The given bar graph demonstrates the amount of renewable energy supplied from four district nations; Australia, Sweden, Iceland, and Turkey between 1997 and 2010. Looking at the overall trend, it is clearly shown that Iceland contributed by far the most renewable energy, while Australia and Sweden attributed to the least among the countries.
Interestingly, Australia and Sweden were the countries, which had the minor proportion in the energy supplyment, the figures standing all under 10 throughout the period. The Australia experienced a downward trend, while Sweden showed exactly the opposite trend.
In stark contrast, It was the Iceland that took the most amount of propotion in supplying renewable energy. It started slightly over 40 in the initial year, ending at exactly 70 in the final year. When it comes to Turkey, it started at the
similar level with that of Iceland at roughly below 40, however, the energy supplyment tend to decrease in the end of the year to around 30, which was almost the half of that of Iceland's total in 2010.
