Összefoglalás.

Napjainkban az energetikai kérdések soha nem látott publicitást kaptak. Szinte nem találunk olyan sajtóorgánumot, melyben az energetikát érintő dilemmák ne lennének a témák fókuszában. E kiemelt szerepet az indokolja, hogy nincs már olyan emberi tevékenység, amihez ne lenne szükség energiára. Ráadásul egyre fokozódó mértékben használunk fel energiát mechanikai munkavégzésre, ipari célokra, fűtésre, világításra, s ez a mai civilizáció fejlődésének egyik igen jellemző vonása. Az energetika klasszikus műszaki szerepén túl az egyik legösszetettebb tudományág. Az energia-társadalom-gazdaság-környezetvédelem négyes fogalmi rendszere úgy biztosítja a fenntarthatóságot, mint az asztal négy lába az asztallap stabilitását. Ha bármelyik láb megsérül, szerkezeti instabilitás következik be. Vagyis az energetika „asztallábainak” stabilitására ügyelnünk kell, mert így biztosíthatjuk a fenntartható fejlődést.

Summary.

Nowadays, energy issues are receiving unprecedented publicity. It is almost impossible to find a press product that does not focus on energy dilemmas. This prominence is justified by the fact that there is no human activity that does not require energy. In addition, the increasing use of energy for mechanical work, industrial purposes, heating and electricity is a very characteristic feature of the development of civilisation today. There is a demonstrable correlation between the standard of living of the population of each country and per capita energy consumption, with productivity being a close function of the kW value per worker.

Today, it is getting increasingly important to ensure the sustainability of development, being one of the prerequisites for this is the availability of the sufficient quantity and quality of energy. At the dawn of the third millennium, society has reached the point where we cannot imagine life without the availability of different energy sources, and the use of energy, or the consumption of energy, has become part of our daily routine.

Just think it over, what we will do if we find ourselves without electricity, even for a short time - in everyday terms, “There is a power cut”. We immediately reach for our battery-powered mobile phones and call our neighbours and the electricity company to find out when we will have electricity again. We have to admit that we cannot live without energy these days.

In our article, we have summarised the main challenges for the operation and development of power plants. In the course of our work and our writing, we have made a kind of inventory. A clear direction can be seen, whereby all alternative technologies are getting more and more important in the global electricity mix.

However, we must face up to the challenges and difficulties, which must be seen not as problems but as tasks to be solved. Neither in energetics nor in other engineering fields should we delude ourselves. In our opinion, questions arising in the fields of technical sciences and engineering fields, will be answered and completed by investigations based on realities and facts, and the problems that arise will be solved and treated as challenges.

Beyond its classical technical role, energetics is one of the most complex disciplines, which is based on the knowledge of several specialized fields. The four concepts of energy-society-economy-environment ensure sustainable development such as the four legs of a table ensure the stability of a tabletop. If any one of the legs is damaged, structural instability will occur in the stability of the table. In other words, we must take care of the stability of the energy sector’s “table legs”, because this is the way we ensure sustainable development.
