Analyzed since 1980 by the team at economic Research group Edmond-de-Rothschild, the progress of the ecological transition are constant but insufficient. Switzerland, Colombia and Sweden are at the top of this ranking, where France gets an honourable seventh place thanks to nuclear power and renewable energy. "France has an energy mix consisting of 52% of fossil energy compared to the global average of 85 percent," notes Lisa Turk, an economist specializing on the United States and the environment in Edmond Rothschild. Germany is only the 28th, China 41st, and the United States, 48èmes.

The swiss Confederation gets the best index of energy efficiency thanks to hydro and nuclear, which cover 45% of primary energy needs (non-transformed) in the country . If our neighbours to consume individually a lot of energy, the countries, globally, employs only 50.5% of fossil energies.

The unexpected presence of the British on the second place of the podium is linked to a primary energy consumption of individual less than the world average, coupled with a significant use of hydroelectric power. Sweden, the third, the benefits full of the rapid implementation of regulations severe. Now, the use of fossil fuels there is more than 32.6 per cent .

At the other end of the table, which consists of 60 countries in total, Qatar occupies the last rank. It is preceded by Singapore and the united arab Emirates. The study indicates that Qatar has a energy consumption per person 100 times more important than Bangladesh, which is the country with the lowest primary energy consumption per person.

Four major factors have been taken into account for the realization of this study: energy consumption per capita, CO2 emissions per person, the share of consumption of fossil energy in the total energy consumption (energy mix) and energy efficiency, that is, the GDP generated per unit of energy used .

To improve the ecological transition world, Lisa Turk advocates on the one hand the improvement of energy efficiency (transportation electrification, energy efficiency upgrades...), and on the other hand an improvement of the energy mix. In fact, according to the report of the international energy Agency's (IAEA) released Tuesday, the energy requirements will have risen more than 25% by 2040 because at the same time, the global population will have increased by 1.7 billion people.
