Global wind energy capacity could increase by more than half over the next five years, as costs continue to fall and the market returns to growth at the end of this decade, a report by the Global Wind Energy Council has revealed.
In its annual report on the status of the global wind industry, the GWEC said cumulative wind energy capacity stood at 539 gigawatts (GW) at the end of last year, 11 percent higher than the previous year.
That should increase by 56 percent to 840 GW by the end of 2022 as countries develop more renewable energy to meet emissions cut targets and prices continue to fall, the wind industry association said.
Around 52.5 gigawatts (GW) of new wind power capacity was added worldwide last year, down slightly from 54.6 GW in 2016. The GWEC expects the market to be flat this year but start growing again from 2019.
“The annual market will return to growth in 2019 and 2020, breaching the 60 GW barrier once again and continue to grow, albeit at a slower pace, in the beginning of the new decade,” the GWEC said in its report.
“We expect to see total cumulative installations reach 840 GW by the end of 2022,” it added.
Wind power has become more competitive over the past few years, with a move from government subsidies to auctions which has brought costs down further.
“Overall, offshore prices for projects to be completed in the next five years or so are half of what they were for the last five years and this trend is likely to continue,” the report said.
China continues to be the biggest wind market in the world, adding nearly 19.7 GW of new capacity in 2017, though this was 15.9 percent lower than the previous year.
The pace of China’s wind development is gradually slowing down and growth is expected to be flat to 2020.
India experienced record wind installations last year, adding over 4 GW, but GWEC expects this to slow this year due to a transition period between old market incentives and moving towards an auction-based system, the GWEC said.
The European Union also had a record year in 2017 with 15.6 GW added. The bloc is expected to install around 76 GW of new wind power by the end of 2022, reaching a cumulative total of 254 GW.
The United States added 7 GW of new wind capacity last year. Despite attempts to change the structure of tax credits last year, the provisions remained intact and continue to support the industry.
