Well, so far, Cactus, your idea, which I took the liberty of plagarising, hasn't met with too hot a reception:
Renewable Energy And/Or Resources Board:
Check out this DOE website
http://www1.eere.energy.gov/geothermal/ That outfit from Provo, Raser, that used low heat for geothermal energy is building an 11 MW plant in New Mexico. Also our government is soliciting customers for $10 Billion dollars worth of loan guarantees for renewable energy projects. A loan guarantee isn't exactly like a grant but it can sure push financing costs down. I gotta wonder what geothermal resources we have in the Logan general area.
http://geothermal.inl.gov/maps/ut.pdf shows at least one hot well. Lgoan is shown as a potential geothermal area.

Chris et. al.:
Logan does not have a great potential for geothermal. As you may know Box Elder has some potential, but until an exploratory well(s) are drilled it is just speculation.
However, Logan can look to getting Geothermal Power from the other upcoming projects in Utah. Namely the Cove Fort (Enel North America Inc.), which may go on line in 2011. Pacificorp maybe doubling production (32 to 64MW) from the Blundell site in the next couple years and Raser is developing more just south of Milford. Utah.
Logan will just have to pay more then it currently does for old coal. However, It will be competitive with Natural Gas and prices will not increase due to fuel prices.
Don't forget it is baseload power.

"Logan does not have a great potential for geothermal. "
It might do to re-evaluate that in light of claims of technologies being able to produce power economically with less temperature differential than was traditionally considered necessary. (Yes, I'm aware of the laws of themodynamics where efficiency = delta T / T. Yes, we'd do well to be skeptical of the claims made.)
I mention this, because I've recently read "Earth, the Sequel, the Race to Reinvent Energy and Stop Global Warming" by Fred Krupp and Miriam Horn.
In chapter 7 the book describes this eccentric tinkerer entrepenuer by the name of Bernie Karl. He's had the distinction of being mentioned in Forbes for having come up with the "dumbest business idea of the year" back in 2004. His venture, to carve the six-room Aurora Ice Hotel out of fiftenn thousand tons of ice and snow in Chena, Alaska. Bernie's team embedded refrigeration tubing in an insulated exoskeleton to circulate glycol cooled by Caterpillar-built diesel generators at a cost of $700 a day. It didn't work. Within a few months of its January 2004 opening, the hotel was melting down. "I had a frozen asset, and I turned it into a liquid asset," Bernie joked with a reporter.
Some guys just don't know when to quit. He'd heard about claims of physicist, Don Erickson, who claimed to have come up with a three-pressure geothermal absorption chiller (most operate at only one pressure). Bernie applied this concept to tapping into Chena hot springs for providing the refrigeration to cool his next ice hotel venture. Bernie's absorption chiller was the first three-pressure chiller in the world to use geothermal energy. By all rights, that second system should also have failed; numerous experts assured Bernie he was just throwing more money away. Instead, the system worked.
From that success, Bernie got the attention of United Technologies Corporation, a $48 billion Fortune 500 company, which wanted to apply aspects of Bernie's contraption to modify its "PureCyle 200" power plant developed to make electricity from waste heat.
UTC is now building 225 KW power plants based on the three-pressure concept for commercial sale, while continuing work on a 1 MW plant. More than half of the first year's production has been sold to Raser Technologies, a Provo, Utah, based company that holds geothermal leases on 14,000 acres in Utah and will use 135 plantes to produce 30 MW of electricity.
I'm just wondering is all. Would it pay for the City of Logan to give Raser Technologies a call?
