Critical Review of the Challenges of Financing Renewable Energy Development in Sub-Saharan Africa

There is an acute shortage of electricity supply in Sub-Saharan Africa (SSA), and electricity blackouts are a common occurrence. Climate change and carbon dioxide gas emissions from conventional power-generating systems are also of great concern. Africa has vast renewable energy resources, including hydropower, solar,...

Wind energy in Australia: challenges and opportunities on the path to decarbonisation

Despite its status as an advanced economy, Australia grapples with a paradox: an economic reliance on fossil fuel and raw material exports that impedes its commitment to curtailing global climate change. This paper underscores the potential of Australia’s wind resources, comparable to those in the North Sea, as a trans...

From gas flaring to renewable flexibility: energy-adequacy-constrained decarbonization pathways for Iraq

Renewable-capacity planning can overstate decarbonization in a supply-constrained system because new clean generation may initially restore unmet electricity service rather than displace fossil output. This study develops a public-evidence-constrained, service-first planning framework for Iraq. Photovoltaic (PV), wind,...

Techno-Economic and Life Cycle Assessment of Modular Community Energy Systems for Renewable Energy Valleys

The transition to climate-neutral, resilient, and decentralized energy systems is particularly challenging for regions with strong seasonal demand, high renewable potential, and limited grid flexibility. Islands such as Crete exemplify these challenges. This work provides an integrated framework for evaluating both sys...

Biogas-Based Decentralized Power Generation for Rural Electrification

Reliable electricity access remains a major challenge in many rural areas due to frequent load shedding and limited energy infrastructure. As such, this study presents a decentralized biogas-based electricity generation system designed for rural communities using locally available organic waste. A community-based model...
