The extreme temperatures that have swept across Europe are putting great pressure on energy networks, significantly increasing demand for electricity and raising concerns about possible supply disruptions.

Meteorological forecasts show that temperatures in the Mediterranean region could reach up to 43 degrees Celsius this week, while countries such as France, Germany, Spain, Portugal, Switzerland and the United Kingdom are facing one of the hottest periods in recent years.

In France, more than half of the departments have been placed on red alert due to the risk of extreme heat, while authorities have called for maximum caution. In Britain, meteorologists warn that temperatures could reach up to 38 degrees Celsius in southern England, accompanied by tropical nights where temperatures do not drop below 20 degrees.

Rising temperatures have led to an increase in the use of air conditioners and other cooling devices, significantly increasing electricity consumption. According to the International Energy Agency, record temperatures are driving higher demand for energy, creating a major challenge for energy systems.

An analysis by Compare the Market reveals that Greece is the European country most exposed to increased energy demand during periods of extreme heat. Electricity demand in the country increases by 38.62 percent during the hottest months of the year.

Following Greece are Montenegro with 22.49 percent, Turkey with 21.91 percent, Croatia with 17.76 percent, Italy with 14.22 percent and Spain with 8.86 percent.

The study also shows that Hungary records the longest duration of power outages in Europe, with an average of 2.92 hours per year. It is followed by Slovenia with 2.16 hours and Greece with 1.63 hours.

Although rising energy demand poses serious challenges, experts say renewable energy is playing a key role in maintaining grid stability. During last year's heatwaves, record solar power production in the European Union helped cope with high consumption and avoid wider power outages.

According to the Ember organization, in Germany alone, solar energy covered up to 39 percent of electricity needs during the hottest days, demonstrating the growing importance of renewable sources for Europe's energy security./ CNA
