# Earth as an energy source & sink

dear Physicists

An important thing that I had to clear my mind of is that of the energy
balance here on earth itself, so my question is :

1. Is it correct to generalize that KE, NucE, Heat that drives the
plant came from the earth ( as an E source) and that its final form
elctrical E can be discharge directly to earth or soil ( assuming no
load ) as part of the energy balance law ( earth as an E sink).

Some say that earth abosorbs electrons from space, if this true, then
it can be said the same for electrons coming from power lines short
circuiting to the earth or that of lightning.

from there I can make another conclusion that :

2. The earth is a big neutrally charged capacitor that electricity
coming to it one point will be counter acted or neutralized (
dissipated at that point)
but by law of E conserv. It will "discharge" electrons to the
distant plant, increasing currents inside the generator coils creating
counter magnetic fields forcing opposite torque to shaft.

Here it can be seen that the earth is sending energy which transforms
into different forms: recoverable - EME, KE and unrecoverable -Heat

Very interesting , I sure hope someone replies

Also , if the earths core is iron , and it is rotating inside the earths magnetic field , why isnt EMF created and where does it go if it is?

I suppose the lines of force may be rotating also so there is no work done with respect to the rotating core
