel has come from the oil, coal and nuke lobbies. But it did seem like competition with food production may be a critical problem with biodiesel.

I have been thinking about biofuels recently. I think it has been on my mind thanks to a recent car rental experience Joy and I had in California, and thanks to a proposal my City Councilman is making that would over time require all heating oil in New York City to be B20 biodiesel.

Biofuels are in one way the easiest alternative to oil-based fuels for transportation and heating purposes. This is because, depending on the biofuel, it requires the least change in our infrastructure and the manufacturing process of our cars and heating systems. For example, up to B20 biodiesel, any diesel car or boiler system can run on a biodiesel/traditional mix with no modification. The modifications to use B100 biodiesel are relatively minor and could be incorporated over time. My understanding is that ethanol based fuels also can be used in mixtures with traditional fuels with no modification, and only minor modifications are needed for pure biofuel. So, in terms of conversion to a new fuel, biofuels are the easiest compared with, for example, electric or hydrogen cars.

There is one major problem with biofuels. There are, depending on where the raw materials come from, limitations on just how much biofuel can be produced without competing with food production, thus driving up food prices and reducing availability, or leading to deforestation. So the challenge is to find sources of raw materials for biofuels that are plentiful AND don't compete with food production or preservation of forests.

Joy, Jacob and I travelled to California in December to visit my family. Even after 10 years in NYC, I still miss living in California. I am so much more relaxed and happy in California. Sure, NYC is more exciting and it is far easier to get around without a car in NYC, which I greatly appreciate. But Los Angeles is still my favorite city to live in, with the possible exception of Kyoto which was WONDERFUL to live in as well.

Got a lot to blog about that trip, including some restaurant reviews. But first I want to blog about car rentals. Joy and I don't own a car, but we rent whenever we need a car. Whenever we can, we rent a green alternative kind of car. Which means slowly we are gaining personal experience with several kinds of car rentals in Los Angeles...and many options are available elsewhere.

We are willing to spend somewhat extra for a green car, particularly since you save money on gas. But sometimes the difference in cost is too much, so we just rent a regular car with good gas milage. But I always feel better when we can rent an actual green car.

This last trip we rented a biodiesel through a company based in Hawaii that specializes in biodiesal Volkswagen rentals. The company is called bio-beetle. We rented a Jetta, not the eponymous bio-Beetle. Jacob loved calling our car "The Bio-Jetta," and would greet it every time we got in, "Hi Bio-Jetta!"
