Based on the provided data, the year-on-year percentage variations in surface production of brown coal in Germany are as follows:
- 2024 to 2025: -5.63%
- 2025 to 2026: -5.90%
- 2026 to 2027: -6.22%
- 2027 to 2028: -6.55%
The Compound Annual Growth Rate (CAGR) over the forecasted period (2024-2028) is approximately -6.08% per year.
The downward trend in brown coal production suggests a shift towards more sustainable energy sources. Factors to watch include policies for carbon neutrality, coal phase-out timelines, and investments in renewable energy infrastructure which will likely accelerate this decline.
