Wind energy, being probably the most promising renewable energy source due to its great energy potential
and applicability, concluded recently to a variety of impressive relevant structural applications. he most
common type to support on-shore wind energy converters is the cylindrical steel tower. Research on the
structural optimization of wind turbine towers is of great interest and importance due to their high
manufacturing and erection costs and certain transportation limitations that prevent them from reaching
greater heights. In order to increase the wind energy harvesting, the construction of taller structures and
the improvement of their structural detailing is critical towards achieving greater energy production along
with economy in material use and structural robustness. The present paper addresses the comparison of a
classic tapered steel wind turbine tower with a hybrid lattice tower of the same height and energy production
potential. Aiming to contribute to a better understanding of the structural behaviour of both types of wind
turbine towers, the research work focuses on the development of reliable numerical models along with the
use of analytical equations in order to predict accurately and interpret the aforementioned structural
response of the two towers by conducting a comparative study between them. The present study examines
the performance of each tower while attempting to minimize the total material used maintaining its
endurance and robustness.
