Narrative:
Numerous windmills in area from north of avp to southwest of zerby. Currently we have use of nvgs. Without nvgs; the tips of the turbine blades are difficult to see at night. They extend far above the top of the towers. Many are sequentially lighted. Better illumination could provide a safer environment to pilots that do not have this equipment. Callback conversation with reporter revealed the following information: the reporter states that there are many wind turbines along the ridges in the area from north of avp west to the town of zerby. The turbines are continuously being added and many are not depicted on VFR sectionals. They are easy to see in daylight but difficult at night.
