We have 103 licensed nuclear plants, mainly in the eastern half of the US.
2957.94 MW of geothermal power are in current use. Alaska, California, Hawaii, Idaho, Nevada, New Mexico and Utah are the only states with geothermal plants. And of those, California ranks highest in MW output. Many of the plants though are small and not taking advantage of the existing potential. All of just these states are grossly underexploited for geothermal resources.

The comparison between the two is indeed laughable. Now lets look at the geothermal potential map, the POTENTIAL geothermal map of the western half of the US.
Yes, the whole point is that we need more geothermal plants, as many as nuclear, to make an accurate comparison. So let's get busy and bring the number of geothermal plants up to 103 nationwide and we'll do an accurate side-by-side comparison.
And of course it won't be a simple comparison, we will have to take into account the total actual costs of both types of power generation, including mining, if any, transportation, if any, safety, management, development and waste disposal, if any vs output and benefit to US citizens..
Then we can all make intelligent decisions. Since geothermal is so benign, we should already be at work bringing the number of plants up to at least 103 at full potential for the study proposed..
You do want it to be a fair comparison eh?
