Clean energy generated a record-high 44% of China’s electricity in May 2024, pushing coal’s share down to a record low of 53%, despite continued growth in demand.

The new analysis for Carbon Brief, based on official figures and other data that only became available last week, reveals the true scale of the drop in coal’s share of the mix.

Coal lost seven percentage points compared with May 2023, when it accounted for 60% of generation in China.

Other key insights revealed by the analysis include:

  • Monthly National Bureau of Statistics (NBS) data on generation by technology is now severely limited for wind and solar. For example, it excludes “distributed” rooftop solar and smaller centralised solar plants, capturing only about half of solar generation.
  • This mismatch becomes clear when comparing the NBS total for monthly electricity generation of 718 terawatt hours (TWh) with reported monthly electricity demand of 775TWh, according to the National Energy Administration (NEA). In reality, electricity generation must be higher than demand due to losses at power plants and on the grid.
  • Media reports have speculated that the record renewable capacity additions would have run into grid constraints in May, but the new data shows this is not the case.
  • China’s electricity demand in May 2024 grew by 49TWh (7.2%) from a year earlier.
  • At the same time, generation from clean energy sources grew by a record 78TWh, including a record rise from solar of 41TWh (78%), a recovery from earlier drought-driven lows for hydro of 34TWh (39%) and a modest rise for wind of 4TWh (5%).
  • With clean energy expanding by more than the rise in electricity demand, fossil fuel output was forced into retreat, seeing the largest monthly drop since the Covid 19 pandemic. Gas generation fell by 4TWh (16%) and that from coal by 16TWh (4%).
  • Falling generation from fossil fuels point to a 3.6% drop in CO2 emissions from the power sector, which accounts for around two-fifths of China’s total greenhouse gas emissions and has been the dominant source of emissions growth in recent years.

The new findings show a continuation of recent trends, which helped send China’s carbon dioxide (CO2) emissions from fossil fuels and cement into reverse in March 2024.

If current rapid wind and solar deployment continues, then China’s CO2 output is likely to continue falling, making 2023 the peak year for the country’s emissions.

Monthly mismatch

Every month, the NBS publishes data on China’s electricity generation by technology. The figures for May 2024 came out nearly a month ago, in mid-June, and were widely reported.

However, this data is increasingly limited because it excludes, among other things, “distributed” solar sites, such as those on the roofs of homes and businesses. Analysis for this article shows this misses out about half of the electricity generated by solar overall.

The fact that the NBS data on power generation is incomplete is obvious when looking at consumption numbers: the NEA reported electricity consumption in May was 775TWh, while the NBS reported generation at only 718TWh. In reality, generation must be significantly larger than consumption because of losses at power plants and in transmission.

The seemingly small amount of power generation from solar and wind reported by the NBS has caused confusion and has led to claims that the performance of wind and solar in China is poor.

The performance of wind and solar generation is tracked by “utilisation” data collected by China Electricity Council (CEC), showing actual output relative to the maximum potential. These figures are normally included in monthly statistics released by the NEA.

The NEA omitted this data from its May release, which led to speculation from Bloomberg and Reuters that the reason would be poor numbers for wind and solar. This proved to be largely untrue when the data became available directly from the CEC, with solar power utilisation increasing significantly and wind power utilisation falling, but within normal year-to-year variation.

Another dataset, tracking the fraction of solar and wind power wasted due to grid inflexibility, showed small increases of 0.8 percentage-points for solar and 1.7 points for wind. This is problematic for plant operators, but well short of a spike that would notably affect the utilisation numbers – they typically vary by more than 5% from year to year.

There is now enough data to work around the limitations in the NBS power generation data and give a complete picture of China’s power generation mix in May.

The first thing to note is that the NBS numbers are normalised to a 30-day month, which accounts for a fraction of the mismatch. The rest of this article uses normalised 30-day numbers.

Instead of using the NBS numbers, it is possible to estimate generation from solar and wind based on reported capacity and utilisation. Combining these estimates with reported generation for other technologies yields total generation of 783TWh and year-on-year growth of 8%.

Reported electricity consumption of 750TWh – when normalised to a 30-day month – is consistent with estimated generation of 783TWh, with the 4.2% difference being due to transmission losses.

Monthly data on transmission losses is not available, but the average for 2023 was 4.5%, matching closely with the difference between reported consumption and estimated generation.

Record results

Putting the various figures together shows that, far from the modest 29% year-on-year increase in the incomplete NBS data, there was a record 78% rise in solar generation in May 2024.

