The forecasted geothermal power consumption in Germany's commercial and public services is expected to grow steadily from 2.58 thousand terajoules in 2024 to 2.81 thousand terajoules in 2028. This reflects an average annual growth rate (CAGR) of around 2% over these five years, indicating consistent investment and utilization in this sector. Given the data for 2023 is not available, we assume negligible fluctuations from 2024 predictions. The year-on-year increase from 2024 to 2025 shows a growth of approximately 1.9%, demonstrating an upward trend.

Future trends to watch for include:

Advancements in geothermal technology that may accelerate growth.
Policy changes and incentives promoting renewable energy use in Germany.
Investment levels in geothermal infrastructure and their potential impacts on consumption rates.
