In 2023, Germany's geothermal power gross available energy stood at 458.53 thousand tonnes of oil equivalent. From 2024 to 2028, forecasts indicate steady growth, with a consistent increase in energy capacity. The year-on-year growth rates are commendably stable: 6.11% for 2024, 6.12% for 2025, 5.72% for 2026, and 5.39% for 2027. Over the five-year period, the compound annual growth rate (CAGR) is projected at 5.94%, reflecting a robust expansion in Germany's geothermal energy capabilities.

Future trends to watch for include:

Advancements in drilling and extraction technologies enhancing efficiency.
Government policies promoting sustainable energy that potentially accelerate growth.
Integration of geothermal energy into broader renewable energy portfolios facilitating stability and resilience in energy supply.
Increasing public and private investments in geothermal projects that support further capacity expansions.
