Great summary of geothermal options

Not too technical but explains in clear language the benefits , Ins and out with examples from personal experience

Plenty of tech info included along with references to more if desired

Reference point is 2010 so time for an update

Excellent, comprehensive, filled with the author's biases but also includes a lot of material to critically analyze those biases.
