The best way of measuring wind speeds at a prospective wind turbine site is to fit an anemometer to the top of a mast which has the same height as the expected hub height of the wind turbine to be used.
This way one avoids the uncertainty involved in recalculating the wind speeds to a different height.
By fitting the anemometer to the top of the mast one minimizes the disturbances of airflows from the mast itself.
If anemometers are placed on the side of the mast it is essential to place them in the prevailing wind direction in order to minimize the wind shade from the tower

Looking at nature itself is usually an excellent guide to finding a suitable WF site.
trees and shrubs (wind direction)
move along a rugged coastline (notice that centuries of erosion have worked in one particular direction)
Meteorology data, ideally in terms of a wind rose calculated over 30 years is probably your best guide,
Maybe wind turbines are already in the area
Large WTG have to be connected to the electrical grid (10-30 kV)
The electrical grid near the WTG should be able to receive the electricity coming from the turbine.
Both the feasibility of building foundations of the turbines, and road construction to reach the site with heavy trucks must be taken into account with any wind turbine project.
Pitfalls in Using Meteorology Data
Precision measurement of wind speeds, and thus wind energy is not nearly as important for weather forecasting as it is for wind energy planning, however.
Wind speeds are heavily influenced by the surface roughness of the surrounding area, of nearby obstacles (such as trees, lighthouses or other buildings), and by the contours of the local terrain.
