Based on the provided data, the gross heat production of anthracite in Germany is forecasted to remain stable at 747 terajoules per year from 2024 to 2028. There is no year-on-year variation, holding constant at the 2023 level.

Future trends to watch for:

Potential policy changes affecting coal usage in Germany, driven by environmental goals and energy transitions, could impact anthracite usage.
Technological advancements in energy efficiency and renewable energy sources might influence future demand for anthracite.
Global energy market fluctuations, particularly in coal demand and prices, should be monitored for their indirect impact on German anthracite production.
