Texas has more geothermal energy available to its citizens than they realize. The ability to cool and heat homes using ground source heat pumps is a way to use the ground temperatures right below us to offset the normal electrical needs. Currently in the US there is over 7000 MWt of energy offset by geoexchange systems.

Because of the Balcones, Mexia, Luling, Talco Fault trend that runs from Laredo to San Antonio, Austin, Byron, Dallas, and on into east Texas, there are areas with water hot enough (75 – 140°F) for direct use. This could be used for agriculture, aquaculture, direct hot water, spas, and industrial drying.

Texas also has the capacity to generate electricity from the existing oil/gas wells that are producing fluids as well as working with abandoned wells and refracturing them to increase water production. With new binary turbine technology, a small unit can be added to a single or multiple wells to extract the heat from the fluids and generate electricity. For this to work, temperatures need to be over 200°F and have a cold water source nearby. In Texas 1000s of wells are producing fluids over 200°F, in fact some of the south Texas wells have fluids over 400°F. Using these resources, the state of Texas will be generating renewable electricity from geothermal energy in the near future.
