On the example of conceptual transition from “cowboy” (resource-intensive) to “spacemen economy” (based on renewable resources use and closed cycles of material reproduction) proposed in the 1960s by K. Boulding the article discusses the features of the contemporary transformation processes of sustainable (“green”) economy formation during the Third industrial revolution. Based on the analysis of the nature of the prerequisites for the formation of green economy and the challenge that it seeks to solve its main features are described. In a popular form of fairy tales the distinction between “brown” and “green” economies, and especially the key components that determine the profile of the Third industrial revolution, including 3D-printers, solar panels, wind generators, battery technology are characterized.
