Doesn't sound very ambitious. While Im not sure what exact numbers the 30% refers to, a comparable one might be 19.7% in 2024, which had grown by 9% in the 10 years from 2014. Another roughly 10% in 11 years would just be the same pace really.
But with current solar/wind deployment and the strong trend in EV-transition as well as a peak in coal consumption, this should accelerate significantly, anything less than 35% by 2035 seem highly unlikely.

China's first national offshore wind power test base is about to be put into operation, capable of testing the world's largest wind turbines and the longest wind turbine blades.​


it can carry out testing and inspection of the world's largest capacity wind turbines and the longest wind turbine blades, as well as international cutting-edge technology research in multiple fields.

At present, the testing base has entered the equipment testing stage and is expected to be fully put into use within this year .

This test platform is capable of testing wind turbine blades 150 meters or longer .

The drive chain test platform is used to test wind turbine engines and features six degrees of freedom loading technology. Simply put, it can apply pressure to the engine from six different directions, realistically simulating the complex and ever-changing offshore environment and thereby testing the engine's mechanical performance.

China's export of green tech beat America's export of fossil fuel in 2024 and the first 7 months of 2025.

China Is Beating the US in the Battle for Energy Export Dominance​

China’s exports of clean energy technology hit a record in August, with $20 billion shipped globally.
  • The US wants the world to buy its fossil fuels, while China wants to sell the world its clean energy technologies, with China currently being the clear winner.
  • China's exports of electric vehicles, solar panels, batteries and other carbon-cutting technology has been climbing for years, with exports hitting a record in August.
  • China exported $120 billion in green technology over a certain period, compared to the US's $80 billion in oil and gas exports abroad during the same period.

A common problem for wind turbines, especially offshore, is typhoon-proofing.

There are different ways to define a typhoon-resistant turbine. Nationally speaking, China has a

that guides companies to make "typhoon-type" turbines capable of withstanding wind averaging up to 198 km/h (123mph) for 10 minutes. On a global level, the

(IEC) – an organisation publishing international standards for electrical, electronic and related technologies – has developed guidelines for "typhoon-class" turbines expected to survive 205 km/h (127mph) wind for 10 minutes and gusts of up to 290 km/h (180mph) for three seconds.

On average, a Chinese offshore wind farm is projected to experience at least 100 typhoons during its designed lifespan, which is normally 25 years, according to a spokesperson at Goldwind, a Chinese wind turbine manufacturer.
