Abstract
A biological cell is drowned in the environmental energy ecosystem, which consists of matter-sourced conventional energy, information-sourced dark energy, and consciousness-sourced subtle energy. The stupendous work a cell does in its Gene machinery and the Protein factory using dark and subtle energy silently, without creating any pollution of the environment is remarkable in this respect. From the insights of cell biology highlighted in this paper, it seems there is a lot to learn from a cell to have a clean green energy ecosystem for humanity in this material world of machines.
