Abstract: The sustainability of wind energy over Hexi corridor was explored by using the wind intensive observation data of stations and wind-towers during 1970-2004. Results show that the wind speed was generally stable in the period. It is projected based on the prediction of future wind speed and the unique geographic and humanistic environments that the wind speed will be still relatively stable before 2025, and the wind energy resource in the corridor has a good sustainability.

Key words: Hexi Corridor, wind energy, sustainability
