Research and development works on practical application of natural energy utilization systems involving solar, wind and sea wave energies are under promoting for the purpose of improving the energy consumption structure. These natural energies, made available with the use of relatively simple apparatus, are clean economically efficient and highly effective in the conservation of environment. However, these natural energies also have low energy density, randomness and regional variations. To compensate for these characteristics, hybrid utilization of solar and wind energies is. currently under study.<br/> The introduction of a plural number of the natural energy hybrid utilization systems into a specific area will affect the economic efficiency, reliability and environmental conservation. Evaluation method of such effects has been examined in this study.<br/> The present method consisted of the steps described below. First, available energy was calculated from insolation distribution and wind velocity distribution in the specified area, and then the effect on the configuration of the power system load was obtatined. This was followed by the determination of the optimal power dispatch over the specified period and by evaluations in light of economic efficiency, reliability and environmental indices.

In response to the rapid climate change, in order to save energy in the field of buildings, the country is planning not only zero energy buildings but also zero energy cities. In the Urban Development Project, the Energy Use Plan Report is prepared and submitted by predicting the amount of energy demand at the planning stage. However, due to the activation of zero-energy buildings and the increase in the supply of new and renewable energy facilities, the energy consumption behavior of buildings in the city is changing from the previous ones. In this study, to estimate urban energy demand of Zero Energy City, building energy demand forecasts based on “Passive plans for use of energy based primary energy consumption”, “Actual building energy usage data from Korea Appraisal Board” and “data from Certification of Building Energy Efficiency Rating” as well as demand forecast according to existing “Consultation about Energy Use Plan Code” were calculated and then applied to Multifunctional Administrative City 5-1 zone to compare urban total energy demand forecasts.

The renewable energy information becomes one of the greatest issues all over the world because of serious environment problems and limited fossil resources. The renewable energy resource information system is treated seriously for efficient management and distribution as dealing with these energy problems. Especially, it is difficult to manage and utilize solar energy information because gathering and surveying information is progressed individually in each research equipment. Therefore this paper will establish ISP(Information Strategy Planning) and propose the resource management system based-on GIS to analyze the solar energy and build the integrated management system. The proposed resource management system can provide spatial analysis using thematic map, data search, data import/export and interpolation about users’ queries.
