Negative energy in physics can come in three forms:
(1) potential energy - this is the amount of energy one must exert in order to escape the potentia well, so it is considered to be negative energy.
(2) energy in any system below the conventionally-defined ground state. Examples are positrons under the dirac sea model of electron behavior, and the region of reduced vacuum energy associated with the Casimir effect.
(3) negative rest energy, which corresponds to negative mass. However, we have not yet discover negative mass in nature, even though its existence is theoritically possible.
