This paper applied the fishbone diagram as part of strengths, weaknesses, opportunities, and threats analysis related to the deployment of renewable energies in Cameroon. The results showed that the share of renewable energy in the country's energy mix decreased by 22.79%, from 98.90% in 2000 to 76.11% in 2015.This is attributable to the decline in hydroelectric generation and the increasing share of fossil fuels, as the country's potential for solar, wind and biomass remains untapped. Meanwhile, the under-exploitation of Cameroon's energy potential is mainly due to technological, financial, management, and the lack of skills barriers. However, the current rapid development of renewable energy technologies and financial support provided by the International Community under the Paris Agreement are opportunities that Cameroon can seize to engage significantly in R&DV, to promote its energy potential and reduce its dependence on foreign technologies. To this end, this paper provided some pathways through which policymakers should pay more attention.
