High temperature does not retreat, severe droughts are affected by European power production

According to Xinhua News Agency's high temperature this summer, the severe temperature and drought are severe, which affects hydropower, nuclear and solar power generation. Statistics of Norwegian consulting companies Lustad Energy showed that the amount of hydropower in Europe was 20%reduced compared with the same period last year, and nuclear energy power generation decreased by 12%.

High temperatures lead to the increase in evaporation of rivers, lakes and reservoirs, decreased water levels, and hydropower. Taking Italy as an example, hydropower accounts for 20%of the country's total power output, but the country has dropped by 40%in the past 12 months. Spain's hydropower production also dropped by 44%.

Energy analyst Fabian Langingen said that although the output of hydropower fluctuates large, 40%of the decline is "very extreme". Not only is the hydropower output decline in local areas, all European hydropower powers are not spared.

Energy exported countries Norway warned that if the water level of the country's reservoir cannot be rebounded, it may have to stop exporting energy to the United Kingdom and other countries.

Some experts in the hydropower industry said that the insufficient investment in hydropower infrastructure and the aging of transmission lines are also the reason for the decline in hydropower production.

The International Hydropower Association expert Eddie Ricci said: "We will encounter (power supply) in this winter. This should give us a wake -up bell, (remind us) increase infrastructure investment in the next few years."

Drought also affected nuclear power, and France was particularly affected. Many nuclear power plants in France have recently reduced production because of the high water temperature of natural waters at the moment, affecting the use of water for the cooling reactor of nuclear power plants.

Sonia Sona Varatner, a professor at the Federal Institute of Technology in Zurich, explained that if the water level of the river is too low and the water temperature is too high, it can only stop cooling the reactor, otherwise the discharged water will endanger river creatures.

On the 5th of this month, the French government instructed a crisis to respond to the work group to coordinate the work of various departments to deal with drought. The French Prime Minister's office issued a statement saying: "This is the worst drought since France records."

High temperature weather is also not conducive to solar power generation, because photovoltaic power generation boards are "afraid of sun", high temperature can cause power charts and shortened service life.

Catherine Potter, an energy consulting company Watt-Logic, said that when the temperature exceeds 25 degrees Celsius, the power generation of photovoltaic power boards has decreased significantly, and "when the temperature is high, everything is worse."
