Well, since the link I provided was to an international company, and I posted a map showing world wide distribution of plants from one small company, one could easily have surmised you were referring to the world total.
Quibbling over "exceedingly rare" vs. "small number", not withstanding, you were also wrong that Geothermal plants need to be located near major urban areas. I have referenced you to numerous plants where this is not the case. I am not in my office and thus I do not have access to one of my books, which if I recall correctly lists the MW capacity of the USA (as of 2002) by fuel source and or Plant type. There are about 40 geothermal plants located in California and Nevada alone, a number which in all likelihood exceeds your original thinking, which I was first addressing.
And what percentage of all the urban areas of the USA does this dinky little figure represent??? 0.001%??
I'll say it ONE MORE TIME--the vast majority of potential geothermal sources are too remote from urban areas to be successsfully utilized. LOOK AT THE DAMNED MAP OF THE US. Probably 95% of the POTENTIAL (not practical) geothermal is west of the Mississippi River, while most of the population is east of the Missippi. You don't transmit electricity thousands of miles--not with current (no pun intended) transmission technology, you don't.

Judging from the ones you posted, the total output of geothermal energy in your list doesn't even meet the output of two standard nuclear power plants. Of course, it's hard to tell , given your "mixed units" including either megawatts or "number of homes" (a meaningless measure).
Geothermal will NEVER provide a significant portion of the US's energy needs. Better to spend the money and energy building a breeder fission capability.
