The article compares two energy stocks positioned to benefit from AI data center demand: Bloom Energy, which manufactures solid oxide fuel cell systems for on-site power generation with 85% projected revenue growth but high valuation multiples and profitability challenges; and Constellation Energy, the largest U.S. nuclear power operator with more modest but stable growth, strong cash flow, and lower valuation metrics. The author recommends Constellation Energy for long-term investors due to its reasonable valuation and reliable earnings, while cautioning that Bloom's history as a volatile stock warrants caution despite its growth potential.

Bloom Energy (BE) closed down 1.27% and has declined 11.36% over the past month, underperforming its sector. The company is expected to report earnings on October 22, 2026, with projected EPS of $0.71 (up 373% YoY) and revenue of $1.07 billion (up 106% YoY). However, the stock carries a Zacks Rank #3 (Hold) rating with a premium Forward P/E of 88.97 versus its industry average of 17.11, and recent EPS estimates have declined 0.68% over 30 days.

Bloom Energy is expected to report Q3 2026 earnings on October 22 with consensus estimates of $0.71 EPS (up 373.3% YoY) and $1.07B revenue (up 106.3% YoY). However, the company's Earnings ESP is -5.63%, indicating recent analyst downward revisions, making it difficult to predict an earnings beat despite a Zacks Rank #3 (Hold) rating and strong historical beat record.

AI data centers face a significant electricity shortage, with the U.S. alone projected to have a 32-gigawatt shortfall by 2028. The article identifies seven stocks positioned to benefit from this power crisis: utility companies with nuclear capabilities (Constellation Energy, NextEra Energy, Vistra), equipment manufacturers for power generation and management (GE Vernova, Bloom Energy, Eaton, Vertiv). These companies are capitalizing on growing demand for alternative power solutions and energy-efficient infrastructure.

Tesla secured an order for 260 Megapack 2XL units (1 GWh capacity) from Taiwan-based Apollo Power, with deliveries beginning late 2027 and operations in 2028. The deal highlights growing demand for battery storage in AI data centers. However, only 33 units have signed contracts while 150 remain under negotiation, limiting near-term revenue visibility. Tesla's energy storage business continues to grow with 13.7 GWh deployed in Q3 2026, but the company faces competition from Fluence Energy and Bloom Energy in the AI infrastructure power market.

Bloom Energy stock has surged nearly 1,000% over five years due to AI data center demand for its fuel cells, but is currently 31% below its June record at $239.34. The analyst forecasts the stock will trade around $230 by 2030 despite significant company growth, as current valuations at 90x earnings leave little room for upside even if earnings nearly triple. Key concerns include potential margin compression and the depletion of $2.3 billion in tax-loss carryforwards.

VanEck's NLR nuclear-focused ETF offers higher dividend yield (3.1%) but underperformed significantly with a 21.8% loss over the past year, while iShares' ICLN renewable energy ETF gained 11.0% with lower costs (0.38% expense ratio). The choice between them depends on investor priorities: NLR provides concentrated nuclear exposure but faces regulatory and interest rate risks, while ICLN offers broader diversification across 105 holdings in solar, wind, and clean energy equipment.

Plug Power (PLUG) fell 7.05% to $1.45 on October 14, 2026, following price target cuts from Susquehanna (from $2.50 to $1.75) and Morgan Stanley (from $1.65 to $1.20). The decline reflects concerns over hydrogen adoption headwinds, rising interest rates impacting debt obligations, and margin sustainability. The broader clean energy sector also declined, with Bloom Energy down 9.14% and FuelCell Energy down 8.65%. Investors await Plug Power's Q3 results on November 9 to assess progress on gross margin improvement and revenue growth.

The Global X U.S. Electrification ETF (ZAP), launched in December 2024, offers broad exposure to the Energy - Broad sector with a 0.5% expense ratio and $450.69 million in assets. The fund has gained 10.03% year-to-date and 7.52% over the past year, with heavy allocation to Utilities (70.7%). However, it carries a Zacks ETF Rank of 3 (Hold) and has more concentrated exposure than peers with 47 holdings.

Zacks highlights three top-ranked Nuveen mutual funds with Zacks Mutual Fund Rank #1 (Strong Buy): Nuveen Quant Small Cap Equity (TSCWX) with 21.4% three-year annualized returns, Nuveen Large Cap Value Retirement (TRLCX) with 19.2% returns and 0.65% expense ratio, and Nuveen Quant Small Cap Equity Retirement (TRSEX) with 20.6% returns. All three funds are expected to outperform their peers.

Bloom Energy, a high-growth fuel cell company serving AI data centers, shows strong 37% revenue growth but remains unprofitable with high valuation multiples. NextEra Energy, a mature utility giant, offers lower valuation, steady profitability, and a 3.2% dividend yield. The choice depends on investor risk tolerance: Bloom Energy suits aggressive growth investors, while NextEra appeals to value and income-focused investors.

Bloom Energy and Vertiv are two AI infrastructure plays that have recently pulled back. Bloom Energy focuses on fuel cell power generation for data centers, while Vertiv specializes in cooling systems. Vertiv's planned acquisition of UtilityInnovation Group expands it into on-site power and microgrids, offering more diversification. Bloom offers more concentrated upside if power becomes the key bottleneck, while Vertiv provides broader exposure to the AI infrastructure stack.
