Abstract

We have applied standard energy analysis to 4 types of geothermal-electric technologies: liquid dominated, hot dry rock, geopressure, and vapor dominated. We find that all are net energy producers, i.e. they have an energy ratio exceeding unity, where energy ratio = net electric energy produced over lifetimeprimary nonrenewable energy inputs over lifetime (excluding geothermal energy itself)
