What's going on with biofuels?
In this episode, Dan Lashof of the World Resources Institute discusses the trajectory of biofuels since the early 2000s and the implications of new biofuel standards recently proposed by the US EPA.

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.
Alright then. Dan Lashof. Welcome to Volts. Thank you so much for coming.

Really happy to be here.

I've been wanting to do an episode on biofuels forever because I often just pause to think, whatever happened to biofuels? Because old people like you and I will recall way back in the day, in the early times, biofuels used to be a very big deal. They used to be the top line item, the sort of the hot subject of conversation, and it's really flipped since then. So maybe just to start, let's use our little time machine squiggly squiggly fingers, time machine, go back to say 2005 to 2010, the early 2000s, and just sort of tell us what was the state of the decarbonization conversation then and what role did biofuels play in it?
Dan Lashof
Right, well, back then, Tesla hadn't built its first car. Photovoltaics cost ten times or more what they do today. And the big fight was to prevent hundreds of new coal plants from being built. So the idea that we would replace gasoline with electricity seemed far-fetched at best. And a lot of environmental advocates were focused on fighting coal. There was some discussion of alternative fuels, but when you looked at the transportation sector, biofuels seemed like one of the best options out there. And then there was this idea, there was a debate about corn ethanol from the beginning, right?
David Roberts
Corn ethanol goes back. I mean, I kind of want to distinguish between corn ethanol and kind of biofuels. The larger category, like corn ethanol, goes back farther than the rest of this stuff. Right?
Dan Lashof
Right, but back then we weren't making much of it, right? So in 2007, there was about 6 billion gallons of corn ethanol being produced, which is about 4% of gasoline consumption back then. And there was a debate about it. A lot of that debate was like
