Road Trip 2015: Sonoma County to Trinity Center

— 10:27 pm · One comment

Blue HighwaysIn 1982, I read Blue Highways, a bestseller written by William Least Heat-Moon. It chronicled a journey by car taken entirely on the small roads—the mapmakers’ blue highways. An English instructor as a small Missouri college, Least Heat-Moon, disoriented by a fracturing marriage, chose to look for himself by choosing, as Paul Simon put it, to “look for America.”

Buoyed by Least Heat-Moon’s adventures and observations, I have, whenever practicable, chosen those blue highways for my travels: a two-laner and small towns versus hurtling through interchangeable Interstate spaces at 70 mph.

So, for our road trip to Ann’s high school reunion in Casper, WY, I planned to include back roads whenever possible.

Day #1 was to begin at our home in Sonoma County’s Wine Country and end  Continue reading “Road Trip 2015: Sonoma County to Trinity Center” →

Is the Production of Geothermal Energy in The Geysers a “Public Nuisance”?

— 10:21 am · View all 3 comments

On September 15, less than a fortnight after AltaRock Energy halted its geothermal drilling in The Geysers, the Anderson Springs Community Alliance (ASCA), a small but formidable opponent of the AltaRock project, fired another salvo: this time charging the area’s main producer of geothermal energy with a public nuisance.

In a formal complaint and petition addressed to the Board of Supervisors of Lake and Sonoma Counties for “Remedy of Ongoing Public Nuisance from Geothermal Earthquakes Caused by Operations of Calpine Corp./Geysers Power Company, LLC at The Geysers,” ASCA specifically cited a September 5 magnitude 2.8 earthquake as the latest of more than a thousand magnitude 2.0 or higher temblors epicentered within five miles of Anderson Springs since 2000. These, ASCA contends, constitute an ongoing public nuisance. [A link to the complaint will be posted here when it goes online.]

According to the complaint, “Most residents of Anderson Springs were awakened by the jolt and noise of this earthquake; many were Continue reading “Is the Production of Geothermal Energy in The Geysers a “Public Nuisance”?” →

Enhanced Geothermal Energy and Man-Made Earthquakes

— 11:29 pm · View all 5 comments

Drill down just a few miles into the earth’s crust, and the temperature will rise substantially. This heat comes from three sources: emissions from radioactive minerals, the compressive force of gravity, and to a lesser extent, solar energy absorbed at the earth’s surface. Although such energy is not truly renewable (radioactive elements do eventually decay to energy-flat states), within any reasonable estimate of mankind’s tenancy on this planet, geothermal power is essentially limitless.

There are several techniques for transducing this energy from underground heat to in-the-grid electricity. One of these, a technology called Enhanced Geothermal Systems (EGS), is currently being tested by Sausalito-based AltaRock Energy only 12 beeline miles from my home in Northern California.
