Not today, but maybe someday.
(1) - The geothermal heat flow from the Earth's interior is estimated to be 47 terawatts
(2) - Human production of energy is even lower at an estimated 160,000 TW-hr for all of year 2019. This corresponds to an average continuous heat flow of about 18 TW

- ncmncm 5y agoNo, because the heat comes out regardless. The difference is whether it is used on the way out. Likewise for solar and wind.
- uranium 5y agoThere's the heat that comes out regardless, and the additional heat that comes out if you drill a bunch of boreholes down to let it out, accelerating the transfer. That being said, it doesn't look like we'll get to a significant magnitude of effect for a long time.
- derekdahmer 5y agoWow 47 TW of heat for the entire earth is so much lower then I ever would have guessed. The wiki says that its about .08W/m^2. That means it an area of 2-3 football fields only puts out as much heat as a single space heater.
