How Do Wind Turbines Work

4/10/2023

Key Points

  • Wind turbine operation and purpose: Wind turbines convert wind into electricity by propelling turbine blades to rotate, which then powers a generator to produce electricity. These turbines are used on wind farms, either on land or offshore, to supply power to electrical grids for homes, businesses and sometimes an entire region. 
  • Types of wind turbines: There are land-based turbines used for generating commercial electricity, offshore turbines that are more powerful due to higher wind speeds over water and distributed wind turbines for smaller-scale electricity generation near the end user, often in remote areas.
  • Wind turbine technicians: Technicians perform wind turbine inspections, troubleshoot issues and are responsible for repairs and maintenance. These roles require precise technical skills, problem-solving abilities and strong communication skills.
  • Wind turbine technician training: Aspiring technicians can enroll in programs such as the 30-week Wind Turbine Technician training program offered by Universal Technical Institute (UTI), where they can develop the skills to maintain and repair wind turbine components.
  • Working and industry conditions: Wind turbine technicians typically work outdoors and may be required to work in challenging conditions, including at great heights and in remote locations. Wind turbine service technician is one of the fastest-growing occupations in the U.S.

Ever driven past a wind farm and wondered, “How do wind turbines work and what do they do?”

The simple answer is – they help power electrical grids via renewable energy. If you’re intrigued by these towering turbines, keep reading.

In this guide, we’ll dive deeper into what a wind turbine is, how it works, different types of wind turbines and how you can train for a career working on them! 

What Is a Wind Turbine?

FY22-MIAT-ENERGY-WIND-Stock-0003.png

A wind turbine converts wind into electricity. The wind propels the turbine blades to rotate, and this rotation then spins the turbine's generator, which generates electricity.

What does a wind turbine do?

When the wind blows, it turns the turbine's propeller-like blades around a rotor, which is connected to a main shaft. This shaft then spins a generator to create electricity. The electricity produced by each turbine in the farm is collected into the electrical grid and distributed for use in buildings that need power.

What are the main components of a wind turbine?

FINAL_Infographic-Wind-Turbine_1035909.jpg

The working of a wind turbine relies on four main components:

  • Rotor: Responsible for using aerodynamic lift to capture wind energy and converting it into rotational energy to spin the shaft.
  • Blades: Designed for minimal air resistance to efficiently capture wind energy through aerodynamic lift.
  • Nacelle: An enclosure for the turbine's main components, located at the top of the wind turbine. Contains its main components such as the gearbox, generator and brake system.
  • Tower: Helps support the weight of all components and provides stability in windy conditions.

What Is Wind Energy Used For?

Wind turbines are typically found on wind farms, where many wind turbines feed electric power into an electric power grid. Energy from wind can then be used to fuel homes, large buildings and even entire zip codes.

Wind farms are strategically placed in areas with ideal wind speeds and consistency, such as open plains, hilltops or offshore in open water, depending on the energy needs. Learn more about the different types below.

Land-based wind

Land-based wind turbines are typically used to generate large amounts of commercial electricity. These turbines are installed on structures built over open land, such as farmer's fields or hillsides, and take a lot of space to set up. Wind-generated electricity then travels through the electrical grid to power nearby homes and businesses.

Offshore wind

Offshore wind turbines operate in the same way as onshore wind turbines but are located in bodies of water such as oceans. They have larger rotors than their land-based counterparts to fully use the relatively higher speed of the wind over water, making them more powerful electricity producers. Because of their remote location and high operational capacity, offshore wind farms are also more expensive to build and require specialized installation equipment.

Distributed wind

Distributed wind turbines generate electricity on a smaller scale and are frequently located near the end user's home or business, eliminating or reducing the need for transmission lines and their associated costs. These turbines are especially useful in remote areas with otherwise limited or nonexistent access to electricity.

Types of Wind Turbines

Wind turbines come in various shapes and sizes, each tailored for specific environments and energy needs. This diversity allows for wind energy to be harnessed in a range of locations—from vast plains to offshore expanses. Let’s explore the different types of wind turbines, as well as their unique features and applications:

  • Horizontal-Axis Wind Turbines (HAWTs): The most common type. Ideal for large-scale wind farms. HAWTs have tall towers and blades that rotate around a horizontal axis.
  • Vertical-Axis Wind Turbines (VAWTs): Less common but used for their specialized ability to catch wind from any direction without needing to pivot. Feature a vertical rotor.
  • Offshore Wind Turbines: Specifically designed for installation in bodies of water. Offshore turbines harness the consistent, high-speed winds found offshore.
  • Ducted Wind Turbines: Suitable for areas with low wind speeds. These turbines use a funnel to channel and accelerate wind onto the blades, potentially increasing efficiency.
  • Micro Wind Turbines: Small-scale turbines designed for individual or small-scale use, such as residential homes or small businesses. Often used to supplement traditional power sources.

Wind Energy Technicians

Wind turbine technicians are responsible for the efficient and safe operation of wind turbines. They often perform inspections, troubleshoot technical issues, perform repairs and maintenance, monitor performance metrics and install new equipment or upgrade existing systems.

These technicians must also effectively communicate the technicalities of any relevant project updates to customers and teammates. This way, everyone involved in the success of these projects knows exactly what is required and whether any issues will impact their progress.

Technician traits

Wind turbine technicians must use math and science reasoning skills to decipher technical diagrams. They must be able to effectively solve problems, which can help them diagnose and repair system errors.

Because they work with intricate machinery, wind technicians must also be well-versed in their industry's technology and have up-to-date computer skills. Effective communication is also essential, whether they’re providing detailed technical instructions to teammates or speaking to customers regarding the service being performed.

Technicians operating on wind turbines must use tools and hoist heavy pieces of equipment onto turbines. Doing so is much easier with manual dexterity and physical strength. Last but certainly not least, technicians must have enough technical knowledge and aptitude to perform their responsibilities correctly.

Technical training

Technical training and a solid understanding of safety protocols can help wind turbine techs complete their tasks successfully. Technical training consists of wind turbine technician courses that teach the skills needed to diagnose malfunctions in wind turbine systems, troubleshoot issues and understand electrical diagrams.

Working conditions

Wind turbine technicians typically work outdoors, increasing their exposure to severe weather whenever it occurs. They often have to maneuver up tall towers or through tight spaces inside large turbines and could be expected to repair blades or machinery while hundreds of feet above the ground.

Employers may require wind turbine technicians to permanently relocate to the worksite, which could be situated in remote and isolated areas. They must also work with potentially hazardous materials, so a fundamental understanding of safety protocols is critical. Certain employers may also require wind technician safety credentials from their employees to ensure that the worksite complies with local safety regulations.

Fortunately, they frequently work in groups. So, if you get an entry-level wind turbine technician job, you could be surrounded by teammates who have your back. To make the most of this camaraderie, communication and teamwork skills are required!
