Some way behind was Iceland, which started at approximately 52% in 2000, rose to a peak of about 60% in 2004, and then fell slightly to around 55% in 2007.
Germany experienced a steady increase in the percentage of renewable energy, rising from about 10% in 2000 to around 15% in 2004, before reaching nearly 20% in 2007. In contrast, Australia had the lowest figures throughout the period, starting at roughly 7% in 2000 and increasing gradually to around 10%. In 2007, the figure showed a downward trend to 9%.
