The largest contribution of the landmark 2015 Paris Agreement on climate change is that it mapped out the route toward the world's green, low-carbon transition, for which energy transition is of great importance, Xie said.
After three days of discussions last week in India on issues such as cutting emissions and fossil fuel use, as well as climate financing to support poorer nations, the group of major nations failed to issue a joint communique or deliver any new pledges.
The first phase of the solar and wind project, located in the Tengger Desert in the Ningxia Hui autonomous region is expected to generate 1.8 billion kilowatt-hours each year, equivalent to the power demand of 1.5 million households.
China commissioned 16.9 million kW of offshore wind power capacity last year, which accounted for over 80 percent of the world's total and pushed China's total installed capacity to 26.93 million kW.
Installed wind power capacity meanwhile rose 17.2 percent year-on-year to 340 million kW while that for solar power rose to 340 million kW, 25.8 percent higher compared with the same period the previous year, said the National Energy Administration.
