This study was conducted with the general purpose of developing strategies for the use of renewable energy in the agricultural sector in Bushehr province. In this study, first, using analytical studies and literature, the subject of the four SWOT points, namely strength, weakness, opportunity and threat, were identified and prioritized using the AHP technique. The statistical population of the study were subject-aware experts and specialists in relevant organizations who were purposefully selected for the study. Data analysis was performed using SWOT-AHP technique using Expert Choice software. Findings showed that in evaluating the criteria, strengths, weaknesses, threats, opportunities were the first to fourth priorities that the weights obtained from the results of these points indicate the dominance of risky space over space. useful. In addition, in prioritizing strategic areas, the results showed that the first SO strategy is aggressive strategy (maximum-maximum), the second strategy is ST strategy is contingent strategy (maximum-minimum), the third WO strategy is adaptive strategy (minimum-maximum strategy). And finally, the last strategy in the subject under consideration is the WT strategy, that is, the defense strategy (at least - at least). In general, the results of this research can provide new insights for energy and environmental policy makers.

Emission reduction of carbon dioxide and its impact on global warming process is one of the most important results in the use of renewable energy sources. In urban areas, solar systems stationed on building roofs are the most appropriate utilization method of stable source of solar energy. Urban compactness is a major urban form parameter that affects the accessibility of solar renewable energy in the built environment, so it is essential that the effects of urban compactness on buildings utilization of solar energy, be surveyed. The aim of this study is the evaluation of solar energy potential in urban areas and determination of the relation between urban compactness indicators and solar energy potential in the local scale. In this study, the annual solar radiation modeling for each of the building surfaces of the study area, over one year period, was performed using the Solar Analyst model. On the other hand, the relation between various compactness indicators including site coverage, plot ratio, volume-area ratio, Entropy, population density and building density with Annual solar radiation received by the study area was explored and using least squares regression model, the relationship between the solar radiation and urban compactness indicators was determined. Also potential of using two types of active solar systems including Building Integrated Photovoltaic Systems (PV) and Solar Thermal Collectors (STC) was evaluated. According to the results, the annual solar irradiation increase from 507 (in compression areas) to 741 (in scattered areas) Kilowatt hours per square meter. Volume-area ratio shows the highest determination coefficient, R2 equal to 0/805 with annual solar radiation. Also in the study area, the building roofs potential for the development of PV systems much more than STC systems, influenced by the degree of urban compactness.
