Bruised, Not Yet Broken: The State of U.S. Clean Energy

Read the headlines out of Washington and it's easy to assume America's clean energy push is running out of steam. The reality on the ground is a bit more encouraging: private capital keeps flowing into low-carbon technologies, advanced biofuels are scaling rapidly, and solar and wind continue their steady climb. Federal enthusiasm has cooled, but the underlying transition is still moving, and the rest of the world is still counting on it.

In 2025, the United States continued to play a significant role in advancing renewable energy, driven primarily by the economic competitiveness of solar and wind power, as well as private investment and state policies. Despite a federal political context more favorable to fossil fuels and debates over environmental regulations, the country maintained consistent growth in the clean energy sector. Simultaneously, the US preserved its strong position in the biofuels market, especially in the production of renewable ethanol and diesel, supported by established regulatory targets and mechanisms.

Notable expansion of biofuels

The United States occupies a prominent position in the increase of biofuel production, with an annual ethanol production exceeding 55 billion gallons, corresponding to approximately 40% of the world's production of this fuel. According to the U.S. Energy Information Administration (EIA, 2024), this volume establishes the country as one of the main global players in the sector. This performance is supported by structuring policies, such as the Renewable Fuel Standard (RFS), which was implemented by the United States Environmental Protection Agency (EPA), requiring the inclusion of renewable fuels in the energy mix of the transportation sector. According to the International Energy Agency's (IEA) Renewables Report 2024, the maintenance of these actions has ensured high levels of blending in 2025, consolidating the U.S.'s position as one of the three main global producers of biofuels, along with Brazil and the European Union.

In recent years, growth has been particularly driven by the expansion of renewable diesel, whose production capacity grew by more than 300% between 2020 and 2024, with a strong concentration in states such as California and Texas as reported by the U.S. Energy Information Administration (EIA, 2025). At the same time, investments in advanced biofuels have reduced dependence on food inputs and improved the environmental efficiency of the sector. According to the International Energy Agency (IEA), this progress consolidates the United States as one of the world's leading centers for innovation and production of biofuels, contributing significantly to the energy transition and the reduction of emissions in the transportation sector. According to the International Energy Agency (IEA, 2024), this progress strengthens the United States' position as one of the leading global centers for innovation and production of biofuels, contributing significantly to the energy transition and reducing emissions in the transportation sector.

Governmental Actions and Transformative Initiatives

The United States government has promoted the biofuel sector through policies and incentives that complement the Renewable Fuel Standard (RFS), with emphasis on the Inflation Reduction Act (IRA), which established strategic tax credits for low-carbon fuels, including Sustainable Aviation Fuel (SAF). Furthermore, initiatives such as the Clean Fuel Production Credit (Section 45Z), whose importance intensifies from 2025 onwards, have strengthened support for the production of renewable fuels with lower carbon intensity. Simultaneously, state actions, such as California's Low Carbon Fuel Standard (LCFS), continue to play a crucial role in generating intense market demand for biodiesel, renewable diesel, and SAF. These measures have been essential to stimulate new investments and consolidate the expansion of emerging markets, especially in the aviation sector, where the demand for sustainable energy solutions is growing rapidly.

The Impact of the International Energy Agency (IEA)

In its “Renewables 2024 report”, the International Energy Agency (IEA) highlighted that installed renewable energy capacity continues to increase rapidly in the United States and globally. According to the IEA, renewable energy growth in the US is among the most significant among developed economies, with large increases primarily in the solar and wind sectors. This demonstrates a continued commitment to the energy transition, despite recent regulatory challenges. Worldwide, renewable capacity is expected to increase approximately 2.7 times by 2030, driven by clean energy policies in over 130 countries, reduced technological costs, and growth in public and private demand. However, this progress is still below the target of tripling global capacity by 2030, established at COP28. According to the same report, by the end of the decade, new renewable energy installations are expected to exceed 5,500 GW, with solar and wind power accounting for approximately 95% of this increase. This underscores the fundamental importance of renewable energies in reducing carbon emissions and changing the global energy mix.

Limitations and Perspectives:

Although there has been progress, the IEA warns that global investment in renewable energy is still insufficient, especially in developing economies. Furthermore, it highlights the need for greater international collaboration to achieve long-term climate goals. In the United States, despite the country experiencing an unprecedented volume of investment in clean energy after the passage of the Inflation Reduction Act (IRA), which between 2022 and 2025 incentivized more than $422 billion in investment and generated more than 400,000 jobs in the clean energy sector (Inflation Reduction Act, 2025), energy policy has raised doubts for this sector following the re-election of Donald Trump in 2025. The government has suggested reducing or canceling tax incentives for solar and wind energy in the federal budget, in addition to prioritizing investments in fossil fuels. This has resulted in a decrease in some initiatives and greater instability in renewable energy investment flows (Reuters). Conversely, remaining tax incentives and private investments continue to attract capital to low-carbon technologies, especially in areas such as advanced biofuels and clean energy infrastructure. This indicates a chance to fully leverage the renewable potential of the US, even in the face of political and financing obstacles.

Economic and Environmental Assessment

The United States progress in the renewable energy sector has had significant effects on both the environment and the economy. The growth of renewable sources, such as solar, wind, and biofuels, has helped to progressively reduce greenhouse gas emissions and decrease dependence on fossil fuels in strategic sectors. At the same time, the growth of clean energy has stimulated private investment, strengthened industrial chains, and expanded job creation in the energy sector, contributing to the development of a more resilient and low-carbon economy.

Renewable Energy Sources as a Driver for Sustainable Development

The growth of renewable energy in the United States has brought benefits that transcend the environmental aspect, directly impacting the country's economic progress.
