1. Insights Taken from Bibliometric Analysis of the Several Dimensions for Energy in Agriculture

The concept of energy associated with the agricultural sector has several dimensions and is interrelated to different issues both directly and indirectly. In fact, the energy consumption in farms is interrelated to their internal characteristics, such as performance, competitiveness, efficiency, type of agricultural system and assets. External dimensions, namely those related to agricultural policies also have their implications on energy use by farms. The agricultural policies, within the framework for the Common Agricultural Policy, through its several instruments and measures are determinant in the evolution of agriculture in the European Union, in general, and for farm energy use, in particular. In this context, the main objectives of this research are to highlight the main insights for the several dimensions of the energy concept in the agricultural sector from scientific publications. To achieve these objectives a bibliometric analysis was carried out, considering the documents available in the Web of Science (Core Collection) for the topic “agr* energy”. The consideration of the topic for the search, in this way, allows for a wider analysis. As main insights, it is worth highlighting the importance of concepts such as the efficiency in the farm energy use, competitiveness, network, renewable and alternative sources of energy and decarbonisation. Researchers affiliated to institutions from the USA, European countries, China, Brazil and Canada are the most productive and cited ones.
