The paper presents results of studies on energy efficiency of production of some Brassica oilseed crops: winter and spring oilseed rape (Brassica napus L.), white mustard (Sinabis alba L.), Indian mustard (Brassica juncea L.), spring false flax (Camelina sativa L.) and crambe (Crambe abyssinica Hochst.), which in the international commercial trade are referred to as oilseed rape. In the agronomic and ecological conditions of Poland, 1 ha of winter oilseed rape can generate over 166 GJ energy, including about 45 GJ of energy utilisable for production of methyl (ethyl) esters. Having subtracted the crop production input (about 21 GJ·ha-1), the cumulated energy gain from 1 ha winter oilseed rape is energy equivalent to nearly 3.5 t of diesel oil or 8.5 t of firewood. The energy potential of spring oilseed crops seeds and straw is relatively lower: 31-39% less for spring oilseed rape and white mustard, 51-53% less for false flax and Indian mu
