    Identification of Potential Sites for Harvesting Wind Energy in the Town of Dessie, Ethiopia
    (Addis Ababa University, 2020-10) Yenenew, Mulugeta; Assefa, Tibebu (PhD)
    To find solutions for the global energy crisis, an analysis of a helical vertical axis wind turbine was conducted with the consideration of renewables and energy efficiency. Dessie town, one of the towns in the Amhara region, which uses different energy resources such as wood, charcoal, kerosene, animal dung, and hydroelectric power for heating, lighting, and transport. As the need for energy is increasing, the scratch for harvesting more energy sources is inevitable for cities and towns to be sustainable. This study was carried out in three steps: to map windy area in the town, the realization of the analytical calculation of a helical wind speed turbine power output which then informed the most wind harvesting potential sites. So, this study particularly aimed to address its use as the electricity supply for residential buildings or any other places with less ideal economic conditions. The easy and highly available mechanism using basic materials is to give individuals to have a viable option on their electricity production. Finally, based on findings, the study recommends wind energy could be a convenient planning strategy to inhabit and to supply affordable energy options for the growing urban population. The study also recommends proper energy regulations concerning alternative wind energy to improve, to achieve sustainability, and for the efficient utilization of wind energy.
