I will discuss the sensitivities of various future low energy neutrino experiments to generic non-standard neutrino interactions and to specific scenarios like extra neutral gauge bosons,
leptoquarks and R-parity breaking interactions.
The current limits,
other experimental proposals and astrophysical applications of non- standard neutrino interactions will be commented.
Finally I will present a new limit on the electron neutrino effective charge radius from a new evaluation of the weak mixing angle by a combined fit of all electron-(anti)neutrino electron elastic scattering measurements.
