The potential health impacts of living near wind turbines will be the subject of further investigation by a New South Wales Parliament inquiry into rural wind farms.

Two further hearing days begin today at State Parliament to explore issues raised during regional hearings at Tamworth and Goulburn.

Inquiry chairman Greens' MLC Ian Cohen says his committee wanted more information on the health concerns.

"That's why we've undertaken to have a couple of more days of hearings and be able to really get into the different aspects of what are seen as impacts," he said.

"I'm not going to say whether they are or not at this point in time but certainly looking at both physical impacts and also psychological impacts."
