“…In the case of Ethiopia, the process of transforming Ethiopia's industrial sector as the main driver, the government has an ambitious plan of boosting the contribution of the modern energy in the national energybalance to a significant portion by 2030, i.e., 22 GW from hydro, 7 GW from wind, and 1 GW from geothermal. This is in line with the ambition of becoming a middle-income country by 2025 [19][20][21]. Accordingly, the development of Eco-friendly forms of energy is increasing from time to time as indicated in Figure 1.…”

This research at supplying electricity to Ziway lake islanders in Ethiopia, through studying the wind, pumped hydro-storage (PHS), and solar energy potentials. A wind mast is erected, and measurements at 10,50, and 70m heights are taken for a year long. The wind is of class-4 with wind speeds of 7m/s at 50m, and 7.87m/s. The energy density is 318.8 kWh/m2 (50m). GIS-based 3D digital elevation model (DEM) is used to investigate the PHS, with the lake as lower-reservoir and a dried-out crater pond of an extinct volcano as upper reservoir. The head is extracted using optical remote sensing technology, DEM(LiDAR) 12.5m. Constraints considered are topography, area, head, and slope. Twelve upper reservoirs are identified within head range of 50-250,50-200, and 50-100m. The results showed a PHS capacity of 5976 KWh at head of 60m can be developed. The solar energy potential is 6.1KWh/m2 /day. The finding proved the viability of electricity supply to the community.
