The former draws the wrong lessons from the latter

The Mustache of Understanding brings us another variant of the Brazil is awesome! story, and commits the standard two errors:

1. He conflates corn-based and cellulosic ethanol, failing to note that Brazil uses the latter and we the former.
2. He makes no mention of the fact that Brazil’s per-capita energy use is about an eighth of ours (1,064 vs. 7,921 kgoe per-person-per-year, as of 2001).

These facts are relevant to an assessment of Brazil’s success with biofuels, no?
