Experts have achieved tremendous success in space technologies, as well as in the field of electrical energy Earth supply systems. It is time to join efforts of scientists who work in both spheres because these problems are tightly connected. This paper is an attempt to show that studies concerned with power system development, including the formation of a Global Power System (GPS) should be considered as an important part of studies concerned with transmitting clean energy from space to Earth. Some results of investigations on specific features of a power system in different regions of the world are addressed by experts who look for suitable sites for the reception of Space‐Earth electricity transmission systems. ©American Institute of Physics 1995
