Assessing the global environmental sources driving the geobiosphere: A revised emergy baseline

A Monte Carlo simulation that includes the revised solar exergy flow of geothermal inputs and uncertainty in the flows yields SERs of 26,300 seJ J−1 and 5500 seJ J−1 for tidal and geothermal sources respectively. The solar exergy remains 3.6 E+24 sej y−1, while the solar equivalent exergy of tidal and geothermal sources were 3.1 E+24 seJ y−1, and 5.4 E+24 seJ y−1 respectively, resulting in a GEB of 12.1 E+24 seJ y−1.
