Renewable energy plays a vital role in sustainable development by increasing human development and economic productivity. Analysis of the pipeline of installed wind farms across Africa shows that the continent has significant wind resources and has the potential to increase its capacity by more than 900 percent through the addition of 140 planned projects. The design and implementation of a renewable energy system for wind turbine power analysis in the Aykot Akpaden community serves as a valuable example of the effectiveness of wind energy in reducing high-carbon greenhouse gas emissions and other environmental pollutants and is beneficial to the present and future environment. This analysis evaluates the wind speed and its significant power output based on the system design parameters used. The experiment is carried out between 8:00 am and 9:00 pm for 7 days. The results show that the wind speed in the Akpaden area varies between 2.67 m/s and 4.57 m/s with an average wind speed of 4.03 m/s. There are limitations in some hours of the day when there is no significant wind speed, but there is no full 24 hours a day without the free flow of wind energy. Using a wind turbine with a minimum swept area of ​​0.283 m2, the output power generated by the available wind speed varies from 3.0 W to 8.82 W/s, so there is 78% efficiency in the system design compared to the theoretical output power of 11.32 W using the system design parameters. Also, as shown in the graphical diagram, there is a significant drop in the output power between 3:00 PM and 4:00 PM which is due to the decrease in the wind speed of the area at that time. Therefore, it is observed that there is useful power in the wind speed of the study area which, after being collected and stored, can be used as useful energy for the students during their experiments and research. The output power of the wind turbine can be improved by the desired percentage by using a turbine with a larger blade radius and swept area.

Wind energy is one of the most important resources for generating electricity and is used extensively throughout the world among the different renewable energy sources, including solar, wind, hydro, geothermal, biomass, and ocean thermal power [1]. Due to its many benefits, wind energy is one of the energy sources with the quickest rate of growth in the world [2]. Researchers are tackling technical and socioeconomic issues to promote a future with decarbonised power in order to maximise its potential and societal benefits across the globe [3]. Through 2026, it is anticipated that the world's energy demand would increase at an average annual rate of 3.4% due to better economic conditions that will speed up the use of power in both developed and developing nations. Renewable energy sources are predicted to overtake coal and other fossil fuels as the primary source of electricity generated worldwide by early 2025. It is projected that the proportion of renewable energy sources in the production of electricity will increase from 30% in 2023 to 37% in 2026, with the expansion of solar photovoltaic (PV) systems playing a significant role in this increase. Renewables are anticipated to reduce dependency on fossil fuels during this time by offsetting demand increases in developed economies such as the US and the EU. Regions with significant levels of variable renewable generation are establishing new markets and implementing certain operational measures to guarantee the stability of the power system. Increasingly, battery storage systems are being used to increase system flexibility and stabilize grid frequency, which is crucial for incorporating renewable energy sources [4]. Countries with significant wind energy potential are leveraging this resource to address electricity demand, particularly in regions with energy resource constraints. In areas where electricity access is below 50%, wind power, combined with solar energy, biomass, and hydro, offers a viable low-carbon solution [4].1.1 Cumulative Wind Power Capacity Worldwide Figure 1 gives a list of the largest onshore global wind farms that are currently operational, rated by generating capacity [5]. Figure 1: Cumulative wind power capacity worldwide [5] 1.2 Electric Wind Generator By converting mechanical energy into electrical energy, a wind turbine also referred to as an electric wind generator produces electricity. It neither generates energy nor generates more electrical energy than the rotor blades' mechanical energy. More mechanical power is needed to turn the rotor of a generator when the electrical demand, or "load," is higher. As seen in the wind electric farm depicted in Figure 2, wind power is used to produce mechanical power or electricity, providing energy to residences, workplaces, schools, and laboratories. Wind energy is initially transformed into mechanical energy by the wind turbine's generator, which subsequently turns that mechanical energy into electrical power [6].Figure 2: Wind electric farm [7] 2. REVIEW OF RELATED LITERATURE One of the most dependable renewable energy sources in the world is wind energy. Seasons, the time of day, and general weather patterns all affect average wind speeds, though. Periods of relatively weaker winds are often followed by multiple days of strong wind speeds at a particular place. Together, the United States, China, India, and Europe have 93% of the world's installed wind power capacity. Between 2000 and 2013, more than 100 GW of wind power capacity was built in Europe. Even though coal, natural gas, and oil account for more than 80% of the US's energy consumption, by the end of 2013, more than 61.1 GW of wind generating capacity had been constructed. China became the world leader in

