Goethermal; squeaky clean or nukular-lite?
See the map in the link to note how close is the Petratherm project at Paralana to the Beverley uranium leaching project

I'm betting both 'carbon neutral' NZ and the Surat Basin coalbed methane use some kind of bogus carbon credit to get the guernsey.
Geothermal is an unproven technology which has defied the efforts of science since 1972. The USA and UK gave up and closed down their research facilities years ago.
The cost of drilling is the single biggest cost involved and after spending some millions reaching the hot rocks you have to hope the subsurface water loop flow rate is sufficiently fast (75kg/sec) and the temperature sufficently high (200C min.) to heat the power station loop fluid to make the steam to turn the turbine to make the electricity.
If the subsurface water loop flow rate or temperature drops due to underground reservoir problems you are in big poo-poos.
It might be made to work but then so might cold fusion.
