Clean energy is no longer just a policy theme, it's becoming a source of alpha

After years of uneven performance, clean energy assets have re-emerged as a standout investment theme, as capital shifts toward decarbonization and electrification, clean energy assets are delivering returns that outpace broad market benchmarks, underscoring their growing relevance in long-term portfolios.

In 2025, global clean energy investment reached a record USD 2.3 trillion, multiple clean energy thematic ETFs generated 12-month total returns in the range of 25%–32%, significantly outpacing the S&P 500’s return of 16.39% without dividends over the same period (ending December 31, 2025). This performance differential reflects deepening investor interest and structural tailwinds behind renewable power, energy storage, and efficiency technologies.

Clean energy stocks and ETFs have not only rallied on policy clarity and technology cost declines but also benefited from surging demand for electricity from electrified transport and data-intensive industries. The broader clean energy ecosystem supports this performance with sustained capital flows.

Global investment in renewables, EV infrastructure, and grid modernisation reached record levels in 2025, with early data indicating hundreds of billions of dollars deployed in clean technologies worldwide. In the U.S., the clean energy market was valued at approximately USD 85.7 billion in 2023 and is projected to be near USD 198 billion by 2033, implying a CAGR of ~9% over the next decade. Policy and industrial strategy remain powerful tailwinds.

Grid modernization, domestic manufacturing incentives, and long-term climate commitments have reduced revenue uncertainty across solar, wind, and battery storage. At the same time, corporate power purchase agreements and data-center-driven electricity demand are creating durable offtake for clean power producers.

Looking ahead, the U.S. clean energy market is projected to grow from under USD 100 billion earlier this decade to nearly USD 200 billion by the early 2030s, driven by record renewable deployments and advancing technologies. While volatility will remain, the investment case has shifted from policy optionality to fundamentals. For investors, clean energy is increasingly less about ideology and more about earnings visibility, infrastructure-like growth, and long-term alpha generation.
