Operational technologies, or OT, are a critical segment of the network used by businesses that produce goods or engage in physical processes. Industries such as manufacturing, chemical, oil and gas, mining, transport and logistics use specialized technologies to manage facilities: Assembly and production sites and power systems. The control, monitoring, and management of these systems have been gradually automated over the past few decades, and the specialized systems that perform these tasks are called industrial control systems (ICS), dispatch control, and data acquisition (SCADA), or simply OT.

How sustainable is an industry that spends more on providing electricity to rotating fans than it does on powering processors?
