    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

    Over the past few years, I've heard a little bit here and a little bit there about geothermal heating and cooling. I thought it sounded cool, but I didn't understand it. I was at the library and saw this book in the New Books section and grabbed it. I'm glad I did because now I have a better understanding about how this works. I hope I get to tour some homes and/or businesses who employ this amazing system soon.

I thought it sounded cool, but I didn't understand it. I was at the library and saw this book in the New Books section and grabbed it. I'm glad I did because now I have a better understanding about how this works. I hope I get to tour some homes and/or businesses who employ this amazing system soon. The author helped me understand how a geothermal energy unit works by first explaining how a refrigerator works. A refrigerator takes the heat out of the unit and releases it back into the kitchen (or wherever you have your fridge.) By understanding the job of the refrigerant, the converter, the coils and the placement of your fridge, you can get a basic understanding of how geothermal energy units work. Think of what your fridge does and then imagine your house as a fridge. Now add the coiling/looping under your property and a furnace inside your "fridge/house" and you can sort of imagine how it works. Then he explained the different ways of looping energy from the earth's source into and out of your home. There are several illustrations about the different loops (open, close, vertical, etc.) and the author also includes many different examples of different homes across the country. He also includes businesses (the Juneau, Alaska airport, a hospital in Chicago, IL, etc.) that use geothermal energy. The author wrote about the obstacles, caveats, quirks, learning curves and surprises. Positioning of the unit is important. Depending on where your unit is facing, you may need more electrical back up. Choose your looping process carefully. The underground sensors and systems are complex, so it is important to have a trustworthy contractor and sub-contractor. Some states and co-ops require a back-up furnace. You have to change your filter (like you do a regular furnace) or things will go wrong. Geothermal energy is very quiet, notoriously so, so many people weren't sure if it was working when the first cold front hit. Some people miss the old-fashioned Honeywell dial thermostat. I sum up these points for myself so I can remember them in the future. I sincerely hope the aforementioned list does not dissuade anyone. It is an initially expensive long term investment. Costs vary, but $30,000 is a fair number to put in your head as a beginning number. That is a big number, but the return is more than significant. Users will benefit from tax credits, low energy costs, increased home value, and a certain satisfaction in knowing they are doing something better for the environment. He also mentions that one of the perks is bragging rights, which annoyed me. Whenever anyone does anything to look cool, I find them to be anything but. He did well to help me get a basic understanding of geothermal energy, but he bragged too much about his accomplishment. I found myself thinking, "We get it, Lloyd" several times throughout the book. But so what. I am still thankful for the book because it helped me understand the technology. To sum up, to understand how valuable I think geothermal energy is please know that I have a 1991 Oldsmobile station wagon. It is paid in full and is a reliable vehicle, but it is ugly, is 20 years old and has been known to make terrible "clapping fart" sounds. I see the looks that people give us. Rather than get spiffy new wheels, I'd rather have a geothermal energy unit in our house. Signed, The Clapping-Fart Car Owner

    Professionals in the field will not get anything new from this book, but it is a good primer for anyone thinking of a geothermal system for heating & cooling their home, complete with an FAQ and list of manufacturers to help start one's search for a local contractor.

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

    If this book doesn't make you want to put a geothermal unit in your home, you're off your rocker. If this book doesn't make you want to put a geothermal unit in your home, you're off your rocker.
