Since the last decade, the concepts of green innovation and green economy have become more and more attractive to researchers and policymakers. This research brings some light to the association of those themes with the concept of green energy. Therefore, this paper is a critical review of the green innovations directed explicitly to the green energy challenges faced by organizations and the world economies. The research question is as follows: What are the main dimensions of a model to implement a green innovation process focused on green energy in organizations? The methodology used to answer the research question was qualitative, and the main techniques included a systematic literature search and survey. The main findings of the study were the identification of the most relevant dimensions of a green innovation model to be implemented in organizations. The article structure is based on the different concepts about innovation and green innovation, related to the green economy, and the analysis of two situational cases on green energy. Finally, we present the analysis made on the articles identified by the literature survey and the green innovation model. By making this research on green economy and related concepts of green innovation and green energy, this paper seeks to make a valid contribution to their definitions and for operationalizing the green innovation model in organizations.
