Energy Autarky of Rural Municipality Created on the Basis of Renewable Energy Resources

摘要

The aim of this study was to assess the potential of meeting the energy needs of a rural community using renewable energy resources. The research was conducted in the municipality of Rakow in the Swietokrzyskie Region. A new aspect of the research is an attempt to balance current and potential energy production from renewable sources. The studies included such resources as: solar, hydro, wind, and biogas derived from energetic and forestry plants. We divided renewable sources into existing, potential, and overall for a period until 2020. The assessment of the current state was based on a stocktaking of existing sources of energy, and prospective on the basis of potential and real opportunities, and trend analysis of the development of these energy sources. Currently, renewable sources cover only 2.2% of energy needs of the community, while electricity covers about 24% of the demand. The production of heat from renewable sources can now cover the needs of 120%, and has the potential to cover in 256%, including the biomass obtained on set-aside of 30%. The surplus of heat energy can be transferred to the outside.
