The self water supply for cooling purposes in Germany's electricity sector is projected to decrease steadily from 4.99 billion cubic meters in 2024 to 2.38 billion cubic meters by 2028. In 2023, the volume was higher, marking a significant descending trend. From 2024 to 2025, the year-on-year decline is estimated at 13.4%, followed by an average yearly decrease of around 15.7% until 2028. This trend reflects a compounded annual growth rate (CAGR) of -17.4% over the five-year period.
Future trends to watch include advancements in cooling technologies, increased efficiency in water usage, and possible regulatory changes focusing on sustainability and reduction of environmental impact, which may further drive down water consumption levels.
