一句话：提出 Carbon Explorer 框架，用于权衡数据中心运营碳与隐含碳，并优化 24/7 无碳运行方案。
科技公司常通过可再生能源投资和购电协议获得抵扣，使数据中心在年度层面实现净零；但逐小时看，当无碳能源稀缺时仍会从电网消耗高碳电力。Carbon Explorer 是一个整体分析框架，用于探索 24/7 无碳数据中心的解空间。它综合考虑互补可再生能源、储能与工作负载调度，并按地理位置和工作负载在运营碳与隐含碳之间做权衡，优化 24/7 无碳运行方案。该框架已开源。
Technology companies reduce their datacenters’ carbon footprint by investing in renewable energy generation and receiving credits from power purchase agreements. Annually, datacenters offset their energy consumption with generation credits (Net Zero). But hourly, datacenters often consume carbon-intensive energy from the grid when carbon-free energy is scarce. Relying on intermittent renewable energy in every hour (24/7) requires a mix of renewable energy from complementary sources, energy storage, and workload scheduling. In this paper, we present the Carbon Explorer framework to analyze the solution space. We use Carbon Explorer to balance trade-offs between operational and embodied carbon, optimizing the mix of solutions for 24/7 carbon-free datacenter operation based on geographic location and workload. Carbon Explorer has been open-sourced at https://github.com/facebookresearch/CarbonExplorer.
