China's Coal Share Falls Below 50% as Renewables Surge

⚡ AI Executive Summary

China achieved a historic milestone in the first half of this year, with coal power dropping below 50% of total electricity generation for the first time. Renewable energy sources, particularly wind and solar, expanded rapidly to fill more than 40% of the grid's output, reflecting years of investment in cleaner generation capacity despite continued absolute growth in coal consumption driven by rising electricity demand. This shift carries profound implications for the global energy transition and carbon emissions trajectory. However, the rapid deployment of intermittent renewable sources is already straining China's transmission and distribution infrastructure, forcing curtailment of solar and wind output when the grid cannot absorb available supply. To sustain this momentum, policymakers are aggressively expanding grid modernization and battery storage—investments rising at double-digit rates—signaling recognition that infrastructure must evolve alongside generation capacity to prevent renewable waste and maintain reliability.
