Energy

From CC Wiki

Energy is used to power buildings in The Space Game and TSG:M. It is an essential resource necessary to beat the game, together with minerals. Energy is generated by Solar Stations, then relayed to other structures via energy relays. Each structure can hold some energy for its own use, but this store will not last for more than a few seconds. When a structure's energy store is depleted, it will become inactive and turn red. Therefore every building needs to be connected to some kind of energy source to be functional.

Energy can also be stored in vast quantities in Energy Stores. When there is overcapicity these will slowly fill up, to be used when there is scarcity. This can be useful for large energy users, such as cannons.
