In general, the concept of energy refers to "the potential for causing changes". The word is used in several different contexts. The scientific use has a precise, well-defined meaning, whilst the many non-scientific uses often do not. (see here.)
In physics, energy is the ability to do work and has many different forms (potential, kinetic, electromagnetic, etc.) No matter what its form, physical energy has the same units as work; a force applied through a distance. The SI unit of energy, the joule, equals one newton applied through one meter, for example.
