Global investment acceleration

In recent years, we have observed dynamic growth in interest in geothermal energy, especially in developed countries. In 2024 and 2025, as many as 38 countries launched new projects related to deep drilling, heat storage, and increased efficiency of existing installations.

Key markets
  • Indonesia – leader in Asia, developing the world's largest geothermal field.
  • Iceland – a model district heating system based 90% on geothermal sources.
  • Turkey – the fastest-growing market in Europe, especially in medium-temperature geothermal.
Geothermal in state strategies

Many governments are introducing new regulations supporting RES development.

Examples: - subsidies for drilling, - geological risk coverage guarantee systems, - preferential loans and investment insurance.

Summary

Geothermal energy is ceasing to be a niche. Its global scale development indicates that it will become one of the pillars of energy security in the coming decade.
