Wind Turbine Composites Material Market Report Scope:

By Fiber Type

Glass fiber segment accounted for 68% of the market value share in 2024 on account of its low cost, superior mechanical strength, and established usage in wind blade production. It's a global leader, particularly for onshore installations, in big, utility-scale wind projects around the world. At the same time, the use of carbon fibre proves increasingly attractive for offshore applications due to its light weight, high stiffness, in combination with fatigue resistance, which is particularly important for any long-span blade operating in a turbulent wind environment.

By Resin Type

Epoxy segment was the leading segment with a market share of 52% in 2024. Wind turbine composite production prefers epoxy resins due to their excellent mechanical properties, adhesion and thermal properties. These are the ones most commonly combined with glass and carbon fibers in the production of blade. Other resin systems (for example, polyester, vinyl ester) are also employed, especially in cost sensitive cases, and smaller wind turbines.

By Application

Blade held a market share of 75% in 2024 leading the global blade market. The blades of wind turbine are the largest and most important components of the structure of a wind turbine, in which composite materials are used. Add More Length, More Power Doubling the blade length to increase the capacity of the turbine to generate electricity would require cutting-edge composite materials to maintain strength and durability while reducing weight. Nacelles and hubs are also very significant parts when it comes to increasing turbine sizes, which requires materials with high mechanical properties as well as environmental resistance.

Regional Analysis

Asia-Pacific was the leading region in the global wind turbine composites with the highest value share of 38% in 2024. Much of this is due to swift wind energy expansion in China and India, solid government backing for renewables, particularly clean energy and huge commitments to both onshore and offshore wind projects. China, in particular, is the global leader in wind power capacity and wind turbine manufacturing, and this is a contributor to the demand for composites. Europe made a close second, as countries such as Germany, the UK, and Denmark invested heavily in offshore wind farms.

U.S. Secretary of the Interior Doug Burgum announced four policy measures to advance President Donald J. Trump’s commonsense approach to affordable, reliable energy development in America. In alignment with President Donald J. Trump’s directives, the Department of the Interior is ending special treatment for unreliable energy sources, such as wind. This includes evaluating whether to stop onshore wind development on some federal lands and halting future offshore wind lease sales. The Department will also study how constructing and operating wind turbines might affect migratory bird populations.

These changes are part of a broader America First energy strategy focused on affordability, reliability, and accountability for the American people.  As part of efforts to support a stable power grid and elevate local voices, the Department will improve consultation with tribes, local communities, and the fishing industry regarding offshore wind projects. The latest reforms aim to ensure that energy development reflects local land-use priorities and community values.

“These policy changes represent a commonsense approach to energy that puts Americans’ interests first,” said Secretary Doug Burgum. “Leveling the playing field in permitting supports energy development that’s reliable, affordable, and built to last. We’re also making sure tribes and local communities have a real seat at the table. This move is about responsible energy growth that works for every American.” 

Announcements include: 

Stopping Preferential Treatment for Wind Projects 

Secretary’s Order No. 3437, “Ending Preferential Treatment for Unreliable, Foreign-Controlled Energy Sources in Department Decision-Making,” directs the Department of the Interior to end preferential treatment for unreliable energy sources like wind. The Order calls for identifying policies biased in favor of wind and solar energy and halting support for energy supply chains controlled by foreign rivals. In line with the January 20, 2025, Presidential Memorandum on Wind Energy, the Department will review its policies to identify and remove favoritism toward unreliable energy, with a report of recommended reforms to be submitted under Section 5 of Executive Order 14315.  

Restoring Congress’s Mandate to Consider All Uses of Our Public Lands and Waters Equally

The Department will consider withdrawing areas onshore with high potential for wind energy development to ensure compliance with legal requirements for multiple use and sustained yield of public lands. This means balancing energy development with other important uses—such as recreation and grazing—and protecting BLM-managed lands, as envisioned by Congress. Additionally, at the end of the last administration, over 3.5 million acres offshore were designated as Wind Energy Areas, which are pre-approved zones where the federal government could auction leases for offshore wind development. By terminating these Wind Energy Areas, we are safeguarding our coastal environments and local economies from unchecked development, while ensuring our power grids are not underpinned by unreliable, subsidized energy sources.  

