Abstract
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.
