Ok, but geothermal energy creates pollution. It's considered a cleaner alternative to tradition energy sources insofar as it replaces existing energy demands, not when the demand is being created ad hoc.
Building a new power plant in addition to all your existing ones will never reduce GHG emissions, regardless of how clean the new one is. We need to start tearing down old power plants and reducing consumption overall, not finding new things to spend countries' worth of energy on.
But I fail to see how geothermal's environmental impact is problematic.
Bootstrapping energy production in remote places could have a few nice side effects sure, it just doesn't help its environmental impact.
