Are we running out of energy efficiency? Are we running out of energy efficiency? Presentation Transcript

  • Discussion Webinar June 2008 Are we running out of energy efficiency?
  • Energy Efficiency – setting the scene
    • 20% primary energy saving by 2020
    • (20% CO2 emission reduction)
    • National Energy Efficiency Action Plans
    • High energy costs
      • Rising (energy) costs
    • “ Cheapest form of energy you can get”
    • Competitiveness
  • Problems
    • Solutions can be simple
      • Switch ON or OFF
      • Technology is available
      • “ Frequent flyer” points
    • Energy efficiency doesn’t exist!
    • There is no low-hanging fruit! ($100 bill joke may be real)
    • Energy is too cheap to be worth saving
    • Time consuming and delivered in small packages
    • Behavioural change
      • The more you consume the cheaper it gets
  • Facts
    • 1973 oil shock
      • US would be spending 12% of GDP instead of current 7%
      • Energy intensity down by 30% in France and 40% in Germany
    • US: average fridge price has fallen by more than half since the 70s
      • Energy efficiency has improved by 75%
      • Size of average unit increased
      • Ownership has dramatically increased
  • World Energy use
  • Energy use 50% higher without past energy savings
  •  
  •  
  •  
  • Factor 4 improvement
  • Factor 6+ improvement
  • Factor 100,000 + improvement
  •  
  • Life style improvement
  • Life style improvement (China)
  •  
  • How much energy do we need? 5 toe/year per capita 10 billion people by 2100 = 50 Gtoe/year Currently:12 Gtoe/year

  • Review
    • Negajoules
    • Energy Efficiency improvement
      • Heavy industry sectors
      • Automotive
      • Buildings & Glass windows
      • Lighting
      • Computers
    • Life style improvement
    • Appliance ownership
    • World population
    • Energy needs
    • Energy/fuel cost
    Discussion: Are we running out of energy efficiency?
  • The discussion
    • How much energy do we need?
    • Have we run out of energy efficiency? If not, how much potential is still there to grasp?
    • And why is energy efficiency so hard to pursue?
    • Is it more costly to invest on energy or energy efficiency?
    • What is the worrying trend? (Energy consumption, population growth, life style improvement)
    • What have we learnt from the past?
  • Can we still save energy?
