Mowing grass surfaces is the most energy-consuming activity in the maintenance of golf courses, contributing to GHG emissions. Additionally, as a result of the need to maintain the height of the turf at an appropriate level, a significant amount of biomass residues is generated, which requires proper disposal. The goal of this work concerns the determination of biomass residues resources (grass clippings), obtained after mowing of the six selected golf courses in Poland. Based on own research, the selected golf course was characterized in terms of the area, frequency of mowing as well as management strategy and disposal of mowing residues. Based on the indicators obtained from the literature review, the biomass potential was determined, which was equal to 77.96 MgDM∙year^-1 (± 5.51 MgDM∙year^-1) to 150.97 MgDM∙year^-1 (± 6.25 MgDM∙year^-1) depending on the golf course. The obtained results and performed calculations indicated that the existing resources allow for the construction of microbiogas plants, fed by grass clippings with the electric power of 9.56 kW to 18.51 kW, which would allow for the production of electricity in the amount of 76.19 MWh∙year^-1 to 147.55 MWh∙year^-1 and heat in the amount of 237.36 GJ∙year^-1 - 459.67 GJ∙year^-1. In addition, it was shown that the production of electricity and heat exceeds the energy input for mowing golf courses, making a positive energy balance of the process.
