Wind turbines are usually shut down on days that the winds exceed 40 mph. It can be dangerous for the turbines to turn to fast.
If some turbines are spinning and some not, I suggest the only reason could be either defective units, or units undergoing maintenance. On days with decent wind, some turbines need to shut down. Not from the high wind but because the wind turbine company has agreed to provide a certain amount of power and when they have reached it there is no point in wearing out the turbines. There is usually at least one turbine on a farm that is being maintenanced at a time.
There are many possible reasons, however the most probable cause of a shut down turbine is "Overspeed". If the wind is too strong, the turbine can spin too fast and do severe damage to the gearbox and/or generator inside. There are systems that will automatically shut it down to protect it. Newer turbines can control the speed better, and will make adjustments to the blade pitch and yaw angle to avoid shutting down. If one of these is shut down, there may be another problem with it such as overheating components, etc.
It can only be used in windy parts of the country.

One problem with wind turbines is their visual impact on the landscape, as some people find them unsightly. Additionally, wind turbines can be a threat to birds and bats, as they can collide with the rotating blades. Finally, wind turbines are not always reliable sources of energy due to their dependence on wind availability.
They dont work if its too windy and have to be shut down
Well, its kind of obvisus to build one on a windy place for example: a hill, and some are built in the the sea. So mostly places where it is quite winddy, or where wind is likely to be.
It is very windy outside today.Scotland is a bit windy.
Most wind turbines are located in Australia as of 2010. There are many other places which use wind tubines but Texas is the main source. Wind turbines can be located anywhere there is enough room to place them and no danger to populace. The preferred locations are sufficiently windy and have largely constant winds, e.g. exposed high areas, like hills or small mountains or coastal areas, some wind turbines are even placed off the coast. The limiting factors in the placement of wind turbines are the price and ease of transport to that area, the infastructure of the area and assembling the turbines.

March 20-19 of 2010? Most days were mostly cloudy with some rain and wet snow. Some days were warm and sunny. It was quite windy on the 29th.
No. In fact, some wind turbines automatically slow or stop in dangerous winds.
bright, early windy, sunny.
In all power-generating schemes except solar, some other form of energy is used to produce electrical energy by turning a mechanical generator.
