I came across the Energy Architecture Performance Index 2013 report (evaluation of energy systems of 105 countries) done by World Economic Forum. From the summary:
The EAPI measures 16 indicators aggregated into three baskets relating to the three imperatives of the energy triangle to which energy architecture should contribute: economic growth and development, environmental sustainability, and access and security of supply. The EAPI both scores and ranks each country’s current energy architecture based on how well it contributes to these imperatives.
It is interesting that according to this aggregated index, France’s energy system architecture ranks 3rd. About 80% of France electricity is from Nuclear power. So the alchemy of “energy triangle” lies in nuclear power?!
