Power is defined as energy E (or work W) emitted or expended over a time \Delta t, P = {\Delta E\over \Delta t}. For an energy flux S, the power passing through a surface S is given by the surface integral P = \int_S \mathbf{S}\cdot d\mathbf{a}. ...

is the rate of doing work or the rate of using energy, which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts.
