Global geothermal power capacity could nearly double within the next decade, with about 14 GW of new projects in development, according to Global Energy Monitor (GEM) Global Geothermal Power Tracker.

Improved permitting policies and technological advances are making geothermal a more viable baseload alternative to fossil fuels.

The US, Indonesia, the Philippines, and Kenya are leading expansion efforts, each planning to add over 1 GW.

In the US, faster permitting—reduced to about 28 days under a 2025 executive order—has accelerated stalled projects.

Geothermal is also gaining traction as a reliable energy source for data centres, with 1.4 GW already tied to power purchase agreements and major tech firms investing in projects globally.

Countries like Indonesia and the Philippines are aligning geothermal growth with sustainable data centre development.

Indonesia has particularly ambitious goals, targeting 22.7 GW by 2060 and rapidly shortening permitting timelines.

However, fast-tracked approvals have raised concerns about community displacement, environmental risks, and lack of consultation.

Experts stress that proper oversight, community engagement, and long-term planning are essential to avoid social and financial setbacks.

If managed responsibly, geothermal energy could support a just energy transition while reducing reliance on fossil fuels.
