Run the sim. Hold down the Alt key while the cursor is hovering over the supply source. You should now see a thermometer cursor. Left click to plot the supply source power.

After the power is plotted as Alec said, you can CTL left-click the plot title to display the average power over the simulated time interval.

There is another way to calculate the efficiency of the circuit and the loss on each element of the circuit. Download your schema with non-standard models and symbols, if it's not a secret. Better zip-archive. And I will demonstrate this method
