Analysis

The clean energy sector is experiencing a significant rally in 2025, with the iShares Global Clean Energy ETF (ICLN) returning 46% year-to-date, notably eclipsing the Nasdaq's 20% rise and Nvidia's 38% gain. This strong outperformance coincides with renewable energy surpassing coal in electricity generation and California sourcing 66% of its energy from clean power.

A key driver for this acceleration is a federal "megabill" mandating clean energy project commencement by July 2026, inadvertently sparking a national manufacturing race. This regulatory push has led Bloomberg NEF to increase its power generation forecast by 10%. The global energy transition, valued at $110 trillion, is clearly underway, with solar becoming the EU's largest power source.

NextEra Energy (NEE) demonstrates robust fundamentals, with 25% earnings growth and 10.4% revenue growth last quarter, alongside a 33.8% operating margin, double the utility average. Its consistent 10% annual EPS growth and dividend increases since 1994 underscore stability. First Solar (FSLR) shows strong growth, with shares up 38% YTD, an EPS beat of 19.55%, and a gross margin increase to 46%, while maintaining an attractive P/E of 20.6.

For diversified exposure, the iShares Global Clean Energy ETF (ICLN) offers a broad play on the sector, tracking approximately 100 securities with a low expense ratio of 0.39%. Its significant allocation to utilities (over 50%) provides a degree of stability and income potential within the volatile clean energy landscape.

Key Decisions for Investors

• Consider increasing exposure to the clean energy sector given its strong outperformance and favorable policy tailwinds.
• Evaluate individual companies like NextEra Energy (NEE) for stable growth and income, or First Solar (FSLR) for high growth potential and attractive valuation.
• For diversified, lower-volatility exposure, the iShares Global Clean Energy ETF (ICLN) presents a viable option, particularly with its utility-heavy holdings.
• Monitor regulatory developments, specifically the July 2026 deadline for clean energy projects, as this will continue to shape the sector's near-term trajectory.
