This article considers the quasi-local energy in reference to a gen- eral static spacetime. We follow the approach developed by the authors in [7, 9, 19, 20] and define the quasi-local energy as a differ- ence of surface Hamiltonians, which are derived from the Einstein- Hilbert action. The new quasi-local energy provides an effective gauge independent measurement of how far a spacetime deviates away from the reference static spacetime on a fnitely extended region.
