Hayes is replacing Charles Hendry, who held the portfolio for the last two years in the Coalition Government.
Commenting on the appointment, RenewableUK director of external affairs Jennifer Webber drew attention to Hayes vast experience.
"We know that he already appreciates the importance of providing the right training for the skilled workforce of the future.

Webber also commended the work of the outgoing Minister Charles Hendry, lauding his work in setting up of the Offshore Wind Cost Reduction Task Force.
