This article systematically reviews the emerging field of research on business models for renewable energies, differentiating between developing and industrialized countries. The key findings on developing countries are as follows: first, there is a lack of quantitative data;second, opportunities are driven primarily by unfulfilled basic needs and micro-finance, whereas corruption and weak electricity grids are the main barriers;and third, business models should be replicable. The key findings on industrialized countries are as follows: first, opportunities are driven primarily by climate change mitigation and energy efficiency improvements;second, stuck thought patterns and high costs of energy storage are important barriers;and third, cooperation is a key in future business models to handle increasing complexity. This review reveals implications for researchers and policy-makers. Promising avenues for future research are the analysis of intermodal business models and opportunities concerning energy self-supply and renewable district heating. Policy-makers are advised to design legal frameworks that account for the global nature of the renewable energy challenge and are simultaneously adapted to regional disparities.
