Energy Return on Investment of Major Energy Carriers: Review
Net energy, that is, the energy remaining after accounting for the energy "cost" of extraction and processing, is the "profit" energy used to support modern society. Energy Return on Investment (EROI) is a popular metric to assess the profitability of energy extraction processes, with EROI > 1 indicating that more energy is delivered to
Return on Investment (ROI) | Formula + Calculator
The net return on the PP&E investment is equal to the gross return minus the cost of investment. Net Return = $75m – $50m = $25m. The net return of $25 million is then divided by the cost of investment to arrive at the return on investment (ROI). Return on Investment (ROI) = $25m ÷ $50m = 50%. Given the $50 million net
