Solar energy is unlike Wind turbine generators and hydro power were an entire community can be dislocated or where large forest can be cleared for the project , destroying governmental projects and so on. During my undergraduate project work , a feasibility study was conducted to assess the potential of cascading the down stream of Kpong dam for hydro power generation. Though per my findings , the hydropower that could be generated was good enough but the environmental effects or implications were too much of which we did not consider it as a good idea to put up another dam under Kpong. The impact of solar energy is very minimal. If you have realised , a roof top can be used to install it . It is all about the correct angle of inclination of 15° .As for the feasibility, they are dully and fully aware remember it takes a number years to initiate it. Bui dam for instance was discovered in 1925 but it was initiated and completed in early 2000s. The thermal energy which we largely depend on aside the Akosombo is intermittent and also contribute hugely to global warming. Remember it runs on fossil fuel unlike solar which is clean , eco-friendly and renewable.
