歐洲東部正面臨嚴峻的電力危機，原因是多瑙河水位降至歷史最低，嚴重影響核電廠的冷卻用水供應。匈牙利總理馬扎爾要求大型工業企業限制用電，因為供應全國逾四成電力的帕克斯核電廠將因缺水而首次被迫停機。羅馬尼亞的切爾納沃德核電廠也已關閉其中一座反應爐，迫使該國購買更昂貴的進口電力，臨時總理博洛詹呼籲國民在尖峰時段節約用電。（關鍵數字：40, a second）
多瑙河流域多國均受到低水位的嚴重衝擊。塞爾維亞最大的水力發電廠傑爾達普一號目前僅以三分之一的產能運轉，八月幾乎確定將實施供水限制。斯洛伐克布拉提斯拉瓦的多瑙河七月平均流量創下一百二十五年測量史上的最低紀錄，大片河床裸露，部分河段的遊船已無法通航。斯洛伐克的加布奇科沃水利工程八座渦輪機中僅一座在運行，水力發電量大幅下降。（關鍵數字：125）
今年夏天歐洲連續遭受熱浪侵襲，不僅導致多瑙河與萊茵河等關鍵水道水位驟降，也引發致命野火並擾亂能源供應。法國同樣被迫削減核電輸出，因為河水溫度上升可能威脅生態環境。摩爾多瓦作為歐洲最貧窮的國家之一，高度依賴從羅馬尼亞和烏克蘭進口電力，其能源部長警告多瑙河局勢可能導致區域電力供應減少及價格上漲，尤其是在用電高峰時段。
Eastern Europe is bracing for electricity restrictions as the Danube River's water levels have plunged to historic lows, crippling nuclear power generation. Hungary's Paks nuclear plant, which supplies over 40% of the nation's electricity, faces its first-ever shutdown due to insufficient cooling water, prompting the prime minister to ask major industrial firms to curb consumption. In Romania, one reactor at the Cernavoda plant has already been shut down, forcing costly power imports, and a second reactor closure could occur at any time if water levels keep falling.
The crisis extends across the Danube basin, with Serbia's largest hydropower plant operating at just one-third capacity and water supply restrictions nearly certain for August. Slovakia's Danube recorded its lowest average July flow in 125 years of measurements, exposing vast stretches of riverbed and halting river boat navigation. While Slovakia's nuclear reactors continue operating thanks to cooling systems less dependent on river flows, hydropower output has dropped sharply, with the Gabcikovo Waterworks running only one of its eight turbines.
A succession of brutal heat waves across Europe this summer has strained vital waterways, disrupted energy supplies, and fueled deadly wildfires, with the Rhine River also on track to reach record lows. France has likewise been forced to curtail nuclear power output to prevent overheated discharge water from harming river ecosystems. Moldova, one of Europe's poorest nations and heavily reliant on power imports from Romania and Ukraine, has warned that the Danube situation could temporarily reduce regional power availability and drive up prices, particularly during peak hours.
