Abstract
In this paper, we provide a suitable theory for the energy
where μ is a Radon measure and Γ is the fundamental solution of a sub-Laplacian 
on a stratified group 
As a significant application, we prove the quasi-continuity of superharmonic functions related to . The proofs are elementary and mostly rely on the use of appropriate mean-value formulas and mean-integral operators relevant to the Potential Theory for .
