The amount of energyy you get out of an engine or generator.
For a generator, you put energy into it in the form of chemical (coal, gas etc.) and you get energy out in the form of electrical energy. The net energy yield is the amount you put in minus the amount you get out. (always a negative number, you put in more than you get out.)

Essentially, it's the difference in the energy required to harvest an energy source and the energy that the source actually provides.
For example, you have to build an operate an oil well to pump oil - so you have to get a certain amount of oil to offset the energy reqired to run the well. Oil harvested above that amount is counted as net energy yield.

Hummm
you can research this answer yourself, and if your teacher gave you this question then you are smart enough to answer it by doing your OWN research.
In the interim
Go to Google:
Type in: What Is Net Energy Yield"
Hit"Search" key
You will see list of sites
Click the first one: Net Energy Yield
You will find answer there. Read entire article, and if needed, click on other related sites you will find there also.
or you can visit other sites on that page
OK?
