Oil Companies and Bio-Fuels

South America is trying to demonized non government owned oil companies. Yet at the same time, the same countries that demonize foreign companies wonder why no one will invest in their countries. As one Spanish banker says:

``It makes no sense doing business outside the First World. What you earn in a decade, you lose in a week when an unscrupulous president changes the rules of the game.''

Bio-Diesel is good, but like all fuels is not a perfect replacement. Apparently it doesn't work well in the cold and passengers on bus lines stop caring about how green the company is if the buses don't work at -15 degrees.
