The subject of biodiesel came up last week, and in explaining the concept to my daughter I remembered how much I’m drawn to it—as opposed to electric cars, which I instinctively distrust. That statement says as much about me as it does about the two technologies, so let me unpack it a little.
Here’s why I’m drawn to biodiesel:
1. Biodiesel piggybacks on existing technology. We already know how to build and maintain diesel engines.
2. At its best, biodiesel turns waste material—used vegetable oils—into fuel rather than requiring new production.
3. You can literally make biodiesel in your back yard. More practically, it can be made on a community scale.
Will biodiesel solve all the world’s problems? No. It is a small and partial solution to an enormous global problem, which though it cannot solve the whole, nevertheless—by virtue of being small!—empowers people to roll up their sleeves and get to work. Moreover, in principle, it creates no new problems that others will have to solve later, e.g. waste that will have to be cleaned up.
