It's a little easier to tap geysers and lava flows near the surface for heat
energy and supply 300,000 people, than it is to tap the earth's crust at a
much thicker point in the US to supply 300 million.

I don't know where or what you get these numbers. Meaningless when 6
billion and rising are considered...
Best, Dan.

It's a bit easier for Iceland to provide energy for it's 300,000 people
derived from geothermal sources that are abundant and accessible.
Transferring that process to the 300 million Americans is not worth
considering. One private interest tried drilling into geothermal sources
near Yellowstone Park, affecting one of the nearby geysers. Much was made
of the damage to a national treasure and stiff fines were levied.

The geothermal resources of Iceland are not that accessible, you have
to drill into the earth a fair bit and the best results are likely to
be realised if you drill to a depth of 5 000 meters.

There are sources of geothermal energy elsewhere in the USA as well,
the state of Washington is probably the one with the largest amount but
there are other places as well.

The Southampton (UK) Geothermal project is not that deep (1.8km) and is
producing some useful (although non-renewable) energy. This link describes
the scheme. http://www.bbm.me.uk/portsdown/PH_450_Energy.htm
