According to a study published in the US journal Science, use of wind power could reduce China’s CO2 emissions by 30% in the next 20 years.

By 2030 it is projected that China, which accounts for a major portion of global emissions, will need to double its current capacity by 800GW to meet energy requirements.

The study by Tsinghua University in China used meteorological data to assess China’s wind power potential, finding that wind power may be sufficient to satisfy the country’s imminent power needs.

The researchers behind the study proposed that China can generate 640GW from wind farms, provided they operate at 30% average capacity.

The proposal would potentially require $900bn (£539bn) investment, according to the study.

Coal accounts for nearly 80% of the country’s power needs and although many coal-fired power stations are being constructed to meet demand, the country is also focusing on renewable power.

China plans to construct seven major wind power bases in the next ten years and holds fourth place in terms of installed capacity at 12.2GW.

However, wind accounts for only 0.4% or 3GW of the country’s electricity.
