Unprecedented Investment in Renewable Energy Breaks Records

The first half of 2025 marked a historic milestone in the global energy transition, with investment in new renewable energy projects soaring to an all-time high of $386 billion—a 10% increase year-on-year, according to the latest Bloomberg New Energy Finance (BloombergNEF) report. This unprecedented level of funding underscores growing investor confidence and highlights the accelerating shift toward a cleaner, more sustainable global energy system.

Renewable projects benefiting from the surge include offshore wind, small-scale solar PV, and innovative storage solutions. However, the rise in overall investments disguises a nuanced landscape with a decline in financing for large utility-scale solar and onshore wind projects, particularly in regions with shifting policy incentives.

Drivers Behind the Surge

The investment boom is primarily driven by two factors:

• Offshore wind reached a record $39 billion in the first half of 2025, surpassing the entire 2024 yearly total of $31 billion as governments and companies deploy massive projects worldwide.
• Small-scale solar projects, especially rooftop systems and distributed generation, saw nearly doubled investment in major markets like Mainland China as these fast-to-deploy systems allow investors to get ahead of policy changes impacting returns.

These trends reflect a pivot to project types that minimise regulatory risk and capitalise on evolving corporate energy demand and public support for decarbonisation.

Regional Dynamics and Emerging Markets

China retained dominance as the world’s largest renewable energy market, attracting 44% of global new investment during the period. Despite this, investment in utility-scale solar in China declined sharply by 28%, linked to increased exposure to volatile prices, prompting a shift toward smaller, distributed solar projects.

The EU-27 region posted robust growth, adding nearly $30 billion (63% increase) compared to late 2024, largely driven by offshore wind and smaller solar investments, supported by stable policy frameworks and ambitious climate targets. Europe’s surge suggests a major realignment of capital away from the US, where investment fell by 36% due to changing federal policy and tariff uncertainties.

Emerging markets like Southeast Asia and Latin America maintained or slightly increased their shares, with Latin America seeing record regional shares of capital inflows despite global volatility.

Challenges for Large-Scale Projects

While total renewable investment surged, finance for utility-scale solar dropped by 19% and onshore wind fell 13% year-on-year due to revenue uncertainty, project curtailment risks, and changing auction landscapes—particularly in China, Spain, Greece, and Brazil. Analysts highlight a “boom-bust” cycle where investors retreat from markets with unstable policy regimes toward those offering secure revenue mechanisms.

The Role of Innovation and Diversification

Renewable energy’s future rests on diversification and innovation. The investment spike in offshore wind and small-scale solar is complemented by growing interest in technologies like battery storage, green hydrogen production, and grid digitisation. Projects combining solar with storage systems and those optimising energy use through digital platforms are gaining traction, offering more resilient and integrated clean energy solutions.

What This Means for Global Decarbonisation

Record investments demonstrate the rising economic opportunity and urgency of renewables in countering climate change. Fueled by policy support, corporate demand for clean power, and declines in technology costs, the clean energy sector is increasingly able to drive down greenhouse gas emissions while fostering economic growth and energy security.

For the UK and Europe, this wave of investment means accelerated deployment of solar, wind, and battery systems vital to meet net-zero goals. It also signals a shifting global leadership landscape favoring regions with stable, visionary climate policy frameworks.

How Businesses and Homeowners Can Benefit

The investment wave translates to rapidly improving technology availability, quality, and affordability for solar PV, battery storage, and heat pump systems available to UK consumers. Companies like Atlantic Renewables are perfectly positioned to guide homes and businesses through this evolving market by offering bespoke clean energy installations aligned with emerging market innovations and incentives.
