The present state of energy production and utilization requires introduction of innovative technologies to mitigate impacts on the environment, to reduce fossils consumption etc. There are numerous environmental, economic, political issues have to be taken into account for renewable energy. Comprehensive research of all issues is possible by means of geodatabases and GIS routines that allow us to perform analysis and get particular results. This paper is devoted to construction of geodatabases dealing with unconventional sources of energy. We described a conceptual model and the ways to improve its completeness. There are suggested several algorithms of data processing that demonstrate database application and evaluate data integrity. The suggested approach is based on the idea of modeling not only database structure but also its future application. It is recommended to perform such modeling in the beginning of geodatabase development. The approach is unconventional for renewable energy practice and can be used in future for scientific and applied works.
