I started writing the materials section today. There is more info to come regarding what we are planning to use and why, so please check back.

Geo-Thermal vs. Gas and Conventional AC
The decision to put in a geo-thermal system was not an easy one. While geo-thermal is often presented as a clean heat and cooling source because it is not burning a fossil fuel on-site, it needs electricity. So until electricity is produced by clean sources, this statement is not true.
Before we decided on geo, we spent sometime calculating the power needs and greenhouse gas output of the system and how these compared to a more conventional gas heater and electric AC system. We found that a geo-thermal system is cheaper to run and will produce less greenhouse gases than a gas fired heating system. Checkout the details in the Energy Use page.
