<p>Neither regional development, construction projects nor infrastructure development – structural planning does not fully consider energy supply in Austria (yet). The project “Spatial Energy Planning for Heat Transition” is part of the research initiative “Green Energy Lab”, which has a project life-time from June 2018 to May 2021. It aims to provide a sound basis for the integration of heat in private and public planning processes and for the implementation of the energy infrastructure of the future together with energy providers.</p><p>Three Austrian states (Vienna, Styria and Salzburg), their capital cities and pilot-municipalities of all scales work together to provide all information necessary for the implementation of spatial heat-planning – as role model for Austria and other European countries. The GIS-based web-tool “heat-atlas” will provide this harmonized data and serve an information platform for project developers as well as for regional planning, fostering a sustainable use of all available sustainable energy resources and infrastructures to their full extent. The system of the information platform is arbitrarily scalable and is aimed to be expanded to other interested regions of Austria on demand.</p><p>One part of this “heat-atlas” is about shallow geothermal energy and covers vertical closed loop and open loop systems. The Geological Survey of Austria developed new methods to estimate capacity and energy resources as well as to show possible limitations of shallow geothermal energy use on property level. The resource calculations combine location-specific parameters such as thermal conductivity, underground temperature and groundwater availability with system-specific parameters such as mode of operation, operational hours, geometry and threshold values demanded by official regulations.</p><p>The method provides not only information about the maximum amount of energy available on the property, but also about the cover ratio of the demand. So called level-1 maps show the resources for standardized well-doublets and borehole heat exchangers independently of the property. The calculations for level-2 maps consider site-specific properties such as heating and cooling demand, operational hours and size of the property. This enables the estimation of the overall energy resources and the cover ratio of the property.</p><p>The results are shown as maps and as location specific query, which gives a concise summary of all relevant information for one location in form of an automatically generated report.

Humanity faces several environmental challenges today. The planet has limited resources, and it is necessary to use these resources effectively. This paper examines the environmental impact of three energy solutions for the heating and cooling of buildings. The solutions are conventional district heating and cooling, a smart energy solution for heating and cooling (ectogrid™), and geothermal energy. The ectogrid™ balances energy flows with higher and lower temperatures to reduce the need for supplied energy. The three solutions have been studied for Medicon Village, which is a district in the city of Lund in Sweden. The study shows that the energy use for the conventional system is 12,250 MWh for one year, and emissions are 590 tons of CO2 equivalents. With ectogrid™, the energy use is reduced by 61%, and the emissions are reduced by 12%, compared to the conventional system. With geothermal energy, the energy use is reduced by 70%, and the emissions by 20%. An analysis is also made in a European context, with heating based on natural gas and cooling based on air conditioners. The study shows that the environmental impact would decrease considerably by replacing the carbon dioxide intensive solution with ectogrid™ or geothermal energy.

This paper reviews the current state of the renewable energy use in Serbia. Further on, the paper describes energy potential and gives examples of the use of solar energy, wind energy, hydropower, geothermal energy, biomass and biogas in Serbia. Extensive body of information is given about support systems and measures of incentives for the investment in the construction and sale of electricity from plants using renewable energy sources. In conclusion, achieved results of the use of renewable energy sources in Serbia and the incentives for their use are presented.

Bilateral Cooperation

This paper discusses the obstacles in Icelandic-Indonesian cooperation related to geothermal development in Indonesia in 2007 - 2014. In the cooperation process that prioritizes geothermal energy use in Indonesia, the interaction between Iceland and Indonesia has not shown significant implementation results, mainly technical geothermal energy exploration. This cooperation has been going on for seven years. The concept of Barriers to International Cooperation developed by Lauri Siitonen, which is a derivative of the idea from Theories of International Cooperation, is used to analyze existing obstacles. This concept explains why cooperation and obstacles can occur due to the interactions of the actors involved. In this case, each country's national interests, which become the foundation for interactions in the international system, can create political policies that often ignore bilateral cooperation objectives. This research is based on primary data and secondary data with descriptive-analytical methods. This paper's conclusion shows that political and policy factors and technical factors are significant in hindering this cooperation.
