The AI tailwinds have really powered energy stocks over the past year, thanks to a looming surge in demand driven by new AI data centers coming online. Undoubtedly, it's not just the energy companies with AI data center partnerships in place that have won big. Even the heavy-duty machinery suppliers (think the turbine makers), vital for power production, have benefited greatly. Undoubtedly, the AI tailwind might not be so quick to fade for the energy companies that have gained significant ground in the past year.
