<p>Second generation biofuel production systems are significantly better than the first generation systems. However, the size of areas on which the energy crops are grown depends on the public support and it decreases if the public support is missing. Despite all the environmental and economic benefits, perennial bioenergy crops do not currently play a significant role in the EU. The market for bioenergy biomass has yet to be developed. It is believed that the basic limiting factor for the development of biofuel crops in the EU will be available land areas. On the other hand, in Southeast Europe there is great untapped potential for biomass and bioenergy production in abandoned and marginal agricultural areas. Crucial factor in in accepting new crops, such as bioenergy crops, is their profitability compared to already existing crop systems. At the same time, perennial bioenergy crops are investments that come with the certain risks. Economically viable production of dedicated energy crops will be difficult to achieve on most lands classified into V-VIII land capability class. In terms of risk of farming investments, corn has an advantage over all perennial bioenergy crop systems. As many as 9 types of risk for the successful production of bioenergy crops have been identified: (1) Water supply of the crop; (2) The presence of weeds in the crop; (3) Frost and chilling stress of crops; (4) Crop lodging; (5) Crop diseases; (6) Short harvest times and variable yields; (7) Economic viability of cultivation on land areas of lower land capability class; (8) Influence of agricultural techniques and agro-ecological conditions on biomass quality; and (9) Storage of harvested biomass and fire hazard. The transition to 100% renewable generation in the electricity sector is considered unattainable, at least for now. Therefore, the cultivation of perennial bioenergy crops must</p><p>be systematically planned and further improved.</p>
