The EROI system of evaluating energy exploitation from various sources is based upon
A)the market price of the energy involved.
B)the environmental damage likely to be caused by the extraction process.
C)the ratio of energy extracted to energy invested in the extraction process.
D)the amount of heat produced by using a unit of the energy in question.

Question

Quizplus · Accepted Answer

The EROI (Energy Return on Investment) system evaluates energy exploitation from various sources by calculating the ratio of energy extracted to energy invested in the extraction process. It does not consider the market price of the energy involved or the amount of heat produced by using a unit of the energy in question. While the environmental damage caused by the extraction process may be a factor in determining the viability of a particular energy source, it is not directly used in the EROI calculation.
