The proportion of reusable energy supply
The bar graph given compares the total percentages of reusable energy supply in four different countries: Australia, Sweden, Iceland and Turkey, between 1997 and 2010. Overall, Iceland and Turkey showed higher rates of renewable energy use compared to Australia and Sweden.
In Iceland, the proportion of renewable energy supply increased throughout the entire period. The figure for Iceland started the period at about 46%, after that it rose considerably to 60% over the next 3 years. By 2010, it experienced a notable increase of 10 percentage points, reaching the highest level during the entire period. As for the trend for Turkey, having gone up to 40% in 2000, it declined rapidly.
In contrast to Iceland and Turkey, the proportion of total energy supply in both countries was lower than 10%. The figure for Australia showed a continuous fall while the supply of energy in Sweden grew over a 13-year period. In 1997, Australia’s renewable energy proportion was about 9% (its highest point), but it declined to 4% by 2010 (its lowest). However, the total energy supply in Sweden experienced a continuous rise reaching nearly 10% in 2010.
