China is predicted to spend $1.8 trillion in the next 40 years to secure 1,000 GW of installed wind power capacity.

A new report called China’s Windpower Development Roadmap forecasts installed capacity of 200 GW by 2020 and 400 GW by 2030, culminating in 1000 GW by 2050.

Priority will be given to onshore projects up to 2020, after which attention will switch to offshore installations. By 2050 it is estimated that wind power will provide 17% of China’s total electricity production.

The roadmap was drawn up by the Energy Research Institute of China’s National Development and Reform Commission and the International Energy Agency.

Figures from the Global Wind Energy Council show that China’s investment in wind power rose by 28 per cent last year to $7.8bn, while total inland and coastal installed capacity reached 44.7 GW.
