Climate Change and Hydrovision

This is peer-reviewed book chapter second-authored by Dr. Basil Amuzu-Sefordzi in partnership with reputable researchers in Australia, China, and Ghana. The paper presents a feasibility study of using marine energy to combat climate change in Ghana.


The chapter highlights the climate change situation and the hydro-vision of the African continent. Much emphasis has been laid on the Ghanaian context with the design of a prototype (i.e., the design) of a novel marine energy conversion system that makes use of both wave and ocean current conversion techniques to generate electric power in Ghana. The feasibility of installing this conversion system in the Eastern Coastal Zone of Ghana, as well as its environmental and economic assessments indicates that Ghana possesses the potential, even with regard to the projected impacts of climate change. The coastal geo-morphology, seabed topography, and the local met-ocean patterns favor the implementation of this system. The economic appraisal shows that with the appropriate measures, Ghana could offset this endeavor. With the available modern technologies as well as the challenges confronting the national grid, the conversion system is designed to operate off-grid. Pursuing this endeavor is a worthwhile investment in the long term due to the gradual reduction of the electric power deficit in the country, low environmental impacts, potential economic dexterity, and the boundless source of marine energy.
