But you may be wondering how energy infrastructure, such as wind turbines that utilise the wind power, behaves in extreme weather like storms, heat waves, and lightning.

In this blog, we will learn how these turbines suffer and keep producing electricity, even in the toughest weather. So, let’s get started without any further ado!

Overview of Wind Turbine Components 

1. Foundation: The base of the turbines is fixed deep into the ground or seabed. It helps turbines to stay stable and prevents them from collapsing when strong winds or storms hit them.
   
2. Tower: The tower holds the turbine’s nacelle and rotor up when they are absorbing and suffering from wind forces. It is developed using solid materials like steel or concrete for strength and durability.
   
3. Nacelle: This housing includes important machinery like the generator, gearbox, and braking system. It is developed to reduce air conflicts and manage challenging weather conditions.
   
4. Blades: These blades are lightweight and developed using solid material like fiberglass-reinforced plastic. They handle wind loads and easily convert wind energy into rotating power.
   
5. Hub: It is located at the centre of the rotor. It connects the blades to the main shaft. It makes sure that stress from the blades is distributed evenly.
   
6. Yaw system: This system lets the nacelle and rotor rotate and face the wind. It improves the way energy is captured and maintains balance.
   
7. Control systems: Sensors and systems monitor wind speeds. They adjust the blades’ pitch to manage loads and maintain stability in extreme weather conditions.
