Енергетска безбедност Европске уније у светлу актуелне енергетске транзиције
Бобан Павловић, Дејан Ивезић (2021)Енергетска стратегија Европске уније, која од 2015. године обухвата и циљеве у области климатских промена, тежи изградњи „енергетске уније” која потрошачима из ЕУ даје сигурну, приступачну, чисту и одрживу енергију. Енергетска политика ЕУ поставља пред себе амбициозне циљеве у погледу коришћења обновљивих извора – учешће од 32% до 2030. године. Овако опсежну и динамичну енергетску транзицију у Европи усложњава хетерогеност националних енергетских система у погледу структуре енергетског микса, нивоа увозне зависности, као и нивоа технолошког, друштвеног и економског ...енергетска безбедност, Европска унија, енергетски показатељи, природни гас, обновљиви извори енергије... појмовном оквиру смањиле и да би се, у крајњем циљу, могла вршити квалитативна и квантитативна анализа енергетске безбедности у различитим држава и регионима, у теорији је заживео приступ који апострофира „вишедимензионалност” енергетске безбедности.

The application of ArcGIS for assessing the potential of solar energy in urban area: The case of Vranje
In order to determine the solar energy potential for a specified location, it is crucial to consider the latitude, altitude, slope, terrain morphology, atmospheric conditions, etc. Such a complex calculation and mapping of solar energy can be done using the ArcGIS geoprocessing tool, named Area Solar Radiation (ASR). By using the ASR tool, supported with the adequate input data, it is possible to calculate the maximum solar radiation energy (irradiation) for a defined area and for a specified time ...... panels (for heat and electricity production) can be installed on rooftops. The methodology was tested for the city of Vranje, located in the Southern Region of Serbia.
