ABSTRACT
Background: Forestry operations require dependable energy for water pumping, seedling production, lighting, communication, staff facilities and community outreach. Remote forest stations and nurseries may face unreliable electricity, costly diesel use, and continued dependence on fuelwood. At the same time, biodegradable residues from kitchens, livestock units, and nursery operations remain underused. Solar-biogas hybrid systems offer a forestry-relevant pathway for reducing operational emissions while improving service reliability.
Objective: This review assesses practical opportunities for integrating solar photovoltaic and small-scale biogas systems into Kenya’s forest stations, tree nurseries, and adjacent community facilities.
Methods: A narrative synthesis examined literature and policy evidence on decentralized renewable energy, productive solar use, institutional biogas, organic-residue management, and low-carbon forestry operations in East Africa, with emphasis on applications compatible with Kenyan forestry settings.
Results: The evidence supports a complementary model in which solar systems power daytime loads such as borehole pumping, irrigation, office equipment, security lighting, and nursery infrastructure, while biogas supplies cooking and thermal energy where sufficient feedstock and water are available. Digestate can be safely managed as a soil amendment after quality assessment. Adoption is most feasible where institutions first conduct energy and feedstock audits, separate critical from flexible loads, train local operators, and budget for maintenance and battery replacement. Major risks include poorly sized systems, irregular feedstock supply, weak after-sales support, unsafe digester operation, and treating biogas as suitable for every site. Phased demonstration at high-demand nurseries and residential forest stations would generate evidence on cost, reliability, emissions reduction, and seedling-production benefits.
Conclusion: Solar-biogas systems can advance a just energy transition within forestry when designed around site conditions rather than technology promotion alone. Forestry agencies can lead by developing site-selection criteria, operational standards, staff skills, and monitored demonstration projects that connect clean energy with restoration delivery.
