Sugarcane ethanol obviously is a better conversion than corn. Besides sugarcane grows like a weed in Brazil.
They have been wanting to export sugarcane ethanol to us, but US corn growers block it.
“US corn growers block it.”
It’s the big ethanol producers like Archer Daniels Midland (ADM) that are the blockers. Ask the livestock producers how happy they are about the use of corn for fuel.
The US has imported sugarcane based ethanol for quite some time.

However, the US production of Ethanol has grown to be so large that this import amount is nearly insignificant.

Ethanol Production Stalls in Brazil

Brazil experienced a biofuel boom in March 2007, topping out at second in world output behind the USA. The fermentation of sugars produced motor fuel that lowered carbon dioxide emissions, and Brazil became a model for how it was possible to stop relying on fossil fuels.
Five years later, biofuels have been criticized and critics charge that devoting millions of hectares of agricultural land to fuel crops is driving up food prices and the climate benefits of biofuels are modest. The policies of the Brazilian government have compounded the effects of the global economic downturn.
The domestic consumption of liquid ethanol in 2012 has been 26% lower than for the same period in 2008 and forty-one of Brazils roughly 400 sugar cane ethanol plants have closed during that span. The price of pure ethanol is so high that in most states its cheaper to fill up with petrol blends that contain 20% ethanol. The shift back to fossil fuels, combined with the rapid growth in the number of cars on Brazils roads, has worsened smog and caused emissions in the transport sector to spike.
Brazils ethanol experience is an example of what can happen when climate and energy planning clash with economic decision-making. Problems began with the 2008 economic crisis, which stalled new investments in the sector just as it was expanding rapidly. The industry fell back on harvesting cane from older, less productive sites instead of developing new plantations. Average yields plummeted from 115 tonnes per hectare in 2008 to 69 tonnes in 2012. This has forced Brazil to import 1.5 billion liters of maize ethanol from the USA in the last 2 years.
