Transcript of "Insead Alumni Energy Network 22nd October 2011 by Benjamin Warr"

  1. 1. Dr Benjamin Warr, Senior Research FellowINSEAD Social Innovation Centre Sustainability GroupAlumni Reunion Energy Network Presentation22nd October 2011Energy and Wealth Creationbenjamin.warr@gmail.comhttps://sites.google.com/site/rexsgate/
  2. 2. Topic and Objectives• Reconsider some assumptions of the role of energy• Provide alternative assumptions: energy as a driver of growth• Supply and efficiency are critical for growth• Supply challenges lay ahead• Efficiency promises are blocked, ignored and unfulfilled
  3. 3. Standard Paradigm• Closed system in equilibrium with no wastes• Growth occurs through accumulations of capital and labour• Both increase in productivity at an exogenous rate (TFP) Purchases Production of Consumption of Goods and Goods and Services Wages, Rents Services Invested (Energy Generating) Capital
  4. 4. US GDP actual vs. modeled using a 3- factor Cobb-DouglasGDP Index (1900=1) 25 20 US GDP 15 10 SOLOW RESIDUAL (TFP) 5 Cobb-Douglas 1900 1920 1940 year 1960 1980 2000

  6. 6. Something is missing ?• Unable to explain historic growth rates.• Exogenous unexplained technological progress is assumed, hence growth is assumed to continue.• No link to the physical economy, only capital and labour are productive.• Energy, materials and wastes are ignored.• Energy availability is overcome by investments in capital.

  17. 17. Concerns• Availability and supply of energy (and specifically oil) • low price elasticity – people need it • increasing costs of production – harder to find and obtain • weak substitutability – alternatives unavailable for various reasons • increasing demand growth rate, global energy equity and poverty alleviation• The rate of efficiency improvements • imperfect markets (externalities, subsidies) • wealth effects, the energy-poverty nexus imperative • lock-in and current technology asymptotes • climate, health & safety (real and unreal concerns) • (lack of access to finance)

  27. 27. Summary• Neoclassical growth theory does not describe the natural resource dependency of growth.• We model economic growth with useful work as a factor of production. This explains past growth well.• Economic growth need not be a constant percentage of GDP. It can be negative.• Future sustainable growth in the face of peak oil depends on accelerating energy (exergy) efficiency gains and alternative supplies.• Future efficiency gains may be inexpensive if existing double dividend possibilities are exploited.
  28. 28. A path forward – a neo-liberal solution• These results provide the evidence to justify macro-economic (risk-management) policies: • energy security through appropriate long-run renewable energy policy • energy productivity through short-term energy efficiency drive • economic stimulus through ‘green’ jobs creation• Large but avoidable inefficiencies exist corresponding to significant departures from the optimal equilibrium growth path that is commonly assumed.• Eliminating inefficiencies can create “double dividends”
