Low energy intensity may be a sign of developed industrial and societal structure

3 Pros:
•    For creating scenarios, E/GDP is a useful parameter to connect both
•    E/GDP is policy-dependent, thus close to political measures
•    E/GDP change rate is an evolutionary effect, thus similar across countries

3 Cons:
•    A very gross parameter
•    Not near to everyday experiences
•    Rather limited to academic discussions
