what form of energy do people use?
&
also doesnt E=mc squared mean energy=mass times ? squared....
&
how does increasing height affect gravitational potential energy?

1. Most folks use thermal energy a lot, and electrical energy second.

In the conversion of mass to energy, energy= mass*speedofLight^2

GPE= mass*g*height so increased height means more GPE
