The environmental consequences of energy production has become a great threat to developing countries like Bangladesh. The country has faced a boom in energy capacity; 4 times larger in a decade; the majority of them are based on fossil fuels such as natural gas, oils, and coal. The existing reserve of conventional energy sources, environmentally harmful, are insufficient to meet the present and near future power demand. Besides, it is predicted that these reserves will be depleted very soon. All these presages that Bangladesh will face a catastrophic power crisis in the future. In contrary, Bangladesh is blessed with renewable energies like solar, wind, tidal, wave, and biomass energy. Research carried out by various researchers found that the country has great potential in renewable energies. This paper elucidates the opportunities and reliability of renewable energies in Bangladesh to ameliorate the power crisis.
