High temperatures and severe drought across Europe this summer are affecting hydro, nuclear and solar power generation. Europe's hydropower output in the first seven months of this year was 20% lower than in the same period last year, while nuclear output was 12% lower, according to figures from Rustad Energy, a Norwegian consultancy.

Higher temperatures lead to higher evaporation and lower water levels in rivers, lakes and reservoirs, with hydropower bearing the brunt. In Italy, for example, hydropower accounts for 20% of the country's electricity production, but its output has plunged 40% in the past 12 months. Hydropower production in Spain plunged by 44%.

Fabian Loningen, an energy analyst, said that while hydropower production was volatile, the 40% drop was "very extreme" and not just in some regions, but in all of Europe's big hydropower countries.

Energy exporter Norway has warned that it may have to stop exporting energy to countries such as the UK if the country's reservoirs fail to recover.

Some hydropower industry experts say underinvestment in hydropower infrastructure and aging transmission lines are also contributing to the decline.

"We are going to have a problem this winter," said Eddie Ritchie, an expert with the International Hydropower Association. This should be a wake-up call [to us] to invest more in infrastructure in the coming years."

The drought has also affected nuclear power, particularly in France. Edf has cut production at several of its nuclear plants in recent days as warmer natural waters affect the water used to cool reactors.

Professor Sonia Senaviratne of ETH Zurich explained that if the water level in the river is too low and the water temperature is too high, the cooling of the reactor must be stopped, otherwise the discharged water will endanger the life in the river.

The French government on Friday tasked a crisis response task force to coordinate the work of various departments to deal with the drought. "This is the worst drought on record in France," said a statement from the prime minister's office.

High temperature weather is also not conducive to solar power generation, because the solar panel "afraid of sunlight", high temperature will lead to power loss of the panel, the service life is shortened.

Catherine Porter, a consultant at energy consultancy Wat-Logic, said the amount of electricity produced by solar panels drops significantly when temperatures rise above 25C and "everything works worse when temperatures are high".

Many users have a misunderstanding about solar power generation: they think that the stronger the sunlight and the higher the temperature, the greater the solar power generation.

In fact, high temperature will not only reduce the efficiency of solar power generation, but also affect the inverter and components.solar inverters and components themselves have negative temperature effects, and high temperatures may eventually cause their performance to degrade.

In the context of global warming, high temperature and drought may become the new normal not only in Europe, but also around the world.  Exploring efficient ways to use new energy is the key to Jntech's thinking and action.

Under the new situation,solar energy storage is very important. The solar energy storage inverter and system developed by Jntech control, store and invert the electric energy of solar modules and supply power to the load. The excess electricity is stored in the battery for insufficient light or for the load at night, and can be connected to the city Electric or diesel generators are used for hybrid power supply, and 24H uninterrupted power supply can be achieved according to the power configuration. The system has certain advantages in continuous power generation, energy storage capacity, energy storage cost, stability, safety, environmental protection and life.
