Treasurer Joe Hockey has attacked wind farms as “utterly offensive and “a blight on the landscape” in the latest sign that the Abbott government intends to cut back on renewable energy.

Mr Hockey told Macquarie Radio’s Alan Jones that driving to Canberra from Sydney meant he passed the Bungendore wind farm near Lake George on the NSW side of the ACT border.

“Can I be a little indulgent? I drive to Canberra to go to Parliament ... and I must say I find those wind turbines around Lake George to be utterly offensive,” Mr Hockey said. “I think they’re a blight on the landscape.”

Mr Hockey said he could not stop the wind turbines operating: "We can't knock those ones off because they're into locked-in schemes and there is a certain contractual obligation I'm told associated with those things."
