Abstract
Diffusion of renewable energy utilization is difficult because of its entrepreneurial nature and related technological, investment, political, and market uncertainties. Therefore, evaluation of business structure based on traditional business models is difficult in this industry. Although many countries have actively developed renewable energy technologies by both governments and private sector, business professionals are not still assured about participation and investment. Understanding the areas of business structure that lead to successful commercialization of renewable technologies has suitable research scope in this industry. The objective of this article is to identify key areas of business structure to allow newcomers to enter successfully in the renewable energy industry from engineering, policy, and business aspects. The innovative analysis leads to identification of seven sides of renewable energy business.
