This Letter describes the measurement of the energy dependence of elliptic flow for charged particles in Au + Au collisions using the PHOBOS detector at the Relativistic Heavy Ion Collider. Data taken at collision energies of √SNN = 19-6, 62.4, 130, and 200 GeV are shown over a wide range in pseudorapidity. These results, when plotted as a function of η′ = |η| - ybeam, scale with approximate linearity throughout η′, implying no sharp changes in the dynamics of particle production as a function of pseudorapidity or increasing beam energy.
