Heatwaves will trigger net zero meltdown

Experts warn that net zero technologies could fail during heatwaves, posing risks of breakdowns and power cuts. A report highlights that heat pumps, electric cars, and solar panels may need to be turned off in temperatures exceeding 27C. Solar panels lose efficiency in high heat, impacting power generation.

Heat pumps, set to be standard in new homes by 2027, increase future electricity demand for cooling. The report predicts higher cooling demand alongside decreased solar output, risking electricity shortages and rolling blackouts. Electric vehicle batteries also degrade in heat, presenting safety concerns.

Despite these warnings, government aims for renewables like nuclear continue, though high temperatures may affect output and cooling. Michael Kelly from Cambridge University argues the report lacks real-world examples and validation.
