The Chinese are on track to succeed in their bid to green their economy. Admittedly, they are continuing to open coal-fired power plants, but these are more flexible than the old ones and are designed to support renewable energies, explains economist Cédric Philibert in an interview with Le Monde . »
Cédric Philibert is a researcher who is fairly optimistic about the energy transition. An expert at the International Energy Agency for nineteen years, he published Climat. Les énergies de l’espoir (Climate: The Energies of Hope) (Les Petits Matins, 224 pages, €20) in October. According to him, the industrial choices made by China will accelerate the decarbonization of energy in that country, but also in others.
You predict an “avalanche” of greenhouse gas reductions, fueled by Chinese green technologies. Will the world’s biggest polluter save the planet?
What is certain is that if the biggest polluter does not clean up its act, we will not save the planet. The good news is that China has started to do so. This is the result of a strategy that began some fifteen years ago. Chinese greenhouse gas emissions plateaued eighteen months ago. We must be cautious, but it is likely that they will begin to decline even before China’s official 2030 target. And, at the same time, so will global emissions. By 2025, global solar energy production capacity will increase by around 650 gigawatts, more than 50% of which will be in China. One gigawatt is the power output of a nuclear power plant.
