While traditional geothermal energy relies on finding natural pockets of hot water and steam, EGS fractures the hot rock, circulates water in its system, and uses the steam created from the process to create electricity in a turbine.
According to an MIT report on EGS, only 2% of the heat beneath the continental US between 3 and 10 kilometers (depths we can reach with current technology) is more than 2,500X the annual energy use of the United States.
