Trends and future studies on policies to improve renewable energy share

Abstract

Every country needs to set up robust policies to reach its future targets in renewable energy development. The objective of this article is to explore the trends and research opportunities in this subject area. Systematic Literature Review (SLR) is applied together with bibliometric analysis to satisfy the objective. The database used in this study is Scopus considering its size and wide acceptance by major publishers. This study applies structural literature review and bibliometric analysis within one of its stages. A simple meta-analysis is cooperated prior to other analyses in this study. Various models are exercised to analyse important aspects in renewable energy policies, namely Input-output models, CGE models, Theory-based evaluation, multi-criteria analysis, and hybrid approach. Nonetheless, renewable energy is considered as a complex system. Therefore, advanced simulation techniques such as the discrete event simulation model, the agent-based model, system dynamics, and mixed methods are considered. Due to its characteristics, the mixed method is the most comprehensive approach. However, because mix methods have not been supported by proper tools or simulation software, agent-based model and system dynamics are proposed individually. Future research also should consider other than a market-based approach to develop robust policies to reach the ideal renewable energy share.
