In tih thesis, te possibilities of utilizing EU funds to promote structural development in Croatia will be explored. Throughout its history, the European Union has enabled and continuously supported the structural development of its member states through financial resources from EU funds. The utilization of these funds facilitates various activities, such as investments in renewable energy sources, the advancement of tourism and hospitality, modernization of agriculture and fisheries, digitization of the public sector, and the employment of vulnerable groups. Examples of successful countries like Slovenia, Czech Republic, and Slovakia demonstrate how utilizing EU funds can revitalize national economies. Croatia, with its geographical position and rich coastline, holds significant potential for independent renewable energy production, tourism development, and digitization of public administration. However, it is crucial to educate and raise awareness among the Croatian population about the opportunities presented by EU funds to fully maximize their potential. This thesis will highlight the importance of renewable energy sources and energy refurbishment of multi-residential buildings in Croatia. Efforts need to be made to educate and develop a skilled workforce capable of implementing projects financed by the European Union. Furthermore, emphasis will be placed on investing in the educational system to ensure that young individuals acquire relevant knowledge and skills for the implementation of projects funded by EU funds. Through this thesis, the aim is to provide an expert overview and summary of the possibilities offered by EU funds to stimulate structural development in Croatia. Additionally, the significance of renewable energy sources and energy refurbishment of multi-residential buildings will be emphasized as key areas that require focused investments and activities.
