UK records hottest day of the year as fifth summer heatwave reaches peak

Solar eclipses are far easier to manage than Europe’s cross-border electricity politics In the end, the solar eclipse did not cause the electricity grid to flicker. The early drop-off in solar generation was manageable, just as the National Energy System Operator (Neso), the state-owned body responsible for keeping the lights on, predicted. Gas-fired generators still had to be paid nose-bleed prices to fire up, and power via high-voltage interconnectors to continental Europe was also expensively sourced. But the system worked. A summer of heatwaves, however, has highlighted European grids’ reliance on those interconnectors – including seven between the UK and the continent – in an age of extreme weather and greater use of intermittent renewables. On Thursday, another low-wind “heat dome” day, a fifth of power to the British grid was coming from the continent at 10am. Cables from France alone were meeting 11%, or 3.54 gigawatts, of demand, or more than twice as much as the output at that time from the UK’s entire fleet of windfarms...

The drought roasting much of Europe this summer is taking a heavy toll on crops across the continent, from potatoes in the Netherlands to corn in Bosnia. Triodos, a Dutch bank with a focus on sustainability, has warned that this could reduce gross domestic product across the EU by 1 percent for 2026 – or around €180 billion.

From the Loire to the Danube, via the Rhine and the Po, European rivers are facing exceptionally low water levels. After a start to the summer marked by record temperatures, the drought is threatening river transport, energy production, ecosystems and water supplies.
