China’s solar-powered future

“Today, subsidy-free solar power has become cheaper than coal power in most parts of China, and this cost-competitive advantage will soon expand to the whole country due to technology advances and cost declines,” said Xi Lu, Associate Professor, School of Environment, Tsinghua University and co-corresponding author of the paper. “Our results demonstrate that the economic competitiveness of solar power combined with investments in storage systems could provide extra benefits for grid dispatch, which will be especially important for operation of future electric systems in China.”
