A background on social context and renewable energy sources in Mozambique and Tanzania - An initial report from the STEEP-RES project

• This initial research report, appearing before the formal commencement of the STEEP-RESproject, focuses on the background and context of the project which is intended to make asocio-technical-ecological assessment of prerequisites to and effects of introducing renewableenergy sources (RES) into rural communities of the coastal Tanzania and Mozambique. Thereforea short review of the scientific literature is made dealing with societal prerequisites andrepercussions of electrification. Technical aspects related to the availability of natural resourcesand technologies for renewable energy resources utilisation are also briefly coveredalong with some very brief remarks on possible environmental repercussions.The review of the social context covers > 45 papers dealing with different experiencesof electrification in developing countries relating to renewable energy applicable for povertyalleviation in rural settings. The primary energy sources in rural East Africa are biofuels andelectricity plays a limited role. Electrification influences the composition of the energy mix,but during early development it has very limited impact on the use of wood for cocking andheating purposes. The institutional and financial frameworks are currently major barriers tosmall-scale RES-projects, although local technical and financial capacities are slowly increasing.Social and cultural settings create important drivers and barriers to introduction and diffusionof new technologies. Further, poverty and gender inequality are considered key issues forelectrification projects and create important barriers to success. Participatory and needorientedapproaches are considered necessary by most researchers for successful RES-projects.The more technical review is based on ~50 papers covers the existing renewable energysources (RES) - biofuels, solar, hydro, geothermal, wind, wave and tide. The technologicalstate and resource abundance of each source is discussed briefly in a regional context,along with environmental considerations on each technology.As large scale hydropower is being used in the region since long, it is noticeable thatsmall- and micro-scale hydropower is now advancing and will contribute to electrification inmany smaller river-bound areas. Bioenergy, in terms of firewood is widely used for cookingpurposes, although not environmentally sustainable and not with potential for electricity generation.Biofuels from plantations is rapidly increasing in Africa as well as the global trend.Also here, environmental considerations are of great importance for sustainability. Other RESof potential in the region, and with perhaps less environmental constrains, may be solar photovoltaicand tidal energy. Of less importance, according to regionally sparse resource abuniidance, seem to be wind and wave energy. The potential of geothermal energy is geographicallyrestricted to a few good locations.An inventory of actors within the field of East-African RES based on internet resourcesreveals a “top-heavy” information situation with many and well-designed information sourcesand active networks on global and African regional level while less web-information is availablefrom local levels in Tanzania and Mozambique, where only few companies working inthe field has been identified. More direct investigations are needed starting from the actorsidentified in this initial inventory.
