My fellow olds will recall that, back in the 2000s, biofuels were an extremely big deal in the clean-energy world, one of a tiny handful of decarbonization solutions that seemed viable. Biofuels — and the many advanced versions thereof allegedly on the horizon — dominated discussions of climate change policy.Much has changed since then. Principally, it has become clear that electrification is the cheapest path to decarbonization for most sectors, including the transportation sector. The Biden administration has explicitly put electrification at the center of its transportation decarbonization strategy.Biofuels, in the meantime, have gone exactly nowhere. Advanced biofuels remain almost entirely notional, old-fashioned corn ethanol remains as wasteful as ever, and new scientific evidence suggests that the carbon costs of biofuels are much larger than previously appreciated.It's not clear if anyone has told the EPA. For the first time in 15 years, the agency is on the verge of updating biofuels production mandates first established by the Energy Independence and Security Act of 2007, and its proposed standards do not appear cognizant of these recent developments, or of the administration's larger transportation strategy.To discuss the latest developments in biofuels and the EPA's puzzling blind spot, I talked to Dan Lashof, director of the World Resources Institute. We discussed how biofuels have developed since the early 2000s, the lack of progress in advanced biofuels, and the stakes of EPA's coming decisions. Get full access to Volts at www.volts.wtf/subscribe
