13. A method of operating a rig, comprising:
operating a first rig component at a first location;
capturing waste energy from the first rig component at the first location; and
redirecting the waste energy to a second rig component, a second location, or a combination thereof, wherein a control system is configured to redirect the captured waste energy to the second rig component in response to a measured capacity of the captured waste energy exceeding a predetermined threshold capacity, a measured temperature of the captured waste energy exceeding a predetermined threshold temperature, or a combination thereof, or wherein the control system is configured to cease redirection of the captured waste energy to the second rig component in response to a measured capacity of the captured waste energy falling below a predetermined threshold capacity, a measured temperature of the captured waste energy falling below the predetermined threshold temperature, or a combination thereof.
