A covariant formula for conserved currents of energy, momentum and angular-momentum is derived from a general form of Noether's theorem applied directly to the Einstein-Hilbert action of classical general relativity. Energy conservation in closed and flat big-bang cosmologies including cosmic radiation and dark energy is discussed as special cases. Special care is taken to distinguish between kinematic and dynamic expressions.
Comments: 11 pages, this is an updated version of an earlier paper originally archived as arXiv:gr-qc/9701028. The cosmological constant has been added to the analysis, plus other small additions. Submitted to Prespacetime Journal.
