Extreme Heatwave and Low River Levels Force Energy Restrictions Across Europe

A severe heatwave has triggered record breaking temperatures and critical energy shortages across Europe, forcing Hungary and Romania to implement power saving measures. In Budapest, temperatures reached 41.6 degrees Celsius, breaking the absolute heat record for the city. The heatwave has caused the Danube river to reach record low levels, which has severely impacted energy production. Hungary was forced to largely shut down its sole nuclear plant because the facility relies on the river for cooling. In response, the Hungarian government switched off decorative and non essential lighting at major landmarks, including the Parliament building, the Buda Castle, and the Chain Bridge.

Romania has implemented similar measures to protect its only working nuclear reactor. Authorities in Bucharest dimmed street lighting by one third and turned off lights at museums and landmark buildings. Beyond energy concerns, the heatwave has caused significant health and environmental risks. Italy placed all its major cities on a red health alert, with temperatures in some northern regions reaching 42.8 degrees Celsius. In Bosnia, tourists sought refuge in the Vjetrenica cave to escape 40 degree outdoor heat. The environmental toll includes destructive wildfires in France and Spain, with estimated economic costs exceeding 15 billion euros.

Local responses to the energy cuts in Budapest varied. Some tourists expressed disappointment at the dark landmarks, while many residents supported the decision to ease pressure on the power grid. An associate professor from Eotvos Lorand University noted that the darkness actually benefits protected mayflies by reducing light pollution. In Budapest, Mayor Gergely Karácsony detailed further city measures to reduce energy and water use, including rescheduling high energy tasks and operating public transport in energy saving modes.
