The given bar chart delineates the percentage of an energy category, which can renew naturally, in the sum of providing energy within 4 nations over a 14-year period between 1997 and 2010.
In general, it is discernible that Iceland invariably took the significant lead in supplying renewable energy throughout the examined period. Notably, Iceland and Sweden’s percentage of alterative energy are upward ad contrary with two other countries.
Looking first of all at Sweden and Iceland, while the percentage of sustainable energy of Iceland is initially the highest in 1997, at around 45%, that of Sweden attributed to the lowest, at just 5%. In 2000, Iceland furnish more 15% that type of energy and the amount of renewable energy of Sweden experienced an significant increase. Over the next ten years, the number of green energy providing in Iceland still rose sharply, which widening the discrepancy with that of Sweden for more than 60% higher.
Turning to Turkey and Australia data, the percentage of clear energy delivered in Turkey is four times as much as Australian counterparts in the first year of the period. The proportion of Turkey gradually grew up in 2000, accounting for nearly 40%, whereas that of Australia witnessed a small decline. This trend for Australia data continously decrease in the next milestone, hitting a low at 4%. Finally, the amount of Turkey’s renewable energy saw a decrease, comprising more than 30%.
