Energy Return on Energy Investment
1. Peak oil, declining EROI and the new
economic realities:
New limits to growth?

Can we learn anything from ecology?
In ecology, succession occurs after a disturbance. Production
(photosynthetic energy capture) increases rapidly and then becomes
asymptotic. Respiration (energy use) increases more slowly as biomass
increases. Eventually, energy use equals energy gain and the system
stops growing.

Revisiting the Limits to Growth After Peak Oil

American Scientist, Volume 97: 230-237
11. Why is this the case?
Why is the economic growth in the US (and
OECD and maybe the world) slowing down?
Are we just in an economic downturn or are we
on a slope?
?
?
12. If it is a slope (and it seems to be) what
might be the cause of that?
Our candidates:
Peak Oil (or rather declining rate of oil use)
Declining EROI
There is no longer cheap energy to feed the beast

• Geophysicist at
the Shell lab in
Houston, Texas
• In 1956, he
wrote a paper
with predictions
for the peak
year of US oil

26. I. DEFINITION of EROI (Sometimes EROEI)
Energy return on investment for an activity:
Energy delivered to society
EROI = __________________________
Energy put into that activity
Usually consider energy invested from society
27. Best First Principle
• Humans use high quality, low cost
resources before low quality, high cost
resources
(Ricardo)
• Best-to-worst ordering of resource
exploitation

58. CONCLUSIONS
1. Economic growth in the past has been highly
dependent upon growth in fossil fuels
2. We cannot assume this growth will continue
3. While technology is important and continuing, it
appears that depletion is trumping technology as
indicated by declining production and EROI
4. The U.K. is likely to depend increasingly on the EROI
of imported fuels
5. Our existing economic approaches and theories are
completely inadequate for understanding this
situation
70. Is oil the chicken or the egg?
4. Adjusting energy for quality
differences among fuel types
indicates causality running
from energy consumption to
GDP
Cleveland et al. (2000)
71. 3. But its not just energy that grows
the economy
72. Oil Prices are Lower During Expansions
Average Real Oil price from 1970 - 2008
73.
74. 4. Every recession since 1970 has been
preceded by a spike in the price of oil
82. Summary of the Facts
• Inexpensive energy has been used to provide
steady economic growth in the recent past
• We are finding less oil, and the oil we do find
is expensive, creating a volatile price situation

100. . It seems no one wants to hear these
things. I believe they are behind the
increasing financial problems we have
in Europe and US for we have been
clearly living economically beyond our
biophysical means. This is not to
negate greed, corruption and financial
malfeasance.
