Firefighters were forced to cordon off a busy Sunderland road when a 55m-high wind turbine caught fire.
At the height of the blaze at the Nissan car plant eight crews from the Tyne and Wear brigade attended after receiving 190 calls from the public.
At first the crews feared that the structure would fall on to the nearby A19 and they set up a cordon.
The three-bladed turbine eventually fell into a nearby field and burned itself out.
Investigations are now under way to find out the cause of the fire.
Building work started on the £2m wind farm at the 750-acre site in September. The six turbines generate 7.5% of the factory's electricity.
