1.0 Abstract

This study is about biofuel and how it can be used as an alternative resource of energy. Biofuel can be produced from two resources; the first generation of biofuel is produced from corn and Indian corn and the second generation is produced from waste products from the agriculture. When the first generation of biofuel is produced, different enzymes break down the long and complicated starch- and sucker molecules, into glucose which can be converted to ethanol. Second generation biofuel uses the same method, but in second generation it is more compact and stronger molecules which has to be converted, and therefore it takes time to produce biofuel from second generation. First generation is the most effective way of producing ethanol, but this process needs eatable plants and vegetables. This can make the prices on food raise dramatically, which can result in hunger in the third world. In this study there will be looked upon a solution, if there could be used seaweed instead of corn there would not be the same problems socially. This is because seaweed is not the main source of food in the third world. The study will also make a policy analyze of the Danish policy and give a short account upon the problems of making a global climate change agreement. The study will end up in a discussion of why seaweed could be a good solution to an alternative energy resource.
