Energy - In physics, energy (Ancient Greek: ἐνέργεια energeia "activity, operation") is an indirectly observed quantity. It is often understood as the ability a physical system has to do work on other physical systems. Since work is defined as a force acting through a distance (a length of space), energy is always equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length. (source: Wikipedia) Energy generation, storage, and utilization in an efficient and sustainable way is one of the key issues facing any colony or rebuild issue. If the effort is connected to a larger civilization or is linking with other groups, energy distribution can be a major issue as well.
