With the ever wider application of renewable energy sources and the spread of knowledge about their importance and inevitability in decarbonization and slowing down and stopping climate change caused by the extensive use of fossil fuels, these technologies cease to be only the subject of energy, and increasingly become the subject of discussions about the social acceptability and profitability of such projects. The social acceptability itself rests on the basis of the local population's concern about the possible devastation of the location of renewable energy projects and on the understanding of the benefits of such projects for the local community. While the environmental impact is reviewed through mandatory environmental impact assessment procedures and the creation of a study that covers all environmental aspects of such projects, the benefits for the local community are often not clearly presented and thus difficult to understand for people outside energy sector. In addition to wider benefits related to the reduction of greenhouse gas emissions, the development of the electrical energy network and the creation of preconditions for the development of modern industry, the legal provisions clearly specify the amounts that the owner of such a project is obliged to pay into the budget of the city or municipality on whose territory the project is located. The obligations determined in this way are not small and can vary from three to five percent of the total income each year, which for the budgets of rural municipalities become significant non-designated funds that they can freely dispose of. However, the need for an even stronger connection between the local population and the economic dynamics of such projects has become apparent. This final thesis deals with one of the methods of local community investment in large projects of renewable energy sources and the effect of such investment on the profitability of the project itself. The example of opening a smaller part of the project for investment to the local community will prove the hypothesis that such investment does not have any negative effects on the profitability of the project itself.
