4. ProcessFollowing Steps were Followed During the Thesis Development1- “Why wind energy”, “Increment of wind energy sector” and “Components of awind turbine” were explained.A- “Why wind energy” because sustainable, renewable and infinitive.B- “Increment of wind energy” can be seen in following figure.

5. Conclusion and Future WorksConclusion1- Site-Specific wind tower was designed.2- Model satisfied EU Standards.3- Door opening analyses was done and verified.4- Basic cost analyses was done.Future Works1- Instead of probabilistic method, optimization can be used.2- Big tower database can be created and used.3- More door opening types can be used.4- Cost estimation can be done more professionally.
