International science faced the topic of the attitude to new sources of energy in the 1990s, though domestic scientists still do not pay proper attention to this problem. In the field of studying the attitude to new sources of energy abroad, the 1990s also became a turning decade, which was followed by a transition in understanding what is a new source of energy: as such, nuclear power is gradually losing its popularity, giving way to the new ones, i.e. renewable energy sources. This trend in science since its inception and to the present time is widespread, mainly, in Europe and the United States – in those regions in the economies of which new sources of energy begin to play significant roles.
