Managing the Peak Fossil Fuel Transition: EROI and EIRR

Current renewable energy technologies must be adopted in conjunction with aggressive Smart Growth and Efficiency if we hope to continue our current standard of living and complex society with diminished reliance on fossil fuels. These strategies have the additional advantage that they can work without large technological breakthroughs.

In this post I will talk about a topic which is likely familiar: Energy Return on Investment or EROI. I will also talk about Energy Internal Rate of Return (EIRR), a measure which is similar to EROI, but reflects how quickly society gets its energy return back from its energy investment.
