  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.

  Today, unemployment is caused by environmental and economic changes are burning quite a problem around the world. With startups over the past 10 years, the economy is showing more and more increasing trend, so why not make it against the climate change fight, even while the young entrepreneurs also support the economy. There are many things to do, which is still untapped, including the use of geothermal and renewable energy resources, which not only
  reduced dependence on foreign countries, but also new jobs could be created using environmentally friendly methods. The innovative emerging entrepreneurs’ maybe will soon find a solution for climate change, because this phenomenon is certainly all the inhabitants of the earth directly or indirectly exercise influence.

  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.
