A Systematic Review of Knowledge Spillovers from Renewable Energy Technologies (Rets) in Cameroon

Increases in the atmospheric concentration of carbon have significant adverse environmental and socio-economic implications, more so for developing countries with little climate-centric infrastructure. This paper investigates the salience of renewable energy in addressing climate risks and forming the basis of an innovation-centric growth model. It analyses the prevalence of knowledge spillovers in Cameroon using patents as a proxy for innovation and drawing from a broad-based international literature spanning. The study finds a propensity for knowledge spillovers, which occur from renewable energy to innovation due to learning-by-doing. Additionally, spatial distributions of knowledge clusters are found to result from the tacit circulation of technological information within and across industries. The paper finds the need for policymakers to prioritize climate-centric infrastructure to lessen environmental externalities and redress socioeconomic and regional imbalances. Meanwhile, second-round effects will incite cross-industry applications from Renewable energy technologies (Rets) and achieve broader development and socio-economic objectives ranging from poverty reduction, innovation, and sustainable economic growth.
