The development and monitoring of RET for the past decade has been possible largely through global programmes of research and development, demonstration (RDD) and financial incentives, most especially in the developed countries. The two Nigerian Energy Research Centres on Renewable Energy as well as other individuals and research groups in the institution of higher learning involve in similar research work had achieve little in the area of innovation and local manufacturing of RET. This was based on the lack of credible R&D Infrastructure for adopting and modifying imported RET and drive applicable business models. If Nigeria is to optimally benefit from the application of RET, it must have credible funding of research and collaborative research between industry and academia and commercialisation of R&D output.
