•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

How much energy do we need?5 toe/year per capita
10 billion people by 2100
= 50 Gtoe/year
Currently:12 Gtoe/year

Discussion: Are we running out of energy efficiency?
www.leonardo-energy.org
The discussion
1. How much energy do we need?
2. Have we run out of energy efficiency? If not, how much potential is still there to grasp?
3. And why is energy efficiency so hard to pursue?
4. Is it more costly to invest on energy or energy efficiency?
5. What is the worrying trend? (Energy consumption, population growth, life style improvement)
6. What have we learnt from the past?

Can we still save energy?
