Half of all new data centers will explore heat reuse. Data centers use roughly 1 to 1.3% of global final energy consumption. Germany is debating a new law, the Energy Efficiency Act, that would require public authorities, corporations, and data centers to use less energy through practices such as heat reuse. Many believe that this is the first of many global laws in this regard. Heat reuse means utilizing excess heat from servers to serve energy demands outside the data center. In 2024, data center builders will preemptively invest in this practice to reduce cost and meet their own carbon commitments in anticipation of this new wave of legislation.
