# Renewable energy in China

The People's Republic of China is the world's top electricity producer from renewable energy sources. China's renewable energy sector is growing faster than its fossil fuels and nuclear power capacity, and is expected to contribute 43% of global renewable capacity growth. China's total renewable energy capacity exceeded 1,000 GW in 2021, accounting for 43.5 per cent of the country's total power generation capacity, 10.2 percentage points higher than in 2015. The country aims to have 80 per cent of its total energy mix come from non-fossil fuel sources by 2060, and achieve a combined 1,200 GW of solar and wind capacity by 2030. In 2023, it was reported that China was on track to reach 1,371 gigawatts of wind and solar by 2025, five years ahead of target due to new renewables installations breaking records. In 2024, it was reported that China would reach its target by the end of July 2024, six years ahead of target.
Although China currently has the world's largest installed capacity of hydro, solar and wind power, its energy needs are so large that in 2019, renewable sources provided 26% of its electricity generation—compared to 17% in the U.S.—with most of the remainder provided by coal power plants. In early 2020, renewable energy comprised about 40% of China's total installed electric power capacity, and 26% of total power generation. By 2021, it had grown to 29.4% of total power generation. The share of renewables in total power generation is expected to continue increasing to 36% by 2025, in line with China's pledge to achieve carbon neutrality before 2060 and peak emissions before 2030.
China sees renewables as a source of energy security and not just only to reduce carbon emission. China's Action Plan for the Prevention and Control of Air Pollution issued by China's State Council in September 2013, illustrates the government's desire to increase the share of renewables in China's energy mix. Unlike oil, coal and gas, the supplies of which are finite and subject to geopolitical tensions, renewable energy systems can be built and used wherever there is sufficient water, wind, and sun.
China is also a major leader of clean energy technology.$^{:98}$ As Chinese renewable manufacturing has grown, the costs of renewable energy technologies have dropped dramatically due to both innovation and economies of scale from market expansion. 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 has expanded 100-fold. However, China is not expected to achieve grid parity – when an alternate source of energy is as cheap or cheaper than power purchased from the grid—until 2022.
The country is the world's largest investor in renewable energy, with the country's companies accounting for four of the world's five biggest renewable energy deals made in 2016. In 2017, investments in renewable energy amounted to US$279.8 billion worldwide, with China accounting for US$126.6 billion or 45% of the global investments.

As of year end 2021 hydroelectric power remains by far the largest component of renewable electricity production at 1,340 TWh. Wind power provided the next largest share with 655 TWh, followed by solar at 327 TWh, subsequent to rapid growth from a low base of just 152 GWh in 2008. The overall share of electricity generated from renewable sources based on the figures in the above table has grown from a little over 17% in 2008 to a little over 27.7% by 2021. Solar and wind power continue to grow at a rapid pace.
By the end of 2019, the country had a total capacity of 790 GW of renewable power, mainly from hydroelectric, solar and wind power. By the end of 2019, China's hydropower capacity reached 356 GW. China's installed capacity of solar power reached 252 GW and wind power capacity was 282 GW, as of 2020.
By 2020, installed power for hydropower, wind, solar and biomass had increased to 385 GW, 299 GW, 282 GW and 35.34 GW, respectively.

## Sources
### Hydropower

As of 2020, China had more than 150 dams with generating capacity of more than 300 megawatts and installed capacity of 369 gigawatts.$^{:203}$
As of 2021, China operates four of the world's six largest dams.$^{:201}$ These include the world's biggest (Three Gorges Dam, with 22.5 gigawatts capacity) and second biggest (Baihetan Dam).$^{:201}$

