Aim of this study was an analysis and assessment of the economy and energy effectiveness of winter wheat and winter rape cultivation for liquid biofuel production. The cost of production and economical effect index is more profitable in case of winter rape. Also the final balance of energy effectiveness has shown better values if the biodiesel had been produced from winter rape as compared with bioethanol from winter wheat. Calculation of the obtained products and their comparison with an energy unit has shown that the netto energy from biodiesel was positive while that from bioethanol was negative, which means that in the latter case expenditure is greater than that gained in the produced biofuel.
