      abstract = {Energy efficiency measurement is crucial when planning  energy reduction policies.
However, decision makers  understandably will be reluctant to act in the absence of  solid data
and results supporting a policy position. The  main objective of this paper is to propose an
alternative  method to measure farm energy efficiency. This method is  based on the Data
Envelopment Analysis (DEA) approach in a  cost framework introduced by Farrell (1957) and
developed  by Färe et al. (1985). We decompose the energy efficiency  measurement into two
components, namely technical and  allocative efficiencies. Here, input prices are replaced  by
their energy content. The energy efficiency model is  used to explore the optimal input-mix
that produces the  current outputs at minimum energy-consumption. We show that  this
decomposition can help policy makers considerably to  design accurate energy policies. The
presence of  uncertainty on data, and more particularly on energy  content of inputs, leads us to
recommend exploiting the  methodologies proposed for calculating the bounds of  efficiency
measurement in order to produce more robust  results. We expect to alert policy-makers in the
fact that  efficiency is not a fixed value and should be considered  with caution. A 2007
database of French farms specialized  in crops is used for empirical illustration.},
