The Decline in Energy Returned on Energy Invested, Net Energy, and Marginal Benefits

(p.37) 2 The Biophysical
Ending the Fossil Fuel Era

Jack P. Manno

Stephen B. Balogh

The MIT Press

In this chapter, Manno and Balogh articulate a biophysical logic that complements the social, political, and ethical arguments against the unfettered extraction of fossil fuels. They argue that making a sound and rational decision about the future of energy requires approaching this issue from a broad systems perspective. Expanding on the ecological economics concept of Energy Return on Investment (EROI), Manno and Balogh offer WROI, Welfare Return on Investment, with an emphasis on quality of life and lifesaving measures for the planet.

Keywords:   Energy Density, Energy Return on Investment (EROI), Welfare Return on Investment (WROI), Ecological Economics, Biophysical Economics, Net Energy, Threshold Hypothesis
