  The importance of the research of the biofuels is moti vated according to the Hungary’s Renewable Energy Acti on Plan, on the other hand the Europe 2020 also emphasizes the smart and sustainable growth. The direct objecti ve of the research program is to investi gate the applicati on of microwave pre-treatment for bio-energeti c, the indirect objecti ve is to ensure security of energy supply. Based on the experiences, the microwave energy is preferably used for intensifi cati on of certain chemical reacti ons. Pre-experimental experiences have shown that microwave irradiati on in the transesterifi cati on of vegetable oils (transesterifi cati on with methanol and NaOH catalyst) results in reducti on of ti me and energy demand of the process. Producti on of vegetable oil-based is made with microwave-assisted technology under diff erent method, operati onal and process parameters. As a result of the experiments established that the
  transesterifi cati on reacti on ti mes of the microwaved transesterifi cati on are reduced signifi cantly compared to the conventi onal transesterifi cati on reacti on ti me, however, further investi gati on of compositi on of treated mixture and dielectric characteristi cs of the components are necessary to optimize the procedure for energy aspects.

  The study has thoroughly presented the classic and new trends of economic gr owth, and on this basis, it can be stated that this is a complex system, and its analysis is almost always relevant, mostly because of the rapidly changing global systems and networks of contacts. The economic growth is extremely important in the 21st cent ury as well, but with a new approach. Two very important factors appear: sustainability and social development. Albeit the economic growth and
  the social development are in the opposite directions, not serving the basic idea of sustainable development at all. In this study, we aimed at portraying the complexity of this system and the range of factors influencing it.

  The central thought of this article is the relationship between the stability of public finances and the sustainable economic development of the country. The paper aims to find an answer to the question to what extent the outer and inner conditions of the social and economic functioning have contributed to, and hindered the domestic development in the quarter of the century after the change of the regime. The article proves that stability and growth are predisposed to strengthen each other. In absence of financial stability, we cannot talk about competitiveness as a prerequisite for the sustainability of growth, or in a wider sense, the realization of the public good. The latter can be observed basically in the fact that the interests of financial stability and growth are in equilibrium and the satisfaction of socio economic needs is realized in the frame defined by them.
