Green Economics - China leads the global race in solar energy capacity

For all of the focus on China as the world's largest polluter, it might be worth reframing the problem to accept that it is also one of, if not the, largest innovator in this area.

China is leading the global renewable energy transition, with its wind and solar power projects under construction nearly doubling the combined efforts of the rest of the world. A report by Global Energy Monitor (GEM) reveals that China has 180 gigawatts (GW) of solar power and 159GW of wind power under construction, totaling 339GW. This positions China significantly ahead in the race to install renewable energy capacity, with the country on track to reach 1,200GW of installed wind and solar capacity by the end of 2024, six years ahead of its target.

China’s renewable energy boom is driven by strong government support and President Xi Jinping's emphasis on pivoting the economy towards technology and green manufacturing. This accelerated deployment is crucial for China’s commitment to reducing the carbon intensity of its economy and meeting climate targets. However, despite the rapid growth in renewables, China continues to approve new coal power plants, highlighting a paradox in its energy strategy.

China's reliance on coal is partly due to energy security concerns exacerbated by geopolitical tensions and power shortages. This reliance presents challenges in balancing the intermittency of renewable energy. Analysts suggest that improvements in energy storage and grid flexibility are essential for efficiently utilizing the increasing clean energy output. Notably, investments in lithium-ion batteries and grid-connected storage solutions are rising, reflecting China’s recognition of these needs.

The report underscores China's role as a global leader in renewable energy infrastructure, contrasting it with slower progress in other parts of the world. China’s capacity to turn planned projects into operational ones is unparalleled, with one-third of proposed projects reaching construction, compared to a global rate of 7%. This leadership raises questions about the efficiency and commitment of other countries in scaling up their renewable energy infrastructure.
