Overall, the Iceland was the dominant country with renewable energy. Turkye was also using as much as Iceland, but less than 50% in the all periods. However, Australia and Sweden were the lowest countries, by using not more than 9%.
In contrast, between 1997 and 2010, Iceland’s renewable energy shot up over 20%, and getting more than 60% of total energy supply. At the start, Turkye also increased be 2%, but in the end fell from 41% to 32%.
