I don't think the energies will be very different from hydrogen bonds
in other molecules. Some hydrogen bond geometries are obviously
much more common than others (e.g. alpha helix backbone). 

McDonald and Thornton (J.Mol.Biol. 238:777-793, 1994) name "20kJ/mol"
as the interaction energy of an average inter-molecular hydrogen bond.
This paper contains many more interesting statistics about hydrogen bonds
in proteins.
