International Report Shows Historic Advancement of Global Investment in Clean Energy Technologies, with Decrease in Fossil Fuel Investments and Acceleration of Energy Transition by 2025.
The global energy landscape has reached a historic milestone. Global investment in technologies related to the energy transition reached US$ 2.3 trillion, the highest volume ever recorded, according to the annual report Energy Transition Investment Trends, released by BloombergNEF.
According to a report published by Agência Eixos and other outlets this Friday (30th), the survey confirms that, for the second consecutive year, investments in clean energy exceeded investments directed towards fossil fuels, widening the gap between the two energy models.
Global Investment in Clean Energy Reaches Historic Level by 2025
This data reinforces a structural shift in international capital flows. Even amidst geopolitical tensions, economic slowdown in some regions, and regulatory uncertainties, investors continue to prioritize solutions with lower environmental impact, greater efficiency, and alignment with global climate goals.

A study reveals the expansion of renewable energy procurement in Brazil and shows how companies are taking advantage of opportunities to reduce expenses, ensure energy efficiency, and strengthen strategic environmental commitments.
The advancement of global investment indicates that the energy transition has ceased to be merely a promise and has become a central consideration in economic decisions.
The report shows that global investment in clean energy grew 8% compared to 2024, consolidating a new annual record. The amount includes resources allocated to renewable sources, nuclear energy, carbon capture and storage, low-carbon hydrogen, electricity grids, and energy storage systems.
The substantial volume reflects the resilience of the sector. Despite high capital costs and volatility in financial markets, clean energy has maintained a growth trajectory, driven by public policies, corporate decarbonization commitments, and gradual reductions in technological costs.
This movement confirms that global investment in low-carbon solutions is becoming increasingly decoupled from short-term economic cycles, assuming a long-term strategic character.
Clean Energy Surpasses Fossil Fuels for the Second Consecutive Year
For the second consecutive time, investments in clean energy have surpassed allocations aimed at fossil fuels. In 2025, the difference reached US$ 102 billion, up from the US$ 85 billion recorded in 2024.
This result highlights a market inflection. For decades, fossil fuels concentrated the majority of global energy capital. However, growing regulatory pressure, the search for energy security, and the need to reduce emissions have been redirecting resources towards more sustainable alternatives.
Analysts believe that the advancement of clean energy over fossil fuels reinforces the consolidation of the energy transition as a central axis of global economic development.
Decline in Fossil Fuel Investments Marks a New Phase for the Sector
The BloombergNEF report indicates that investment in fossil fuel supply fell US$ 9 billion compared to 2024, marking the first annual decline since 2020.
The reduction was primarily driven by decreased spending on oil and gas exploration and production, as well as a decline in investments in fossil fuel power generation.
Investor caution is growing. Projects related to fossil fuels face higher regulatory risks, uncertainties regarding future demand, and pressure from institutional investors for environmental, social, and governance criteria.
Despite this, the report highlights that there was partial compensation through targeted investments in natural gas and coal, especially in countries still dealing with short-term energy security challenges.
Electrification Leads Global Investment in Energy Transition
Electrification was the main driver of global investment in the energy transition by 2025. Electrified transport accounted for the largest share of the analyzed volume, with US$ 893 billion directed towards electric vehicles and charging infrastructure, an increase of 21% compared to 2024.
The automotive sector is undergoing a profound transformation. Automakers have expanded their portfolios of electric vehicles, while governments have accelerated incentive policies and decarbonization targets for transportation.
The expansion of charging infrastructure has also consolidated itself as a key element to sustain the growth of clean energy. This progress reinforces the strategic role of electrification as a pillar for the global energy transition.
Renewables and Electricity Grids Remain at the Center of Global Investment
Following electrification, investments in renewable sources totaled US$ 690 billion in 2025, while investments in electricity grids reached US$ 419 billion. These numbers reflect the need for modernization of energy infrastructure to integrate intermittent sources and meet the growing demand for electricity.
Electricity grids have become essential for the transition. Without the expansion and digitalization of infrastructure, the growth of clean energy faces technical and operational limitations. Therefore, global investment in grids has gained prominence within national energy strategies.
Regulatory Uncertainties Affect the Pace of Investment in Clean Energy
Despite the high volume, the report points to a 9.5% decline in annual investment in renewable energy compared to 2024. The main factor was the introduction of regulatory uncertainties in the energy market in China, the largest in the world, affecting capital decisions in solar and wind projects.
The data reveals regulatory sensitivity. Changes in market rules can temporarily impact the flow of global investment, even in established sectors of clean energy. Still, experts assess that this is a cyclical adjustment and not a structural reversal of the energy transition.
Hydrogen and Nuclear Face Challenges in Attracting Capital
The low-carbon hydrogen and nuclear energy segments have maintained a trajectory of lower investment attraction. In 2025, investments in hydrogen totaled US$ 7.3 billion, while nuclear energy received US$ 36 billion.
The challenges are well known. High costs, long maturation timelines, and regulatory uncertainties continue to limit the progress of these sectors within the clean energy ecosystem, despite their strategic potential for the energy transition in the medium and long term.
What Does the Global Investment Record Reveal About the Future of Energy?
The new record of US$ 2.3 trillion confirms that global investment in clean energy has entered a phase of consolidation. Even with a slowdown in the growth rate—from 27% in 2021 to 8% in 2025—volumes remain high and comfortably exceed investments in fossil fuels.
Capital is reshaping the energy system. The growing preference for low-carbon solutions indicates that the energy transition is no longer just an environmental agenda but a central economic strategy, with direct impacts on competitiveness, innovation, and energy security.
The movement observed in 2025 signals that the future of energy will be increasingly clean, electrified, and integrated, consolidating a historical shift in how the world produces, distributes, and consumes energy.
