As the world's environmental focus shifts to China following the U.S. withdrawal from the Paris Agreement on climate change, Beijing's "green" energy targets are coming under increasing scrutiny.
While it is true that China is a global leader in renewable energy, with more capacity installed than anywhere else, a significant portion of this is going to waste. Curtailment -- the inability to use all the electricity capable of being generated at a given location -- was running at around 17% for wind energy alone last year.
