Based on the provided data for Sweden's hydro power energy supply, the forecasted values for the years 2024 to 2028 show a slight but consistent decline. In 2023, the value stood at 66.45 thousand gigawatt-hours. Starting from this baseline, the year-on-year variation shows marginal decreases: 2024 at -0.08%, 2025 at -0.08%, 2026 at -0.08%, 2027 at -0.06%, and 2028 at -0.08%. The Compound Annual Growth Rate (CAGR) over the last 5 years reflects a very modest negative trend, averaging a decline of around -0.08% per year.
Future trends to watch for include potential shifts in climate patterns, changes in water resource management policies, advancements in hydro power technology, and Sweden's energy mix policies, which might influence the overall efficiency and capacity of hydro power generation in the country.
