Abstract

This study examines the main trends in the modern development of wind energy, addressing the critical tasks and proposing solutions for advancing wind energy technology. It includes theoretical calculations of the efficiency factor of wind turbines, particularly focusing on the Betz limit, which traditionally sets an upper bound on their efficiency. The research highlights the fallibility of Betz's limit calculations in both physics and mathematics, challenging its long-held assumptions. A novel formula for the true dependence of wind turbine efficiency on the utilized energy of the wind flow is derived, providing a more accurate representation of their performance. This new formula is supported by a graph illustrating the relationship between wind energy input and turbine efficiency. Additionally, the study explores various strategies and innovative approaches to enhance the efficiency of wind turbines, aiming to maximize their potential in harnessing wind energy. These findings contribute to the ongoing efforts to improve renewable energy technologies and increase the viability of wind power as a sustainable energy source.
