Renewable Energy Consumption: Thailand

Analysis# Thailand Renewable Energy Consumption Thailand's renewable energy consumption stood at 19% of total energy in 2021, representing a significant decline from its all-time peak of 33.5% in 1990. Over three decades, the country experienced a 43.3% drop in renewable energy's share of its energy mix, falling to its lowest point by 2021. This contraction reflects Thailand's rapid industrialization and growing reliance on fossil fuels to power economic expansion. The decline accelerated sharply after 2012, when renewables comprised 23.6% of consumption. By 2020, that figure had dropped to 20.9%, and fell further to 19% by 2021. The steady erosion across the 2010s suggests Thailand prioritized conventional energy sources to meet rising demand. The trajectory indicates continued pressure on renewable energy's market share unless policy interventions shift investment toward cleaner sources.
