Datacenters have enriched the planet, making services like e-commerce and web search available to billions. However, the growing carbon footprint of datacenters adds to climate change and, in the long term, could harm society's perception of the whole field. Our ongoing work builds mechanisms for sustainable datacenters, i.e., datacenters that profit while maintaining low carbon footprints. Intellectually, the work contributes new analytic models that relate a datacenter's carbon footprint to its utilization and energy costs. These models must consider complicated issues like solar- and wind-energy outages, heavy-tail and diurnal e-commerce workloads, and workload and energy balancing within datacenters (e.g., dynamically powering servers off and DVFS). Further, the models must be holistic, explaining these factors in terms of profit. In terms of broad impacts, this work will improve the economic competitiveness and sustainability of datacenter-driven computing.

数据中心丰富了这个星球，为数十亿人提供了电子商务和网络搜索等服务。然而，数据中心不断增长的碳足迹加剧了气候变化，从长远来看，可能会损害社会对整个领域的看法。我们正在进行的工作是建立可持续数据中心的机制，即在保持低碳足迹的同时盈利的数据中心。在智力上，这项工作提供了新的分析模型，将数据中心的碳足迹与其利用和能源成本联系起来。这些模型必须考虑复杂的问题，如太阳能和风能的中断、重尾和日间电子商务工作负载，以及数据中心内的工作负载和能量平衡（例如，动态地关闭服务器和DVFS）。此外，这些模型必须是整体的，用利润来解释这些因素。就广泛的影响而言，这项工作将提高数据中心驱动计算的经济竞争力和可持续性。
