  The spread of utilization of renewable energy resources is primarily motivated by objectives of energy policy and climate protection. However the rural and community development role of the new investments had got a greater significance in the past years. In the last years or decades the different renewable energy sectors became an important objective of regional policy. In parallel with these changes the renewable energy sources aroused the interest of potential investors. The low population density and relative richness of natural resources in rural areas provide favourable conditions for location of these investments. On the base of local economic development aspects was designated as positive effects that the investments utilize the internal resources of these regions. However in practice it raises different significant questions. What is the role of local financial resources, professional skills and sufficient number of customers in renewable energy investments? We cannot imagine authentic and successful rural development projects without considering the interests and participation of local communities. Our research focuses on requirements of prosperous and long-term sustainable renewable energy based community development solutions following Hungarian and European examples.

  Abstract

  In the European Union, the population uses 26% of the energy. Due to the strategic goal of achieving climate neutrality and the crises of recent years, investment in the use of renewable energies has accelerated. In order to support this process, the Circular Economy Analysis Center of the Hungarian University of Agriculture and Life Sciences (MATE) started the development of a so-called multidisciplinary smart map, which shows the possibilities of renewable energy sources that can be used locally, and the selection of the optimal energy production mix based on the location of residential buildings and buildings. The purpose of this article is to present the selection of test sites necessary for the development of the map, highlighting their geographical, meteorological, economic, and social characteristics. Based on the applied multi-criteria system, the selection of testing locations and tasks is a complex task. The investigations are summarized in five chapters. The first one describes the introductory thoughts related to the initiation and development of the project. The second deals with Hungarian residential energy consumption in the light of international data. The third presents the principles of smart map development and defines the criteria for testing locations. And the fourth one analyzes and presents the principles and possibilities of selecting locations. The fifth part summarizes the location selection process, describes the methodology of the applied analyzes and describes the results of the location selection. The described procedure can guide the examination of these factors in other international projects.

  Global climate change poses a significant threat to the planet and our well-being, with carbon emissions being a key contributing factor. The aim of this article is to delve into the complex system of factors influencing carbon emission trends among key countries, examine sectoral differences contributing to such emissions and understand the global actions taken to mitigate the climate change. For this purpose, both quantitative and qualitative research were conducted, and several statistics were used to provide a comprehensive insight on the subject. We have found that while industrialized countries have historically been major contributors to carbon emissions, the rapid economic growth and industrialization witnessed in China and other developing countries mainly in Asia have led to significant increase in their emissions in recent decades. Furthermore, not only regional but sectoral differences could be spotted as the energy sector, where fossil fuels remain a dominant source of energy despite growing efforts to transition to renewable sources, contribute the most to carbon emissions. Lastly, international climate conferences, such as the landmark Paris Agreement, as well as the current energy strategy in EU have sought to mobilize global and regional efforts to mitigate climate change and achieve net zero emissions.

  The undiminished development of air traffic has a direct effect on the environment of airports. Year in year out the continuously growing passenger traffic has increased the number air flights. The technological development has made it possible to increase the size and performance, - and with it the transportation of heavier payload - of aircraft. Of course, it has necessarily resulted in more fuel use (burnt fuel) emitting more pollutants into the atmosphere. In addition this effect appears not only during the high altitude flying polluting the high atmosphere, but due to the today very busy and the continuously increasing ground aircraft motion (taxiing) contaminating the close surroundings of the airport. With some innovation and technological development we can make the airports not only more environmentally friendly but also cost effective. In this paper I would like to introduce the possible use of renewable energy sources and the ground movement of aircraft without their own engines.
