I've heard it is possible to extract energy into a power cell, from the earth's gravity only? Is it true?

Dams are a source of energy produced by gravity.
I think you will have to tap your hydro grid, it will be easier than building a dam!

Yeah, sure but oil's a much more effective source of energy.
