The present chapter seeks to analyze the trend and growth of energy production, supply, growth, consumption and trade in South Asian countries based on data from 1971 to 2011 collected from World Bank data base, South Asia Development reports, Energy Outlook, ADB database. While India, Pakistan, and Bangladesh account for the major natural gas and coal resources, Bhutan and Nepal have large hydropower resources. The study suggests that South Asian countries need enhanced regional energy transfer to leverage economies of scale through a more vibrant intra and inter regional energy trade structure. Mobilizing financial resources to develop the necessary energy infrastructure is a major challenge to enhance energy security in the region. Therefore, South Asian countries need to develop policies that will attract investment in the region.
