The pace of China’s clean energy transition “is roughly the equivalent of installing five large-scale nuclear power plants worth of renewables every week,” according to a report from Australia’s national public broadcaster ABC (shared by long-time Slashdot reader AmiMoJo): A report by Sydney-based think tank Climate Energy Finance (CEF) said China was installing renewables so rapidly it would meet its end-of-2030 target by the end of this month — or 6.5 years early.
It’s installing at least 10 gigawatts of wind and solar generation capacity every fortnight…
China accounts for about a third of the world’s greenhouse gas emissions. A recent drop in emissions (the first since relaxing COVID-19 restrictions), combined with the decarbonisation of the power grid, may mean the country’s emissions have peaked. “With the power sector going green, emissions are set to plateau and then progressively fall towards 2030 and beyond,” CEF China energy policy analyst Xuyang Dong said… [In China] the world’s largest solar and wind farms are being built on the western edge of the country and connected to the east via the world’s longest high-voltage transmission lines…
Somewhat counterintuitively, China has built dozens of coal-fired power stations alongside its renewable energy zones, to maintain the pace of its clean energy transition. China was responsible for 95 per cent of the world’s new coal power construction activity last year. The new plants are partly needed to meet demand for electricity, which has gone up as more energy-hungry sectors of the economy, like transport, are electrified. The coal-fired plants are also being used, like the batteries and pumped hydro, to provide a stable supply of power down the transmission lines from renewable energy zones, balancing out the intermittent solar and wind.
Despite these new coal plants, coal’s share of total electricity generation in the country is falling. The China Energy Council estimated renewables generation would overtake coal by the end of this year.
CEF director Tim Buckley tells the site that China installed just 1GW of nuclear power last year — compared to 300GW of solar and wind. “They had grand plans for nuclear to be massive but they’re behind on nuclear by a decade and five years ahead of schedule on solar and wind.” Last year China accounted for 16% of the world’s nuclear-generated power — but also more than half the world’s coal-fired power generation, according to this year’s analysis from the long-running International Energy Agency. The IEA estimated that in 2023, China’s electricity demand rose by 6.4%, and they’re predicting that by 2026 the country will see an increase “more than half of the EU’s current annual electricity consumption.”
And yet in China “the rapid expansion of renewable energy sources is expected to meet all additional electricity demand…” according to the IEA analysis. “Coal-fired generation in China is currently on course to experience a slow structural decline, driven by the strong expansion of renewables and growing nuclear generation, as well as moderating economic growth.”
There’s also some interesting stats on the “CO2 intensity” of power generation around the world. “The EU is expected to record the highest rate of progress in reducing emissions intensity, averaging an improvement of 13% per year. This is followed by China, with annual improvements forecast at 6%, and the United States at 5%.”
