Post-2018, the values showed a declining trend, apart from minor fluctuations in 2020 and 2021, arriving at the 2023 value of 2.55 Million Tonnes of Oil Equivalent, down slightly by 0.37% from the previous year.
Forecasts from 2024 to 2028 predict a steady decline at a compound annual growth rate (CAGR) of -0.29%. The energy availability is expected to gradually decrease, forecasting a figure of 2.50 Million Tonnes of Oil Equivalent by 2028, reflecting a 1.45% reduction over five years.
Future trends to watch for include technological advances in hydro power efficiency, climate change impacts on water availability, and policy shifts toward renewable energy sources.
