flag China finishes world’s largest ultra-high-voltage grid, boosting renewables and cutting coal use.

flag China has completed the world’s largest ultrahigh-voltage power grid, with 41 lines transmitting renewable energy from western regions to eastern cities, supporting its electric vehicle and high-speed rail networks. flag Wind and solar provided over 25% of electricity in April, six years ahead of its 2030 target, but transmission bottlenecks have caused up to 10% of renewable capacity to go unused. flag Centralized planning enabled rapid construction, unlike in the U.S., though some rural residents report discomfort from static electricity. flag The grid expansion is key to reducing coal dependence and cutting emissions.
