Here at Things Are Good we like geothermal energy and countries that use it. The USA could be on the list in the future!
Researchers from SMU that have received funding from Google have released a map that shows the potential of geothermal energy production in the continental United States. The conclusion is that there is more potential energy in geothermal than previous thought and the technology exists today to access it and provide more than enough energy for the nation’s consumption on geothermal alone!
In this newest SMU estimate of resource potential, researchers used additional temperature data and in-depth geological analysis for the resulting heat flow maps to create the updated temperature-at-depth maps from 3.5 kilometers to 9.5 kilometers (11,500 to 31,000 feet).
This update revealed that some conditions in the eastern two-thirds of the U.S. are actually hotter than some areas in the western portion of the country, an area long-recognized for heat-producing tectonic activity. In determining the potential for geothermal production, the new SMU study considers the practical considerations of drilling, and limits the analysis to the heat available in the top 6.5 km (21,500 ft.) of crust for predicting megawatts of available power.
This approach incorporates a newly proposed international standard for estimating geothermal resource potential that considers added practical limitations of development, such as the inaccessibility of large urban areas and national parks. Known as the â€˜technical potentialâ€™ value, it assumes producers tap only 14 percent of the â€˜theoretical potentialâ€™ of stored geothermal heat in the U.S., using currently available technology.
