REGIONAL POTENTIAL FOR SUSTAINABLE ENERGY SUPPLY IN CROATIA : MASTER'S THESISStefan Subotić
, master's thesis
Abstract: The master thesis aims to find the optimal model for a new energy company that considers regional potential, supports sustainable development, and fits the circular economy concept in a region. The idea of sustainable development is crucial today when we have more city areas and less countryside around the globe. Increased global population, industrial trends and modern living style are some of the reasons why the burden on our environment is more significant than ever in the history of humanity. The idea is to launch the new company in the Croatian region Osijek-Baranja, which is less developed and not attractive to tourists. A newly established company will produce electric energy from renewable energy sources. The multi-criterion decision support methods were used to determine the optimal energy source between wind, biogas and sun. Results show that the biogas has the most significant sustainable potential in chosen boundary conditions. The cash flows and other economic indicators are shown for a farm of 500 milking cows in the chosen region as a source of biogas. The risk assessments method estimated the boundaries of the company success and adaptability to possible changes. One of the critical aspects of the project is the company's organizational structure, where a vertical hierarchy with a flexible and fluid, circular organization model with network culture was proposed. Clear communication about the project will help establish trust with the local community. Based on the biogas plant, the proposed company reduces biodegradable waste in the green energy production process. It is shown quantitatively that besides being economically sustainable, it also suits the region's potential, supports energy self-supply, and involves local people - it aims to the long-term sustainable growth of the region, rather than short-term capital growth.

An economic analysis of biomass potential as an opportunity to increase the share of biogas production for energy purposes in Slovenia : master's thesisStefan Dabižljević
, 2021, master's thesis
Abstract: One of the biggest global problems, the solution of being put in front of the scientists around the world, is endangering the environment. To preserve it, the transition from non-renewable to renewable energy sources is a rational and necessary solution. One of the energy sources with great potential in the future is biomass. In the master’s thesis, we have studied the economic analysis of the possibility of obtaining energy from biogas in Slovenia for the production of which biomass is used. For the study to be successful, it was necessary to analyse the situation in the field of renewable energy sources and biogas in the European Union and Slovenia to obtain a general picture for further analysis. By analysing the available data from previous years, we gained insight into the situation in the given area. The master’s thesis aims to show that although Slovenia has been facing the problem of a decreasing number of biogas power plants for years, the implementation of a system for obtaining energy from biogas is an economically and environmentally viable investment. The economic analysis was done for a 1 MW plant. The choice of plant size and power was made based on the Kepner-Tregoe method and the method of comparing alternatives. For the project duration of 30 years, through cash flows, as well as through various economic indicators, such as the presentation of loan calculations with a certain interest rate, internal rate of return, repayment period method, present project value, etc., the economic side of the investment is presented, which aims to show the profitability of the project.
