In an earlier posting I noted that geothermal energy is best in moderate climate zones. I think I may have been wrong and should have said “temperate” climate zones. I am also a geothermal noob. But thank goodness for the internet.
I recently found a site focused on building awareness of the potential of geothermal energy:
The current production of geothermal energy from all uses places third among renewables, following hydroelectricity and biomass, and ahead of solar and wind. Despite these impressive statistics, the current level of geothermal use pales in comparison to its potential. The key to wider geothermal use is greater public awareness and technical support. http://www.geothermal.org/what.html
To remove your status of geothermal noob, check out this PDF from the University of Utah:
It looks like Nevada is geothermal central.
