The bar chart illustrates the percentage of renewable

energy

in Australia,

Sweden

,

Iceland

and Turkey between 1997 and 2010.

Overall

, there were increases in the share of renewable

energy

in

Iceland

and

Sweden

, with

Iceland

being consistently the largest figure and having a far distance from Australia and

Sweden

. It is

also

clear that the proportion of renewable

energy

in Turkey was at the second level throughout the period. Looking first at areas with rises in the percentage of renewable

energy

, 45% of renewable

energy

in

Iceland

in 1997, after which it experienced considerable growth to 60% in 2000 and reached the highest point at exactly 70% in 2010. A similar trend, but to a lesser extent about one per eight compared to

Iceland

, was seen in

Sweden

. Just 5% of renewable

energy

in

Sweden

in 1997, before

this

figures for growing to 9%

at the end

of the period. Turning next to the other two areas, the share of renewable

energy

saw a slight rise from 38% in 1997 to a peak of exactly 40% in the next three years, but

subsequently

it decreased to 32%

at the end

of the time frame. A drop in the percentage of renewable but at a rate more steady than in Turkey

also

was seen in Australia, with the figures falling from 9% at the beginning to 3% in the next thirteen years.
