Over the period from October 2024 to September 2025, electricity consumption in the People's Republic of China showcases a diverse mix of energy sources. More than half of the electricity, approximately 58%, is generated from fossil fuels, with a dominant share from coal at around 55%. [1] China is the world's largest electricity producer. It overtook the United States in 2011 after rapid growth since the early 1990s. In 2021, China. . In the energy domain, there are many different units thrown around — joules, exajoules, million tonnes of oil equivalents, barrel equivalents, British thermal units, terawatt-hours, to name a few. The average coal plant in China ran for a r cord low 46. Put another way, China keeps adding idle new coal fired power capacity (to enhance flexibility and 487GW, up 16% yoy (see Figure 2 below).
