The Global Wind Energy Council (GWEC) and the European Wind Energy Association (EWEA) say wind power has become “fully mainstream” and cost-competitive, attracting $100bn in investment in 2014.

The groups are celebrating World Wind Day today, in conjunction with national wind power trade groups. Events include wind farm tours and information sessions in Canada, South Africa, Greece, Austria, Japan, Iran, Turkey and the UK.

Onshore wind power is now cheaper than conventional energy sources in an expanding number of markets worldwide, GWEC noted.

“Wind energy has become the favoured solution for large companies who need a reliable and consistent energy flow to power factories, operations and data centres”, said Malgosia Bartosik, acting CEO of EWEA, pointing to firms such as Apple, Microsoft, Ikea, Google, Lego, BMW, General Motors and Honda which “run their businesses increasingly on wind power”.

“As businesses become increasingly aware of the progress in technology and falling costs we are seeing a rapid change in investment patterns,” said Steve Sawyer, Secretary General of the Global Wind Energy Council.
