Ethiopia Energy Situation - energypedia.info

Energy SituationMarket SituationElectricity SectorKey Cross-Cutting Issues in The Energy SectorKey Problems of The Energy SectorPolicy Framework, Laws and RegulationsInstitutional Set-Up in The Energy SectorFurther InformationAbbreviations & NamesReferencesEthiopia has a final energy consumption of around 40,000 GWh, whereof 92 % are consumed by domestic appliances, 4 % by transport sector and 3 % by industry. Most of the energy supply thereby is covered by bioenergy, which in case of domestic use is usually stemming from unsustainable sources. The produced electricity of ~ 9000 GWh/a is mainly generated by hydro energy (96 %) followed by wind energy (4 %), whereof in total 11 % get exported. In contrast the major share of energy supply for transport is imported in forms of petroleum. Ethiopia is endowed with renewable energy sources. These include first of all hydro, but also wind, geothermal, solar as well as biomass. Only a small portion of the potential is harnessed today. Due to its fast economic growth the energy demand is increasing enormous. Therefore it is expected to rise by a rate of 10 -14 % per year till 2037. Today only 27 % of the population have access to electricity grid. This share is increasing due to an extension o...