### Wind power

China has the largest wind resources in the world and three-quarters of this natural resource is located at sea. Per its 13th Five-Year Plan, China aimed to have 210 GW of wind power capacity by 2020. It exceeded that goal, reaching 276 GW of onshore wind power by the end of 2020.$^{:33}$
China encourages foreign companies, especially from the United States, to visit and invest in Chinese wind power generation. However, use of wind energy in China has not always kept up with the remarkable construction of wind power capacity in the country.
In 2008 China was the fourth largest producer of wind power after the United States, Germany, and Spain. At the end of 2008, wind power in China accounted for 12.2 GW of electricity generating capacity. By the end of 2008, at least fifteen Chinese companies were commercially producing wind turbines and several dozen more were producing components. Turbine sizes of 1.5 MW and 2 MW became common. Leading wind power companies were Goldwind, Dongfang, and Sinovel. China also increased the production of small-scale wind turbines to about 80,000 turbines (80 MW) in 2008. Through all these developments, the Chinese wind industry appeared unaffected by the Great Recession, according to industry observers.
By 2009 China had total installed windpower capacity up to 26 GW. China has identified wind power as a key growth component of the country's economy.
As of 2010, China has become the world's largest maker of wind turbines, surpassing Denmark, Germany, Spain, and the United States. The initial future target set by the Chinese government was 10 GW by 2010, but the total installed capacity for wind power generation in China had already reached 25.1 GW by the end of 2009.
In September 2019, Norwegian energy firm Equinor and state-owned China Power International Holding (CPIH) announced their plan to cooperate in developing offshore wind in China and Europe.
In 2020, China deployed 71.7 GW of wind energy capacity, a 60% increase compared to 2019 and more than the rest of the world combined.
In the year 2022, China is set to install more 56 GW of wind turbines, of which 50 GW are from onshore wind and 6W from offshore wind turbines.
As of at least 2024, China has the largest domestic market for wind turbines.$^{:88}$
Although in some countries there are aesthetic objections to large-scale wind farms, in China they are often perceived as an aesthetic positive due to their associations with modernity and green development.$^{:119}$

### Solar power

China produces 63% of the world's solar photovoltaics (PV). It is the world's largest solar panel manufacturer as of at least 2024.$^{:88}$ It also has the world's largest domestic market for solar panels.$^{:88}$
Following the new incentive scheme of Golden Sun announced by the government in 2009, there are numerous recent developments and plans announced by industry players that became part of the milestones for solar industry and technology development in China, such as the new thin film solar plant developed by Anwell Technologies in the Henan province using its own proprietary solar technology. The agreement was signed by LDK for a 500 MW solar project in the desert, alongside First Solar and Ordos City. The effort to drive the renewable energy use in China was further assured after the speech of the Chinese President given at the UN climate summit on 22 September 2009 in New York, pledging that China would adopt plans to use 15% of its energy from renewable sources within a decade.
China has become a world leader in the manufacture of solar photovoltaic technology, with its six biggest solar companies having a combined value of over $15 billion. Around 820 MW of solar PV were produced in China in 2007, second only to Japan.
Following a report from China Renewable Energy Engineering Institute, in 2022 China is set to install more 100 GW of solar panels.
China's solar exports in 2022 grew by 64% to US$52 billion. Chinese exports mainly consist of solar modules, with Europe being the destination for 56% of the share of exports in 2022.
As of at least 2023, solar power in China is cheaper than coal-fired power.$^{:167}$
Although in some countries there are aesthetic objections to large-scale solar farms, in China they are often perceived as an aesthetic positive due to their associations with modernity and green development.$^{:119}$

### Biomass and biofuel

China emerged as the world's third largest producer of ethanol-based bio-fuels (after the U.S and Brazil) at the end of the 10th Five Year Plan Period in 2005 and at present ethanol accounts for 20% of total automotive fuel consumption in China. In the 11th Five Year Plan period (2006 through 2010) China planned to develop six megatons/year of fuel ethanol capacity, which is expected to grow to 15 megatons/year by 2020. Despite this level of production, experts say that there will be no threat to food security, though there will be an increasing number of farmers who will be "farming oil" if the price of crude oil continues to increase. Based on planned ethanol projects in some provinces in China, the output of corn would be insufficient to provide the raw material for plants in these provinces. In the recently published World Economic Outlook, the International Monetary Fund expressed concern that there would be increasing competition worldwide between bio-fuels and food consumption for agricultural products and that that competition would likely continue to result in increases in the price of crops.
Work has begun on the ¥250 million Kaiyou Green Energy Biomass (Rice Husks) Power Generating project located in the Suqian City Economic Development Zone in Jiangsu. The Kaiyou Green Energy Biomass Power project will generate 144 GWh/year (equivalent to 16.5 MW) and use 200 kilotonnes/year of crop waste as inputs.
Bioenergy is also used at the domestic level in China, both in biomass stoves and by producing biogas from animal manure. As of at least 2023, China is both the world's largest producer and largest consumer of household biogas, with more than 30 million rural households using biogas digesters.$^{:172}$

### Geothermal

Geothermal resources in China are abundant and widely distributed throughout the country. There are over 2,700 hot springs occurring at the surface, with temperatures exceeding 250 °C. In 1990, the total flow rate of thermal water for direct uses amounted to over 9,500 kg/s, making China the second direct user of geothermal energy in the world. Recognizing geothermal energy as an alternative and renewable energy resource since the 1970s, China has conducted extensive explorations aiming at identifying high temperature resources for electric generation. Until 2006, 181 geothermal systems had been found on mainland China, with an estimated generation potential of 1,740 MW. However, only seven plants, with a total capacity of 32 MW, had been constructed and were operating in 2006.

