Task 1: The chart shows the proportion of renewable energy in the total energy supply in 4 countries from 1997 to 2010. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The bar graph describes the percentage of renewable

energy

in the total

energy

supply of 4 nations from 1997 to 2010.

Overall

,

while

recyclable

energy

usage in Sweden and Iceland increased, the opposite trend can be seen in that of Turkey and Australia. Noticeably, Iceland has the largest proportion throughout the entire period. Looking into details, the figure of Icelandic power usage stood at over 40% at the start of the period; it skyrocketed to 60% in 2000, prior to reaching a climax of 70% in 2010.

Similarly

, Swedish renewable

energy

constituted around 5%,

to begin

with, preceding a subtle rise in 2000 and

finally

peaked at roughly 10%

to conclude

the course. With regard to Australia and Turkey, the portion of the former was just south of 10% in 1997 and gradually fell until hitting its trough at approximately 5% in 2010. Inexhaustible power sources accounted for nearly 40% of the Turkish

energy

supply in 1997.

This

fraction reached 40% in 2000 and plummeted to almost 30%

at the end

of the timeline.
