However, due to coal-dominated energy consumption mix, most of China's electricity has been generated from fossil fuels (particularly coal). According to Wind Database (2018), in 2015, 73.68% of electricity was generated from fossil fuels. As a result, power generation became an important source of China's CO 2 emissions.
