Current energy policy at European level is overall favourably inclined towards the spread of renewable energy sources. Promoting them is a priority linked primarily to environmental commitments and assured continuity of supplies, as these figure among the main objectives of energy policy at present. One of the strategic key-sectors in the campaign to launch renewable energy sources promoted by the European commission (SEC (99) 504, 14/04/99 Campaign for take-off - CTO), specifically concerns the realization of large scale projects to exploit biomass more widely. Dedicated energy crops are of special importance in biomass exploitation. They are, however, still little used because their cost is not competitive compared to traditional fuels. This paper provides an outline of the true potential productive capacity of this resource and identifies the factors regarding technical and economic feasibility.
