Although the time span of this research was limited, the report gives an overview of the sector and lists a number of issues that the sector is faced with. The bio-energy sector is a relatively young but rapidly growing sector. It is a diverse sector as there is a large variety of types of feedstock, production methods and uses. While bio-energy crops are produced and used worldwide there are clear differences between different regions. Ethanol seems to be the most popular type in the Americas, while Europe focuses more on biodiesel and electricity generated from biomass. At the moment trade in biomass is still limited, and most bio-energy is produced locally. Due to the rapid developments in this sector, research on the market and its critical issues will quickly be outdated. For a good overview of the sector, research therefore needs to be kept up to date and often renewed.
