AbstractThe objective of the paper was to determine the energy efficiency of biomass production from Sida hermaphrodita and miscanthus in the selected farm. The paper covered research for the real residential building. Calculation of energy consumption of biomass production were made for theoretical plantations with the surface area of 1.20 and 1.30 ha. Energy needed for biomass production from Sida hermaphrodita is 27 606.1 MJ ha−1, while for the miscanthus it is 30 198.9 MJ ha−1. In the structure of energy consumption of production the highest share is in case of materials and raw materials (37.6% for Sida hermaphrodita and 32.8%—miscanthus), energy carriers (31.5% and 32.8%) and then investment means (17.2% and 20.9%) and human labour (13.7% and 13.4%). In case of Sida hermaphrodita, energy efficiency of biomass production from the acreage of 1.20 ha is 6.5, namely, more than six times more energy will be obtained in the first year of biomass production from Sida hermaphrodita than energy incurred on setting up the plantation. In case of miscanthus, for the surface area of cultivation of 1.30 ha the estimated index is 5.6.
