Microsoft and Amazon are planning to transform aging coal and gas power plants across Europe into AI data centers. These facilities offer ideal infrastructure, such as electricity and water access, crucial for cooling and power stability. With AI's rising energy needs, European energy companies like RWE, Engie, and Enel see this as a profitable opportunity. Repurposing old plants avoids costly shutdowns and supports long-term green energy contracts. This approach could ensure reliable power for tech firms while aiding the transition to sustainable infrastructure.
