Fossil energy carriers may be rated among non-renewable energy sources. These energy sources have aggregated during more hundreds of years. The huge energy demand of human activity may largely be covered by using fossil fuels. These are usually the divergent variants of hydrocarbon: hard coal, petroleum, natural gas more their variants.

Nuclear power may also be rated this group, since its raw material, the uranium is not a renewable energy source either. The use of these substrata gives rise to environment pollution. In the course of the fossil fuels destruction by fire, carbon dioxide, carbon monoxide, nitrogen oxides and other harmful pollutants get into the atmosphere, and they alter the optimal air composition. The extended concentration of carbon dioxide and methane are responsible for global warming. Uranium that is used as fuel, endangers the health of human and animals.

Besides air pollution, there is another problem:- the stocks are getting scarcer. The drastically increasing energy demand may be satisfied by the spares merely for a restricted period of time. The stocks upgrowth has slowed down. This is indicated supremely by the ever rising energy prices, which has economic-social effects. Energy demand in prospect can only be obtained only by abolishing wastefulness, by progressiveness in science and technology, by the application of new energy sources, and most of all by altering human approach.

We posses excellent geologic capabilities, the continental bed rock of the Pannonian basin is thinner and its thermal conductivity is better than the world average, thus heat which flows form magma more efficiently heats water quantities which lie in upper-Pannon loose sandstone and cracked lime-stone reservoirs. The average value of the geothermal gradient is about 1°C per every 20 meter when moving down. This heat may be utilized in many ways as a source of energy. (earth heat, thermal water/heating, energy production).

Our divergent chemical, ceramics or building industrial raw materials were negotiated as natural subsurface energy sources, sithence they serve as a raw material in certain industrial sectors, hereby the import of those given substrata are less required, and moreover some substrata there also remain for export.
