The forecasted Hydro Power Gross Available Energy in Germany shows a gradual decline from 2024 to 2028, starting at 1.61 Million Tonnes of Oil Equivalent in 2024 and decreasing to 1.56 by 2028. Comparing this to the previous year's actual data—2023, which stood at 1.62—indicates a consistent downward trend. With a minor year-on-year reduction estimated between 2024 and 2025 by approximately 0.62%, the five-year Compound Annual Growth Rate (CAGR) further exemplifies an average annual decrease in hydro energy availability.

Future trends to watch for include:

Impact of climate change on hydroelectricity generation due to altered precipitation patterns.
Policy changes focusing on renewable energy expansion and their influence on hydroelectric investments.
Technological advancements in energy storage and efficiency that could mitigate declining hydro power outputs.
