  In the recent years important discoveries in the field of low energy neutrino
physics (E$_\nu$ in the $\approx$ MeV range) have been achieved. Results of the
solar neutrino experiment SNO show clearly flavor transitions from $\nu_e$ to
$\nu_{\mu,\tau}$. In addition, the long standing solar neutrino problem is
basically solved. With KamLAND, an experiment measuring neutrinos emitted from
nuclear reactors at large distances, evidence for neutrino oscillations has
been found. The values for the oscillation parameters, amplitude and phase,
have been restricted. In this paper the potential of future projects in low
energy neutrino physics is discussed. This encompasses future solar and reactor
experiments as well as the direct search for neutrino masses. Finally the
potential of a large liquid scintillator detector in an underground laboratory
for supernova neutrino detection, solar neutrino detection, and the search for
proton decay $p \to K^+ \nu $ is discussed.
