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.
Here's the information YOU consistently "tune out":

Note the location of the geothermal resources.
Now note the location of the population.
Now note that the vast majority of that population is greater than 700 miles from those geothermal resources.
I can' make it any plainer than that---geothermal energy is a typical "green boutique" project. It makes the greens "feel good" but it doesn't do much to solve environmental problems.
