How long to exhaust even geothermic resources?

[Duckster]

Geothermal power is considered to be sustainable because any projected heat extraction is small compared to the Earth’s heat content. The Earth has an internal heat content of 1031 joules (3·1015 TW·hr).[3] About 20% of this is residual heat from planetary accretion, and the remainder is attributed to higher radioactive decay rates that existed in the past.[1] Natural heat flows are not in equilibrium, and the planet is slowly cooling down on geologic timescales. Human extraction taps a minute fraction of the natural outflow, often without accelerating it.

The hamsters quite understandably eat the carets when importing such data.

Rats - I was hoping we could finally cool this thing off and drill down to the center, the way Hollywood has been promising.

To answer the OP: probably well into the billions of years.

…enough power to finish typing this sentence?
