ABSTRACT
The physical internet sounds like science fiction, but 3D printing came into its own during the first extreme COVID lockdowns and is increasingly used across many industries to produce short run parts or components too complex for normal production processes. As the core reason for doing an energy audit is identifying energy saving opportunities, this is where the rubber hits the road – often literally. Drones are also beginning to make an appearance whether on road or by air. I hope, for obvious reasons, air delivery will use more energy than road.
