Energy Return on Investment: A Comprehensive Guide

EROI is defined as the ratio of the energy returned from an energy-producing activity to the energy invested in that activity. This metric provides insights into the efficiency and viability of

Energy return in running shoes explained

Energy return in running shoes refers to how efficiently the midsole foam rebounds after being compressed during a step. Instead of absorbing all impact as heat, a running shoe stores

Energy Return on Investment (EROI): What it is, how it is calculated

Discover what the energy return on investment (ERI) is, how it is calculated, and why it is key to the energy transition.

Estimation of useful-stage energy returns on investment for

A common metric to quantify the net energy returns of a given energy system is the energy return on investment (EROI), defined as the ratio of the energy delivered divided by the energy...

Energy Return on Investment: Setting the Record Straight

In a recent Nature Energy paper, Brockway et al. (2019) set the record straight.

Energy return on investment

In energy economics and ecological energetics, energy return on investment (EROI), also sometimes called energy returned on energy invested (ERoEI), is the ratio of the amount of usable energy (the

Energy Return on Investment (EROI): Overview, Calculations

Energy Return on Investment (EROI) is a ratio for describing a measure of energy produced in relation to the energy used to create it. For instance the ratio would illustrate how much...

Energy Return → Term

At its most fundamental, Energy Return, often abbreviated as ER, represents the ratio of the amount of energy obtained from an energy resource to the amount of energy expended to obtain it.

Rebalancing “Return on Equity” to Accelerate an Affordable Clean Energy

The clean energy transition will require new capital investments. However, evidence suggests that ROEs are higher than the return required to fund utility capital plans, based on an

Rate of Return Regulation Revisited

Utility companies recover their capital costs through regulator-approved rates of return. Using a comprehensive database of utility rate cases, we find a significant premium for regulated returns on

A related recent concern is energy cannibalism, where energy technologies can have a limited growth rate if climate neutrality is demanded. Many energy technologies are capable of replacing significant volumes of fossil fuels and concomitant greenhouse gas emissions. Unfortunately, neither the enormous scale of the current fossil fuel energy system nor the necessary growth rate of these technologies is well understood within the limits imposed by the net energy produced for a growing industry. This technical l
