Untangling the crossed wires of China''s ''Super Grid''
"The ratio of wind over conventional energy is quite low, usually accounting for one-third of the mix," says Xu. He says that a new generation of UHV lines can, scientists theorise, handle solar and wind variability. But China''s only such line is being used to transport hydropower, and so the theory remains untested outside the lab.