Installed solar capacity increased by 52% to 691 gigawatts (GW) and capacity utilisation improved from 16% to 19%. This delivered the largest increase in China’s electricity generation for any technology, with solar generation rising 41TWh from 53TWh in May 2023 to 94TWh in May 2024.

The second-largest increase was from hydropower, where capacity only increased 1%, but utilisation jumped from 31% to 41%, as the sector recovers from the record drought seen in 2022-23. This led to a 39% or 34TWh increase in power generation, which hit 115TWh.

Wind power saw a strong increase in capacity of 21%. Utilisation fell, however, likely due to month-to-month variations in wind conditions. As a result, power generation grew by a relatively modest 5%, or 4TWh, reaching 83TWh. Nuclear and biomass-fired power generation also saw small increases in capacity, but the utilisation of nuclear plants fell from 87% to 85%.

In total, clean power generation grew 78TWh, as shown in the figure below. This was more than enough to exceed the 49TWh increase in demand.

As a result, gas-fired generation plummeted by 16%, despite a 9% increase in capacity, driving a steep 24% drop in utilisation. Coal-fired generation capacity increased by 3% while power generation from coal fell 3.7%, resulting in average plant utilisation falling by 7%. Falling demand could temper investment in new coal capacity, which has run hot in the past two years.

The changes in coal and gas-fired generation, combined with a slight degradation in the thermal efficiency of coal-fired power plants, imply a 3.6% drop in CO2 emissions from the power sector.

After these changes in output, China’s power generation mix shifted significantly away from fossil fuels in May 2024. The share of coal-fired generation fell to 53%, down from 60% at the same time last year and the lowest share on record, as shown in the figure below.

Meanwhile, solar rose to 12%, up from 7% a year earlier and the highest on record. The remainder was made up of wind (11%), hydropower (15%), nuclear (5%), gas (3%) and biomass (2%).

Chart by Carbon Brief.

The overall non-fossil energy share was a record 44% and there was also a new record-high share for variable renewable – solar and wind – which reached 23%.

Solar and wind are gaining share in China’s power mix very rapidly, despite rising demand, as shown in the figure above. In May 2016, they accounted for just 7% of the total.

Meanwhile, strong clean-energy capacity growth continued in May 2024, with 19GW of solar being added, 3GW of wind and 1.2GW of nuclear.

In the first five months of 2024, China has added some 79GW of solar and 20GW of wind. These additions are up 29% and 21% respectively from last year’s numbers, which were already record-breaking, as shown in the figure below.

Looking at solar specifically, monthly additions in May 2024 were higher than the previous month of April and also increased year-on-year compared with May 2023.

The rapid growth in power generation from solar shows that the solar capacity boom is delivering new electricity supplies at a scale sufficient to cover much of China’s demand growth.

This reinforces the view that China’s CO2 emissions are in a period of structural decline.

If clean energy additions are kept at the level reached in 2023 and early 2024, then CO2 output is likely to keep falling, which would confirm 2023 as the peak year for the country’s emissions.

With China due to announce new climate targets by early next year, the government’s level of ambition for clean energy growth remains an open question.

About the data

Wind and solar output, and thermal power breakdown by fuel, was calculated by multiplying power generating capacity at the end of each month by monthly utilisation – the proportion of maximum possible output – using data reported by China Electricity Council through Wind Financial Terminal.

Total generation from thermal power, hydropower and nuclear power was taken from National Bureau of Statistics monthly releases. Monthly utilisation data was not available for biomass, so the annual average of 52% for 2023 was applied.

CO2 emissions from power generation were calculated by applying emissions factors from China’s latest national greenhouse gas emissions inventory, for the year 2018, as well as the monthly average coal power plant heat rate reported by National Energy Administration, and by assuming average thermal efficiency of 50% for gas-fired power plants.

Launch of Africa Energy Bank delayed again in blow to oil and gas hopes

Published

on

The launch of the Africa Energy Bank (AEB) has been put back yet again, raising doubts about the institution’s future ability to finance fossil fuel projects – its main objective – as global lenders retreat from such investments over climate concerns, experts told Climate Home News.

The bank, which had been billed to launch in September after a series of delays, is now scheduled to begin operations in November, according to the head of the African Energy Chamber, an advocacy body for the continent’s oil and gas sector.

Even as the world aims to transition away from fossil fuels, many African leaders have made clear they want to continue exploring and extracting the continent’s large oil and gas deposits – estimated at around 125 billion barrels of crude and over 600 trillion cubic feet of gas – to boost economic development.

