From what I’ve heard you just need to let the reservoir “recharge” for about 30 years to get the heat back. So worst case you need to build twice as many geothermal plants. It’s not that different from nuclear power plants that need to be decommissioned after some decades… except you can just leave borehole and reuse it after a couple of decades or so.
It’s also better than drilling for oil/gas.. where you need to keep drilling constantly to get more oil/gas.
And as some here have pointed out, if there’s an excess of energy, which there will often be in a world with lots of renewables, you can pump heat back down into the reservoir, extending its lifetime.
So as always, at just comes down to cost. And I truly believe that if we put as much money into geothermal as we have with fossil fuels and nuclear power, it’ll be the cheapest and most environmentally friendly way of making power in a decade or two.
