You can have geothermal power everywhere if you drill deep enough
Something I've always wondered.<p>Wouldn't massive scale geothermal end up pumping <i>more</i> heat into the atmosphere that otherwise wouldn't be there?<p>In contrast, the energy collected by solar and wind generators is from the energy added to Earth by the sun and would be energy in our atmosphere regardless of whether  or not we collect it.<p>But it seems like the heat inside the Earth's core should be fairly well insulated by the lithosphere, and it only slowly leaks out over time. If we start pulling that energy out at a faster rate to generate electricity, could that have a noticeable net increase on total energy under the atmosphere, or is it such an insignificant amount of energy relative to the sun's to not even bother worrying about?
