Wind power could supply as much as 20% of the world's total electricity by 2030 due to dramatic cost reductions and climate-change targets, according to a report by the Global Wind Energy Council. Total wind-power capacity could reach 2,110 GW, annual investment will rise to €200bn ($224bn) and result in a carbon-dioxide emission decrease of more than 3.3 billion tonnes per annum. The report, which was released on Wednesday, also said that wind energy is already cheaper than other forms of renewable energy. However, curtailment, or wasted power, was a major challenge for the country, but tackling transmission bottlenecks would help reduce the current level from 21%.

It estimated that China, already the world's biggest builder of turbines, will quadruple its current capacity to 666.5 GW.
