Despite Trump's administration unwinding Biden-era clean energy subsidies, clean energy stocks have surged 130% since Inauguration Day, nearly matching semiconductor performance. The rally is driven by AI data centers' massive electricity demands and elevated oil prices from Middle East conflicts, making renewable energy economically attractive regardless of policy. Key winners include fuel cell and power electronics companies that now serve as AI infrastructure rather than climate policy bets.

The article compares two clean energy ETFs: iShares Global Clean Energy ETF (ICLN) offers broad diversification across renewable energy sectors with a lower 0.39% expense ratio and 1.20% dividend yield, while Invesco Solar ETF (TAN) provides concentrated exposure to solar companies with a higher 0.70% expense ratio. ICLN delivered better 5-year returns ($1,021 vs $806 on $1,000 invested) and lower volatility, making it suitable for broad clean energy exposure, while TAN appeals to investors bullish specifically on solar driven by AI data centers and electrification trends.

The article compares two hydrogen fuel cell companies: Bloom Energy, which focuses on stationary power systems for data centers and critical infrastructure, and Plug Power, which aims to build a vertically integrated hydrogen network. Despite Plug Power's lower valuation multiple, Bloom Energy is recommended as the better 2026 investment due to its positive free cash flow, strong revenue growth (130% last quarter), profitability improvements, and major partnerships like the $5 billion deal with Brookfield for AI data centers. Plug Power faces profitability challenges with a $1.6 billion net loss in FY2025 and negative free cash flow of $661.5 million.

The Vanguard Russell 2000 ETF is outperforming the S&P 500 with an 18% year-to-date gain, driven by domestic-focused small-cap companies benefiting from U.S. government policies and AI infrastructure demand. However, rising inflation and anticipated interest rate hikes pose a significant risk, as 32% of Russell 2000 companies carry floating-rate debt that will become more expensive, potentially hampering their growth and earnings.

The Russell 2000 index is reaching record highs driven by AI-related stocks rather than regional banks, which historically led small-cap rallies. Technology and industrial stocks account for over 70% of the index's year-to-date gains, with semiconductor, optical equipment, and data-center infrastructure companies surging. The AI trade has moved downstream to suppliers and builders supporting data-center buildout.

Bloom Energy stock has surged over 1,400% in the past 12 months and nearly 250% in 2026, driven by strong demand from data centers needing on-site power generation. Q1 2026 earnings showed record revenue of $751.1 million (up 130.4% YoY) and a return to profitability with $70.6 million in net income. However, the stock trades at a forward P/E of 147 with a beta of 3.8, indicating significant valuation risk and volatility. The company remains a long-term buy given the growing data center market expected to reach $699 billion by 2034, but investors must be prepared for price swings.

Despite Wall Street analysts maintaining bearish ratings on Plug Power with price targets implying 25-65% declines, the stock has surged over 350% in the past year. The article argues bears may be underestimating the company's potential to capitalize on the AI data-center boom, which requires massive clean energy infrastructure. However, the author acknowledges hydrogen fuel remains expensive and unproven, with Plug Power facing competitive disadvantages against rivals like Bloom Energy.

Plug Power stock surged 14.35% today despite no company announcements. The rally was driven by investor speculation following Bloom Energy's partnership with AI company Nebius to deploy fuel cell technology for data center infrastructure. Additionally, Plug Power showed improving financial health with Q1 2026 gross margins improving to negative 13% from negative 55% year-over-year.

Nebius stock surged 14.65% after announcing a strategic partnership with Bloom Energy to deploy fuel cell technology at its AI data centers. The collaboration aims to address the critical power bottleneck in AI infrastructure by providing clean, efficient energy with faster deployment timelines. The companies expect their first project with 328 MW capacity to begin operations later in 2026.

U.S. stock futures showed mixed performance on Thursday following Nvidia's strong Q1 earnings and positive Q2 guidance. While the Dow Jones and S&P 500 gained slightly, the Nasdaq fell modestly. Intuit tumbled 13.5% despite beating earnings due to announced workforce cuts, while e.l.f. Beauty surged 9% on better-than-expected results. Nebius Group and Bloom Energy rose after announcing a 10-year partnership for AI infrastructure deployment.

Nebius Group announced a partnership with Bloom Energy to expand its AI cloud infrastructure using fuel cell technology for clean energy solutions. The company reported explosive Q1 2026 growth with 684% revenue increase to $399 million and raised its contracted power guidance to 4 gigawatts by year-end. The first joint project is expected to be operational this year with 328 MW capacity. NBIS shares surged 8.40% in premarket trading.

Nano Nuclear Energy signed a Memorandum of Understanding with Super Micro Computer to explore co-packaged solutions for data centers. While the deal affirms the company's technology utility, it doesn't provide a clear revenue pathway or accelerate commercial viability timelines. The company won't have a working prototype for at least another year and isn't expected to reach commercial stage until 2030. Despite being well-capitalized with over $550 million in cash, the stock faces headwinds from a 30% short interest and competitive threats from more advanced small-modular-reactor companies and Bloom Energy's fuel cells.
