Comparative uncertainty analysis of energy coefficients in energy analysis of dairy farms from two French territories

► Energy, uncertainty and sensitivity analyses of dairy farms from two French territories. ► Average fossil energy use for dairy farms of 4.6 MJ L−1 for PC and 7.9 MJ L−1 for RI. ► Need for locally adapted energy coefficients highlighted by uncertainty analysis. ► A sensitivity analysis to identify most influential coefficients which should be adapted.
