INVESTIGATING THE POTENTIALS OF ALGAE AS A RENEWABLE ENERGY SOURCE IN ABA NORTH AND OSISIOMA LGAS OF ABIA STATE, NIGERIA

This study investigates the potential of algae cultivation as a renewable energy source in Aba North and Osisioma Local Government Areas (LGAs) of Abia State, Nigeria, using a descriptive survey research design. Data were collected from 361 stakeholders—including residents, industrial operators, and government officials—supplemented by key informant interviews with community leaders, industry managers, and environmental officers. The study examined three objectives: (i) whether local resources such as wastewater and degraded non-arable lands are sufficient to support algae cultivation, (ii) the willingness of stakeholders to adopt algae-based energy projects, and (iii) the challenges that may hinder cultivation and utilization. Quantitative data were analyzed using SPSS version 28, employing descriptive statistics and one-sample t-tests, while qualitative data were thematically analyzed to provide contextual insights. Findings revealed that wastewater effluents and degraded lands in the study area are abundant and suitable for algae cultivation (mean = 4.36; t = 5.29, p < 0.001). Stakeholders expressed strong willingness to support algae bioenergy adoption (mean = 4.14; t = 3.97, p < 0.001). However, significant barriers were identified, including technical limitations, high capital costs, and weak regulatory frameworks (mean = 4.34; t = 5.37, p < 0.001). The study concludes that algae cultivation is feasible and socially acceptable in Aba North and Osisioma but requires technological innovation, financial investment, and policy clarity for large-scale adoption. Recommendations include integrating algae bioenergy into national renewable energy policies, fostering public–private partnerships for resource repurposing, initiating pilot demonstration projects, and expanding research on cost-effective cultivation and byproduct utilization. By situating algae bioenergy within the socio-economic and environmental realities of Abia State, the study provides practical insights for policymakers, industries, and scholars seeking to advance sustainable energy transitions in Nigeria.
