Construction of new coal-fired power plants across the world fell to their lowest level in a decade in 2018, with China accounting for nearly two-thirds of the fall, a new report said.
After peaking at 84 gigawatts of new capacity in 2015, coal project completions plummeted to 39 GW in 2018, demonstrating the steady progress in energy transition, said the report from Bloomberg New Energy Finance, or BNEF, a wholly owned unit of Bloomberg.
The report said that despite the spike in coal-fired generation, the pace of new coal capacity added to the grids in developing nations is slowing.
Zhao Changwen, director-general of the Department of Industrial Economy at the State Council's Development Research Center, said that energy transition is a medium-to long-term mission, and the fundamental driving force is technological progress.
China has been accelerating its clean energy shift by optimizing and improving its energy mix. Data from the National Bureau of Statistics showed that in the early years, raw coal accounted for 96.3% of total energy production while other types of crude oil accounted for 0.7%, and hydropower for 3%.
Over the past 70 years, the share of raw coal output has continued to decline, falling to 69.3% in 2018. The share of crude oil output steadily increased to 24.8% in 1976, and then gradually declined to 7.2% in 2018.
The proportion of natural gas output increased from 0.1% in 1957 to 5.5% in 2018. The proportion of primary electricity and other clean energy output surged from 3% in 1949 to 18% in 2018, according to the NBS.
Since the 11th Five-Year Plan (2006-10) period, with deepening energy reforms, energy consumption has been further controlled. Data from the NBS showed that from 2005 to 2018, the average annual growth of total energy consumption was 4.5%, 1.5 percentage points lower than the level between 1980 and 2005.
The growth rate of coal, petroleum and other traditional energy consumption slowed down. From 2005 to 2018, coal consumption grew at an average annual rate of 3.7%, and the average annual growth rate dropped by 2 percentage points from 1980 to 2005.
Xu Bin, a professor at China University of Petroleum, said that China's energy transition has been progressing steadily, thanks to technological advancement and the transformation of energy utilization.
He noted that in the next step, China should continue the transformation from resource-driven to innovation-driven. "The country should accelerate the improvement of independent innovation capabilities and industry technology standard leadership capabilities, and make innovation the driving force for development, in order to reduce renewable energy investment and operation and maintenance costs. It is necessary to do extensive research and forge important breakthroughs in core technologies."
