The aim of this study was to calculate energy consumption of Finnish domestic farms by source books and compare these results with the actual field energy consumption. Base of this study was on Finnish and foreign research, according to which the energy consumption of domestic farms was calculated. Information about actual energy consumption was taken from enquiry executed by Työtehoseura, which was part of project done by Työtehoseura, University of Jyväskylä and Finnish Ministry of Agriculture and Forestry: Biokaasu maataloudessa. The study composed of dairy, cattle, farrow-growing and feederpig farms. Stanchion barn calculated energy consumption in TE-center areas I-II was between 2523–3734 kWh/cowplace/year (avg. 3129kWh) and real energy consumption was 1987–9000 kWh/cowplace/year (mv.5264 kWh). In the TE-center area III the calculated energy consumption was 2585–3796 kWh/cowplace/year(mv.3191kWh) and the real energy consumption was 1630–5024 kWh/cowplace/year (mv.4566 kWh). Parloe stalls calculated energy consumption in the TE-center areas I-II was 2480–4139 kWh/cowplace/year (mv.3310kWh) and real energy consumption was 2631– 6943 kWh/cowplace/year (mv.4571 kWh). In the TE-center area III calculated energy consumption was 2555–4214 kWh/cowplace/year (mv.3385 kWh) and real energy consumption was 1513–7763 kWh/cowplace/year (avg.5134 kWh). Energy consumption of barns for Calfs from 2 weeks to 6 months in the TE-center areas I-II was 445-652 kWh/calf /year (avg.549 kWh) and real consumption was 390-1263 kWh/calf/year (avg. 774 kWh). in the TE-center area III calculated energy consumption was 541-748 kWh/calf/year (avg.645 kWh) and real consumption was 856-1316 kWh/calf/year (avg. 1065). Calculated total energy consumption of barns for Calf from 6 months to slaughter in the TE-center areas I-II was 1143-1745 kWh/calf/year (avg. 1444 kWh) and real consumption was 1630-2567 kWh/calf/year (avg.2065 kWh). In the TE-center III calculated energy consumption was 1392-1994 kWh/calf/year (avg.1693 kWh) and real consumption was 329-1327 kWh/calf/year (avg.689 kWh). In the farrow-growing pig hoconsumption in the TE-center areas I-II calculated energy consumption was 1197-1518 kWh/ pigplace/year (avg.1308 kWh) and real consumption was 1494-3331 kWh/pigplace /year (avg. 2233) TE-center area III calculated energy consumption was 1375-1695 kWh (avg.1327) The real energy consumption can not be found. Fattening feeder pig hoconsumptions calculated energy consumption was in TE-center areas I-II 213-296 kWh/pigplace /year (avg 255 kWh), real consumption was 154-1662 kWh/pigplace /year (avg.489 kWh). TE-center area III calculated energy consumption was 355-438 kWh/pigplace /year (avg 793), The real energy consumption can not be found. Domestic farms energy consumption calculation was succesful. Real energy consumption can not be calculated very precisely from Työtehoseura’s material. Työtehoseura’s material included en-ergy consumption that doesn`t directly relate to farming. Comparison between the calculated and real energy consumption was made only if real consumption was known. In the comparison some conformity with calculated and real energy consumption was found, but there was also big differences.
