The intensifying and modernization of agriculture, in spite of improving the productivity, it caused a complete petroleum derived dependence, so much in the form of fuels, lubricants and machinery, as in the form of inputs for the production. This work had as objective to esteem the energy inputs and outputs and the energy conversion, in two different local, in the west of Paraná State/Brazil. The largest consumption was observed for the direct energy category, with 95.6% and 95.28% in Cascavel and Palotina, respectively. In the direct energy flow, the Palotina prodution spent 5,0% more. The consumption of fossil energy was of 22.32% for the Palotina farm and of 23.84% for the Cascavel farm. The energy conversion was of 3.2 and 1.8, for the wheat productions in Cascavel and Palotina, respectively.
