Visiting The Geysers geothermal plants

A steam well at The Geysers

 

 

 

 

I just returned from a research trip to The Geysers, a group of geothermal power plants in northern California.  Geothermal energy of the sort produced at The Geysers–electric turbines powered by steam harvested from natural hotspots beneath the Earth’s surface–may be limited to areas of geothermal activity, but it’s an intriguing source of renewable power–one that doesn’t get much attention compared to wind, solar, biofuel, and other more visible renewables.

The photo above is of a geothermal well sunk about a mile underground.  I’ve posted more pictures of The Geysers at www.renewablebook.com.  Take a look.
