This study analyzes the factors that have facilitated Vietnam's recent rapid solar and wind power expansion and draws policy insights for other member states of the Association of Southeast Asian Nations (ASEAN).

A multi-criteria analysis is also pursued to provide an overall comparison across policy options.
