Anti-particles annihilate particles resulting is purely positive energy.

Does that mean following convention that anti-energy annihilates energy leaving nothing?

That is true for potential energy. We can define zero potential energy at any point in space in a gravitational field, like the surface of the earth. Then massive objects above the level of the earth have positive potential energy and objects below the level of the earth have negative potential energy.

If we do work to bring an object with negative energy up to the level of the surface of the earth, then the potential energy of the object becomes zero.

In a sense we have annihilated its negative energy or anti-energy by supplying positive energy. Is this what you mean by anti-energy?
