low-grade energy resource

Geothermal in the U.S.: Some argue that geothermal energy is a dilute, low-grade energy resource that is too small to make a difference. a. Given that the U.S. consumes about 100 quads annually, estimate the minimum mass of hot rock needed to meet annual demand assuming the rock mass is at 200 °C initially. b. Given that the average geothermal temperature gradient is 20 °C/km for the US, how much thermal energy is stored in rock to a depth of 10 km corresponding to depths that can be reached using conventional drilling technology? c. An ambient temperature of 25 °C can be assumed. The surface area of the U.S. is 9.37x106 km2 . You can assume that the rock mass under the surface of the US is solid granite with a density of 2500 kg/m3 and a heat capacity of 1000 J/kg K
