Main Findings
•
In the coming decades, the World’s and China’s
domestic energy resources will be unable to sustain
China’s rapid economic growth
•
China’s coal production is likely to peak by around
2025; oil production peak by 2015; natural gas
production peak by 2030
•
Even with optimistic assumptions of renewable
potentials, China’s energy supply will peak by 2030
and enter into decline thereafter
•
By 2020, China’s demand for energy imports will
impose an unacceptable burden on the rest of the
world and the growth in energy imports cannot be
sustained
•
Even with optimistic assumptions of energy
efficiency, China’s economic growth will slow down
sharply after 2020 and the Chinese economy will
decline in absolute terms after 2040

Peak Oil
•
World Oil Discovery Peak: 1960s
•
Peak Oil: US (1970); UK (1999); Norway (2001);
Mexico (2004); Russia (2007?)
•
Germany Energy Watch
Production Peak (2006)
•
ASPO: World Oil Production Peak (2008)

Oil
Hubbert Linearization
•
In 1956 M. King Hubbert predicted that the US oil
production would peak around 1970
•
For any nonrenewable resource, its production will
first tend to rise, and then tend to fall, before eventual
depletion
•
The production peak is likely to take place when
about half of the ultimately recoverable resource is
depleted
•
As the production level approaches the peak, a linear
relationship will be formed between the cumulative
production and the growth rate of the cumulative
production
•
A linear regression of the two variables result in
parameters that can be used to predict the ultimate
recoverable resource and the peak year
（ BP Statistical Review of World Energy: World Oil
Reserve 168.6 billion metric tons or 193.4 billion tons if
oil sands are included）
（BP Statistical Review of World Energy: China’s Oil
Reserve 2.1 billion metric tons）
China: Peak Coal?
•
BP Statistical Review of World Energy: China’s coal
reserve 114.5 billion metric tons
•
German Energy Watch Group: Peak Coal Production
2015
•
Dave Rutledge (Caltech, Chair of Division of
Engineering and Applied Science): China’s
remaining recoverable coal 88 billion metric tons
•
Hubbert Linearization suggests China’s remaining
recoverable coal to be 160 billion metric tons (Rsquare: 0197)
•
China’s Ministry of Land and Natural Resources:
China’s remaining recoverable coal 204 billion
metric tons (using this estimate and assume that the
recent production trend continues, China’s coal
production will peak before 2020)
China’s Energy Supply: From the Present to 2050
•
Peak Domestic Coal 2025; Peak Domestic Oil 2015;
Peak Domestic Natural Gas 2030
•
By 2050, 90% of the hydro technical potential is
exploited
•
Nuclear Electricity: generating capacity rises from
the current 7 GW to 60 GW in 2050
•
Renewable
Electricity
(Chinese
government
programs): Wind (100 GW, 2020); Biomass (30 GW,
2020); Solar (100 GW, 2030)
•
Renewable Electricity (2050 potential): 2,200 GW
(wind 1,000 GW; solar 1,000 GW; biomass 200 GW)
•
Imports: by 2020 energy imports rise to 16 percent of
world (ex. China) production of fossil fuels and
biofuels (China’s projected energy imports by 2020:
1.4 billion toe; China’s imports in 2007: 200 million
toe; US imports in 2007: 700 million toe)
Energy Consumption and Economic Growth
GDP = Energy Supply * Energy Efficiency
Economic Growth Rate
= Energy Supply Growth Rate + Energy Efficiency Growth Rate
Too Pessimistic？
•
Used the highest estimate of remaining recoverable
coal (and has not considered social and
environmental constraints)
•
Oil and natural gas peak estimates are consistent with
consensus
•
Hydro: near full exploitation of technical potential
•
Nuclear: the world’s existing reserve of uranium will
only last 30-70 years
•
Renewable electricity: 10 times of the Chinese
government’s long-term goals or 3 times of China’s
current total electricity generating capacity
•
Imports: extremely optimistic
•
Energy Efficiency: projected to exceed the present
European/Japanese level by 2050
