Harry Reid Pushes Nevada As "Saudi Arabia of Geothermal Energy"
An anonymous reader writes "Of all the 'mainstream' forms of renewable energy, it seems that geothermal power is always left in the shadows compared to solar and wind power. However, that looks set to change with news that the US Department of Energy will fund geothermal projects in northwestern Nevada and southeast Oregon. With funds from the American Reinvestment and Recovery Act, the DOE has stated a 'conditional commitment' to provide a partial guarantee for a rumored $98.5 million loan to the Nevada Geothermal Power Company (NGP). According to US Senator Harry Reid, 'Northern Nevada is the Saudi Arabia of geothermal energy.'"
The problem with geothermal is that after you extract the heat from the rocks, it takes time for the surrounding rock to heat up the cool spot you've created. This places a natural limit on the rate you can extract heat energy from a geothermal well, thus making it unsuitable for high population density areas like cities. The geological formations in some areas provide their own natural flow of subterranean water, thus constantly carrying in heat from other distant rocks to your geothermal well. But those are exceedingly rare.
Regardless, I am very optimistic about geothermal for meeting the energy needs of low population density areas. On top of that, geothermal heat pumps for heating and air conditioning, while not an energy source, improve efficiency so much that in both hot and cold regions of the country, they will typically pay for themselves in 3-7 years.
Actually, as a resident of Reno (it's not as bad as it sounds.. really) I can definitively say that there is more geothermal energy over a wider area here than in Yellowstone. My understanding is that Yellowstone has a very strong, but very locialized pocket of usable energy, whereas the entire greater Carson-Reno area is tappable for energy. There have been quite a few apartment complexes and neighborhood groups who have pitched together to fund geothermal wells in this area, and effectively end up paying about 15k as a one-time cost to eliminate an electric bill for life (well, the life of the well, anyway). Best part is, because more energy is generated than can reasonably be used by 15-20 houses, the rest gets sold back to the electric company, and NV Energy takes care of maintenance on the well in exchange.
It makes me wonder, if Senators bring in pork to their state to get re-elected, do you think there would be more pork in general if we repealed the direct election of senators, which some claim would give states more say in the Federal government? As is I think the fact that so much party money is on the line to keep representatives 'pure', which greatly distorts the idea of local elections.

That's one of the things I always hated about politicians. They always think their state is the best
It's not a problem with politicians, it's a problem with the system. The constitution says that a senator represents a state, a congressperson a district. If you want it to be different, we need to have a body that is elected by the American people as a whole.

Sorry about that. O_o
Federally funded Nevada geothermal plant sponsored by Harry Reid triggers ... earthquakes ...
Not completely a joke.
High pressure injection of liquids into faults makes them act as hydraulic jacks with piston cross-sections measurable in square miles, pushing the faults open. If the faults are under even slight crosswise stress that cause earthquakes. (This was first discovered in Denver when the Rocky Mountain Arsenal used a deep injection well to attempt disposing of chemical warfare waste, later researched and documented.)
Doing it with a liquid that can boil when the rocks are hot means you have less control over the process once the liquid is in place and being expanded by the heat. (IMHO there's also a possibility of activating a volcano.)
While setting off quakes in northwestern Nevada probably won't bother the faults in San Francisco or Yosemite, it wouldn't be all that friendly to the people within a few tens of miles of the site.

The actual state most likely to qualify as a "Saudi Arabia of geothermal energy" is Wyoming. Remember the Yellowstone supervolcano? The caldera is tens of miles wide. We need to drill into the magma at a thousand places and extract heat, not only for the energy , but also because reducing the temperature down there relieves the pressure, and makes it less likely that the volcano will go off!
