Omp Amp Non-Inverting Question

Maybe I'm still remembering what I learned from physics which "the energy you get equals the energy you put in." But I was looking at basic examples of non inverting omp amp examples but can it really amplify the current or voltage you put in? Is it really the case?

Actually there is always a loss, it's called entropy. Anyway you can never get more energy out than you put in.

An OpAMP uses external power to multiply an incoming voltage. It's called Gain. 1:1 is Unity Gain.

So let say I plugged an omp amp into a 5v supply, and I set up a non inverting circuit with a voltage gain of 10 and the input voltage is 1.5 volts then the output voltage will not be 15v?
