In 2020, 84.33% of Chinese primary energy consumption relied on fossil fuels, and 56.56% of it relied on coal, down from 70% in 2011. These energy production processes generated approximately 9.9 billion tonnes of CO2, up from 8.1 billion tonnes in 2010 and accounting for 30.9% of global emissions. In 2021, China produced 7.727% of its energy from hydroelectric, 2.32% from. But this new study shows that China is fast building up capacity to generate power from wind and solar, which could have a significant impact on limiting the impacts of rising temperatures. [pdf]
