Clean Technology (CleanTech) Global Market Report 2025

The clean technology (cleantech) market size has grown rapidly in recent years. It will grow from $759.05 billion in 2024 to $837.53 billion in 2025 at a compound annual growth rate (CAGR) of 10.3%. The growth in the historic period can be attributed to increasing demand for electric vehicles, rising environmental awareness among consumers and businesses, rising demand for sustainable construction, increasing integration of renewable energy sources, and increasing government support and incentives.

The clean technology (cleantech) market size is expected to see rapid growth in the next few years. It will grow to $1.25 trillion in 2029 at a compound annual growth rate (CAGR) of 10.6%. The growth in the forecast period can be attributed to the rise of hydrogen as a clean energy, rising adoption of second-life EV batteries, growing demand for zero-emission transportation, growing energy security concerns, increasing industrial energy efficiency mandates, and growing green hydrogen infrastructure. Major trends in the forecast period include advancements in battery technologies, advancements in clean energy technologies, developing circular economy models, innovation in floating wind farms, and integration of artificial intelligence in energy efficiency platforms.

The forecast of 10.6% growth over the next five years reflects a modest reduction of 0.3% from the previous estimate for this market. This reduction is primarily due to the impact of tariffs between the US and other countries. Broad-based tariffs on imported rare earth metals, power electronics, and clean tech sensors are expected to inflate costs for U.S. cleantech developers and integrators. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The increasing integration of renewable energy sources is expected to drive the growth of the clean technology (CleanTech) market in the coming years. Renewable energy sources, such as solar, wind, and hydropower, are naturally replenishing and provide sustainable alternatives to fossil fuels. The rise in renewable energy adoption is largely due to growing concerns over climate change and the need to reduce emissions, which has led to a shift away from fossil fuels toward cleaner alternatives. CleanTech facilitates the seamless integration of these renewable energy sources by offering advanced technologies and smart infrastructure that optimize energy generation, storage, and distribution across the grid. For example, in March 2024, the European Environment Agency, a Denmark-based organization, reported that in 2022, 23% of the energy consumed in the European Union (EU) came from renewable sources, up from 21.9% in 2021. This growing integration of renewable energy sources is a key factor driving the clean technology market.

Leading companies in the clean technology (CleanTech) market are focusing on adopting innovation-support initiatives such as accelerator programs to nurture startups, drive sustainable solutions, and accelerate the adoption of green technologies. Accelerator programs are fixed-term, cohort-based initiatives that offer startups mentorship, resources, and funding to help them scale rapidly. For instance, in January 2025, FedTech, a U.S.-based venture firm, launched the Four Corners Cleantech Accelerator. This program aims to foster clean energy innovation across Arizona, Colorado, New Mexico, and Utah. It provides a structured series of workshops covering business modeling and cleantech commercialization, as well as tailored advisory services for established businesses, including support on IP, market strategies, and pitching. The program emphasizes inclusivity, focusing on underserved entrepreneurs and promoting collaboration with national laboratories and industry experts.

In December 2024, Alternus Clean Energy Inc., a U.S.-based renewable energy company, acquired LiiON for an undisclosed amount. This acquisition is part of Alternus Clean Energy's strategy to enhance its energy storage capabilities, expand its market reach, and accelerate long-term growth by providing more comprehensive and sustainable energy solutions. LiiON, LLC is a U.S.-based technology company specializing in renewable and stored energy solutions.

Clean technology (CleanTech) encompasses a wide range of products, services, and processes that utilize renewable materials and energy sources, reduce emissions and waste, and minimize environmental impact. The main objective of CleanTech is to enhance sustainability and efficiency while addressing global environmental challenges such as climate change, pollution, and resource depletion.

The primary types of CleanTech include renewable energy technologies, energy storage solutions, energy efficiency solutions, water and waste management, agriculture and food systems, and air and environmental management. Renewable energy technologies involve methods and systems that generate energy from naturally replenishable sources such as sunlight, wind, water, biomass, and geothermal heat. These technologies include solar photovoltaics, battery and energy storage systems, onshore and offshore wind turbines, hydrogen and renewable gases, and carbon capture and storage, among other innovations. CleanTech is applicable across various industries, including transportation, manufacturing, utilities, chemicals, electronics, and agriculture. It serves a broad range of end users, including governments, corporations, non-governmental organizations (NGOs), and individual consumers.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The sharp rise in U.S. tariffs and the ensuing trade tensions in spring 2025 are having a notable impact on the utilities sector, particularly across power generation, grid modernization, and renewable energy initiatives. Increased duties on imported equipment such as turbines, transformers, solar panels, and battery storage systems are driving up both capital and operational expenses for utility companies, prompting many to delay projects or pass higher costs on to consumers through increased energy rates. The water and waste management sectors are similarly affected, as tariffs inflate the cost of essential machinery, piping, and treatment technologies. Moreover, retaliatory tariffs from key trading partners have disrupted the supply of critical raw materials - such as rare earth elements vital for clean energy technologies - posing further challenges to the shift toward sustainable energy. In response, the sector is increasingly focusing on domestic procurement, digital transformation, and efficiency-enhancing innovations to control rising costs while safeguarding energy reliability and meeting regulatory demands.
