Ember's 'Major Countries and Regions' chapter of the Global Electricity Review 2026 profiles the seven largest power sectors—China, the United States, the European Union, India, Russia, Japan and Brazil, which together account for 72% of global electricity demand—ordered by their 2025 demand. It reports China's first fossil generation decline since 2015, EU wind and solar exceeding fossil generation for the first time, solar overtaking fossil in Brazil, and coal falling in India as renewables outpaced demand, while US emissions rose 3.1% on gas-to-coal switching.
