The Power Behind the Cloud: Data Centers, National Energy, and What's Next (medium.com)

Data center energy use is moving from a tech-industry footnote to a national infrastructure issue: U.S. data centers consumed roughly 176 TWh in 2023 (≈4.4% of U.S. electricity) and are projected to draw 325–580 TWh by 2028 (≈6.7–12%). That surge—fueled largely by AI training, cloud services, edge computing, and massive storage—creates concrete risks (grid stress, higher rates, supply-chain and permitting bottlenecks) and environmental impacts (about 56% of 2023 data‑center electricity came from fossil sources, plus significant water use for cooling). For the AI/ML community, this matters because AI workloads are both a major driver of demand and a key tool to mitigate it. Practical levers include integrated planning with utilities, stronger demand‑response programs, on‑site renewables and microgrids, battery storage, and reforms in permitting and rate design to discourage peaky loads. Technical measures—liquid cooling, underground thermal storage, higher server utilization, waste‑heat reuse, modular scaling, and AI-driven workload scheduling—can dramatically cut energy intensity. Policymakers and operators must also push for transparency, third‑party audits, and equity-aware siting. If handled proactively, data‑center growth can catalyze cleaner grids and innovation; if not, it risks undermining reliability, climate goals, and economic fairness.