## National laws and policies

Chinese policies explicitly promote the use of clean energy as well as increasing the use of domestically manufactured technology.$^{:4}$ In the clean energy sector, China is a leading source of technology transfer to other developing countries.$^{:4}$ Since 2010 it has often led the European Union and the United States in clean energy investments.$^{:24}$ As of at least 2024, it is the world's leading energy financier.$^{:88}$

### Government bodies

After the dissolution of the Energy and Industry Department in 1993, China has been running without a government agency effectively managing the country's energy. Related issues are supervised by multiple organisations such as the National Development and Reform Commission (NDRC), Ministry of Commerce, State electricity Regulatory Commission (SERC) and so forth. In 2008, the National Energy Administration was founded under the NDRC, however its work has been proven inefficient. In January 2010, the State Council decided to set up a National Energy Commission (NEC), headed by then-Premier Wen Jiabao. The commission will be responsible for drafting a national energy development plan, reviewing energy security and major energy issues and coordinating domestic energy development and international cooperation.

### Policy history

China's Sixth Five-Year Plan (1981–1985) was the first to address government policy support for solar PV panel manufacturing.$^{:34}$ Policy support for solar panel manufacturing has been a part of every Five-Year Plan since.$^{:34}$
The Renewable Energy Law passed in 2005 explicitly states in its first chapter that the development and the usage of renewable energy is a prioritised area in energy development. The law established China's framework for regulating renewable energy.$^{:27}$ It also created four mechanisms designed to promote the development of China's renewable energy: (1) a national renewable energy target, (2) a mandatory connection and purchase policy, (3) a feed-in tariff system, and (4) a cost-sharing mechanism which includes a fund for renewable energy development.$^{:27}$
Contemporaneous with the Renewable Energy Law, China issued its Eleventh Five Year Plan.$^{:27}$ It sought to move China away from energy-intensive manufacturing and into high-value sectors.$^{:27}$ Every subsequent plan has done the same and, like the Eleventh, they have also highlighted the importance of low-carbon technology as a strategic emerging industry, particularly in the areas of wind and solar power.$^{:26–27}$ Likewise, the Twelfth Five-Year Plan also placed great emphasis on green energy. Detailed incentive policies and programs included the Golden Sun program, which provides financial subsidies, technology support and market incentives to facilitate the development of the solar power industry; the Suggestions on Promoting Wind Electricity Industry in 2006, which offers preferential policies for wind power development; and many other policies. Besides promoting policies, China has enacted a number of policies to standardise renewable energy products, to prevent environmental damage, and to regulate the price of green energy. These policies include, but are not limited to Renewable Energy Law, the Safety Regulations of Hydropower Dams, and the National Standard of Solar Water Heaters.
Several provisions in relevant Chinese laws and regulations address the development of methane gas in rural China. These provisions include Article 54 of the Agriculture Law of the People's Republic of China, Articles 4 and 11 of the Energy Conservation Law of the People's Republic of China, Article 18 of the Renewable Energy Law of the People's Republic of China and Article 12 of the Regulations of the People's Republic of China Concerning Restoring Farmland to Forest.
On 20 April 2007, the Environment and Resources Committee of the National People's Congress and the National Development and Reform Commission convened a conference on the occasion of the first anniversary of the Renewable Energy Law.
The Great Recession prompted significant stimulus efforts by China to invigorate its then-struggling solar industry.$^{:34}$
In 2009, China amended the Renewable Energy Law to improve the process through which renewable energy is connected to the power grid and distributed.$^{:217}$ These amendments also sought to address interprovincial equity in bearing to costs associated with developing renewable energy.$^{:27}$
Approximately 54% of the Belt and Road Initiative's energy projects are in clean energy or alternative energy sectors.$^{:216}$
President Xi Jinping has said China will reduce its CO2 releases per unit of gross domestic product by 65 percent from 2005 and hit peak CO2 levels by 2030. The country will hit carbon neutrality by 2060. That requires renewable energy consumption to rise to 25 percent and a corresponding increase in battery storage.

