Enhanced Geothermal Energy and Man-Made Earthquakes

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.

The Babson Boulders of Dogtown

In his 1905 book, The Protestant Ethic and the Spirit of Capitalism, German economist and sociologist Max Weber theorized that capitalism’s ascendancy owed much to Protestantism’s emphasis on hard work and worldly success. Whether or not Weber was actually right, the term he coined, “Protestant ethic,” has, to many, become accepted as part of our shared American definition.