As a group, Africa sided with a number of powerful oil-and-gas producing nations in blocking progress on negotiations to craft a global roadmap to transition away from fossil fuels at last year’s UN COP30 climate talks, although some countries did individually support the proposal.

    Meanwhile, major projects under development across the continent – including the 1,443-km East African Crude Oil Pipeline (EACOP) and Dangote’s 700,000-barrel-per-day Kenyan refinery – show that African governments see oil and gas as playing a significant role in meeting their energy and economic needs for many years to come.

    In 2022, at a gathering of the African Petroleum Producers’ Organization (APPO) in oil-rich Angola, ministers from its member states adopted a resolution to create the Africa Energy Bank to finance projects for the production, use and trade of oil, gas and broader energy sources.

    African control over energy resources

    An article on the APPO website explains that the bank was conceived as a way to overcome “disenchantment” with fossil fuels among “the international community” which it said had crystallised around the “energy transition” concept.

    “If Western countries, after having long taken advantage of the energy sources they now revile to develop, can afford the luxury of abandoning them, this is not the case in Africa,” it adds, noting that many of the continent’s economies are still largely dependent on oil and gas revenues.

    A separate web page about the bank, also hosted on APPO’s website, says its objectives include financing the exploration, production and refining of oil and gas, as well as supporting member states in transitioning from fossil fuels to cleaner energy sources “while ensuring energy security”.

    What’s on the climate calendar for October 2026?

    Said Addi, a former executive with Shell and energy commodities trading house Gunvor, said the new bank was judged necessary because financing for hydrocarbons from many traditional international lenders has become constrained.

    In trying to fill this financing gap, Africa is not simply setting up another fund to support oil and gas, he added. “It is also an attempt to give African countries greater control over how their energy resources and infrastructure are financed,” he explained.

    Nigeria to host the AEB

    The energy bank – a joint initiative of APPO and the African Export–Import Bank (Afreximbank) – has so far suffered several delays and is almost two years behind schedule. The initial plan was to start operations in January 2025, with Nigeria as the host country, but the bank’s opening was delayed to June of that year to allow Nigeria time to finalise the construction of the bank’s headquarters in Abuja.

    After the government announced the completion of the offices in late November 2025, a new launch date was set for January 2026, which was moved back to April, June and then September. Now it has shifted again to November, raising concerns that the institution may be losing momentum.

    Former Shell executive Addi said that if the capital is eventually paid in, the bank becomes operational and its first projects are commercially credible, then the delays will be regarded as normal teething troubles in setting up a multilateral institution. But, he added, scepticism will be justified if it continues to stall.

    Uganda may see lower oil revenues than expected as costs rise and demand falls

    Baron Lamarré, an oil and gas expert and former Petronas oil trader, said that missing “three deadlines in a row is not normal”, and warned that if the timeline slips again, “the story flips from ‘ambitious institution finding its footing’ to ‘good idea that lost momentum before it found any’.”

    The Nigerian government, APPO and Afreximbank did not respond to requests for comment by the time of publication.

    The funding challenge

    The Africa Energy Bank is targeting base capital of $5 billion, with plans to scale up to $120 billion within five years by mobilising private-sector funds. However, it is expected to start operations with initial seed capital of $500 million.

    The funding plan is to have the 18 member countries of the APPO contribute $83 million each to the bank as equity for a combined $1.5 billion. Afreximbank, other non-APPO African countries and investors outside the continent are expected to provide the remaining $3.5 billion.

    But even the initial $500 million has not been easy to mobilise. In May, APPO Secretary-General Farid Ghezali called on members to deliver on their pledges towards the startup goal before the end of June. But the delays suggest this may not have been met, with experts saying Africa may be finding it difficult to self-fund its oil and gas projects in the absence of international capital.

    Lamarré said every extension of the deadline points to the fact that “raising fossil fuel capital in Africa without the majors and their financing networks is brutally hard”.

    Why the global electrification agenda misses the point on Africa’s energy crisis 

    Since 2020, Western lenders, export credit agencies and insurers have been in steady retreat from African hydrocarbons, he said, while oil majors are divesting their African assets, handing over fields to smaller local operators whose credit ratings are not high enough to borrow cheaply.

    Even capital from China and the Gulf, which has partially filled the gap, cannot match the volume, tenor or pricing that Western investors once offered, Lamarré argued.

