Sustainable development is the main aim of developed countries in the world in order to meet the energy balance demand and emissions mitigation target in long term.

Currently, it has been being faced with the exhaustion of fossil energy resources such as coal, petroleum, etc… on the other hand, the combustion of fossil energy resources causes polluted environment accumulatively, therefore, it has to look for renewable energy resources to substitute for fossil energy resources in future. Wind energy resource will be chosen in future as mentioned in the energy policies of countries in the world where they have wind energy potential.
In just a few short decades wind energy has matured dramatically, making wind being one of the fastest growing sources of electricity in the world today. Due to technological advancements, policy initiatives, and economic drivers, wind energy is now able to make a cost-competitive contribution to our growing energy needs.
