A simple energy balance of comet ejection from the Uranus-Neptune region is
discussed. If we assume that the orbits of Uranus and Neptune remain stable
during the ejection process, the necessary energy loss of perturbing planets
needs a compensation. Planetary perturbations leading to short-period orbits of
a part of comets are suggested as an explanation. Considerations about the
total energy conservation become more important if a high mass of Oort cloud is