    “If mobilising the first $500 million of seed capital [for the AEB] has taken this long, that’s the clearest signal yet of how steep the climb to $120 billion looks,” he said, noting that the continent’s energy financing gap is as large as $30 billion-$45 billion per year.

    Africa’s investment landscape, meanwhile, has been shifting. While foreign direct investment dropped from a 2024 peak, inflows remained roughly one-third above the continent’s long-term average in 2025, according to the 2026 World Investment Report from UN Trade and Development (UNCTAD). They are concentrated in a few sectors including critical minerals needed for renewable energy technologies, battery manufacturing and advanced industrial production.

    At the same time, data on global energy investment from the International Energy Agency (IEA) shows that fossil fuel investment in Africa has declined over the last decade.



    “Trojan horse” for fossil fuels

    While the Africa Energy Bank struggles to get off the ground, climate campaigners have criticised its primary aim of financing oil and gas on the continent at a time when the world is starting to move away from high-carbon fuels to cleaner alternatives.

    Bhekumuzi Dean Bhebhe, founder of Africa Change Lab, described the bank as a “Trojan horse”, arguing that its focus on fossil fuel financing runs counter to the global energy transition and the African Union’s Agenda 2063 goals of sustainable development and inclusive growth.

    The energy bank, he warned, “risks locking Africa into a new cycle of debt, dependency and fossil fuel entrenchment”, adding that its financing blueprint does not pave the way for a climate-resilient future. “In truth, it is to deepen the same extractive, carbon-heavy pathways that the continent should be moving away from,” he added.

    Ugandan farmers use British court to try to stop East Africa oil pipeline

    Kenya-based climate and energy expert Joab Okanda said the AEB’s plan to finance oil and gas is “a misplaced priority” and it should instead back clean energy in line with the policies of some of Africa’s major export markets like Europe.

    In addition, the new bank could struggle to mobilise enough resources to advance large-scale oil and gas projects, he added, noting that its proposed $5-billion initial capital is equivalent to the cost of the East African Crude Oil Pipeline alone.

    The AEB’s aim of backing more fossil fuels should be flipped “to support countries that are oil-dependent to start working on their transition plans”, Okanda said.

    Factcheck: UK Conservatives double the ‘cost of net-zero’ after spreadsheet blunder

    Published

    on

    A booklet published by the UK’s opposition Conservative party includes a “cost of net-zero” that appears to have been doubled by a spreadsheet error.

    The “common sense” policy document argues that “what people ultimately want is a government competent enough to solve the problems for which it takes responsibility”.

    In a section that says “sophisticat[ed]…modelling” should not be a substitute for “political judgement”, the “Right Way” document disparages various estimates of the cost of net-zero.

    The Conservative document then claims – incorrectly – that the government’s official adviser, the Climate Change Committee (CCC), had put the cost of net-zero at close to £1tn. It says:

    “In 2020, the CCC estimated that its route to net-zero would cost £957bn.”

    In fact, the CCC’s 2020 estimate was exactly half this amount – £478bn – and last year it published a revised figure of £108bn, largely as a result of the falling cost of electric vehicles (EVs).

    Spreadsheet error

    The Conservative party’s erroneous claim appears to stem from another report that had accidentally added up numbers twice, using a spreadsheet published by the CCC in 2020.

    The 2020 spreadsheet contains a table listing the additional investments that would be needed to build a net-zero economy, from low-carbon electricity generation through to heat pumps and EVs.

    These extra capital expenditures, listed as “CAPEX”, add up to a total of £1.38tn over the 30 years of 2020-50. They are set against operational savings, listed as “OPEX”, of £0.90tn.

    Added up over 2020-50, the combined CAPEX and OPEX figures come to a total of £478bn.

    In addition to the annual sectoral CAPEX and OPEX figures, the CCC’s 2020 spreadsheet also has a line giving combined totals for each year. It appears that someone has added all of these numbers together, resulting in the savings and costs being counted twice.

    This double-counted total for the cost of net-zero amounts to £957bn – as shown in the image below – and it appears to be the source of the claim in the Conservative booklet.

    Screenshot of the Conservative parties' spreadsheet error

    At the time of publication in 2020, the CCC said that the £478bn net cost of net-zero amounted to less than 1% of GDP over 30 years – and that the large investment needed would not only result in savings due to lower fossil-fuel imports, but that it would boost GDP overall, by around 2%.

    In 2025, the CCC revised its estimates for investment costs and operating savings to £670bn and £562bn respectively, giving a net total of £108bn over 2025-50, or less than 0.2% of GDP.
