I exhibit the conflicting roles of Noether’s two great theorems in defining conserved quantities, especially energy in general relativity and its extensions: it is the breaking of coordinate invariance through boundary conditions that removes the barrier her second theorem otherwise poses to the applicability of her first. There is nothing new here, except the emphasis that general must be broken down to special relativity in a special, but physically natural, way in order for Poincaré or other global groups such as (A)dS to ‘re-’emerge.