## Clean Development Mechanism projects in China

The Clean Development Mechanism emerged from the Kyoto Protocol as means for countries with Kyoto targets to purchase carbon credits resulting from costly emissions reductions in developing counties.$^{:30}$ China became the largest source of credits (i.e., Certified Emissions Reductions or CERs).$^{:30}$
According to the UNFCCC database, by November 2011, China was the leading host nation for CDM projects with 1661 projects (46.32%) of a total of 3586 registered project activities (100%). According to the IGES (Japan), the running total of CERs generated by CDM projects in China at 31 March 2011 was topped by HFC reduction/avoidance projects (365,577 x 1000t/CO2-e) followed by hydro power (227,693), wind power (149,492), N2O decomposition (102,798), and methane recovery (102,067).
According to the United Nations Framework Convention on Climate Change, of a total of more than 600 registered CDM Projects worldwide through mid-April 2007, there are now 70 registered CDM projects in China. The pace of Chinese CDM project registration is accelerating; prior to the beginning of 2007 China had 34 registered CDM projects, yet to date in 2007 another 36 Chinese CDM projects have been registered.
The Shanghai Power Transmission and Distribution Joint Stock Company, a subsidiary of the Shanghai Electric and Gas Group Joint Stock Company entered into a joint venture agreement with Canada's Xantrex Technology, Inc, to build a factory to design, manufacture and sell solar and wind power electric and gas electronics products. The new company is in the final stages of the approval process.
According to Theo Ramborst, the general manager and CEO of Bosch Rexroth (China) Ltd., a subsidiary of the Bosch Group AG, a world leader in controls, transmission and machine hydraulics manufacturing, Bosch Rexroth (China) Ltd. contracted €120 million in wind turbo generator business in China in 2006, a 66% increase year-on-year. Responding to the increase in wind energy business in China, Bosch Rexroth (China) Ltd. invested ¥280 million in October 2006 in plant expansions in Beijing and Changzhou, Jiangsu Province. Earlier in 2006 Bosch Rexroth started up its Shanghai Jinqiao (Golden Bridge) factory, which is involved in the manufacture, installation, distribution and service of transmission and control parts and systems; the Shanghai facility will also serve as Bosch's principal center for technology, personnel and distribution in China.

## Environmental protection and energy conservation

According to China's "Energy Blue Paper" recently written by the Chinese Academy of Social Sciences, the average rate of recovery of coal from mining in China is only 30%, less than one-half the rate of recovery throughout the world; the rate of recovery of coal resources in the US, Australia, Germany and Canada is ~80%. The rate of recovery of coal from mining in Shanxi, China's largest source of coal is approximately 40%, though the rate of recovery of village and township coal mines in Shanxi Province is only 10%–20%. Cumulatively over the course of the past 20 years (1980–2000) China has wasted upwards of 28 gigatons of coal. The same causes for a low rate of recovery in coal mining – that extraction methods are backward – lead to safety problems in China's coal mining sector. Another reason for the low rate of recovery is that the majority of extraction comes from small-scale mining; of the 346.9 gigatons of coal extracted by China, only 98 gigatons has come from large or mid-sized mines while 250 gigatons are extracted from small mines. Based on coal production in 2005 of 2.19 gigatons and a current rate of recovery of 30%, if China were able to double its rate of recovery it would save approximately 3.5 gigatons of coal.
On 13 April 2007, the Department of Science, Technology and Education of the Chinese Ministry of Agriculture hosted the Asian regional workshop on adaptation to climate change organised by the United Nations Framework Convention on Climate Change (UNFCCC). Climate change will affect Asian countries in different but consistently negative ways. Temperate regions will experience changes in boreal forest cover, while vanishing mountain glaciers will cause problems such as water shortages and increased risks of glacial lake flooding. Coastal zones are under increasing risk from sea level rises as well as pollution and overexploitation of natural resources. In 2006 in China storms, floods, heat and drought killed more than 2,700 people; effects ranged from drought in the southwest of China, which were the worst since records began to be kept in the late nineteenth century, to floods and typhoons in central and southeastern China. The weather events in China in 2006 were seen to be a prelude to weather patterns likely to become more common due to global warming. Topics discussed by representatives of Asian countries and developed countries, international organisations and nongovernmental organisations, included vulnerability assessments, implementing adaptation actions in various sectors of the economy and in specific geographical areas, such as coastal and mountainous regions.
Based on a recently completed survey in 2007, the Standardization Administration of China plans to further develop and improve standards for conservation and comprehensive use of natural resources in the following areas: energy, water, wood and land conservation, development of renewable energy, the comprehensive utilisation of mineral resources, recovery, recycling and reuse of scrap materials and clean production.
The IEA projected that China would contribute nearly 60% of global renewable energy capacity by 2030, with solar power driving 80% of the growth. Wind energy, particularly offshore, was also expected to expand significantly. While the global target to triple renewable capacity by 2030 was anticipated to be narrowly missed, renewable growth was still forecasted to surpass national goals.

