  • Circular economy: use of wind turbines blades as combustible and mix material for cement production

    One of the future challenges of wind energy is to find a solution to recycle old blades from decommissioned wind turbines. In this post I will try to summarize several possible alternatives and to describe in detail what I think is currently the best option: to use them as a component for the production of…

  • Lightning protection of wind turbine blades

    I have received a question from a reader regarding blades damaged by lightning. Specifically, the blade has been damaged before commissioning. At first sight the consequences could be less significant than usual, above all if the main crane is still on site and there is a set of spare blades available as happens frequently in…

  • Wind turbine blades damage – an introduction

    I have discussed in another post the different type of damages that a wind turbine blade can suffer and the various detection systems. There is an extensive list of potential problems: cracks, delamination, debonding, erosion of the leading edge (the first area of the blade to “see the wind”) are some of the issues observed. This variety…
