The energy demand is expected to grow rapidly in most developing countries over the next decades. For Bangladesh, economic growth has been accelerating and it is expected that the population will grow from an estimated 162.20 million people in 2011 to 200 million by 2050, with almost half of the population living in urban areas. For meeting the expected energy demand as the population will rise and to sustain economic growth, alternative form of energy – renewable energy needs to be expanded. This paper tries to explore the possibility of finding the renewable energy mainly from micro hydro in different places of Chittagong hill tract region by thoroughly describing present condition of energy along with data collection, calculation and feasibility of power generation from July 2011 to Jan 2012.