Enhancing Stakeholder Engagement for Offshore Wind Development 

The Department will strengthen its guidance to ensure more meaningful consultation regarding offshore wind development, especially with tribes, the fishing industry, and coastal towns. The construction and operation of offshore wind turbines have disproportionate impacts on these stakeholders, from disrupting commercial fishing to driving away tourism. By addressing current gaps, this updated guidance will support greater collaboration, transparency, and respect for community and regional priorities.   

Reviewing the Consequences of Developing Wind Turbines on Migratory Birds 

The Department will conduct a careful review of avian mortality rates associated with the development of wind energy projects located in migratory flight paths and determine whether such impacts qualify as “incidental" takings of birds under the Migratory Bird Treaty Act and related laws. The Department will also conduct a review of the applicable regulations to determine the appropriate approach to permitting these activities, identifying violations of the applicable statutes, and related penalties.

ComEd and the Metropolitan Mayors Caucus recognized a diverse group of communities completing a program designed to help prepare them to accommodate the growth of electric vehicles (EVs) and EV infrastructure. Through their completion of the EV Readiness Program, 17 local governments have demonstrated actions required to create permitting, safety plans and local policies that help make EVs more accessible in communities throughout northern Illinois.

“The EV Readiness Program provides cities and counties across the state with the foundation they need to support EV growth within their communities,” said ComEd President and CEO Gil Quiniones. "The shift to EVs will lower emissions and enhance air quality, key milestones on the journey to building a more sustainable future in Illinois.”

The EV Readiness Program was launched by ComEd and the Caucus in 2022 to help prepare municipalities to accommodate the growing number of EVs in Illinois, which includes more than 145,000 currently registered in Illinois today, and the vast majority of them in ComEd’s northern Illinois service territory. EV adoption is expected to increase in the future, as the state of Illinois, through its Climate and Equitable Jobs Act (CEJA), has set a goal of getting to 1 million EVs on the road by 2030.

“With each graduating cohort, the EV Readiness Program continues to grow stronger and more impactful,” said Kevin Burns, Mayor, City of Geneva, Illinois, and Metropolitan Mayors Caucus Environment and Energy Committee Chair and Immediate Past Executive Board Chair. “This third cohort reflects the steady momentum our region is building toward a cleaner, more connected transportation future.”

A diverse mix of 17 communities becomes the third cohort to graduate from this program during a ceremony held at the Illinois Institute of Technology (Illinois Tech) in Chicago, Illinois. To date, the program has reached 38 communities in its three unique cohorts.

The participating local governments in this third cohort range from large urban cities to suburban communities, with representation from north, central, south and west sides of the region. The third cohort communities are:

• Broadview
• Brookfield
• Chicago
• Countryside
• DeKalb
• DuPage County
• Glenview
• Highland Park
• Johnsburg
• Lindenhurst
• Park Forest
• River Forest
• Rockford
• Rolling Meadows
• Streamwood
• Vernon Hills
• Warrenville

“By learning from each round and improving the program along the way, the Caucus is helping communities like ours turn ambition into action—and laying the groundwork for a robust, equitable EV ecosystem across northern Illinois,” said Nancy R. Rotering, Mayor, City of Highland Park, Illinois, and Caucus Executive Board Chair.

The EV Readiness Program is guided by a comprehensive EV Readiness Checklist of 132 possible municipal actions to demonstrate preparedness for EV integration.

“The City of Chicago is proud to have earned Gold in the Metropolitan Mayors Caucus’ EV Readiness Program. This recognition is a testament to our deep commitment to accelerating the transition to clean transportation in every neighborhood,” said City of Chicago Mayor Brandon Johnson. “Through this program, we’ve strengthened collaboration across City departments and are building the infrastructure and policies needed to expand access to EVs, reduce emissions and deliver cleaner air and healthier communities for all Chicagoans.”

“As we electrify transportation across the country, we must strive to build smarter, faster and more accessible charging infrastructure here in Illinois,” said U.S. Senator Dick Durbin. “By assisting 17 of our communities in Chicagoland to complete the EV Readiness Program, The Metropolitan Mayors Caucus is accelerating the transition to clean transportation and strengthening Illinois’ commitment to combatting the climate crisis. I’ll continue working with Senator Duckworth and our local leaders to maintain Illinois’ position as a leader in electric vehicles and charging infrastructure.”

During the third cohort, three communities earned Gold status, which reflects the most advanced participation under the program. The City of Chicago “leveled up” to Gold status from the Bronze designation it received in the second cohort. The Village of River Forest and the City of Rolling Meadows also achieved Gold status in this cohort.

