Abstract Energy is one of the indispensable inputs for the survival of human being in the earth. Bangladesh has the very inadequate amount of indigenous non-renewable energy resources even which is being diminished rapidly to increase the electricity generation. Although the installed electricity generation capacity has been increased to 10,709 MW, still the amount is insufficient to meet the demand of the country. In addition to this, the insufficient power generation hinders the socio-economic and industrial development. This current problem in power generation of Bangladesh can be removed by incorporating renewable energy into electricity generation. Recently, utilization of renewable energy and Renewable Energy Technologies (RETs) is getting momentum in the country to achieve not only energy security but also to reduce environmental pollution and to limit the imminent depletion of the non-renewable energy resources. Overall, Bangladesh has the vast potential of biomass, solar, hydro, wind, and tidal powers. This paper outlines the present energy scenario of the country. Following this, the potential of available renewable energy resources is also reviewed and presented in this paper.
