Overview
ABSTRACT
Wind energy is clean and renewable. The optimal use of this energy depends on a thorough knowledge of the wind resource and its main characteristics. Among the phases of the installation of a wind turbine or a wind farm, after a study of the operational constraints – weather, aerologic variables and air composition, etc. – the search for a suitable site is decisive. The article discusses how to choose a sloping plateau or hill, an even, clear surface at a sufficient distance from obstacles, in regions with prevailing winds with high energy potential.

INTRODUCTION
The global average growth rate for wind power has been 34% per year over the past five years. As a result, wind is not only the fastest-growing renewable energy technology, but also the fastest-growing source of electrical energy.
The cost of wind power has fallen considerably in recent decades. According to a study carried out by Eurobserv'ER in February 2017, installed wind power capacity worldwide at the end of 2016 was 486.7 GW; for the European Union it was 12.1 GW.
The two main obstacles to large-scale implementation of wind power are :
perceived wind intermittency;
the difficulty of identifying good wind spots, particularly in developing countries.
