China's electricity grid remains major hurdle in its climate change ambitions ANI | Updated: May 20, 2021 23:04 IST Beijing [China], May 20 (ANI): After Beijing's surprise announcement that it would become carbon neutral by 2060, one of the most pressing challenges for China to meet its pledge to pivot towards renewables is overhauling its electricity grid that is the world's largest, say analysts and officials. China, the world's biggest electricity generator, power consumer and carbon emitter, has said that it is aiming for renewable power to account for more than 50 per cent of its total electricity generation capacity by 2025, reported South China Morning Post (SCMP).
