But this is against a weak comparative in 2013, which saw the first ever contraction in new capacity added when the figure fell to 35.7GW from 45.2GW in 2012.
GWEC's figures compare to 48GW in Windpower Monthly's recently published 2014 data which measures new online capacity rather than new installations.
According to GWEC, total cumulative capacity stood at 370GW at the end of 2014.
China retained its position at the top of the table, installing more than any other country. It accounted for 45% of the global market, with 23.4GW installed last year. India, with 2.3GW was a distant second in the Asian market, although GWEC said it believes the "stage is now set for a new round of market growth in that country".
The European market grew marginally in 2014, with 12.8W of new capacity, but this still fell short of 2012's record breaking year. Germany led Europe, with 5.3GW of new capacity. The UK was a distant second at 1.7GW. Sweden passed the 1GW mark for the first time, and France was the last of four European markets surpassing 1GW, with 1.1GW installed last year.
The US market recovered from 2013's low point with 4.9GW installed, while Canada set a new record of 1.9GW.
Brazil's 2.3GW in new capacity led Latin American installations of 3.7GW. Chile with 506MW and Uruguay 405MW also made strong showings.
