Peak Energy and the Limits to China’s Economic Growth Dr. Minqi Li, Assistant Professor Department of Economics, University of Utah Salt Lake City, UT 84112 E-mail: [email protected] Website: www.econ.utah.edu/~mli Presentation at the “China and the Chinese Study Group” October 6, 2008 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 World Primary Energy Consumption(2007) Oil Coal Natural Gas Nuclear Hydro Renewable Electricity Biofuels 36.6% 29.4% 24.9% 5.8% 2.5% 0.6% 0.2% China’s Primary Energy Consumption(2007) Domestic Coal Domestic Oil Domestic Natural Gas Hydro Nuclear and Renewables Imports and Stock Change 71.8% 10.4% 3.5% 2.3% 0.9% 11.2% 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) Group: World 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
