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.