DuPage County “leveled up” from Bronze to Silver status by pursuing additional EV readiness actions, including participating in ComEd’s Fleet Electrification Assessment. This comprehensive assessment helps communities and other commercial customers plan the transition to an all-electric fleet, providing the customer the opportunity to assess proper vehicles for their fleet, to plan and determine charging infrastructure needs, to measure total cost of electrification and emissions reduction, and to find information about ComEd and other incentive programs they may qualify for. With ComEd’s assistance, numerous EV Readiness communities have participated in the free assessment, including the Cities of Chicago, Highland Park and Rolling Meadows, as well as the Villages of Park Forest and River Forest.

“The results of the EV Readiness program show what’s possible when cities decide to lead instead of follow,” said Rolling Meadows Mayor Lara Sanoica. “Rolling Meadows is proud to be recognized among the leaders creating a more sustainable future for our region.”

“The City of Rockford is honored to participate in the EV Readiness Program, which has played a vital role as we work to modernize our transportation system and ensure the benefits of clean mobility reach every neighborhood,” said Tom McNamara, Mayor, City of Rockford, Illinois. “This program helped us lay the groundwork for a more sustainable, inclusive future – one that supports economic opportunity, environmental stewardship, and community well-being. We look forward to building on this momentum.”

Participation in the EV Readiness program has proven to help communities increase EV registrations, while also helping them develop and qualify for additional funding opportunities. Communities like Chicago and Rolling Meadows have qualified for EV grant funding to create better EV access for their cities. By conducting an initial fleet EV suitability analysis, the City of Chicago successfully secured over $11 million in federal grants to replace older diesel vehicles with new electrified vehicles.

In response to the rise of EVs in the region, the EV Readiness program was developed by a coalition of over 70 regional partners including local mayors, managers, and other local government staff members, as well as representatives from councils of governments, regional planning organizations, EV charging station companies, IBEW (International Brotherhood of Electrical Workers), Argonne National Laboratory and ComEd.

The EV Readiness Program is one example of significant investments that ComEd is making to support customers and communities in the transition to EVs. Earlier this year, ComEd launched over $100 million in EV rebate funding to support residential, business and public sector customers with expanding EV use, by funding fleet EVs and EV charging infrastructure projects. To ensure equitable access to EVs, ComEd’s programs reserve over 50 percent of all funding for equity investment eligible communities (EIEC), as defined by the state of Illinois, or for low-income customers.

A new analysis by The Brattle Group found that Sunrun’s (Nasdaq: RUN) fleet of home batteries across California was the largest contributor to a historic distributed power plant dispatch event that delivered an average of 535 megawatts to the grid—enough to power more than half of the city of San Francisco.

Multiple distributed power plant aggregators, of which Sunrun is the largest, discharged home batteries in coordination with the California Energy Commission, the California Independent System Operator, and local utilities during a scheduled test event between 7 and 9 p.m. on Tuesday, July 29. The goal of the event was to prepare for anticipated need-based dispatches during heat waves in August and September.

The Brattle Group found that the output from more than 100,000 residential batteries resulted in “a visible reduction in net load” across the statewide grid when output typically is most valuable to the system.

“Performance was consistent across the event, without major fluctuations or any attrition,” said Ryan Hledik, Principal at The Brattle Group. “Events like these demonstrate to system operators that residential batteries provide dependable, planning-grade performance at scale.”

“Residential batteries—and other sources of distributed flexibility—can serve CAISO’s net peak, reduce the need to invest in new generation capacity, and relieve strain on the system associated with the evening load ramp,” Hledik said.

Sunrun’s home batteries supplied more than two-thirds of the total energy dispatched during the event—averaging more than 360 megawatts over the two hours—and have the capability to deliver this critical energy every day. Sunrun’s batteries acted in the same way as a traditional power plant and decisively knocked down the state’s evening peak demand for electricity.

“This customer-led solution is a win-win for households and the grid,” said Sunrun CEO Mary Powell. “Distributed home batteries are a powerful and flexible resource that reliably delivers power to the grid at a moment's notice, benefiting all households by preventing blackouts, alleviating peak demand, and reducing extreme price spikes."

This is the second time this summer that Sunrun’s fleet of home batteries helped reduce California’s peak energy demand. On June 24, Sunrun’s statewide distributed power plant dispatched 325 megawatts of peak power from 7 to 9 p.m. Participating Sunrun customers are compensated up to $150 per battery per dispatching season, and Sunrun is paid for dispatching the batteries.
