The BRIC countries will use more energy than the developed countries by 2030. Belgium tries to prepare for the future with ridiculous projects like the biodiesel plant in Gent. Everyone knows by know that biodiesel from poppyseed oil is energy negative. Why else would biodiesel in Europe and the US be more expensive than petrol? The US is subsidizing biodiesel production with billions of dollars. Flexengines became a success in Brazil because 'alcool' at the pump is cheaper than 'gasolina'; as simpel as that. No way Europe or the US will be able to compete with the ethanol of Brazil.
Brazil already discovered the force -and challenges- of hydro (nearly all its electricity is coming from hydro), but the true unlocked potential in South Africa and Brazil is solar !
