Energy Bank

The Energy Bank is a building that stores MetaJoules that can be used later.

Each Energy Bank stores 1000 MetaJoules.

Official Description
"Energy Banks are used to store additional MetaJoules that cannot be held by the Matter Converter. Energy Banks are small structures that are cheap and lightly armored, and do not require any men to operate them. Because they are slightly armored, it's usually a good idea to place these structures well within your Base where they can be easily defended."
