The efficient conversion of the energy resources given to us by nature into forms suitable for human use is a prerequisite for the successful existence of modern society. Without a sufficient number of different types of energy it is impossible to provide humanity with drinking water and food, transportation services and warm houses, shining cities and familiar high-tech devices. People will always need energy available at any time, during periods of calm, during natural and man-made disasters or epidemics. However, the taming of natural resources should not cause problems – neither environmental, nor political, nor economic. These conflicting tasks must be solved by advanced energy technologies.
