Wind power is leading from the front as a main source of new energy generation around the world, with $112.5bn invested last year alone and – as of 15 June, Global Wind Day (GWD) 2017 – over 500GW of turbines turning. 

The sector, which now employs 1.2 million people, making it one of the fastest growing industrial segments in the world, has become "a major driver" in the global energy transition, states Steve Sawyer, secretary general of the Global Wind Energy Council (GWEC), which this year has co-organised the Global Wind Day photo competition, Capture the Power of Wind, with industry body WindEurope.
