The general features of the electrostatic oscillations in a lossfree plasma are discussed from the dispersion relation and energy equation. It is shown that the electrostatic waves in a lossfree plasma have always zero energy density, and negative kinetic energy density, the magnitude of which is equal to the electrostatic energy density. The feedback stabilization for reactive instabilities is reconsidered by a simple model, and a cold electron plasma-beam system is studied as a simple example.
