Abstract - In the face of a rapidly growing global

reliant source of intermittent renewable energy to offset rising fossil fuel prices.

population, our energy demands are skyrocketing exponentially. Projections indicate that within the next nine years, the energy requirements will double, posing a significant challenge. Compounding this issue is the looming threat of global warming, an existential crisis exacerbated by the escalating carbon emissions resulting from human activities. As our planet steadily warms with each passing decade, it becomes imperative to address the root cause of this environmental peril – carbon emissions. Notably, traditional energy generation methods, particularly from nuclear power plants and fossil fuel-driven vehicles, contribute significantly to this predicament. With fossil fuel reserves depleting, an urgent exploration of sustainable alternatives for long-term energy generation is paramount. Wind energy – a renewable and zero-carbon source that holds immense promise. While wind mills have graced our landscapes for over a century, the exploration of vertical axial wind turbines (VAWT), specifically the Savonius type, remains relatively uncharted territory. This report delves into the viability of Savonius-type VAWTs and introduces a groundbreaking concept of twisted blades and aimed at enhancing turbine efficiency through experimental approaches.

1.1 Vertical Axis Wind Turbine Vertical-axis wind turbines have the main rotor shaft arranged vertically This configuration has the benefit of not requiring the turbine to face the wind in order for it to function, which is useful in locations where wind direction is very variable, like when the turbine is integrated into a building. In order to improve accessibility for maintenance, the generator and gearbox can also be positioned close to the ground by using a direct drive from the rotor assembly to the ground-based gearbox. The advantages of VAWTs versus horizontal-axis wind turbines are numerous. They can be located closer to the ground, where the wind speed is lower, so they don't need as much wind to generate power. They can be installed in a variety of settings and require less maintenance because they are closer to the ground.

1.2 Types of Vertical Axis Wind Turbine Savonius Wind Turbine Vertical Axis Wind Turbine (VAWT) of drag type is the Savonius wind turbine. The typical design consists of a revolving shaft that catches the incoming wind with two or three scoops. It is utilized when dependability is more crucial than efficiency because of its straightforward and sturdy form and rather poor efficiency. Approximately only half of a Savonius wind turbine creates positive torque; the other half moves against the wind and produces negative torque, which contributes to the turbine's low efficiency.

1.INTRODUCTION With the advancement of technology, the rate of energy consumption is rising daily. The amount of energy consumed worldwide has grown by almost a third since 2000 and is expected to do so for some time to come. In 2018, the worldwide energy demand climbed by 2.9%. If nothing changes, by 2040, the global energy consumption is expected to reach 740 million tera joules, or an extra 30% growth. It is becoming increasingly difficult to generate energy with nonrenewable resources at this rate. In many nations, wind turbines are employed as a more cost-effective and less-

Darrieus Wind Turbine A vertical axis wind turbine (VAWT) of the lift type is the Darrieus wind turbine. A set of curved airfoil blades with their tips fixed to a revolving shaft were part of the original concept. On the other hand, other designs—known as Hrotor or Giro mill Derrius wind turbines—use vertical
