欧洲东部正面临严峻的电力危机，原因是多瑙河水位降至历史最低，严重影响核电厂的冷却用水供应。匈牙利总理马扎尔要求大型工业企业限制用电，因为供应全国逾四成电力的帕克斯核电厂将因缺水而首次被迫停机。罗马尼亚的切尔纳沃德核电厂也已关闭其中一座反应炉，迫使该国购买更昂贵的进口电力，临时总理博洛詹呼吁国民在尖峰时段节约用电。（关键数字：40, a second）
多瑙河流域多国均受到低水位的严重冲击。塞尔维亚最大的水力发电厂杰尔达普一号目前仅以三分之一的产能运转，八月几乎确定将实施供水限制。斯洛伐克布拉提斯拉瓦的多瑙河七月平均流量创下一百二十五年测量史上的最低纪录，大片河床裸露，部分河段的游船已无法通航。斯洛伐克的加布奇科沃水利工程八座涡轮机中仅一座在运行，水力发电量大幅下降。（关键数字：125）
今年夏天欧洲连续遭受热浪侵袭，不仅导致多瑙河与莱茵河等关键水道水位骤降，也引发致命野火并扰乱能源供应。法国同样被迫削减核电输出，因为河水温度上升可能威胁生态环境。摩尔多瓦作为欧洲最贫穷的国家之一，高度依赖从罗马尼亚和乌克兰进口电力，其能源部长警告多瑙河局势可能导致区域电力供应减少及价格上涨，尤其是在用电高峰时段。
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.