wind energy, adding over 91 GW of capacity in just eight years to fulfil the demands of its tremendous industrialization, while India reached about 21 GW of cumulative wind power capacity by 2014 [4]. With average wind speeds ranging from 3.5 to 10 meters per second at elevations of 10 to 20 meters, Africa has a significant potential for wind energy. Significant progress is being made by the continent in the development of renewable energy [8]. For example, in Senegal and Kenya, wind energy accounts for 15% and 17% of total power output, respectively. The first Status of Wind in Africa report, released by the Global Wind Energy Council's Africa Wind Power program, gives a broad overview of the continent's wind business and forecasts substantial development. There are currently 83 wind farms operating in Africa, generating 9 GW of clean energy. With 140 projects scheduled to add an additional 86 GW of installed capacity, the project pipeline indicates that capacity might increase by more than 900% [8, 9]. Several major wind energy projects illustrate global developments in the area. The 522.8 MW Sagamore Wind Farm is an onshore wind project located in New Mexico, USA. Constructed in stages, the farm was put into operation in December 2020 after construction started in 2019 [10]. In response to a presidential mandate on renewable energy pilot projects released in December 2019 [11], ACWA Power developed the Azerbaijan 240 MW Wind Farm, a greenfield Independent Power Project (IPP). Similar to this, private IPPs are able to sell energy directly to consumers via the national grid thanks to Morocco's Khalladi 120 MW Wind Farm, which was built under the Renewable Energy Law. In 2014, ACWA Power purchased a majority interest in this project [11]. The Australian Renewable Energy Hub, originally known as the Asian Renewable Energy Hub, will be located in Australia's Pilbara region. This updated proposal, which was approved in January 2023, consists of seven projects with a combined wind and solar capacity of 26 GW with the goal of producing green hydrogen [12, 13]. Early vertical-axis windmills were employed for grain processing in the Seitan region of Iran and Afghanistan, which is where windmills first appeared. Horizontal-axis windmills, like the post or trestle mill, first appeared in Dutch Normandy around 1180 and swiftly expanded across Europe. With a mill house with a revolving tower cap and rotor blades, these ideas developed into the tower mill in the 14th century and, in the 16th century, the famous Dutch windmill, which is still in use today for conventional milling operations [14]. Wind turbines capture wind energy, which is the kinetic energy of flowing air, and transform it into mechanical energy and subsequently electrical energy. These gadgets, which are sometimes called wind generators, are crucial for supplying changing energy needs [15]. Understanding the energy, mechanical, structural, and construction aspects of wind turbine design, building, and operation is essential to creating efficient wind turbines. The sector's consistent advancement is demonstrated by Figure 3, which shows the expansion of wind energy capacity and production in the United States from 1999 to 2009 [16].The results obtained was taken by measuring voltage (V) output using Voltmeter and Current (A) output using Ammeter of the wind generator, the product of the two quantities gives Power (W) output from the wind electric generator per hour from 8am to 9pm each day for 7 days. From the results, the power output of the system varies between the time intervals due to non-steady nature of the wind velocity. The maximum power output of 8.82w was achieved, however, a steadier state of the power output is gotten in the evening hours between 6pm to 9pm most days than the morning, this shows that there is more wind pressure on the fan blades which gives more torque to the rotor shaft and which increases the revolution per minute (r.p.m) of the system, which gives a better output voltage and current from the generator. Graph 1 to 7 illustrate power (w) output of the wind electric generator against time (hour) from day 1 to day 7. The power of the system is measured by multiplying an intermittent measured voltage quantity (V) by a measured current quantity (A) at a stipulated time since the wind energy fluctuates. The result when compared with the theoretical value as calculated using design parameters from equation 1.0 proves the validity of the experiment. Power output of the system ranges from 3.0W to 8.82W, there is a significant fall in power between the hours of 3:00 Pm and 4:00 this is as a result of low wind velocity in all the days of measurement and a maximum accumulated power of 91.13W was achieved in a particular day of the series. 5. CONCLUSION The experimented values of the system correspond with the theoretical value as the power generated by the system from the tables does not exceed the theoretical value of 11.31W, however, the variation in the wind velocity is indicated in the graph with the rise and fall of the power flow curve plotted, a significant zero value power is seen due to condition that there is no availability of wind pressure at the stipulated time of the day, therefore, if the system parameters is expanded, larger value of power can be obtained, and when it is stored over a certain period of time, becomes a useful energy for the society.
