New geothermal plant in Utah will send 7 megawatts of power to California-
This is what should not be done. Seven megawatts, relatively speaking, is nothing. Most coal and nuclear plants are built in 300 to 1000 megawatt units. At any rate, small sources like this should be used locally.
One good thing about this is that it is a technological advancement. In the past geothermal electricity generation has required very hot water. This one does not.
I fear most hot springs are going to end up becoming an industrial site.

I think the ultimate beneficial use of geothermal energy will come when technology allows us to tap the heat of the Earth using the heat gradient as you drill down. This way, geothermal power could be tapped anywhere on the planet. Ralph Maughan
