Peak Oil?
• World oil discoveries peaked in the 1960s
• 28 significant oil producing countries (accounting for
about half of the world oil production) have passed the oil
production peak
• 16 of the world’s 20 largest oil fields have passed the
peak
• World oil supply capacity may peak in 2014
(Skrebowski)
Oil Consumption: US and China
• US Oil Consumption (2009): 19 million barrels/day
• China’s Oil Consumption (2009): 9 million barrels/day
• If China’s oil consumption grows annually by 400,000
barrels/day, China’s oil consumption will rise to 13
million barrels/day by 2020
• If China’s oil consumption grows at an annual rate of
7%, China’s oil consumption will rise to 18 million
barrels/day by 2020
• From 2006 to 2009, OECD oil consumption fell by 4
million barrels/day

Dealing with Peak Oil
• Energy Efficiency?
• Coal-to-liquids
• Biofuels
• Electricity
Energy Efficiency
• Long-term physical limit: transportation (400%)
• Short and medium-run: limited by the pace of
equipment/structure replacement
• Assumption: new capital stock reduces energy intensity
by 50%; new capital is 5% of the existing capital stock 
ENERGY EFFICIENCY RISES BY 2.5%
• Probable realistic energy efficiency growth rate:
2%/year
Coal-to-Liquids
• Two tons of coal contain the same amount of energy as
one ton of oil
• Coal liquefaction involves an energy loss of about 50%
• It takes approximately four tons of coal to make one ton
of oil
• To replace 10 million barrels of oil/day (annual
consumption of 500 million tons), it will take 2 billion
tons of coal (or 30% of world coal production)
Biofuels
• Biofuels currently replace about 1 million barrels of
oil/day (50 million tons of annual consumption)
• About one-third of the US corn production is committed
to biofuels
• If the world’s entire cropland (1.5 billion hectares) is
committed to biofuels, it can replace about 2,000 million
tons of oil (50% of world oil consumption)
• To replace 10 million barrels of oil/day (annual
consumption of 500 million tons), it will take 25% of the
world’s total cropland
Electricity
• Cannot replace fuels for trucks, ships, airplanes, tractors,
and oil feedstock used in chemical industries; requires
massive infrastructure transformation
• To replace 10 million barrels of oil/day (annual
consumption of 500 million tons), it will take 2,000
trillion-watt hours of electricity (or 10% of world
electricity generation)
• To generate 2,000 TWH of electricity, it will take 500
billion cubic meters of natural gas (15% of world natural
gas production)
• Or 280 giga-watts of new nuclear power plants (a 75%
expansion relative to the current nuclear power capacity)
• Or 900 giga-watts of new wind power (takes 20 years of
construction costing 2 trillion dollars)
• Or 1,500 giga-watts of new solar photovoltaic power
(takes 30 years of construction costing 8 trillion dollars)
Climate Change
• 2010 was the warmest year since 1880
• Global average surface temperature is now about 1C
higher than the pre-industrial time
• Current rate of global warming: 0.2C/decade
• Pre-industrial atmospheric CO2: 280 ppm
• Current atmospheric CO2: 390 ppm (rising at a rate of
2ppm/year)
• Climate Sensitivity (IPCC): a doubling of CO2 leads to
global warming of 3C
• Climate Sensitivity (James Hansen): a doubling of CO2
(taking into account ice sheet disintegration) leads to
global warming of 6C

Will Peak Oil Take Care of Global Warming?
BP Statistical Review of World Energy:
World Oil Proved Reserves: 180 billion tons
World Natural Gas Proved Reserves: 170 billion toe
World Coal Proved Reserves: 830 billion tones
Potential carbon dioxide emissions: 2.5 trillion tons
Emissions and Economic Growth
• Rate of emission reduction = rate of emission intensity
reduction – rate of economic growth
• Assumption: annual rate of emission intensity reduction
= 2%
• Global warming of 3-6C: emissions need to fall at an
annual rate of 1 percent  world economic growth rate <
1 percent
• Global warming of 2-4C: emissions need to fall at an
annual rate of 4 percent  world economic growth rate <
-2 percent
Total Social Product
Surplus product
Population’s basic consumption
Replacement of means of production used up
Capitalism and Economic Growth
• Pre-capitalism: surplus product was under (nondemocratic) social control  used for elites’ consumption,
wars, or religious activities
• Capitalism: surplus product was not under social control
 used primarily for capital accumulation
• Dominance of market competition  individuals,
businesses, and states are all driven to accumulate capital
 endless accumulation of capital (economic growth)
• Ecological sustainability  requires zero economic
growth  surplus product not used for accumulation 
social control over the surplus product + social choice of
zero economic growth
The 21st Century Crisis and the Future of Humanity
• Reform of Capitalism: capitalism with social equity and
ecological sustainability?
• End of Capitalism: what to replace it – socialism, postcapitalist feudalism, utopianism?
• Ecological Catastrophes – end of civilization, end of the
humanity?
