When Congress created the Renewable Fuel Standard (RFS) more than a decade ago, lawmakers hoped the federal fuels program would spur development of a domestic biofuels industry that would help reduce oil imports with millions and millions of gallons of home-grown ethanol – with a particular focus on increasing volumes of cellulosic biofuel made from corn stover, wood chips, miscanthus or biogas. By 2022, it was expected that 16 billion gallons of cellulosic biofuel would be produced, but a couple of other things happened instead.
First, the U.S. energy revolution happened. Our crude oil imports fell mostly because of surging domestic oil production, not the RFS. Through safe hydraulic fracturing and horizontal drilling, American output grew from less than 6 million barrels per day to more than 9 million barrels per day – the growth in domestic production more than accounting for the reduction in net imports.
