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

Solar water heaters work! Growing up we had one that heated our water before it went to the water heater and it saved a lot of money and electricity.
Also we had an outdoor solar shower at our place in Cascade that was great.
One of the first things I plan on doing when my wife and I move into our new home is build a solar water heater for our roof and insulate the attic much better.
Here is the basic design of a solar water heater system.

Can one of the engineer types on this list explain why heat exchange systems would or wouldn’t work in the typical mountain west environment?
