Bangladesh needs to transition from conventional energy sources to ensure its energy security and long-term sustainability in the near future. Given the supply chain disruption followed by the Ukraine crisis, energy security has become a major concern for developing and least-developed countries. As the sources are becoming scarce and prices are becoming volatile, these countries are finding it difficult to navigate without cooperation. In this context, cross-border energy cooperation and revitalizing the idea of the power corridor can help Bangladesh to mitigate energy shortage.
