In the context of agriculture, research has focused predominantly on the production of bio-energy, while only a limited number of studies have investigated the energy use and possible energy saving in conventional agricultural production. In response to this lack in empirical research this study aims (i) to measure the farm-level energy and cost efficiency of conventional agricultural (wheat) production, (ii) to identify the potential for energy saving in conventional agriculture and quantify its shadow cost, (iii) to identify production technologies and managerial practices that reduce total energy use. We adjusted the method by Coelli, Lauwers, Van Huylenbroeck (2007) introducing analogy between cost and nutrient minimization to measure energy use reduction potential and its costs. The analysis was carried out on survey data for 95 farms for production year 2007/08. Energy coefficients for individual non-renewable inputs were derived from the PLANETE methodology (Méthode Pour L'Analyse EnergéTique de l'Exploitation) developed by SOLAGRO. We applied data envelopment analysis to estimate energy and cost optima and efficiencies, and truncated regression to identify statistically significant determinants of energy efficiency. We found significant differences in energy consumption per unit of wheat production among Czech farms - best producers consume 46% less energy per unit of production than average producers, however, from that ca. 30% is due to variation in production conditions. Marked share of energy inefficiency (over 50% of potential energy savings) originates in technical efficiency, which offers simultaneous cost savings. Producing wheat in energy optimum would increase costs by 9% when compared to cost optimum. The largest potential of energy savings was found in fuel, and fertilizers and other chemicals. Regression analysis implies that use of more fuel-efficient machinery or machinery with other energy-saving technical parameters (e.g., higher utility weight) and optimizing material transport could increase energy efficiency, while some commonly applied technological practices (such as conventional soil preparation) have a negative energy efficiency effects. 000103410 546__ $$aEnglish 000103410 650__ $$aAgribusiness 000103410 650__ $$aCrop Production/Industries 000103410 650__ $$aProduction Economics 000103410 650__ $$aProductivity Analysis 000103410 6531_ $$aEnergy efficiency 000103410 6531_ $$acost efficiency 000103410 6531_ $$ashadow cost of energy saving 000103410 6531_ $$aagriculture 000103410 6531_ $$aCzech farm 000103410 6531_ $$awheat production 000103410 700__ $$aCurtiss, Jarmila 000103410 700__ $$aJelinek, Ladislav 000103410 8564_ $$9d6dbf3e1-f143-4342-b1e8-1008dbb3c6f3$$s1098777$$uhttps://ageconsearch.umn.edu/record/103410/files/Poster_AAEA2011_ID13198_Curtiss_Jelinek.pdf 000103410 887__ $$ahttp://purl.umn.edu/103410 000103410 909CO $$ooai:ageconsearch.umn.edu:103410$$pGLOBAL_SET 000103410 912__ $$nSubmitted by Jarmila Curtiss (curtiss@iamo.de) on 2011-05-01T23:02:33Z No. of bitstreams: 1 Poster_AAEA2011_Curtiss_Jelinek.pdf: 1098776 bytes, checksum: c2d399ae7173acd8966b74c145b9cf73 (MD5) 000103410 912__ $$nMade available in DSpace on 2011-05-01T23:02:35Z (GMT).
