As the response to the financial downturn and arising social problems, eco-innovation flagship was elaborated as one of the main building blocks for sustainable, smart and inclusive growth. Nevertheless, the experts are increasing pointing out, that we are missing one important link, while focusing mainly on technical innovations and natural environment, social aspect is mostly disregarded. This social aspect includes human, economic, policy, organisational and other interactions in the system. By bringing together these three sectors – social, technical and natural environment – studies on so called socio-technical system is created. Currently, the studies using social and technical aspects for the research on transition processes are fragmented, both in terms of studied sectors, used methods and scientific fields. Especially, in the field of energy research the majority of the works study techno-economic aspects of the systems, while only few attempts have been made to incorporate socio-technical perspective as well. There are also identified clear lack of a holistic methodology, therefore the aim of this paper is to attempt to link engineering and social science study field to create such modelling approach. Socio-technical transitions are viewed from the perspective of various sectors, such as energy use, energy production and management, innovation diffusion and other. Also the transitions are looked from the scientific lenses of various possible methods and combinations of those. And last but not least, theses transitions studies are considered from the perspective of various scientific fields, both engineering and social science.
