I've looked at the map. I think you need to spend a bit more time doing so. Geothermal is useful in a very SMALL portion of the area of the United States, and accessible to only a tiny fraction of the population. Thus it won't ever make up a significant fraction of the total energy usage of the country--and in fact is probably not even capable of supplying the total electric needs of the area you mention.
I note you never did answer the question of what is the likely total DEVELOPABLE geothermal potential even of California. I also noted in passing through various online geothermal energy references that they can't even run the full installed capacity of "The Geysers", I assume because they were depleting the available resource.
You need not assume that. If you had been paying attention to my posts you would have seen that I said that much earlier in this thread.
But I think you only listen to what you want to listen to and tune out much of everything else.
