In the matter of clean energy, wind power is considered one of the most reliable and sustainable alternatives. Thanks to the progressed technology and diminishing expenses, its adoption has multiplied in the latest years. However, before the wind can become the most viable form of alternative energy, there are specific barriers we need to overcome. Conventional turbines have been known for their complex manufacture, expensive transportation, intermittence, and high maintenance cost. The vortex bladeless wind turbine (VBWT) is considered an advanced design that harvests energy from oscillation. This study investigates enhancing the electrical power production of VBWT through the optimization of VBWT design parameters by using the Taguchi design method.  Numerical results show that the produced power of the 20 meters long turbine is around three times greater in comparison to the initial VBWT output. The increase rate is 176% at a wind speed of 7 m/s. The power produced by the optimal turbine reached 3.44 KW, while the production of the initial VBWT was only 1.25 KW. The output power can be further maximized at an optimum external load. In the future, this study will be continued to enhance the overall performance of the bladeless wind turbine through the integration of the offshore wind turbine with tidal power.
