Kiernan joins AWEA from the National Parks Conservation Association (NPCA), where he has been president since 1998.

Kiernan takes up his new post on 28 May. He replaces former CEO Denise Bode, who stepped down at the end of 2012, and interim CEO Rob Gramlich, who is currently in the top job.

Kiernan said: "With wind energy building over 40% of new electrical generation in the US last year, the massive public support for more renewable energy, and the recent extension of the Production Tax Credit (PTC) by Congress and the President, we have a unique opportunity to work together to make wind energy a more integral part of our national energy portfolio."
