Abstract - Harvesting wind power has emerged as a
efficiency of the wind generator as the ratio of the generated output power and the maximum power available from the wind. The system in [12] used a commercial three-bladed turbine (16 cm radius), which provided 200 MW for a wind speed of 5.4 m/s (efficiency of 2.5%).
pivotal strategy in transitioning towards sustainable energy sources due to its abundant availability and eco-friendly attributes. This paper presents an overview of various methodologies and technologies employed in the harvesting of wind power, encompassing both onshore and offshore applications. It discusses the fundamental principles governing wind energy conversion systems (WECS), including aerodynamics, turbine design, and power generation mechanisms. Furthermore, it explores the advancements in wind turbine technology, such as horizontal and vertical axis turbines, as well as emerging concepts like airborne wind energy systems. The integration of wind farms into existing power grids, along with associated challenges and solutions, is also addressed. Additionally, the environmental impacts and socio-economic considerations associated with wind power deployment are discussed, highlighting the importance of sustainable practices in the renewable energy sector. Finally, the paper concludes with insights into future trends and potential innovations in wind power harvesting, emphasizing the need for continued research and development to maximize its potential contribution to global energy demands while minimizing its environmental footprint.
2. WIND OVERVIEW Wind is used to produce electricity by converting the kinetic energy of air in motion into electricity. In modern wind turbines, wind rotates the rotor blades, which convert kinetic energy into rotational energy. This rotational energy is transferred by a shaft which to the generator, thereby producing electrical energy. Wind power has grown rapidly since 2000, driven by R&D, supportive policies and falling costs. Global installed wind generation capacity – both onshore and offshore – has increased by a factor of 98 in the past two decades, jumping from 7.5 GW in 1997 to some 733 GW by 2018 according to IRENA’s data. Onshore wind capacity grew from 178 GW in 2010 to 699 GW in 2020, while offshore wind has grown proportionately more, but from a lower base, from 3.1 GW in 2010 to 34.4 GW in 2020. Production of wind power increased by a factor of 5.2 between 2009 and 2019 to reach 1412 TWh.Both onshore and offshore wind still have tremendous potential for greater deployment and improvement, globally.

1. INTRODUCTION – For that reason, these systems require energy harvesting from the environment for long term operation. Together with solar and hydro systems, the wind is a renewable energy source mostly used in large-scale systems. Many works have been proposed for solar small-scale energy harvesting. These systems incorporate methods for maximum power point tracking (MPPT) to charge batteries or super capacitors. Several studies suggest the use of wind energy for small-scale systems, mainly with vertical axis wind turbines. Most part of this work is based on the evaluation of the Savonius turbine. However, there are few examples for wind energy harvesting which include the turbine, the generator and a maximum power transfer circuit. To compare various wind prototypes, it is defined the
