Record Heatwaves Put Pressure on Europe’s Energy and Safety

Central and eastern Europe are currently facing a period of extreme heat that has broken temperature records across multiple countries. This weather event is part of a longer, difficult summer that has caused widespread droughts and wildfires. As temperatures continue to rise, the region is dealing with the dangerous consequences of a changing climate, which is putting significant pressure on both energy systems and the safety of local populations.

According to The Guardian, several countries have recently registered their highest temperatures ever. In Slovakia, officials reported a new record high of 42 degrees Celsius in the town of Dolné Plachtince. Austria also saw record heat, reaching 41.2 degrees Celsius. These high temperatures are not just uncomfortable; they are causing major disruptions to critical infrastructure, specifically the power plants that provide electricity to millions of people.

One of the most serious problems is the lack of water needed to keep power plants running. Many power stations rely on water from rivers to cool their equipment. When river levels drop too low because of drought, these plants cannot operate safely. In Poland, authorities were forced to shut down the Kozienice and Połaniec coal-fired power plants because the Vistula River did not have enough water to cool them. This shutdown removed a large amount of electricity capacity from the Polish power system, creating a difficult situation for the country’s energy security.

Similar issues have affected other parts of the region. In Hungary, the Paks nuclear power plant had to be temporarily powered down due to low water levels in the Danube River. While the Hungarian prime minister, Péter Magyar, recently announced that one of the plant's turbines is back in operation, he warned that the country still needs to reduce electricity consumption. He noted that while water levels in the Danube have risen slightly, the situation remains fragile and dependent on future rainfall.

Beyond the energy sector, the human cost of this summer has been severe. The Robert Koch Institute in Germany estimates that approximately 11,900 people have died from heat-related causes across the country this summer. These figures have led to protests and calls for government action. In Germany, climate activists gathered outside the chancellery to demand an end to the use of fossil fuels. Annkatrin Schwirten, a representative from the group Fridays for Future Berlin, described the current situation as a result of irresponsible energy policies. She argued that society must not accept thousands of heat-related deaths as a normal part of every summer.

Environmental experts are also highlighting the connection between energy production and the climate crisis. Paweł Pomian, from the Polish environmental organisation EKO-UNIA, stated that power plants that contribute to climate change are increasingly becoming its victims. He suggested that the current crisis should serve as a wake-up call for all of Europe. According to Pomian, shifting toward wind and solar power is essential because these technologies require very little water to generate electricity, which would help protect both energy supplies and river ecosystems.

Meanwhile, the dry and hot conditions have created a high risk of wildfires across the continent. Data from the European Forest Fire Information System shows that about half a million hectares of land have burned across the European Union since the beginning of the year. Countries like Spain and France have been hit particularly hard, and a large area has also burned in Ukraine. The combination of heat, lack of rain, and strong winds makes it much harder for firefighters to control these blazes. In Austria, officials reported that the conditions for fires are currently more than twice as severe as any previous record for this time of year.

As the heatwave continues, the outlook remains uncertain. Governments are taking steps to manage the immediate crisis, such as the Polish prime minister’s request for employers to provide air conditioning and cold water for their staff. However, the long-term challenge of protecting people and infrastructure from such extreme weather is becoming more urgent. With climate experts warning that these events are becoming more frequent, the pressure on European nations to adapt their energy systems and improve public safety measures is likely to grow in the coming years.