## Energy production and consumption

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 CO$_2$, 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 nuclear, and 7.141% from other renewable energy sources, from 2.25%, 8.468%, 5.77%, relatively, in 2020. By 2023, the total non-fossil electricity installed capacity was over 50% of the total capacity installed in the country.
Chinese energy experts estimate that by 2050 the share of electricity from coal will decline to 30%–50%, and that the remaining 50%–70% will come from a combination of oil, natural gas, and renewable energy sources, including hydropower, nuclear power, biomass, solar energy, wind energy, and other renewable energy sources.
In 2018, transportation's share of energy consumption in China was 10.0%, consuming 436.2 million tons carbon equivalent, up by 7.6% in 2009 and 58.6 Mtce in 1995. The growth rate of the percentage, meanwhile, have seen a steady decline from 2010 to 2018, down from 10.8% to 3.5%.
According to a study by the Energy Research Institute of the National Development and Reform Commission on the economic circumstances of China's crude oil and chemical industry as of 2007, China has wasted an average of 400 million tons carbon equivalents annually. In 2020, China consumed 4.98 gigatons coal equivalents, up from 2.46 in 2006. According to Dai Yande, the chairman of the Energy Research Institute of the NDRC, while continued high consumption of energy is unavoidable, China must take steps to change the form of its economic growth and increase substantially the energy efficiency of industry and society. Among other things, China should find new points of economic development that move it away from being the "World's Factory" and improves energy efficiency. It also must avoid unnecessary waste, foster a sustainable economy and encourage renewable energy to reduce its reliance on petrochemical energy resources.
Since June 2006 when Chinese Premier Wen Jiabao visited the Shenhua Group's coal liquefaction project and expressed that coal-to-liquids production was one important part of China's energy security, there have been many new 'coal to oil' projects announced by many large coal producing provinces and cities. As of the end of 2006, 88 methyl alcohol projects were planned; their total was 48.5 megatons/year. By 2019, methyl alcohol output reached 69.9 megatons/year. This rapid development to build coal to oil projects prompted concerns about wasteful development and unintended consequences; these include wasteful extraction of coal, excessive water use (this process requires 10 tons of water for every ton of oil produced), and likely increases in coal prices.
China and Russia are linking their electric power networks so that China can buy power from the Russian Far East to supply Northeast China (Dongbei) and thus conserving domestic resources, lowering energy consumption, lessening China's dependence on imported oil (80%–90% of which must be shipped through unsafe waters), and reducing pollution discharge. Multiple long-distance high-tension, high-capacity line for international transmission have been built, including a 110kV transmission project, and three others with 220kV, 220kV, and 550kV. China also is considering connecting its power transmission lines with Mongolia and several former Soviet states that border China. Until 2020, Russia exported a total of 30.42 TWh electricity to China, decreasing coal consumption in the latter by 10.17 million tons. By importing electricity China not only reduced its dependence on imported crude oil, but also enhanced energy security by diversifying its foreign energy sources, making China less vulnerable to disruptions in supply.
In 2021 a total of 8571.4 TWh of electricity was generated in China, up from 7814.3 in 2020, from an installed base of 2380 GW of power generating capacity, 12.6% among which from windpower sources and 12.2% from solar sources.

## Challenges

There are significant logistical challenges to renewable energy in China. One such issue is grid connections from renewable energy power sources to the electricity grid. In recent years renewable energy developers have rushed to rapidly build wind farms, solar panels, and other power plants, which hasn't been synchronised with the time-consuming procurement of land permits to build grid connection. It takes more than twice as long to obtain the necessary permits and approval for the construction of high-voltage transmission lines and other grid connections as it does to obtain the permits and begin construction of power plants, creating a significant time lag.
Furthermore, even when connections have been built sometimes the grid still cannot absorb all of the electricity produced because the connections have voltage limits below what is being produced by many of China's renewable energy power plants, a phenomenon called curtailment. This issue of grid connection is especially true in regard to long-distance transmission of electricity. Most of China's wind and solar energy sources, and thus its renewable energy power plants, are located in the northwest of the country, while the highest electricity demand is in the southeast. However, there are limited high capacity transmission lines capable of transmitting the necessary amounts of electricity across that distance, leading to curtailments in the northwest and a need for fossil fuels in the southeast. The development of more long-distance, high-voltage transmission lines is necessary to maximising the use of the renewable energy that is being produced. Broader infrastructure initiatives like this can ensure the efficacy of renewable energy policy in China.
