Summary: | Electricity is a general term for a variety of phenomena resulting from the presence and flow of charge, and “Electro-technics” is the study or the science of practical and industrial applications of electricity. On the other side, the space is mainly characterized by the interaction of energetic charged particles with electric and magnetic fields, which justifies the claim «the space composes a natural laboratory of electrotechnics». This paper reviews present understanding of the dy-namics of the solar-terrestrial environment, and its impacts on the human activity, and explain processes, which establish the space as a natural laboratory of electrotechnics.
