This paper aims at discovering a suitable theory for understanding the adoption of renewable energy (RE) among investors and decision-makers in the Egyptian market as well as disclosing the research gaps related to examining the drivers that affect spreading RE sources in the various societies. Finally, it will explore the factors that influence the adoption of RE in different organizations to increase the diffusion of RE inside the Egyptian society. Therefore, it is important to understand how business customers select the type of energy whether conventional energy or RE or mixed. Hence, this study examines the drivers that influence business customers’ choices of RE versus conventional energy for pushing toward adopting the RE investment inside the firms. Exploratory research is used in this investigation; therefore, data for this study is collected using literature reviews, international and local reports, in addition to unstructured interviews with potential and actual customers as well as practitioners and academics in the RE sector. This study will benefit Egyptian policymakers and RE companies in the marketing of RE sources through understanding the drivers of adopting RE within businesses.
