At the VEPP-4 accelerator complex experiments on high energy physics, nuclear physics, synchrotron radiation and hard X-ray are carried out. The paper presents the current status of the complex and its experimental programs. The development of the resonance depolarization method for the absolute beam energy measurement using a laser polarimeter is discussed. The results of observing the azimuthal difference of the orbits of electron and positron beams, which is a consequence of energy losses due to synchrotron radiation, are presented.
