The onshore segment, valued at USD 71.80 billion in 2019, remains a key area of market expansion. Onshore wind energy projects are experiencing steady growth, particularly in countries with vast land resources like the United States, China, and India. However, offshore wind farms, with their larger turbines and higher capacity, are emerging as the focal point of future growth. Offshore developments are particularly advantageous in regions with high wind speeds and limited land availability.
Wind turbine systems rely on several critical components to function efficiently. Here’s a closer look at the key product segments:
Wind Turbine Rotor Blades: These are the most vital component, as they capture the wind’s kinetic energy and convert it into mechanical energy.
Wind Turbine Gearboxes: Gearboxes are essential for transferring mechanical power from the blades to the generator, which converts it to electrical energy.
Wind Turbine Generators: These convert mechanical energy into electrical energy that can be fed into the grid.
Wind Turbine Towers: Towers support the turbine and ensure it is positioned at an optimal height to capture wind energy.
Data Callout:
Rotor blades represent the largest share of the market, followed by gearboxes and generators.
The Asia-Pacific (APAC) region is projected to contribute significantly—around 39%—to the global wind turbine components market growth during the forecast period. In 2023, the region accounted for over 40% of the market share, with China leading the charge in wind energy development.
China: Largest producer and consumer of wind turbine components, with significant government backing.
Europe: Steadfastly focused on meeting climate goals, particularly in offshore wind projects.
North America: Increasing investments in offshore wind, supported by growing energy demands and policy incentives.
Mini Case Study: Vestas' Expansion Strategy Vestas Wind Systems, a key player in the wind turbine sector, recently made significant strides by acquiring GearDrive Solutions, a leading gearbox manufacturer.
