Last month the Wall Street Journal accused me of advocating subsidies for food-based ethanol. I ought to “take a vow of embarrassed silence,” it said, for claiming that ethanol’s contribution to the food crisis is “overblown.” The Journal’s claims would be laughable if the stakes were not so high.
Cellulosic biofuels offer a chance to have an environmentally meaningful impact on petroleum use while benefiting farmers, entrepreneurs and consumers. I have many investments in biofuels companies. Some say I believe in biofuels because I have invested in them. The truth is that I invest in biofuels because I believe they can help our environment, economy and national security.
Just as the word “drug” can refer to aspirin or cocaine, “biofuel” refers to a variety of products that vary dramatically in their environmental impact and effects on food prices. For instance, biodiesel from food oils such as soybean or palm oil has traditionally created environmental negatives. But corn ethanol has been a stepping stone to cellulosic ethanol, a preferred alternative that is likely to achieve unsubsidized market competitiveness with oil within a few years.
