AB  - In many parts of Nigeria, wood remains a primary source of household and small-scale industrial energy. As fuelwood demand continues to grow, identifying species with high energy efficiency is increasingly important. This study evaluates eight commonly used wood species in Nasarawa State, Nigeria, to determine their suitability for fuelwood and charcoal production. Each species was assessed for calorific value, volatile matter, ash content, moisture content, wood density, and charcoal yield, using five replicates per species. Laboratory tests followed standard procedures, and the data were analyzed using descriptive statistics, ANOVA, and Duncan’s multiple range tests. Significant variation was observed across species, with Anogeissus leiocarpus, Khaya senegalensis, and Prosopis africana exhibiting superior energy profiles, including higher calorific values and lower ash and moisture contents.
