Book excerpt: With South Asia's growing energy demand, governments in the region are facing the short-term pressures of facilitating energy access, while attempting to formulate long-term sustainable strategies. This book explores how the key economies of South Asia are addressing issues such as the diversification of energy consumption profiles and import sources, investments in renewables, enabling universal energy access, challenges to regional energy cooperation, greenhouse gas emissions and climate change, and the policy changes that can foster bilateral and multilateral action.As governments seek to ensure access to affordable, reliable, secure, sustainable and modern energy, trends and drivers are emerging and shaping the South Asian energy landscape. The first section of the book examines energy trends at the regional level, while the second section focuses on the internal and external challenges faced by India — the largest energy consumer in the region and the third-largest energy consumer in the world.The diverse perspectives in this volume provide a holistic snapshot of South Asia's ongoing low-carbon energy transition, and highlight the importance of the region working collectively to navigate the many obstacles.
