By Fidelis Eka Satriastanti, Tyler Roney and Soraya Kishtwari Dialogue Earth looks at Southeast Asia’s evolving landscape of solar energy adoption, from achievements to hurdles and future aspirations. Sunny Southeast Asia has made significant strides in solar energy, with solar farm capacity exceeding 20 gigawatts (GW) across ASEAN countries.

What is Southeast Asia's Energy Future?

Southeast Asia’s energy demand has surged over the past decade, driven by rapid urbanisation, economic development and population growth. The region stands at a pivotal moment for its energy future. With rapidly rising electricity demand, there is a narrow but vital window to shape a secure, affordable and sustainable energy future.

Which countries have the most solar power in Southeast Asia?

With abundant solar potential across the region, Southeast Asia has made initial progress in solar PV adoption, with over 35 GW installed at the end of 2024. Viet Nam has emerged as the regional leader in solar PV, representing 61% of the total regional capacity, followed by Thailand (11%) and the Philippines (10%).

What is Southeast Asia's energy potential?

Southeast Asia’s combined technical potential for utility-scale solar PV, onshore and offshore wind exceeds 20 terawatts. The region also has significant hydropower potential: Lao PDR produces more than 70% of its electricity supply from hydropower and is the largest clean electricity exporter in the region.
