Abstract: We study the energetics of the accretion-induced outflow and then plausiblejet around black holes-compact objects using a newly developed disc-outflowcoupled model. Inter-connecting dynamics of outflow and accretion essentiallyupholds the conservation laws. The energetics depend strongly on the viscosityparameter \alpha and the cooling factor f which exhibit several interestingfeatures. The bolometric luminosities of ultra-luminous X-ray binaries e.g.SS433 and family of highly luminous AGNs and quasars can be reproduced by themodel under the super-Eddington accretion flows. Under appropriate conditions,low-luminous AGNs e.g. Sagittarius A^* also fit reasonably well with theluminosity corresponding to a sub-Eddington accretion flow with f\to 1.
