Answer to Question 1

A thermal kilowatthour is the amount of thermal energy required to produce one
kilowatthour of electricity, which is 3 times as much. An electric kilowatthour is one
kilowatthour of electricity.

Answer to Question 2

The basic reason that there are more neutrons is to shield protons from one
another. It has nothing at all to do with size.
