  "summary": "The annual synthesis of the whole series: nine variables, each at its latest reading. The 2026 headline is a contradiction: the climate has never been more demanding (2024 was the hottest year on record) yet solar has never been winning faster, becoming the largest single renewable at 8.7% of global electricity. Solar is scaling into exactly the climate that makes reading it correctly matter most.",
