  • Calculation of Hydro Power REUK

    However hydro power turbine generators are very efficient when compared to wind turbine generators and solar panels. Efficiencies of around 70 can be expected which is to say that 70 of the hydraulic energy of the flowing water can be turned into mechanical energy spinning the turbine generator. The remaining 30 is lost.
