China is the world's largest investor in renewable energy. In 2017, investments in renewable energy amounted to US$279.8 billion worldwide, with China accounting for US$126.6 billion or 45% of global investments.
China sees renewable energy as a source of energy security and a means to reduce carbon emissions. Unlike oil, coal, and gas, renewable energy systems can be built and used wherever there is sufficient water, wind, and sun. China is a major leader in clean energy technology, and as Chinese renewable manufacturing has grown, the costs of renewable energy technologies have dropped significantly. In 2015, China became the world's largest producer of photovoltaic power, with 43 GW of total installed capacity. From 2005 to 2014, production of solar cells in China expanded 100-fold.
China has also been transitioning to renewable energy sources such as wind, solar, and hydropower. Wind power is the second most crucial renewable energy source for China. From 2014 to 2023, the cumulative installed wind power capacity more than quadrupled to 440 gigawatts. From 2004 to 2022, domestic hydropower consumption increased more than threefold to over 12 exajoules. China is also a world leader in the manufacture of solar photovoltaic technology, with its six biggest solar companies having a combined value of over $15 billion.
China is also making significant strides in energy storage capabilities, such as pumped hydro storage and battery storage technologies, which are crucial for managing fluctuations in electricity supply and demand. China is on track to have at least 2461 GW of renewable electricity capacity installed by 2030, with solar capacity nearly tripling.

Coal is a major contributor to China's greenhouse gas emissions, and the country is the world's largest producer and consumer of coal and the largest user of coal-derived electricity.
China has been transitioning towards low-carbon sources of energy, such as nuclear and renewables, including hydropower, solar, and wind. In 2023, renewable energy sources accounted for 594.7 TWh of electricity generation in China, a year-on-year increase of 11.4%. This included 342.2 TWh of wind and solar power, a 27.8% increase from the previous year. China's total installed renewable electric generation capacity in 2023 was 1.26 TW, with 376 GW from wind power and 425 GW from solar power.
Despite the shift towards renewables, fossil fuels still provided 62% of China's electricity in 2024. China's per capita power sector emissions have risen, and the country is the world's largest coal mine methane (CMM) emitter. To address these emissions, China has implemented policies targeting gassy mines. By 2027, mines with high methane concentrations must capture or destroy the methane.
Natural gas is gradually replacing coal-fired capacity in some regions of China, particularly in the east, where power demand is higher, and the northeast, where stricter environmental regulations have been enacted. However, coal remains a critical fuel in China's electric power sector due to its abundant reserves and highly efficient coal fleet. China approved 5 GW of new coal power in the first half of 2021 and 46.1 GW of coal-fired power plant projects in 2020.
