Vacuum means an absence of matter, it does not mean an absence of energy.

From Wikipedia, the free encyclopedia
Vacuum energy is an underlying background energy that exists in space even when devoid of matter.
The vacuum energy results in the existence of most (if not all) of the fundamental forces - and thus in all effects involving these forces, too. It is observed in various experiments (like the spontaneous emission of light or gamma radiation, the Casimir effect, Van-Der Waals bonds, the Lamb shift, etc); and it is thought (but not yet demonstrated) to have consequences for the behavior of the Universe on cosmological scales.

The vacuum energy would have to be the energy of space.
Sometimes terms like false vacuum are used but they are words that attempt to explain phenomena that may not really exist.
