The chart shows the proportion of renewable energy in total energy supply in four countries from 1997 to 2010
Task
The bar chart compares the proportion of renewable energy used in Australia, Sweden, Iceland and Turkey in three years, 1997, 2000 to 2010.
It is clear that Iceland had the highest renewable energy consumption over the period shown. The percentages of this energy source in the total energy supply increased in Iceland and Sweden but decreased in Australia and Turkey.
In 1997, nearly a half of total energy consumed in Iceland was renewable, which climbed gradually by around 12% each period and still ranked top. In comparison, renewable energy accounted for roughly 37% of the total supply in Turkey in 1997, but then this figure rose to just over 40% in 2000 before a decline to around 34% in 2010.
Australia and Sweden only used a trivial percentage of renewable energy. Under 10% of the total energy supply in the former was renewable, which declined marginally to a half in 2010. However, the opposite was true for Sweden.
