It is kind of hard to understand all you say, but right at the start you say gravity is energy, which seems a bit wrong to me, gravity is a force hence a manifestation of energy, but not energy itself.
I do also not see what you want to do with electricity and why electricity seems more important than other to you. And what do you understand under electricity?
That we are all made of energy, is nothing new since
...then the possible uses of this energy may be very many, but we have to figure them first ;-)
