Substituting biomass for fossil fuels in the generation of energy is an important strategy for the EU in order to mitigate climate change. Fo this purpose bioenergy is being promote through several EU Directives, which aims to increase the use of renewable energy sources to 22% in 2010. Biofuels are also promoted in the Biofuel Transportation Directive which set out to increase the share of  biofuels or other alternative fuels in transportation fuels to 2%by 2005 and 5,75% in 2013. A number of crops have been investigated with regard to their suitability for biomass production in Europe. These analyses show that perennial energy crops such as willow perform much better in terms of energy than annual food crops. In order for the average farmers to adopt a new crop such as willow perform much better in terms of energy that annual crops. Willow production has a high net energy output compared, for example to grain and oil seed production and its biomass yield is relativly high.  Salix hibrid is used in other countries because of their heigh grow for material to product lighters. The productivity of this plantation is about 30-40 tones/hectars, and this plantation we can exploit 20-25 years. This paper offer a solution to develop energy crops in the areas where the forests are not so good represented. The objective of this study was to present the advanteges of growing willow in comparison with traditional crops and also to present an economic perspectiv to cultivate willow for biomass which will be use to product lighters. The economics of growing willow, wheat and barley was analysed on farm level using a model presented by Rosenqvist. This model was developed for analysis of the annual ecomomics of growing willow, aperennial crop comparable tot hat of wheat and berley, which are annual crop. The model employs a total step calculation method in which all disbursements and revenues are discounted.
