• The unit of measurement for energy in the International System of Units is the joule.
• Forms of energy include the kinetic energy of a moving object, the potential energy stored by an object, the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, the internal energy contained within a thermodynamic system, and rest energy associated with an object's rest mass.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Energy article was read about 360,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 84 and blocks with 92: each hit it takes is cut by 37 %.
