Induction hardening of wind energy plants and components

Constantly rising oil prices, global warming, alternative energies - buzzwords which we hear almost every day. Even when this excess of buzzwords already leads to saturation, the energy-hungry world cannot commit itself to seek new alternative and regenerative energy sources. In addition to solar and water energy, wind energy is probably the most significant current energy source. It is clean, inexpensive and constant. But how can this inexhaustible energy be "harvested"? The present article should illuminate some partial aspects of this question and thereby provide a glimpse of the technology of modern windmills. The goal here is to answer the question: What does wind energy have to do with induction hardening?
