The idealized target here is to get off of gasoline entirely for transport, preserving US oil production for things like chemical feedstocks.

But the point translates directly: while biofuels will not be available sustainably at volumes that will allow a plug and play replacement for current oil consumption in transport, shifting those urban and suburban transport tasks that can be entirely electrified on a mix of electric mass transit, regional trains, light rail, trolleybuses, and neighborhood electric vehicles implies that the actual intrinsic need in many rural areas for ranges best provided by high concentration combustion fuels can indeed by provided by things like liquid biofuels, biogas, or sustainable generated ammonia.


I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
