One of the EU headline target indicators for Europe is “20% increase in energy efficiency” by 2020. It is anticipated that in the following decades energy use will increase significantly and will have a widespread impact on the economy, including the agricultural sector. Energy use reduction can be achieved by reduced energy input. Improved energy efficiency, however, is only achieved, if energy input per unit yield is reduced. Therefore, improved energy efficiency can be realized with either increased or decreased energy inputs depending on the input-output relationship. In agricultural production the need for energy as an input can determine the profitability of farming which, in turn, impacts heavily upon the farmers’ investment in improved farming systems. This paper presents some of the results obtained in the WP2 of the KBBE.2011.4-04 project “Energy Efficiency in Agriculture - AGREE” supported by the 7th Framework Program. It gives an overview into energy use and energy efficiency of agriculture in various agro-climatic zones of Europe.
