DHAKA, Sept. 20 (Xinhua) -- The Bangladeshi interim government's Chief Adviser Muhammad Yunus has underscored the urgent need for Bangladesh to transition toward cleaner, safer, and more affordable energy solutions as the country navigates a new path toward sustainable economic development. Yunus said Bangladesh, one of the world's most densely populated and climate-vulnerable nations, cannot afford prolonged reliance on fossil fuels, noting that the interim government has recently introduced a new national power policy aimed at accelerating solar energy adoption. "We will certainly explore these opportunities," he said. "But we need in-depth studies on these promising technologies. There is no question that Bangladesh must drastically reduce its dependence on fossil fuels."
