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

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

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

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

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?

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?
