Growing concern for the environment and the need to rationalize the consumption of natural resources are prompting scientists in a variety of fields to adopt ecological approaches that promote the use of resources. The energy sector is particularly affected, requiring action plans to reduce not only the environmental footprint of energy production methods, but also that of the manufacturing processes of production infrastructures. In this context, the growing global demand for renewable energy has increased the use of wind turbines, whose blades are generally made from conventional composites such as fiberglass. These materials have limitations in terms of durability and environmental impact. This paper analyses the dynamic performance of a vertical axis wind turbine equipped with innovative bio-composite blades, using the finite element method. The simulations revealed a significant improvement in the energy performance of blades made from this bio-sourced material. In addition, the use of these innovative bio-composites reduced the overall carbon footprint of wind turbine blades, offering a more environmentally-friendly solution. The results of this study highlight the potential of bio-composites in the wind energy sector, paving the way for more sustainable technologies.
