China has maintained its leadership in the global race for new offshore wind turbine installations despite an expected decline in annually added capacity, according to the latest numbers from the World Forum Offshore Wind (WFO).

The WFO's annual report shows that nearly seven gigawatts of offshore wind capacity was added in China in 2022, a substantial drop compared to 12.7 GW of new capacity that was added to the national grid in 2021.

The plunge was attributed to the expiration of a favorable Chinese feed-in tariff, which

South Africa is one of the largest countries in Africa, the 25th biggest in the world, and currently ranked 31st among major economies and 99th in the list of the richest countries in the world..
