Vol. 4 No. 4 (2025): November 2025 Issue

The November 2025 issue of Future Energy Journal brings together diverse research spanning renewable energy integration, sustainable fuels, energy-market risk, solar power optimization, and nuclear energy systems. This issue highlights scenario-based pathways toward a 100% renewable energy future in Iceland, examining the integration of geothermal energy, biofuels, and electric vehicles, alongside an extensive assessment of waste cooking oil biodiesel and its potential contribution to sustainable transportation in Bangladesh. Complementing these renewable-energy studies is an analysis of risk and volatility in oil-dependent economies using advanced predictive analytics. The issue also explores innovative approaches to solar power generation by optimizing heliostat field design using the golden ratio and Fibonacci sequence. Finally, a neutronic and isotopic assessment of the NIRR-1 research reactor under alternative fuel-enrichment configurations provides insights into nuclear fuel utilization and reactor performance. Together, these studies reflect the broad and evolving dimensions of the energy sector, from renewable transitions and sustainable fuels to energy economics, solar technologies, and nuclear systems.
