Over the past half-century, scientists from many different areas have been investigating how to switch to renewable energy, especially in the context of a circular economy. Numerous articles have discussed the scientific aspects of developing technology to support this process. This systematic literature review and bibliometric study aim to fill in research gaps by looking at trends, challenges, and possible future directions for the use of renewable energy in the context of a circular economy, especially in the fields of business, management, and economics. The study analyzed 294 peer-reviewed articles using the R Studio-Biblioshiny package version 4.1.2 software. The challenges of integrating renewable energy technologies within a circular economy include financial constraints, such as a high initial investment, the lack of an adequate regulatory framework and government support, the intermittent availability of renewable energy sources, the scarcity of resources and components for renewable energy generation technologies, relatively low energy conversion efficiency, the challenge of increasing consumer awareness, and the environmental impact of technological waste. The study suggests that future research should focus on financial models and policy incentives that can encourage businesses and investors to take advantage of renewable energy. The study also recommends exploring sustainable alternative fuel technologies, optimized waste-to-energy conversion, the increased efficiency of bioenergy conversion, more efficient solar panels, improved energy storage capacity, the life cycle management of solar panel devices, and the development of innovative business models to facilitate industrial symbiosis.
