Abstract

This study investigates the critical barriers to renewable energy adoption in Ghana, where reliable and sustainable energy access remains critical to achieving development goals and addressing climate change. Drawing from the existing literature, 44 barriers were identified and grouped into six categories: policy, institutional, economic/financial, structural/technical, political/legal/regulatory, and social. A two-round Delphi survey was implemented to gather consensus among 17 Ghanaian experts on renewable energy and climate change, resulting in 22 of the statements reaching consensus. A fuzzy synthetic evaluation (FSE) was used to rank these barriers based on their relative and overall importance in impeding the adoption of RE. The results show that policy, economic/financial, and institutional barriers are Ghana's main barriers to RE adoption. Key impediments include the lack of market-driven support, high commercial rates, and issues related to land litigation and availability. The study recommends regulatory and policy changes incorporating market-driven strategies and subsidies, and prioritising renewable energy in Ghana's power mix. Additionally, there is a need for training and awareness programmes to enhance social acceptance of RE sources.

采用德尔菲法和模糊综合评价法分析了加纳采用可再生能源的障碍

本研究调查了加纳采用可再生能源的关键障碍，在加纳，可靠和可持续的能源获取仍然是实现发展目标和应对气候变化的关键。根据现有文献，确定了44个障碍，并将其分为6类：政策、体制、经济/金融、结构/技术、政治/法律/监管和社会。为了在17名加纳专家中就可再生能源和气候变化问题达成共识，进行了两轮德尔菲调查，结果有22份声明达成了共识。根据阻碍可再生能源采用的相对重要性和总体重要性，采用模糊综合评价（FSE）对这些障碍进行排名。结果表明，政策、经济/金融和制度障碍是加纳采用可再生能源的主要障碍。主要障碍包括缺乏市场驱动的支持、高商业费率以及与土地诉讼和可用性相关的问题。该研究建议调整监管和政策，纳入市场驱动的战略和补贴，并在加纳的电力结构中优先考虑可再生能源。此外，还需要开展培训和提高认识方案，以提高社会对可再生资源的接受程度。
