Overview Our mission is to make renewable energy a global superpower by using computing as a catalyst. We develop, own, and operate digital infrastructure for energy-intensive computing applications by colocating data centers with renewable energy power plants. We refer to this model as Renewable Computing . Renewable Computing is designed to address two converging market conditions: increasing curtailment of renewable energy generation and growing demand for power-intensive computing applications, including artificial intelligence ( AI ), high-performance computing ( HPC ), and Bitcoin mining. By locating our data centers near renewable generation assets, we seek to convert underutilized energy into economically productive computing capacity. We utilize two distinct data center designs to serve different computing markets. For our Bitcoin mining and hosting business, we deploy a modular data center design optimized for flexible, large-scale digital asset operations. For AI and HPC workloads, we are developing an AI-ready data center design intended to support higher-density compute environments and customer requirements associated with advanced computing infrastructure.
