1 Energy producers have a high energy use, partly because energy tends to be much cheaper. ( 2 See cost of petrol per country). 3  The country with the highest energy use per capita is Iceland. 4  A significant part of Icelandâs energy use is thermal energy from naturally occurring volcanic springs.he list shows a huge disparity between the highest energy users and the lowest. It is worth bearing in mind: 1  Colder countries understandably have a relatively higher use of energy because more resources are devoted towards heating. 2  Energy producers have a high energy use, partly because energy tends to be much cheaper.
