Venezuelan leader Hugo Chavez, together with former Cuban leader Fidel Castro, launched a series of article criticizing the biofuel industry.These series of articles came in after US President George Bush supported the ethanol movement of Brazil. Before this, both Chavez and Castro were staunch supporters of the biofuel industry.
Well, we know what happened next. Cuba started to produce ethanol-based fuel, striking up deals with Venezuela in the process. So was it really hate for biofuels or hate for the United States? Your guess is as good as mine.
