Abstract：
The average plaquette energy E_p of U(1) Lattice gauge theory in 3 dimensions with an independent plaquette effective action is calculated using the variational cumulant expansion.The E-β curve is continuous,which shows that U(1) theory has only one confine phase.Our result is consistent with Monte Carlo data.
