Photo-Voltaics (PV) is an energy source where this problem has been more acute. Equipment and installation prices collapsed four or five fold since 2010, but published EROEI studies have not converged; in fact it appears they dispersed even further.
Theoretically, whatever is published in a scientific journal should go through a rigorous review process that ensures that it is correct and reliable. Unfortunately, it doesn’t work that way.
The EROI of our various energy options, and its associated issues, may be the most important issues that will face future civilizations.
Solar photovoltaic (PV) systems generate "free" electricity from sunlight, but manufacturing them is an energy-intensive process.
