In 2025, the state of electricity consumption in Thailand is heavily reliant on fossil fuels, with more than two-thirds of its electricity generated from such sources. Gas alone represents more than half of the country's electricity supply, with coal making up almost 15%. Low-carbon energy sources contribute to roughly 14% of the total electricity generation. Solar and biofuels each account for a small slice, with close to none coming from hydropower and wind. The significant contribution from fossil fuels raises concerns on environmental sustainability due to their impacts on climate change and air pollution.

Is Electricity Growing in Thailand?

Unfortunately, electricity consumption per person in Thailand has seen a slight decline in 2025. The previous year's record of 3254 kWh per person has dropped to 3147 kWh, which is concerning given the growing need for electrification and modern technology. However, there is a positive note when it comes to low-carbon electricity, which has hit a new record with 436 kWh per person. This rise in clean energy generation highlights Thailand's potential to pivot towards a more sustainable electricity sector, yet the overall drop in electricity usage should be a call to action for further expansion and innovation.

Suggestions

To foster growth in low-carbon electricity, Thailand can learn from regions like Nevada and South Korea, which have successfully harnessed solar and nuclear energy, respectively. Nevada generates about 34% of its electricity from solar, showcasing potential for Thailand's sunny climate. South Korea, on the other hand, demonstrates the feasibility of nuclear energy, with this source providing 30% of its electricity. By emulating these examples, Thailand could effectively increase its solar and nuclear footprints, lessening its reliance on fossil fuels and paving the way for a future powered by clean energy.

History

Historically, Thailand's low-carbon electricity journey has been marked by varying developments across different periods. Throughout the late 1980s and 1990s, there were incremental successes in hydropower, although these gains were sometimes offset by periods of decline. Moving into the 2000s, hydropower saw intermittent growth, with biofuels making a significant yet fluctuating contribution in the mid-2010s. Recent years have shown promising growth in solar energy, especially with the notable increase of nearly 4 TWh in 2025, reflecting a pivotal stride towards a more sustainable electricity landscape. These trends indicate a considerable opportunity for Thailand to build on its solar prowess and potentially explore nuclear opportunities for long-term and reliable energy solutions.
