Central Europe has seen record-breaking temperatures amid a sweltering heatwave, as energy and transport systems across the continent face disruption. The country’s only nuclear power plant is operating at 80 percent of its capacity as water levels in the Danube, Europe’s second-longest river, fall to record lows. The landlocked country is also being affected by low water levels in the Danube. Meanwhile, a worsening drought in Germany has forced several companies to transport cargo by road instead of ship, as water levels decline.
