So why are so many voices raised against biofuels? Salgado said that it's because big oil companies are threatened by the expansion of biofuels. According to him, ethanol - which is already at five percent of the market in the U.S. - is taking sales away from gasoline. This can only make big oil companies angry and do "whatever they can" to avoid the expansion of biofuels in order to keep their market share. Speaking about Spain, where Abengoa Bioenergy is based, Salgado stated that the country has no more ethanol fuel pumps because most gas stations belong to big oil companies. There, that should get people talking.
