Classic windmills include a tail. At normal wind speeds it will face the windmill into the wind. During storms they need to be furled which will turn the windmill away from the wind.
The newer windmills are tailless and are motorized, and will also turn the windmill into the wind. They are probably more stable with shifting wind patterns and can be designed to be self furling.
Vertical axis windmills are not directional, and do not need to be turned into the wind. They will not show the direction of the wind.
Wind moves the blades in the direction that it is blowing.
The wind turbine/windmill has a generator inside of it, which converts the wind into energy!
The kinetic energy of the air molecules in the 'wind' is transferred to the blades of the windmill as kinetic energy of the moving blades of the windmill.

Wind moves the blades in the direction that it is blowing.
To measure the direction of wind, a wind vane can be an ideal tool. A windsock can also be used to measure the direction and strength of the wind.
If the wind is very fast and is going in one direction only!
Make a small prototype of a "Helical" windmill which is very simple and innovative if you can get a fabricator to work for you. And yes...a helical windmill is one which rotates(and in the same direction) irrespective of the wind direction.
Another name for a windmill is the wind turbine
If the windmill wouldn't swivel with the windflow, it would stop, then turn into the opposite direction :-) But fortunately wind usually not changes its direction of flow 180 degrees suddenly, so the windmill can swivel ... and continue running. Wind energy generators, which usually run autonomously, also adjust the pitch of the blades according to wind speed. Above a certain top wind speed, usually 25 m/s , they shut down, regardless of direction of flow.

No its work by wind...hence windmill.
Yes
It shows direction and wind speed in knots.
Wind speed effects how much energy a windmill produces. The faster the windmill goes, the more energy it produces.
