Getting to grips with Energy Efficiency

This is the first post of a series I intend to write on the energy efficiency theme, of which this one is a general introduction, and the following ones will keep going into more specific matters and tips.

There are obviously many different ways of measuring macro-efficiency, but I personally tend to prefer economies energy intensity (the GDP/Energy ratio) to showcase it. In the graph below you can see how much energy did each country use to produce a given amount of wealth when compared with Japan during 2009.
