Abstract

A Rural Energy Simulator was created using Microsoft Excel® and Microsoft Visio® with Visual Basic for Applications (VBA) in order to analyze some competitive production scenarios between food and renewable energy in rural areas. This linear programming simulator is able to derive an optimum solution from objective functions such as maximizing renewable energy production, or minimizing cropping surface area in rural areas with constraint conditions such as farmland surface area, food demand, feed demand, and energy demand.<br>The simulator was evaluated by comparing trial calculated data published in previous research papers on the estimation of biomass production. It was clarified that cropping systems in the rural agricultural area of Tochigi prefecture can be identified with enough accuracy for discussion by using the simulator, considering the real data and restricted conditions used in the previous research papers. Furthermore, some trial calculations for new scenarios were executed by using the simulator from the viewpoint of increasing the amount of production in food and energy along with effective use of rural agricultural areas in order to promote the construction of a self-sufficient society. The simulator automatically selected the best cropping system for a high energy conversion efficiency from many cropping combination patterns. The simulator identified some solutions for self-sufficiency in food in rural area with maximized biomass energy production and farmland utilization ratio, and minimized cropping surface area.<br>
