Κλιματική αλλαγή

[Dimifoot]

Να σας βοηθήσω.
Υπάρχουν πολλά θέματα περίπλοκα, τόσο πολύ περίπλοκα που ενώ βλέπουμε λύσεις δεν είναι απλή η εφαρμογή τους.
Και δεν είναι μόνο σε θέματα πολιτικής ή οικονομίας, αλλά και σε δημόσια υγεία, διατροφή, καθημερινότητα.
Η λύση είναι απλή: όταν κάτι δεν έχει εύκολη και ξεκάθαρη απάντηση, το σωστό είναι πάντα και εξ ορισμού το αντίθετο από όσα λένε οι απανταχού MAGA, είτε είναι κυβερνήσεις, είτε είναι YouTubers.
Ορίστε, problem solved.

Heatwaves test Europe’s electricity system as air conditioning use soars


Record temperatures have also forced temporary shutdowns at power plants

Europe’s energy systems have come under intense strain this summer as repeated heatwaves have driven up demand for electricity and forced plants to pause production.

June was the hottest on record in western Europe, fuelling a rise in the use of air conditioning and prompting a sharp increase in electricity prices. Most parts of the region experienced at least two intense periods of heat in June and July, with some suffering more.

Total electricity demand in the EU during the two-week height of the June 23 to July 3 heatwave rose by 7.5 per cent year-on-year, according to figures from industry body Eurelectric.

Spain saw a 16 per cent increase during the same two-week period, when temperatures reached over 40C, Eurelectric said.

At the same time, the hot weather forced some nuclear power plants to reduce capacity or temporarily close, while hydropower also came under intense strain.

The barrage of heatwaves this summer marked a “massive change” for Europe’s energy systems, said Jan Rosenow, leader of the energy programme at Oxford university’s Environmental Change Institute.

Peak electricity demand has historically happened in winter in Europe, but as “summers get hotter at some point that might flip”, he said.

In the first few days of July, peak demand reached 1.5 terawatt hours in Germany, equal to the average demand in January, according to Ember, a think-tank. In Spain, demand during the heatwave exceeded the January average, at 0.83 TWh compared with 0.72 TWh.

Europe is warming faster than the global average. Scientists have warned of a rise in the intensification and duration of extreme weather events, including heatwaves, because of climate change.

In some countries, summer strains on the power system have had a dramatic effect.

On July 1, the Italian cities of Florence and Bergamo suffered major blackouts, as the country was reeling under a heatwave.

In Florence, hundreds of shops, hotels, restaurants, and homes were left without power for hours, as temperatures hit 40C. The blackout — which lasted until late evening — saw people stuck in elevators, forced the evacuation of a large department store, and led to many shops closing, as payment machines stopped functioning.

In Bergamo, officials were forced to install generators to restore some electricity, as repairs to the grid lasted several days.

Kristian Ruby, secretary-general of Eurelectric, said that grid operators were facing a “tough reality” and “need to be prepared”.

SSE, the UK power company, said generation from its hydropower plants dropped by 40 per cent quarter on quarter to the end of June, as Britain also grappled with heatwaves and severe drought.

Inland nuclear power plants across France and Switzerland temporarily suspended or reduced activity earlier in the summer, as it is harder to cool reactors in hot weather. In France, 17 out of 18 nuclear power plants faced capacity reductions during the June-July heatwave, Ember said.

Most inland nuclear plants rely on rivers to cool reactors and spent fuel, heating the water in the process before discharging it back. But with many rivers already hot, the plants could not discharge heated water without potentially damaging the river ecology.

Ember said there had also been concerns around the cooling of coal power plants, as well as fears about fuel shortages as lower water levels reduce barge carrying capacity.

When the EU’s multiannual budget from 2028 was published in July, EU officials said that new energy assets and infrastructure should be “climate resilient by design” to ensure they could withstand extreme heat and weather events.

However, solar generation reached a record high in June in Europe, up 22 per cent on the previous year, which Ember said kept the “grid well supplied during daytime hours” in most locations.

“The surplus of solar energy during the day helped prevent blackouts. However, the use of energy storage is still insufficient, leading to reduced energy supply after sunset. This translated into a sharp increase in electricity prices,” said Pawel Czyzak, Europe programme director at Ember.

It found that daily power prices doubled or even tripled in late June, reaching more than €400 per megawatt hour in Germany and more than €470/MWh in Poland.
